Autumb bulb planting

AUTUMN BULB PLANTING     

As the long hot summer becomes a distant memory, (well, you have to dream a wee bit) and temperatures begin to drop, the first signs of autumn appear as maples and birch trees begin to colour up. Instead of contemplating the onset of yet another serious winter, we leap ahead to next spring as we anticipate the garden in all its glory as the spring bulbs we are about to plant come into flower. It is the masses of spring flowers starting with the snowdrops and aconites then one type after another as the days warm up that keeps our spirits and hopes high. This year will be the good one and maybe we will get more than just four continuous days of really good weather.
I will have to rely on my bulb planting for my main spring displays as the wallflowers are very poor this year and my Forget me nots, Myosotis, got devoured by slugs at the seedling stage.
The garden is already packed with bulbs, but there is always room for a few more, or to replace losses. The mice have been digging up my snowdrops and crocus, and the daffodils are getting eaten away with narcissus fly maggots.
Bulbs can be planted underneath deciduous shrubs, in flower beds, tubs, window boxes, in between herbaceous border plants, and rock gardens. They can also be grown in pots, some forced to flower early for displays in the house, then once they have finished, planted in the garden to flower another day.

Flower beds and tubs

Spring flowering wallflowers, pansies, polyanthus, myosotis and daisies are always enhanced when interplanted with suitable bulbs. The bulbs need to flower at the same time as the bedding plants and grow to the right height. Tulips are the favourite, though hyacinths are also perfect in tubs, window boxes and beds close to entrances and windows where their perfume can be enjoyed.
Choose tulips carefully with the taller Darwin hybrids eg. Apeldoorn, for wallflower, but use single early types, eg. Bellona or Couleur Cardinal, or dwarf doubles eg. Peach Blossom, Carnaval De Nice or Red Riding Hood with low growing bedding plants such as pansies or polyanthus.
The Fosteriana group are quite early and Red Emperor and Purissima are large headed and very showy.
Many other types such as the triumphs, lily flowered, parrot, fringed, and paeony are very attractive but may be too late to go with bedding plants. These are perfect on their own in borders.
Crocus hybrids can be used in tubs and borders with low growing spring bedding, but will provide a display before the bedding plants flower. After they flower, if the leaves begin to obscure the bedding they can be removed and replanted elsewhere in the garden.

Borders

There is bulbs suited to every situation from rock garden to shrub border, sun to shade and some like it dry and others happy in a bog garden.
I tend to go by the season then plant each type in the most suitable location.
The first bulbs to flower are my snowdrops then aconites. These may come in early February in a mild winter. At that time of year it is nice to view the garden from the warm comfort of the house, so I like to have these bulbs planted in front of my patio window so I can enjoy them when I take a break from the easel or the computer chair.


Snowdrops are very accommodating and are happy in full sun or shade. They are excellent in deciduous woodland where they can flower, then grow, mature and die down for the summer as the woodland canopy closes in. It is best to divide and split up overcrowded drifts immediately after flowering as they transplant readily at a time of year when there is plenty moisture in the ground.
Crocus can also be planted under trees, but need sun to open up the flowers. The crocus species tend to be about a week earlier and have smaller flowers, but they naturalise easily and soon form large impressive drifts. Cream Beauty and Blue Pearl are my two favourites.
Narcissus February Gold usually flowers in March in Dundee unless we get a very mild winter, Then other narcissi have their show before the large trumpet Golden Harvest, King Alfred, and Ice Follies have their display. These taller bold flowers will mix well with the Fosteriana type of Tulip such as Red Emperor which flowers at the same time and is a similar height.
Blue is very popular in spring with Anemone blanda, the grape hyacinth Muscari and the bluebells as well as the Chionodoxa, commonly known as Glory of the Snows.
Most spring flowering bulbs start to grow after flowering then die down to have a period of dormancy over the summer months. However there is always a few that buck the trend.
Autumn crocus, also called Naked Ladies as it flowers in September and October when there are no leaves around, is really a Colchicum and quite a different plant family from the crocus. Although a very attractive garden plant be very careful as every part of it is extremely poisonous. Many deaths have occurred when people have mistaken the bulbs for garlic and used them for cooking.
Some crocus species do however flower in autumn and the most significant one is crocus sativus grown for the production of saffron using the gold coloured flower stigmas.

