Ornamental Berries



ORNAMENTAL BERRIES

Beauty in the garden presents itself in numerous ways throughout the year. The impact of bold bright summer flowers is replaced in autumn with brilliant leaf colours as well as berries, fruit and hips. Most plants reproduce and spread by means of seed dispersal and have all developed amazing methods to ensure their success amongst the competition.

Plants need to ensure that their seed is spread well away from the parent plant so some have developed wings e.g. sycamores and maples, some have hooks such as sticky willie, and some open with an explosive power to shoot seeds good distances, e.g. brooms and gorse.
Chestnuts and oaks provide a food source for squirrels who collect the seed and dig holes in the ground to store them for the winter. There is always a good chance that some will survive the ravages from the hungry squirrel and grow into a tree.
The ornamental fruiting trees and shrubs started of as edible fruit for wildlife who travel away from the source eating the fruit on the journey and disperse fertilised seed in their droppings. Humans have played a role in dispersal of apple trees grown from seed along railway embankments as the apple cores were thrown out of the windows from older steam engine trains.
People have grown plants for eating for generations and realise that there is also a visual pleasure in seeing a tree or shrub in full crop with brightly coloured fruits.
Nurseries and plant breeders have taken this a stage further in developing new improved varieties and selecting the best clones to extend the available range of ornamental trees and shrubs with impressive displays of fruit.

Trees

When I was selecting suitable apple trees for my garden in Dundee I decided that they would need to be bright red as well as having excellent eating and storing qualities. Discovery is my early, Red Devil my main season and Fiesta and Red Falstaff my lates for storing, but while on the tree they all provide a fantastic display of bold colour.
Katy and Scrumptious are also very good.
However if a good display is more important than cropping potential try some of the ornamental crab apples such as Malus John Downie or Golden Hornet. After a while if you are tempted to use the fruit they will make an excellent jelly.
For those who are more patriotically Scottish a rowan tree will be high on the list. In past times they were necessary to ward off evil spirits, but old traditions die out and now they are grown in numerous forms for a very wide range of ornamental berries and autumn colour.
The common species, Sorbus aucuparia is grown all over Scotland and has eye catching scarlet foliage in autumn with a huge crop of scarlet berries which dont last too long as the birds just love them. The variety Sheerwater Seedling has been bred for its upright growth making a perfect tree avenue which does not interfere with traffic movement.
The yellow, pink and white berried rowans give a longer display as birds are not in a hurry to devour them like the red fruited types.
Joseph Rock has yellow berries amongst scarlet foliage, Sorbus cashmiriana has white berries and both Sorbus hupehensis and vilmorinii fruits start pink then slowly change to white tinged pink.
The genus Sorbus also includes the whitebeams which have broader grey leaves and scarlet berries which can last a long time. They make very impressive bold trees. The best ones are Sorbus aria lutescens and majestica where the grey summer foliage turns golden in autumn.

Berried Shrubs

Holly grows to a small tree size and is evergreen and will fruit in most years. It is very popular for a festive decoration around the home, is very easy to grow, but is not too fast.
Coming down the scale in size the Cotoneaster genus grows from a small tree such as C. frigidus to ground cover such as C. dammeri. They all get covered in bright red berries that last well into winter. The species C. horizontalis has a herring bone pattern that really excels when frosted. It is very useful for ground cover as is the variety Autumn Fire though it can be quite rampant. Cotoneaster simonsii is a very useful medium sized shrub for screening, but its prolific red berries get eaten and carried by birds all over the garden. It would seem that almost every seed wants to germinate and grow. This can be a problem.
Berries come in all colours from the white snowberry, Symphoricarpos albus, the violet purple Callicarpa bodinieri, the deep blue black Mahonia aquifolium to the bright orange sea buckthorn, Hippophae rhamnoides.
Sea buckthorn fruits are displayed on a silver grey feathery foliage that is great in maritime places as it tolerates sea spray and dry sandy soil conditions. It is a popular plant for vandal prone areas too, as it has a lot of thorns, and its strong root system and ability to sucker makes it useful to stabilise steep slopes and river banks. Breeders have been busy growing plants that can be easily harvested as the edible berries are very healthy once processed into juices and jams and essential oils are extracted from the seeds. It is also used in cosmetics and even in baby foods. The edible berries are very high in vitamin c,  but may have to be cooked in some recipe to get the best flavour from them.
Another excellent evergreen ground cover plant smothered in red, pink, lilac and white berries is the Pernettya. The berries last all winter until they get sweetened up for consumption by birds in late spring when there is precious little else for them to eat
The plants are female so you will need a male pollinator to ensure a good crop of large berries. You may have to order a male plant as they do not have sales potential in nurseries if there are no berries on them. Some species of male Pernettyas do however produce some berries as they may have a slight androgynous tendency.
It doesn't just happen to humans.
There is quite a bit of controversy as to whether the fruit is edible. For some native south American Indians Pernettya fruit was a major food source in summer and winter and different species were reported to have hallucinogenic chemicals or could make you intoxicated. The North Carolina State University studies reported the whole genus highly toxic and warned they may be fatal if eaten.
My local blackbird seems happy to gulp them down every late spring and always flies of in a straight line. He probably hasn't read the report.
Skimmia has always been popular as an evergreen low growing shrub with red berries. It is also dioecious so you need a male pollinator for the berrying female plants.

Roses

It is the common practise to remove the seed heads after flowering to conserve the plants energy for flower production, but some rose types have very attractive large bright red hips.
Do not remove these hips as they will be the attraction well into winter. There are many varieties, but they mostly come from the two species, Rosa, rugosa and Rosa moysii.

