Internet Gardening


INTERNET GARDENING

The first week in December is turning out to be the perfect time to talk about internet gardening. There has been so much snow dropped during the last week in November that you can forget even seeing where the garden is. The allotment is inaccessible due to blocked roads and the cold greenhouse has over a foot of frozen snow on it.
As I write this wee feature in the comfort of my warm home I look out onto a black sky about to offload another six inches of snow, then, when it clears thirty minutes later, and the sun comes out to show a brilliant winter wonderland.
The early winter was well forecast, so ample provisions have been acquired from my allotment to see us through a few weeks of bad weather.
Probably by the time you read this all the snow will have melted, and the winter jasmine will be in full flower, but then again I could be wrong.
Over the last ten years or so I became part of that fast growing band of silver haired surfers. Schools teach computer studies from primary age, so our kids are well versed up in internet technology.  My generation has a lot to catch up on and although there is plenty courses in basic computing, it is not easy to adapt to this new technology when you have never ever put a finger on a keyboard.
Looking back it has been a huge struggle to learn computing language and practices, but when you have the basics mastered a new world opens up that has no boundaries.
We are now at the stage where just about anything you want to know about gardening or anything else is just a few clicks away, and if you want to chat to like minded people who may know the answer to your gardening problems you just join any number of forums dedicated to your topics of interest.
There are still very many people who have not as yet embraced the internet revolution so I will add a few words of encouragement to try and get a few started.

My first steps

Fear of stumbling into the unknown held me back in many areas of modern life, but I always got there eventually. I was the last to get a colour TV, the last to get a microwave, video, digital radio,   digital camera and I still play my LP records and we still enjoy our terrestrial TV. One day I will get a mobile phone, but no great rush.
However I was more determined to get a computer as I thought it would help me sell my paintings and prints if I had a website. That would bring me into the modern world if I could handle the massive learning curve.
About ten years ago I enrolled onto an evening class for basic computing learning a wee bit about all the parts and how they worked. Still not enough to get me started.
I found another course on learning to surf and search the internet. I was getting better but was very slow as the keyboard, which I had never used before, really had me baffled. It took me nearly ten minutes to find the letters to type my name, and don’t expect them to start with capitals. I hadn’t got that far yet.
The next year I enrolled on another course, “Computing for the Terrified”. Now I felt more comfortable with that, but then I was subjected to a host of new terminology that was hard to get a grip on. Now I am a Scotsman and I know what a bar is for, but task bar, address bar, tool bar, menu bar, navigation bar, status bar. Give me a break !!!
The young lady sitting next to me was very helpful as she helped me to find the key called shift. She was planning to go on the new course, “European Computer Driving License” That was excellent advice. A new venture to try, so I enrolled at Kingsway Tech and started to broaden my knowledge base, to include scanning and printing.
At this time Dundee Business Gateway was running a series of courses on computers, the internet and website building for small businesses, so yet again this very determined lad enrolled on all of them. I got enough information on just what to look for to buy my first computer with confidence. Now I could practice all these lessons I had been taught. Before long I was searching, emailing, scanning, adding pictures from my camera, printing, booking buses, trains, holidays, and building up a list of my favourite sites that I look at frequently. I think I was ready to build my own website.

My website

The course at Business Gateway showed you how to build two pages with text and images which then linked to each other. More information was added on optimization to help your site get found by Google. If I could create a two page website it was easy to add more pages as the need arose. The format was just the same.
My site which I called www.johnstoa.com started of as four pages for paintings, and the same for prints, but then I added one for art classes, one for exhibitions and there was always a need for more.
My garden had always been a source for paintings, so I started to add garden pages. As I searched the web for interesting websites relevant to art and gardening these got added into a links page.
My site is now over two hundred pages and big enough, but since I do a fair bit of gardening research I needed somewhere to document these activities. I now incorporate all my gardening activities into these features for the Dundee Courier and archive them in date order in a new blog.
Each one has its own heading so topics can easily be extracted. Since it is my intention to add my artwork activities as well as gardening my blog is called, the “Scottish artist and his garden”.

Learning computing has been a big uphill struggle, but a lot of the problem was lack of keyboard skills. The end result was opening up a new way of living where the computer is used for every aspect of life from checking the weather, the roads, artists and art galleries, cooking recipes, history, geography, cinemas, football results, lottery results, (still waiting on the big one), music and telephoning family and friends with Skype, and off course gardening.