Cultivation

Most bulbs are not too fussy with soil as long as it does not suffer water logging. I give my drifts in shrub borders a thin mulch of well rotted compost in autumn then let the winter rains and worms mix it into the surface. You are unable to cultivate deeply as most bulbs are near the surface.
After flowering collect and spread any seed as this will grow and help the drifts to naturalise.

Forcing bulbs

The flowering season can be brought forward with hyacinths, daffodils, tulips and crocus by planting them in pots in September, keeping them in a cool dark place for about ten weeks or so then slowly introducing them to the light. Once they start to green up and grow keep them cool but frost free and only give them some warmth just before flowering when they are then ready to be brought indoors. Best keep the mid day sun off them or they may go over too quickly.

Try a taste of the Exotic


TRY AN EXOTIC FRUIT     

The Scottish climate is very favourable for growing a wide range of both soft and top fruit but this range can be extended if we have the benefit of a south facing wall in a sheltered location. We all love a challenge, and trying to get a crop from a plant everybody knows needs a warm sunny climate really tests your gardening skills. We have heard so much about climate change and global warming that we begin to believe that the weather might just warm up and we can then contemplate growing those plants usually confined to the south of the country.
A few years ago I started trying out a range of different grapes on my allotment to see if our climate has now warmed up sufficiently to find a good cropping grape. The allotment plot has great soil, a south facing slope and excellent drainage. I have cultivated it quite deeply over the years and added plenty of manure and compost. What could possibly go wrong.
All the grapes grew vigorously, though training and pruning kept them under control, but where are all the grapes. Maybe I have not yet found the right variety, though more likely this global warming is just a political myth, or it has not yet reached Scotland. The climate has certainly changed. It is more predictable than ever and extremes seem to be normal. We did get a heatwave a few years ago but what about this year. It will be remembered for the long cold severe winter followed by severe spring gales, thunder storms and a cool wet summer with very little sun.
However, we shall continue to experiment with the more exotic fruits just in case climate change brings in a wee bit warmer weather once in a while. Last year I got over forty figs and a dozen peaches. That made all the work and effort well worthwhile.
I can take advantage of warm south facing walls and fences around our house which sits on a south facing slope, but unfortunately we do not have shelter being exposed to the prevailing winds.

Grapes

My first range of grape varieties were just not suited for growing this far north, but I am now trying out one called Solaris recommended for more northerly locations. This time it has the benefit of a south facing fence. The ornamental variety Brant grows and fruits extremely well on my south facing house wall. It produces about 100 small bunches of black sweet juicy grapes in early September. It is the success of this one that makes me feel they will work if I can get the right variety.

Figs

I first tasted a Scottish grown fig about forty years ago. A farmer friend near Montrose grew them in his garden and was delighted to be able to offer me these exotic fruits. I had never tasted a fully ripe fresh fig just picked from the bush. It was absolutely delicious, so I have had a fig tree in the garden ever since.
They are very easy to grow, and normally quite hardy though last winter put that to the test. They suffered a fair bit of die back in spring with a loss of most of the fruit buds. However growth soon resumed with great vigour, though this year I am down to a handful of fruits.
Brown Turkey is still the best variety and growth needs to be restricted by growing them in a slab lined pit about three feet square with plenty of brick rubble in the bottom for drainage. I train mine on a south facing wall to give them the warmth to ripen up the fruits. Watch them very carefully as they ripen as in our wetter climate botrytis can be a problem when you leave the fruit to ripen to its deep purple brown colour.


Peaches

Another fruit that needs the warmth of a south facing fence or wall. My peach Peregrine is very hardy and growth was unaffected by last winter. In fact the long winter was a distinct advantage since flowers did not appear till quite late when danger of frosts had passed. However there was a distinct lack of pollinating insects so my sable brush was used daily to help pollination. The flowers did not look very strong and cool conditions did not help fertilisation, so one by one the flowers failed to set and fell off, apart from one. It will not take very long to bring in this year’s harvest.
However this will give me more time to concentrate on my other life as the artist as I am now enrolling for my autumn session of evening art classes.