Climbers

The Firethorn, Pyracantha comes in many varieties with red, orange and yellow berries. These are produced quite prolifically on tall thorny evergreen bushes which are usually treated by pruning to grow as a wall climber. Birds love the fruit, so although the display is short lived it is quite stunning for a few weeks.
The outdoor ornamental grape vine, Vitis vinifera Brant produces numerous small bunches of black sweet grapes. It is quite vigorous but is easily kept under control with pruning. It is best trained along wires on a south wall. Autumn colour of the large vine leaves is brilliant.

Autumn Colour



AUTUMN COLOUR

A gardeners world has always entailed a fair bit of energetic graft, but then later you reap the reward. It may be the tasty fresh produce you have grown or the beautiful plants now looking their best, or a tranquil spot in which to relax in a sunny corner. If only you could ignore that never ending voice in your sub-conscious reminding you of that weed that needs removing, the broken fence to repair, a few plants needing potted or some other job from a long line of tasks that never end. However, summer is gone, the sun lounger is in store, so  topping up the sun tan is no longer an option and a new set of tasks for autumn is reaching priority status.
However, autumn does come in a brilliant blaze of colour that can take your breath away.
When the garden is being planned and planted up in the early years, this is the time to consider good plants for autumn colour as the best are usually trees or shrubs that need careful thought to allow them space to grow. Your garden size will determine what you can select.
I usually start by looking at the space for a tree or two. They come in all sizes so it is not difficult to find an appropriate list suited for shelter, screening, blocking unpleasant eyesores, or specimens to be admired. In UK most trees, other than conifers are deciduous so there is plenty scope for colour when they lose their leaves in autumn.

Brilliant trees

If you are blessed with a large garden you can indulge in any amount of forest trees with excellent autumn colour from the scarlet red oaks, bronze beech, golden maples and sycamores, horse and sweet chestnuts, lime, poplar, and even some elm if you are happy to risk the ravages of any remaining Dutch elm disease. They will all give a brilliant display in the autumn, but do some research before you buy as there is always some outstanding varieties within any one type.
It is always hard to pick a favourite but Acer cappadocicum rubrum is hard to beat if you can find one.
There are a few deciduous conifers that put on a dazzling display in autumn. Larch is the most frequently used, but try to find space for the Dawn Redwood, Metasequoia glyptostroboides, the swamp cypress, Taxodium distichum,  or the maidenhair tree, Ginkgo biloba. These are all large trees ultimately though some are slow growing and worthy of a place for ten years or so before they get too big.

Smaller gardens can still enjoy a wide range of good autumn colour with other species such as rowans, whitebeams, cherries, upright forms of hornbeam, liquidamber, amelanchier, maples and  birch. There are very many different forms, sizes and attributes for all of these trees, so as tree planting is for the long term do some research before making your purchase.

Dazzling shrubs

There are just as many types of shrubs as trees coming in all sizes from ground cover to small trees. They are used to form boundaries, hedges, and as ground cover to smother weeds. Some give shelter and privacy and are often mixed into shelterbelts, windbreaks and woodland fringes to add variety, interest and colour. Some types can be used on steep banks to prevent soil erosion with added benefit of providing food and shelter for wildlife.
Shrubs are often grown for their flowers or other features and good colour in autumn is a bonus. Deciduous azaleas have brilliant autumn colour as well as dazzling scented flowers in spring. Contrast them with the smoke bush, Cotinus coggygria which turns a deep scarlet.
However the plant with the widest range of brilliant colours must belong to some of the Japanese maples. I grow several of these, but Acer palmatum Sangokaku is not only fantastic in autumn but also has bright red stems that glow in the sun all winter.
Autumn is also a time when the heather garden attains bright scarlets and golds on many of the Callunas.
Then don't forget the fruit garden as the blueberries brighten up at leaf fall as well as the saskatoons and chokeberry, Aronia melanocarpa. The latter is fast becoming popular as demand for quality superfood increases. The Aronia may only be known as an ornamental large shrub with almost edible berries and excellent autumn colour at present, but its fruit quality is at the highest level for anti oxidants.
My two best climbing plants for autumn colour are the  Virginian creeper, Parthenocissus and the ornamental grape vine Vitis vinifera Brant. Careful with the former as it can be very vigorous and grow very tall, and Vitis Brant is also vigorous, but easy to keep in check with pruning. It will need a support to cling to with its tendrils. Its leaves turn scarlet and gold in autumn and its fruit bunches may be small but they are delicious eaten fresh or as a juice extracted from the fruit and kept in the fridge for up to two weeks. Surplus juice can be frozen.
Now we have enjoyed some blissful moments amidst the colourful gently falling leaves our thoughts go back to the next job needing attention

Autumn tasks

Those once admired leaves have now dropped down and will need raking up, and then this is the last chance to remove weeds before winter begins. I always like to go into the winter with weed free soil. A lesson from history. Hand weeding frosted flower beds in Dawson Park in winter 1960 was not an awful lot of fun. A passing lady walking her dog in the park was overheard telling her friend, “the patients do a marvellous job “
This is also a good time to spread a mulch of rotted compost on those borders planted with bulbs. Once the bulbs begin to emerge it is too late to put any compost on without doing some damage.
Garden tables and chairs can now be brought inside to protect them from winter weather, as opportunity for an outdoor coffee break is only reserved for the hardiest of patients.

Renovate lawns

Lawns may be purely functional as a place for the dog and kids to play on, or it may be a surface of excellence maintained to the highest level. The mower usually determines the standard, ie. use a rotary for the normal suburban lawn, but a cylinder with grass box for the perfect lawn with stripes. To keep the high standard of surface, autumn renovation work is an essential routine. Any broad leaved weeds will have been removed during the growing season, but moss can be a problem in autumn. Spreading lawn sand is the normal practise, but it may contain a fast acting nitrogenous fertiliser, so I prefer to use its active ingredient sulphate of iron alone. This needs careful diluting in a watering can, then test a small patch before you water the whole lawn. It can be very strong so care is needed, but it is very effective. I also use it on any mossy path areas. The moss turns black in two days.
Scarifying the surface with a springbok rake will also remove moss and any build up of thatch.
To improve surface drainage use the garden fork to put small holes about two to three inches deep into the surface at about six to nine inch spacings. Then spread on an autumn lawn compost dressing which will have an organic slow acting fertiliser in it  This should have a higher ratio of potassium and phosphates and be low in nitrogen. Brush the compost into the holes.

Preparing for Winter


PREPARING FOR WINTER

Autumn is a very important time in the gardening calendar as it is this time we assess the results of the seasons work so we can plan for the next year. It is also the time to get overwintering outdoor crops tidied up before winter sets in and prepare those requiring winter storage. Then there is the winter digging, fruit tree and bush pruning and before long the leaves will have started to fall.
In fact its quite weird and very unusual, but the seasons seem to be normal. Autumn leaves are falling in autumn instead of early winter, snow is falling at low levels in some places, summer bedding would appear to be finished and the rain has stopped. I cannot remember much wet weather during the tattie picking season, though it was often frosty in the mornings. Then as usual thousands of geese flying in formation overhead are making their way up the Tay estuary. Now, this is autumn.
Allotment work

The cold weather is just what we need to sweeten up the winter cabbage, leeks, kale, Brussel sprouts, swede turnips, Swiss chard and my four parsnips that grew from a whole packet of seeds. Next year I will definitely change the variety and supplier.
Last year I left my beetroot in the ground rather than lift for storage and even though we had a very cold winter they came to no harm, so I will try the same again this year, but earth them up a wee bit to give the roots some protection from frosts.
It is a good idea to try to complete winter digging, adding manure or compost, before the end of the year, but this usually depends on good weather so the soil is not too wet to walk on. Any land sown down to a green manure crop such as mustard must be dug over immediately the first flowers appear otherwise they may set seed and end up being a real nuisance.
Gladioli and chrysanthemums have now finished so they can be lifted and stored for next year. Gladioli are dried off and stored in a cool box in dry sand or dry soil in a frost free shed. Chrysanthemum stools are boxed up and kept moist in a cold but frost free greenhouse over winter.

My strawberry varieties Symphony and Florence have both had three fruiting years, so now is the time to replace them from runners. They have produced a lot of very strong healthy runners so I can afford to give the new strawberry bed on freshly prepared and composted ground special treatment. Rows are spaced three feet apart, but I can afford to make each row a double row six inches apart and space the plants up each row at six inch spacings. This way I will establish a thick row in the first year to give a far heavier crop than traditional planting distances.

Winter Storage

Pumpkins have been lifted, washed and are now stored as an ornamental feature in our utility room where it is not too warm. They will be used fresh for fantastic soups up till next April, then any remaining will have the flesh scooped out and frozen for use later. The seeds will be used for next years crop.
Onions have been dried off and stored in nets hung up in the garage.
Carrots are lifted and stored in between dry straw and covered over with soil to keep them frost free.
Potatoes are now all lifted, dried, sorted out and stored in boxes in a cool but frost free spot.
Apples have now all been harvested, even my Bramleys, sorted out and stored in cardboard trays in the garage. The Discovery variety is finished so now we are eating the Fiesta. Red Falstaff and Red Devil will be stored a bit longer to ripen up.
The freezers are packed with enough fruit and vegetables to keep a large family well fed for well over a year. French beans, broad beans, (it makes a brilliant winter soup) and the best of our sweet corn crop are all frozen and surplus kale leaves get frozen as this makes it easier to break them up for soups without losing any of their nutritional value.
When you add soft fruit to the freezer such as strawberries, rasps, red currants, black currants, gooseberries, saskatoons and brambles it makes sense to pack them in square shaped plastic containers to maximise space and minimise empty air space.
Rhubarb, surplus pears and plums which do not store well can also be frozen to be used throughout the rest of the year.
The latest health trend to use any surplus fruit is in a delicious smoothie. This retains the healthy properties of the fruit or vegetables and can be taken as a food or thick drink. They can also be used in place of cream for summer puddings. Our favourite smoothie at present is made with our Aronia berries. This new berry crop is also called the chokeberry as the fresh fruit is astringent if eaten raw, but easily loses this when cooked. As far as superfood status goes the aronia ranks near the top of the list having ten times as much anti-oxidants as a blueberry. As well as smoothie it makes a great jam and can be juiced for a drink with some sugar added.

Propagation

Geraniums are easily overwintered as rooted cutting taken early in October and put in small pots. Keep them cool and don't over water, but if you wish to build up stock then water and feed oftener and grow in a light warm greenhouse or windowsill. Take the tops out for cuttings as soon as big enough, then take another cutting from the second cutting once it has put on a bit of growth. Grow them fast and repeat the process. It is possible to get ten plants from one plant by late spring.
I will be sowing my Meconopsis, (Himalayan blue poppy) now that it has been in the fridge for three months. It will remain outdoors to complete its stratification period and hopefully germinate in spring.
My saskatoon seed and now Aronia also get stratified before they will germinate. Select good berries at harvest time and squeeze them out of the flesh as soon as possible as the flesh contains germination inhibiting hormones. Wash them and use a kitchen roll to remove the worst of the moisture then store them in moist kitchen roll in the fridge. Do not let them dry out. Sow the seed outdoors in a prepared seedbed or in containers and keep these outside to weather. Germination should occur in spring. However this year my saskatoon variety Smoky has started to germinate. This is October so I do not know if the young seedlings will survive the winter so Smoky will go into my cold greenhouse for a wee bit of protection.