Cape Gooseberry

This fruit from Peru is grown as an annual from seed and often with the protection of a glasshouse. Some people have had success in growing it as a perennial cutting it back to the crown in winter. Glasshouse space is often at a premium with grapes, tomatoes, and cucumbers so I grow mine in the shelter of a south facing fence. The soil is deep, rich and well drained so plants can grow quite vigorously. I let them branch as a wide bush so they do not need staking or pruning. The fruit may not ripen up till well into the autumn, but be patient as when the Chinese lanterns produce their orange berries the wait will have been well worth it. Make sure you get the type Physalis edulis as it has the biggest berries.

Goji berries

This new fruit grows in Tibet, China and Mongolia and is related to the potato. It is a vigorous bush growing up to eight feet tall and may fruit in its third year. The orange red fruit are very high in vitamins, minerals and anti-oxidants. This has been used in their promotion as a superfood, but is largely unsubstantiated by scientific research. The ripe fruit must be harvested very carefully to avoid damage to the fruit which is then dried in the sun like a sultana.
My climbing bushes have not yet fruited, like so many others who are trying them, but one gardener did get a crop from them. Unfortunately it was not to his liking so the bush got dug out.
Maybe next year I will get the chance to put them to the test.

Kiwi fruit

This will only grow successfully outdoors in this area in a very sheltered warm position. They are quite vigorous and some varieties come as separate male and female plants, though there are now varieties such as Jenny that are self fertile. Keep growth under control by pruning similar to grapes.

Late Summer Harvest


LATE SUMMER HARVEST     

September must be a very healthy month. Fresh vegetables and fruit are at their peak. There is such a huge range available that you should be able to reach your five a day needs by lunch time and a few extras at teatime as the bonus.
If you managed to catch the sun when it appeared briefly last month you might just have a wee tan, and the garden is providing some gentle exercise, removing the last of the weeds, a bit of pruning and the harvest tasks.
As the harvest is gathered there will be plenty of waste for the compost heap. However any diseased leaves (blackspot, rust, mildew), or roots (clubroot) should not be composted, though I still use mine. I grow my sweet peas along a fence in the same place every year and build up the fertility with compost as they are gross feeders. They also appreciate a deep fertile soil that is well drained, so in late autumn I open up a deep trench, put all my diseased plant material in it and turn it over. Sweet peas are in a different group from roses and brassicas so will not be affected by these problems, but remember the disease spores can travel down a slope in the winter rains so consider where you site your sweet peas.

Onions grow best in very fertile well drained soil and need plenty of 
sunshine to grow and ripen, so this should not be a good year for them as there has been a distinct lack of sun and an awful lot more rain than we need. Yet my onions have never been better. I put this success down to good soil and the right choice of variety. One £2 packet of seed of onion Hytech gave me a crop of 150 large round onions that are reputed to store well. They are now lifted and will be dried out in the sun. When the foliage has gone brown I will rope them for easy storing hanging up in the garage.

Sweet corn is another crop that needs warmth. Normally I would get about seventy cobs from sixty plants grown from one packet of seed. I got the excellent plants, but just as soon as they got growing the gales came. They have never really recovered. Growth is reasonable but the plants are totally disorientated. Only a few male flowers appeared at the same time as the female silky tassels grew from the top of the cobs. Other male flowers appeared two weeks later by which time the female tassels had withered, so pollination was very patchy and I will only get about a dozen decent cobs. There will be nothing for the freezer.

Beetroot germinated and grew very quickly. Thinnings were removed as young baby beet, but those remaining have not grown into the normal larger sized beet. It seems this will be the year for baby beet. Last year I left my main crops of large beetroot in the ground where the early snowfall provided a cold blanket which protected them from hard frosts. They kept perfectly till the end of February.
Beetroot is a very healthy vegetable which we use a lot of to make soup and eat fresh in salads after boiling and dressing in a sauce made from soya sauce, balsamic vinegar, honey and seasoning.