Spring bedding

Now that autumn appears to be with us most of my summer display of bedding plants in beds, tubs and hanging baskets is over. My geraniums are still colourful, so I will leave them alone for another week, and my tuberous begonias still think it is summer. They are still brilliant so no harm will come to them at this stage, even if I have bags of tulips, hyacinths and crocus eager to get planted.
Tubs of begonias will be replaced with a mixture of polyanthus underplanted with scented hyacinths. Smaller pots and hanging baskets will be planted with winter pansies and some crocus, and my main flower beds will be planted with wallflower grown from seed on my allotment, and a mixture of Darwin Hybrid tulips once I finally decide the geraniums are past their best.

Garden Art


GARDEN ART

I often wonder if I have just been lucky, or if fate intended me to have two creative careers.
My horticultural career lasted over thirty years and involved not just growing plants but also using them in the landscape in the design of parks, gardens, housing, highways, retail, industry and forestry.
I got immense pleasure from the creative processes especially returning a few years later when the landscape matured and the improvements could be seen and enjoyed by the public. Some schemes were on a small scale, a shop, a factory, a few flower beds then others were on a more grander scale with ample scope for your creative ideas. A new golf course in Darlington desperately needed trees everywhere, then Livingston new town needing a programme of daffodil planting of over two million bulbs over three years.
All this time I enjoyed a range of hobbies from wine making, swimming, travelling, hill walking and painting.
However, I changed careers in 1992 to become a full time artist and now my horticultural creations are of a more modest scale, such as a hanging basket or plant tub, and my painting has become the source for my creative energies.
Having been blessed, or cursed with the creative gene does bring great pleasure when your work is admired, whether it be a colourful garden, an immense pumpkin or a beautiful painting. The drawback comes when you consider the possibility of retirement. When I officially retire my two main hobbies will be gardening and painting. So, at what point can I tell myself I am retired.

Anyway, coming back from thoughts of retirement, I always seem to find a new project to work on in the art world, and it often starts in the garden or on the allotment.

Allotment Art

A few years back I started growing saskatoon fruit bushes in pots around the house, but soon realised they needed more space to grow, so I decided to find an allotment for them.
It would also serve to grow other fruits, vegetables and flowers getting me back into growing plants again. Then of course there is the exercise value as well as the health benefits of fresh produce all year round.
The new plot needed a fair bit of tidying up to remove old wild brambles, weeds, broken fences and repairing the dilapidated shed. A meandering path in the wrong place needed removing and replacing, so since I have no problem working outdoors in all seasons these tasks kept me on site regularly throughout the winter.
Even when the snow came I couldn't resist a trip to the allotment to see how the plot looked covered in a blanket of snow.
The site was a winter wonderland of untouched pristine snow and as I had my camera with me I walked up and down every path as ideas for winter landscape paintings appeared at every turn. My digital camera was working overtime. City Road allotments have been going for years and now most plots have some kind of shed and greenhouse in every shape possible and in various degrees of hastily repaired dereliction.
Broken down fences, steps, scattered water barrels, pots, boxes, posts, wheelbarrows and old gnarled apple trees covered in snow made perfect subjects for a series of garden winter landscape paintings. One of my neighbours suffering from a bad back recently, had not kept a very tidy plot, but his stack of old boxes, pots, barrels and pallets piled against his semi derelict shed was just perfect. Another plot with an old apple tree pruned way beyond any sensible shape added another perfect image to be captured on canvas.
I enjoyed creating this series so much that I decided to run an allotment painting workshop in the spring.
This turned out to be very popular and at the time there were many plots covered in poppies and other summer flowers. However different people see beauty in different ways. One lady just loved the clever graffiti covering a large shed and for another it was the washing hanging from the tenement clothes lines blowing in the sun.
I also found more inspiration for another series of allotment paintings in both watercolour and acrylic balancing flowers and vegetables against the allotment furniture and structures.

Garden Flowers

Painting the “Winter on the Allotment” series took several months by which time spring had emerged and my garden was a picture of flowers.
This time I decided to throw caution aside and got out some of my biggest canvases. These images were to be very bold using large flowers with impact. My first was the Iceland poppies which brighten up the spring and continue right through the summer as long as you keep taking off the seed heads.
Next was some brilliant candy striped early tulips, Carnaval de Nice contrasting the illuminated blossoms against a deep blue background. A beautiful lemon narcissus was next then my flag iris started to bloom and gave me quite a choice for another large canvas.
I grow a wide range of iris which come in many colours supplied from specialist hardy plant growers in Shropshire, Claire Austin. I chose the deep purple, Dusky Challenger and again used a contrasting pale blue background.
Spring leads into summer and I was overwhelmed with choice of flowers to paint. There was not time to do them all so the camera captured hundreds of images to be stored on my computer so I can pull them out at any time. The digital camera allows you to keep the best and delete the rest.
The apple trees were terrific especially when you zoom in to capture the flowers as a close up, then my bright red oriental poppies gave a fantastic though short lived display.
Rhododendrons and azaleas seem to thrive in this mild wet climate so gave me dazzling blossoms which I like to zoom in on to capture individual flowers or small groups of them.
Another brilliant red tuberous begonia growing in a deep blue flower pot caught my eye. I look forward to getting that one on canvas.
Lilies and fuchsias will always give great value, but you need to photograph them in full sun against a dark background or sometimes I can find a low angle to get them against a deep blue summer sky.