Beans have had a mixed year. Broad beans were good, but I chose a dwarf variety, The Sutton which did not crop very heavily. However I have sown another late batch, now in flower so I hope to get two crops this year. It makes a heavenly soup. French and runner beans have been slow to grow and cropping has been light. There has not been the usual heavy crops for the freezer.

Courgettes and pumpkins both suffered from the gales but are now growing strongly. They have lost too much time and with a poor summer the harvest will not need a wheelbarrow to cart them off the allotment. My winter soups will be well rationed, but they both brilliant.
However many other allotment holders who had kept their plants protected under glass till after the gales have had fantastic crops. Next year I will not be so early to get them planted.

Swiss chard has again grown very well this year and the variety Bright Lights has a wide range of attractive colours with red, yellow pink, white as well as green stems. This leafy vegetable is very high in vitamins and minerals, dietary fibre and proteins. It is used in stir fries, salads when very young and soups.

Healthy fruit has been in abundance this year, with most now either consumed fresh or in the freezer. Autumn Bliss raspberry is very late and I am still waiting for my first serious picking.
My new perpetual strawberry, Malling Opal has been a huge disappointment. A row of ten plants only produced one runner. The fruit is hard, ripens unevenly, has no great flavour, and it is not a heavy cropper. It is supposed to crop till the end of October, but unless we get a late summer the fruit is hardly worth picking. This variety was bred in Kent so maybe it is just not suitable for Scottish conditions.
Blueberries lost a lot of foliage in the gales so the fruit is smaller than normal, but the crop is still quite heavy. These berries are similar to my saskatoons but it is a real advantage having them in fruit when the Saskatoon picking has finished.
The chokeberries, Aronia melanocarpa Viking is now in full cropping. Some will be used for jam, some for compote and summer puddings and a batch for making a strong red dessert wine. Hopefully this will be at its best in three years, but I will need to sample some round about Christmas just to make sure it is maturing ok. The fruit is a bit astringent so is not normally eaten fresh, but can be juiced or processed into many products. The very dark fruits are quite high in vitamin C and it has one of the highest levels recorded of the antioxidant anthocyanin.
Hopefully my wine will be a true health giving tonic.
Rhubarb may have got hammered by the gales as the large leaves were a sitting target, so there was no early crops, but they soon recovered and have been growing very strongly. We are now taking off our final picking for the freezer, so the plants can build up a healthy crown to see them over winter. As well as rhubarb crumble and pie it makes a lovely jam if mixed with dried figs.

Winter crops will provide the fresh vegetables right through the winter so will not need to be stored or frozen. Leeks, swedes, cabbage, cauliflower, kale and Brussels sprouts are all putting on good growth, though some have been attacked by caterpillars, pigeons, rootfly maggots and clubroot. You do not get your green healthy winter vegetables easy.

Cut Flowers


GROW YOUR OWN CUT FLOWERS    

 I love to see an attractive garden with a show of flowers in some part in every month of the year. This is quite possible with a wee bit of knowledge of plants and some careful planning. However the garden is part of the home so many of the flowers end up in a vase, table decoration or grown in a pot for a colourful windowsill.
This is where I am often very unpopular as many people feel that flowers are for picking. They certainly do brighten up the home, but at the expense of my outdoor displays, so I have always set aside a part of my garden or allotment specifically to grow cut flower for the house. This saves the loss to my outdoor flower beds.
The range of plants suitable for cut flowers is immense and can cover every month in the year. Suitable flowers can be tall like gladioli for a bold impressive vase or small like pansies for a table decoration in a small bowl using oasis to keep them moist. The vase or bowl is often enhanced with some greenery using foliage from plants not necessarily linked to the cut flower.

Flowers by the season

Spring belongs to the flowering bulbs of daffodils, narcissus, tulips and iris.
In summer there is plenty to choose from with roses, carnations, gladioli, sweet peas, dahlias, lilies and chrysanthemums.
Autumn cut flowers include the later chrysanthemums that may need some protection, Michaelmas daisies, and again roses that just keep flowering if they can get a bit of warm sunshine.
In winter we might begin to struggle a bit for a wide range, but shrubs such as Viburnum fragrans can help us out for table decorations, and some plants such as perpetual carnations given some greenhouse conditions will fill the gap. A good table decoration for Christmas can be made with a few red carnations in oasis surrounded with yellow jasmine. Freesias are very welcome in winter, but need a glasshouse for protection. Late blooming chrysanthemums can be grown in pots or wire baskets outdoors then brought inside under glass to complete their flowering up till Christmas.