Garden Art Exhibition

John is showing some of his flower paintings at the Dundee Art Society Autumn Exhibition at 17 Roseangle open from Saturday 30th October to Sunday 7th November 2010. Open every day from 11am to 5pm.

Garden Blog

I have created a garden blog to store these weekly articles in, so if you wish to look back to any previous feature they are stored in date order. They can also be viewed by title and keywords. The blog is called the Scottish artist and his garden blogspot.

Saskatoon update

Landward TV will be featuring John's saskatoon fruit bushes on their programme about growing and using Scottish superfoods on Friday 29th October at 7pm on BBC2

Preparing the Soil


GOOD SOIL GROWS GREAT CROPS

We live in times where just about everybody is suffering from some degree of stress. Modern living lifestyles demand a great need to spend money that may be in short supply.
Although past generations may have been a lot poorer and had just as much if not more stress, they were not aware of it. Television and newspapers have made us all aware of how everyone everywhere is living with special emphasis on celebrity lifestyles.
Now we cant all enjoy that life so we look around for activities at our own level to enjoy or for exercise and relaxation.
There is nothing better than going back to nature, with a walk in the hills, or along the seashore, (we have ample places to visit in Scotland) or turning to gardening where you can indulge in growing a few plants around the house or if you are lucky, on your allotment.
They are now in big demand with councils working hard to reduce the ever increasing waiting lists.
Allotment sites are very sociable places where gardening discussions are going on in every corner to swap information and learn how to grow those huge clean vegetables or special brilliant flower displays.
There is a lot of people coming into allotment life with the romantic notion of relaxing on a seat in the sun amidst the wonderful crops of fruit, flowers and vegetables. For some this is reality, but unfortunately for others they never realised that to achieve this euphoric state without recourse to alcohol, a wee bit of work may have to be performed now and then.
It seems a priority to work hard at creating a visual amenity, so paths,fences, sheds, greenhouses, and patios all get attention. However allotment gardening is about growing plants, and these need soil, so this must not be ignored.
Most seed will germinate and grow on any soil without too much effort, but to grow good plants you need good soil, and if you want great plants that will be admired, you will need very fertile soil.
I would advise every newcomer to gardening or allotments to get hold of a book or subscribe to a gardening magazine and study good soil management. There is also excellent websites on the internet that will advise on everything you ever need to know.
Just ask Google.

Soil amelioration

This topic played a major part in studying horticulture during apprenticeship days as it was the custom to buy in manure or make your own compost or leafmould, and use it in all soils at every opportunity.
Every park kept a leafmould heap. Some were quite huge, especially at Camperdown Park and the old quarry in Balgay Park had been filled in with the parks leaves for years.
As the leaves decomposed on the surface they were riddled to remove twigs and debris then the composted leaves used to ameliorate flower beds, rose beds, and shrub borders.
At the nursery riddled leafmould was sterilised and used to make a Dundee version of John Inness compost where it replaced the peat. It may have helped to save the planet, but the geranium cutting did not like it and losses of 50% were accepted as normal. My lesson was complete when I visited a geranium nursery in England where success was 100% and propagators wore white sterile lab jackets. Cutting were snapped off (no knives used) with just one leaf and inserted into a Jiffy 7 pot. I am still doing the same method now as I grow the same four varieties every year overwintering young rooted cuttings.
Flower beds were always manured in autumn to feed the hungry wallflower plants used for spring displays.
Our training involved both fruit and vegetable culture where manuring every autumn/winter was standard practise and our gardener instructor wanted to grow everything to exhibition standard.
Bulky organic manures feed the soil increasing worm activity and soil organisms which break down the manures into humus. This creates a fertile crumb structure which opens up the soil, aerates it and improves the drainage. Humus also darkens the soil which then warms up more efficiently. Where there is a drainage problem or where plants need a deep root run e.g. roses, fruit bushes and trees, sweet peas, it is advisable to double dig those locations forking in manures at the bottom of your trench.

Organic manures

It is not easy to get hold of good farmyard manure today so go for whatever is available such as horse, cow, pig, hen or even seaweed or leafmould. Most will need to be left for six months or longer to rot down before use.
Remember that these mainly feed the soil to create a good structure and fertiliser will still be needed to grow strong healthy plants.

Compost heap

This is where the fertility comes from. I compost everything unless it is diseased , e.g. clubroot or rose black spot or has seed heads such as poppies. Even domestic newspapers, utility bills, bank statements can be shredded and woody material can be chipped and shredded then added to the heap. Grass cuttings, leaves and annual weeds will all rot down.
However discard or dry out any perennial weeds such as couch grass, mares tail, nettles, willow herb, dockens or dandelion.
Keep the heap for nine months and try to turn it over at least once. Keep it moist to assist worms and organisms, but also keep it covered to retain the moisture and warmth. A good compost heap can kill seeds and weeds during decomposition heat up.

Discovery compost

Dundee council make an excellent very black compost from domestic green waste. This is well rotted and weed free. It is great for adding to soils to dig in or mulch or even added in small quantities to potting composts. It is heavy to handle but for £0.50 per bag of any size it is great value for money.

Green Manuring

This is an excellent method of improving soil fertility. When the early crops such as broad beans, early potatoes, sweet corn, dwarf french beans or even old strawberry plots are finished, dig or fork over the ground, add some fertiliser then scatter some mustard. You can also use annual rye grass, tares, or clover. Dont use mustard where clubroot is a problem as it will hold onto that fungus.
As soon as the first flowers appear, trample down the stems and dig it in before it gets a chance to set any seeds.

Rotation

Now you have all this lovely compost decide where best to put it. Use the rotation principle where you grow all the heavy feeders together, i.e onions, leeks, beans, courgettes and pumpkins get the lions share, but keep some for the brassicas.
Root crops are happy to grow on soil that was manured for a previous crop, though I still keep some for the tattie patch. Fruit crops do not need any unless used for a mulch, or before planting to get them established.

Planting Spring Bulbs


PLANT SPRING BULBS NOW

It is always very uplifting to see the emergence of the first spring flowers after a long dark cold winter. They are the sign that winter is ending and warmer weather is on its way.
Traditionally March was the turning point when shoots started to appear, then up popped the first snowdrops and winter aconites. Global warming has changed all that, but climate change is not occurring gradually. It is a bit like the stock market, over time it improves but has wild swings along the journey. Several years ago I was enjoying a coffee break outdoors in glorious warm sunshine at the end of February. Last April my early tulips were broken down with the weight of snow on them. I used to think Narcissus February Gold was a joke as it flowered in April, but now it almost does flower at the end of February. See the drifts of them along the Lochee Road next February or maybe March.

This is the time of year to be planning, buying and planting bulbs for that early flower display. The garden Centres, nurseries and stores are full of bulbs for every situation around the garden.

Bulb planting ideas

Bulbs start to flower in February with the snowdrops and continue till mid summer with the lilies. They will give a more impressive display if they are planted in bold drifts. They can also be mixed together with several types of bulbs to extend the season of display. Snowdrops can be mixed with crocus and tulips which are planted deeper and also summer lilies which flower much later, but all grow happy together.
However consider the location for each type. Snowdrops, aconites, bluebells, chionodoxa and grape hyacinths are all happy in partial or dappled shade, whereas crocus need sunshine to open up the flowers. Many bulbs thrive under deciduous trees as they do their growing early before the trees develop a dense canopy. Often this canopy will dry out the soil surface in summer which may suit the bulb during its dormant stage.

I find numerous places to grow bulbs in association with other plants such as in the herbaceous border, coloured stemmed or winter border, woodland border amongst the Himalayan blue poppies, and of course in the spring bedding displays in borders and tubs.
Bulbs, such as hyacinths and narcissus can also be grown in pots for the house, then later after flowering dried off and planted out in the garden.

Early flowering bulbs such as narcissus and crocus can be planted in lawns, but remember to let the leaves grow to feed the bulbs for the following years flowers. Always allow a minimum of six weeks from flowering before mowing off the leaves, though many people will advise to leave them till they begin to turn yellow. In some wet years that can take a long time especially with the large headed daffodils.
Another great plant association is a drift of Anemone blanda with Cyclamen hederifolium as they both have totally different flowering and growing seasons. Anemone blanda flowers in spring, then grows quickly till mid summer before dying down. The cyclamen flowers emerge in late August to September and continue to grow till winter before dying down.

To capture and enjoy the beauty of those first flowers in late winter plant some snowdrops, aconites and crocus species in view of the main house windows. Then even after a snowfall you can still see them emerging unscathed from the comfort of a warm house. I have a drift of these next to a beautiful pure white Christmas rose, Helleborus niger which flowers at the same time and viewed from the patio window.

Bulbs for the house

Hyacinths are hard to beat for a flowering scented house plant and come in many colours. My favourite was always the red Jan Bos, but there are excellent blues, pinks and whites. For the earliest flowers choose bulbs that have been prepared for forcing and try to get them potted up at the end of August or early September.
Bulbs can be planted close together, even one above the other in bulb fibre compost in wide pots. Water them in then put them outdoors against a north wall. They prefer to be kept dark at this stage for about ten or so weeks and protect them from frost and mice.. This encourages root growth but holds back leaves and flowers. They should not need much watering. Keep checking them for signs of shoot growth and as soon as they begin to grow, probably in late November to December, introduce them to a light but not sunny place such as a cold frame or cool greenhouse. Keep them cold but frost free, until the flowers begin to show. Gradually warm them up but leave it to the last minute before you take them into the warmth of a house otherwise they will grow too tall.
Early narcissus and dwarf tulips e.g. Red Riding Hood, can also be grown in pots for early flowering. I like the scented Cheerfulness types which have double flowers and a heady perfume. Grow them the same way as hyacinths.

Bulbs for the garden

My season starts in early February with a clump of snowdrops planted under my grape vine on a south facing wall which gets a lot of heat from the sun. Then other snowdrops, aconites and crocus species all come together. Crocus should come after the snowdrops, but not any more. Anemone blanda is drifted under our apple trees and follows the crocus before the bluebells smother the ground under our Bramley apple and Victoria plum, all happy to grow together. In the front of our fruit tree mini orchard, (five trees) there are drifts of lilies which grow up into the sun.
The herbaceous border is covered in hyacinths previously grown in pots but now naturalised plus Chionodoxa, the Glory of the Snows. One display after another.

Where ever there is a space amongst shrubs I have planted sacks of daffodils, narcissus, tulips and grape hyacinths which are all left to grow and spread as they wish. I keep adding to them every year. Types of fosteriana tulips have large flowers, are very early and naturalise well.