Herbaceous and annuals

Many herbaceous plants are tall and strong and will last well when used for cut flower. Flag iris are my favourite as the flowers are bright, bold and scented. Pyrethrum and Doronicums are for the early season and phlox, Japanese anemone and michaelmas daisies for late summer.
Good annual plants grown from seeds include snapdragons, larkspur, helichrysum, cornflower, sweet William and the scented stocks.

Bulbs and corms

Daffodils, narcissus and tulips can usually be found a spot out of the way under some shrubs or even under a fruiting bramble. Their seasons work well together. I grow my alliums and lilies under the shrubs of my coloured stemmed winter border and my Azalea beds where they all live in a happy association.
Many Daffodil and tulip bulbs start off in pots in late summer to be forced outdoors then brought under glass to complete their flowering. If the pots are small they are fine indoors, but sometimes the flowers are cut if the pots are too big.
Freesias can either be used as pot grown or cut flower started as seed or small bulbs. They will need a glasshouse but the blooms make excellent cut flowers with a heady scent.

Favourites

Roses have a long season with National Trust a deep red with perfectly formed heads, but unfortunately no scent. Ingrid Bergman, another red, is vigorous, produces many flowers and is scented. Margaret Merril is a white with pink blush and scented, as is Pure Bliss a pale pink rose. Golden Celebration is a good yellow strong grower with scent. 
Chrysanthemums have a wide range of colours available and may be grown as sprays or as single blooms on a stem. Sprays are easy to grow and require no disbudding, but decorative, incurves and reflex blooms need summer disbudding to leave the centre bud to develop into a large flower. I grow mine in a two foot wide bed and support the flowers with six inch mesh fencing wire held firm between four posts. As the plants grow the wire is raised up the end posts. You can plant out the bed as one plant in each six inch square mesh and grow the flower on one stem
without stopping the main shoot. This will make it flower earlier than one which is stopped and branched.
Carnations
are long lasting and many have a deep clove scent. Grow them in a bed or single row and support the flowers with canes. Border carnations and pinks are grown outdoors for summer flowering, but perpetual flowering carnations can be flowered all year round in a glasshouse.
Dahlias
are excellent as a cut flower but take up a lot of space. If you grow them for a garden display there is usually plenty of flowers for a good show and cut flowers. There is a wide range of colours and types though

decoratives and cactus are best for cut flower.
Gladioli
are great value and very easy to grow. I add a few new colours every year, but save the corms from year to year. After autumn cleaning of lifted corms I select out all the biggest bulbils and sow them in a broad row to grow into new corms. Many flower in their second year.
Sweet Peas
are very versatile. They can be grown up a six foot net, on a tall fence or traditionally in a double row supported with six foot canes. For a garden display they are best grown from seed in autumn or early spring, tipped after two to four leaves then after planting out left to grow unchecked. For larger blooms for cut flower grow then on a single stem tied to a cane and pinch out all tendrils and sideshoots. Sweet peas grow best a well prepared double dug trench, manured in both spits. Give a dressing of fertiliser before planting and more feeding in mid summer.
Always cut off all seed pods as they sap the strength of the plant at the expense of flowers.

A bed of Roses


 A BED OF ROSES    

If your garden was very small and you could only grow a few plants, there is a good chance that a rose would be selected. They have perfect flowers, scent, are easy to grow with a wee bit of knowledge and can last for years.
Last February I covered some basic thoughts on roses as a pleasant way to brighten up the long cold winter.
Previous articles can be seen on my gardening blog at scottishartistandhisgarden.blogspot.com
We are now in mid summer, according to the calendar I believe, and the roses are back in full flower again for the second flush. The first flush had a lot of promise and was quite brilliant for a week or so, but it is hard to put on a fantastic show in a Scottish monsoon.
It certainly sorts out the favourites, and tests their ability to survive blackspot.
I have been fairly ruthless in grubbing out anything that is prone to disease, though it is hard to lose some of your favourites. Margaret Merril is a gorgeous white with terrific scent, but does get a bit of blackspot. She is too good to lose so I resort to some chemical spraying, (Systhane containing Myclobutanil) whenever there is a couple of dry days in between showers.