Tubs and Beds

My Parks Dept training as a gardener was very thorough so I always follow our tradition of planting both summer and winter bedding plants in borders, tubs and hanging baskets.
At this time of year the normal selection will be Wallflowers, Myosotis, Polyanthus and winter flowering pansies.
I choose the tall Darwin Hybrid tulips for interplanting amongst the wallflower, but dwarf early tulips or species to go between the others.
Tubs and pots are also planted with dwarf tulips amongst the pansies and myosotis and often a few crocus are added to give an early display.
I do not use bulbs in my winter hanging baskets as these are usually filled with winter pansies which can suffer from too much foliage from the crocus which just loves to grow when you water and feed them.
All of these bulbs get dried out after flowering to be reused elsewhere in the garden the following year.

Tayside Top Fruit


TAYSIDE TOP FRUIT

Very few pleasures in the garden can match the delight in late summer of picking that first bright red apple from your own home grown tree. Very few adults let alone children can resist the temptation to pick an apple once it has turned ripe. Nothing from any supermarket can touch the home grown apple for taste.
They are not difficult to grow once you have a grasp of some basics practises.
Apples are the starting point and once you have your first crop harvested, (usually about three apples) you are now ready to take on the next top fruit tree on the list. This will either be a plum or pear, and once they start to crop why not accept global warming will happen and try those more exotic fruits previously only grown in warmer locations.
Lets look out an early variety of cherry and peach tree.
It is always a good move to do a wee bit of background research to find out where it all started, how top fruit growing has developed over the years and how that affects us today.

History and culture

Apples have been grown in Scotland for hundreds of years. They were an important food source in monasteries or private estates, then more recently, grown commercially to supply local markets. Every area would have its own varieties peculiar to its needs and history.
However the world today is a very different place and top fruit culture has seen massive changes. People now prefer to shop at supermarkets and they demand a product that looks good, has a long shelf life, is cheap to produce, handles and travels well, and is evenly sized with a blemish free skin. Growers in turn require a variety with a heavy yield producing apples that don't bruise when bulk handled and can resist or tolerate the majority of pests and diseases..
In the past apple trees were sprayed with chemicals every ten days throughout the whole growing period, but this is now frowned upon, so they prefer to grow strong vigorous varieties resistant to scab, mildew and canker.
To keep costs down the trees are grafted onto dwarfing rootstocks and the apples grown on a hedge row system so all pruning and picking can be done from the ground. It is too slow and costly to send pickers up ladders to harvest the fruit.
Thus today, there is a very limited range of varieties grown commercially as few of our older heritage range would pass the stringent criteria demanded by the supermarkets. Unfortunately good flavour does not seem to be a high priority.

Plums and pears were also once a major crop in Scotland, but economics has wiped them out commercially.
Life however, moves on and there could be a return on a smaller scale to some of our older varieties grown to supply local farmers markets as demand increases for quality fruit with flavour and ripened on the tree before harvesting.
Many older fruit varieties are being found in old derelict orchards and are now being propagated and promoted as interest grows in our past history.
The Bloody Ploughman, Scotch Dumpling, and Tower of Glamis may yet emerge from the mists of time, and my Arbroath Pippin, also known as the Oslin, may be very old and non commercial but is hard to beat for a very early apple.
For the home gardener this is the time of year to be looking out the wide range of varieties in nurseries and garden centres while many have fruit on the young trees and selecting those you wish to try out.

For more information on our heritage fruits visit the Carse of Gowrie Orchard Festival starting at Glendoick Garden Centre on Saturday 9th October and Sunday 10th then continuing all week to Sunday 17th October with events all over the Carse of Gowrie.

Apples

If you only have room for one tree then go for an apple. They come in all shapes to suit every ones needs. You can have a bush, tree, espalier, fan, low step over form or even a slender minarette. They also come with one, two or even three different varieties all on the same tree.
In a later article I will cover grafting so you can learn how to add additional varieties to your tree or even rejuvenate an old tree. There is no limit on how many varieties you can have on one tree. My James Grieve apple has now been grafted with Discovery, Red Devil and the Oslin and I will add a few more varieties next April. I am afraid I was just not impressed with James Grieve, though it is still very popular.
Other good varieties for Tayside are Scrumptious, Katy, Red Falstaff and Fiesta. However the latter has a tendency towards biennial bearing.
The best cooking apple has to be Bramley as it is very prolific, has huge apples, is quite disease resistant and the fruit store for a long time.

Plums

My favourite has to be Victoria which crops well and has a fantastic flavour. It freezes well and ends up in jams, stewed for a mixed compote and crumbles. It is very reliable. I assist pollination with a Berberis darwinnii planted below it. It's bright orange flowers come out at the same time as the plum and attract the bees who cannot resist it.

Pears

In the past I would have said a Comice and Conference combination would be best for good cross pollination and when we get a good summer Comice is outstanding. However as the last four years have been very wet my Comice has suffered badly from scab and the crop has been lost. Conference resists scab but is not as good as Comice.
I will be looking out for a better variety to graft over some of my Comice branches early next year. Pear trees can grow quite big so if space is limited go for a minarette, cordon or espalier trained tree.
Scab in a tree is hard to control as there is very few chemicals available now and anyway a large tree is hard to spray.

Peaches

I grow Peregrine on a south facing tall fence and now that I have peach leaf curl under control I am getting a decent crop. The fruit is quite large, well coloured, very juicy and sweet. As my small tree is fan trained, the pruning, which can be quite complicated at first, has to be carried out thoroughly. This allows light into the tree, restricts excessive growth and ripens up young shoots which will replace this summers fruiting wood.
I control peach leaf curl with two sprays of Dithane at leaf fall and just before bud burst.