Types of roses

Demand for roses has kept the breeders busy for years. We now have every colour we need and a rose for every situation. They can be planted in beds as bushes, borders as taller shrubs grown with minimal pruning, as climbers and ramblers along fences, pergolas or trained up walls, and for the very small garden there is a wide choice of patio roses. These may be small, but they are perfectly formed.
Breeders must now turn there attention to bringing back more scent in new roses. Scent was a low priority in the rush to extend a new range of colours, but now people have patios and spend time relaxing around the garden, scent is a must have. The other breeders priority must now be to create a plant with health and vigour. If the changing climate is to be milder and wetter, this will favour the build up and spread of diseases, and as most effective chemicals have been withdrawn, the gardener has no means of combating disease. The only answer left is to dig out any plants prone to disease and only grow resistant types. This does mean the loss of many past favourites such as Golden Showers, Blue Moon and the old English shrub rose L D Braithwaite which had lovely deep red flowers.

Favourite bush and shrub roses

This is always a personal thing as everyone has their own favourites and as roses last for years it is not always feasible to keep trying new varieties.
National Trust is my best red rose with perfectly shaped flowers held upright on strong healthy shoots. However it has no scent, but E H Morse has great scent and excellent deep red flowers. Another great red rose is the very vigorous and highly scented Ingrid Bergman.
Julie Goodyear is my best yellow with Arthur Bell nearly just as good, but Julie has the vigour and more flowers. Graham Thomas, a tall shrub, has taken over from Golden Showers as my yellow climber, as it is not defoliated with blackspot. I am very sorry to lose Golden Showers, as it had brilliant deep golden flowers, and was very prolific but with climate change and withdrawal of chemicals it could not survive blackspot attacks.
Great pink roses are numerous from Silver Lining to Perfecta (a very old but reliable variety), then for scent the deep carmine Wendy Cussons is hard to beat. For the perfect bloom choose Myriam if you can find it. Dearest is a great pink floribunda. Pink shrub rose favourites include Lavender Lassie, Ispahan and Wisley.
Iceberg was always my favourite white floribunda and Margaret Merril a brilliant scented white hybrid tea.
Picadilly is hard to beat as a bicolour and has healthy disease free foliage and Rose Gaujard a lovely pink/white bicolour
New roses are prolific, so todays favourites will quickly be replaced by another, but it is always good to try out something new.

Favourite Climbers

My best red climbing rose at present is Dublin Bay, but it has no scent. Climbing Ena Harkness is a terrific red with well formed and scented hybrid tea shaped flowers. As a bush rose its failing was always a weak head which hung down. This trait is a distinct advantage in a climbing rose as you can look up into the full blooms.
Gertrude Jekyll has to be my best pink with very scented flowers with the Old English rose shape.
Climbing Iceberg is a great white, but suffers mildew too much, so it will never compete with the very old favourite Mme Alfred Carrier. This is very vigorous and needs a lot of space to grow. This noisette rose was bred in France and introduced in 1879 and is still in great demand.

Summer cultivation

Dead heading once flowers have finished is essential for appearance as well as preventing the bushes from spending their energy producing seeds at the expense of flowers.
Keep the soil weed free and give a mulch of compost in spring to conserve moisture.
Use a good pesticide and fungicide to prevent any build up of greenfly or diseases. All of these chemicals available at garden centres are now very safe and environmentally friendly.
The pesticides previously available to control all the garden problems are now all off the shelf.
Climbing roses usually benefit from some summer pruning to cut back flowered shoots to a strong bud that will grow and give some late flowers. There is usually a lot of weak and blind shoots that can be removed to allow more light and air into the centre to ripen up remaining shoots.
Tie in any straggling shoots so they do not get broken.