Cherries

I will try out a bush sized trees grafted on the very dwarfing Gisela 5 rootstock so I can net the tree for birds. My favourite at the moment is the self fertile Cherokee, but by winter I may change my mind after a wee bit more research.

Planning a new garden


PLANNING A NEW GARDEN

We all face this situation each time we move house, whether just married, moving up the property ladder or moving to a new location following the sun.
It may be a new house where the builders have just left, it may be flat but turfed, or it might be an existing home where the previous owner has left behind his neglected, overgrown or fantastically landscaped garden. However, you are likely to want to develop your own ideas for your garden, but just where do you start!
I have always loved gardening and my horticultural career has taken me all around the UK, so every time I found a new house it had to be landscaped to my needs at that time. I always had a notion of the plants I wanted to grow if room and funds permitted. In the early years the house and garden were quite modest and there was always a garden problem to solve. Nothing much has changed except that my garden is a wee bit bigger and I have now grown many of those special must have plants.
The experience of creating new gardens has developed into a pattern that can now be followed breaking it down into logical stages.
Let us start at the beginning.

Site analysis

I always start here, walking over the site and noting if there are any worthwhile features, e.g. specimen trees or shrubs, or good views to preserve, eyesores to remove or problems, e.g. steep slope to solve. Now look over the fence and see if any screening is needed for neighbours washing line, adjacent busy roads, building next door with windows looking onto your private patio.
Have a look at the topsoil, dig a few pits a foot deep. Is it good, does it need amelioration, assess the drainage to see if this is a problem. Look at local weeds. Nettles indicate good soil, buttercups, wild orchids and reeds wet soil.
You will now be getting an idea of the site's potential, so you can incorporate your own needs. Give every idea an airing. Will the garden be totally ornamental or will you want a vegetable patch, and what about some healthy fruit crops. Will you plan for a compost heap. This was always an essential with me where I recycle all plant waste material including tree and shrub pruning after shredding them, plus all household waste paper that goes through a paper shredder first. However don't compost any diseased material.
What about a greenhouse and shed for pots, canes, tools, wheelbarrow and wood shredder.
Getting friends around for the barbecue on those long warm summer evenings and a patio in a sunny sheltered location is needed to relax on after all this garden planning. Very mentally exhausting work.
Then of course there is the lawn, for some an absolute essential, and for others nothing but a problem area that is always full of moss and weeds and never stops growing.

The other major task is the hard landscaping of paths, walls if required, rock garden for some, fences, and services (water and electricity) to the greenhouse and shed.

Finally what about all those plants you want to grow for year round interest and colour.
Now the work can begin!

Structure, shelter and privacy

A garden will take on a very professional look if it has a good structure within which specific features are incorporated. Start with selection of trees. Is the garden big enough for one, two or more? Trees come in all shapes and sizes so nearly every garden can take at least one of a modest size. I will tackle this subject in a later article showing a wide range of trees suited to the small to medium sized garden.. The small garden can consider some slow growing conifers, an upright cherry, Prunus amanogawa, or hornbeam, Carpinus betulus pyrimidalis and if your drainage is good what about the golden Robinia frisia.
Keep trees, especially willow and poplar, well away from house walls and check where the services are before you drive in any supporting tree stakes.
Shrubs are the next item to be planned, usually to define boundaries or give shelter and privacy. However the planning of these will depend on the location and route of paths, greenhouse, sheds, vegetable patch and patio. Many shrubs flower and some such as the Philadelphus are scented.
I like to blend buildings into the garden landscape by using climbers on any bare wall around the house and on surrounding perimeter fences. Choose plants known to do well on the appropriate wall face, as some need the warmth of a south wall and others prefer a north wall, (more information in a later article).

Entertainment and Relaxation

The patio and barbecue should be big enough to accommodate several people. It should be sheltered, have privacy and will be hard surfaced. Outdoor tables and chairs will be needed and it is a good idea to have some colourful bedding plants in tubs, hanging baskets and borders to brighten up the area. Scented plants located nearby add to the tranquillity.

The lawn

Decide whether the lawn is to be attractive but functional with daisies and buttercups cut with a rotary mower or whether it is to be a feature of admiration with level surface, close mown weed free fine grass which the cylinder mower leaves in pretty stripes after its weekly cut. Of course, the edges will need to be kept cut regularly. The height of the lawn must relate to any surrounding manholes and path edges so the blades do not get chipped and make sure there is free access to get onto the lawn. Plan the lawn shape with flowing perimeter curves so mowing is easy. Select an appropriate grass seed mixture depending on what type of lawn you wish. Do not use a fine grass mixture if the kids will be playing ball games or riding bikes over it.
The greenhouse

If you like to eat very fresh salads, home grown sweet cherry and the larger Alicante tomatoes cannot be beaten when picked totally ripe off your own plants.
Then you can also grow a grape vine and any amount of bedding plants.
Site your greenhouse in a sunny but sheltered spot and put in power and water before you dig foundations. I have always put in a brick base about a foot high to give extra height for my grape vine and giving added drainage with a large pit dug out and filled with old crushed bricks. Top up with 6 to 9 inches of good topsoil. Grapes want decent soil to get them started, but then good drainage. Don't feed or over water them much once established.

Colour all year round

There is a huge selection of excellent flowering plants to brighten up every month from early spring to summer bulbs, spring and summer bedding plants, herbaceous and border plants, flowering trees and shrubs, lilies, gladioli, carnations, bush and shrub roses and annuals for a quick display. The effects will change continuously as every time you visit a nursery or garden centre you will always find something new to try.