Garden Sites

Every worthwhile nursery, garden centre, grower and product supplier has a website. So do Botanical gardens, the Royal Horticultural Society, stately homes, research institutes and numerous allotment sites.
If you wish to find information, a picture or where you can buy a plant just go to Google and type in the common or botanical name and browse through the result pages. Pests, diseases, weed control, pruning, planting, composts, greenhouses, sheds, fences, polythene and numerous other products are all ready to find.
Whenever you find a really good site that you wish to refer to again at a later date you can right click the home page and save it to your favourites list.
You can look up local garden centres such as www.glendoick.com or www.dobbies.com  or if you wish to look up specialist plant growers I have happily used all of the following.
There are many excellent rose growers including www.davidaustinroses.com and his daughter Claire has a really good hardy plant nursery at www.claireaustin-hardyplants.co.uk.
I grow lots of fruit so a good grower with lots of information on his website is www.kenmuir.co.uk,
and I have been buying my chrysanthemums from Harold Walker for nearly twenty years. See his site at www.walkersplantcentre.co.uk and if you want the best nursery for begonias, polyanthus or delphiniums try www.blackmore-langdon.com. They are not cheap but you will get excellent plants.
When you need to protect your crops from birds with netting or you need plant pots or trays or many other garden products try www.lbsgardenwarehouse.co.uk

Education and Research and Allotments
Our own Dundee botanical gardens can be found at www.dundee.ac.uk/botanic  and for the latest in crops research browse over the website of the Scottish Crops Research Institute at www.scri.ac.uk
This is research at commercial levels but for garden information on everything, you cannot beat the Royal Horticultural Society website at www.rhs.org.uk
There are many allotment sites worth checking out. Try www.allotment.org.uk which has links to everything you are likely to grow except saskatoons. You will need to try my website for that.
Then check out both the National Society at www.nsalg.org.uk and the Scottish Society at www.sags.org.uk
You will soon find there is a wealth of great sites to browse round. Enjoy them.

The Winter Garden


THE WINTER GARDEN

A keen garden lover is happy to wander round the garden enjoying the colour of flowers and foliage, scents, texture and shapes of attractive plants at any time of year. The growing season produces a wealth of interest, but it is a bonus when some winter beauty can be enjoyed to brighten up the long cold dormant season. There is quite a wide variety of plants suitable for creating a winter border that will provide a splash of colour on any bright cold day.
Many, e.g. dogwoods, are enhanced with a bit of frost on them or emerging from a blanket of pure white pristine snow.
Information on suitable plants is available in numerous gardening books and magazines or on the internet through Google, or visit your local garden centre or plant nursery.
When the summer flowers fade, the last roses get frosted and the few remaining leaves with autumn colour fall off, this is the moment the winter garden starts its display which continues through the long winter months of cold weather and short days.

Plan the garden

It is a useful exercise to make a list of all the different types of plants you wish to grow, pondering through gardening books, visiting garden centres, botanical gardens or National Trust gardens of stately homes or look through gardening magazines to find out what can be grown successfully in your own area.
Consider ground cover including heathers, coloured stemmed shrubs and trees, flowering shrubs, scented shrubs, climbers and some early flowering bulbs.
Choose a spot that will catch the winter sun and make sure it is well drained, but not dry. Cultivate the soil, adding plenty of garden compost or other organic material to improve the soil structure and add humus. My winter garden is based on heathers, coloured stemmed trees and shrubs, winter flowering shrubs and climbers and a carpet of bulbs in layers to add and extend the interest well beyond the winter. Once you establish drifts of bulbs, soil cultivations can be very tricky if damage to bulbs is to be avoided therefore it is wise to top dress with a mulch of well rotted garden compost in early winter after clearing up old leaves and weeding, but before any bulbs begin to grow. I also top dress with compost from old tomato growbags, compost from hanging baskets, tubs, pots or seed trays. These all add humus which not only improves the soil but also darkens it which helps to show off the bright colours of shrubs, then flowering bulbs.
Always check your old compost for any vine weevil larvae which often hibernate in pots but are very easy to spot as they are white with a brown head and clean.

It is far better to bring all the plants with winter interest together to create a display with impact and if possible site the border against a dark fence, wall or evergreen hedge.

The winter season

In past years the winter garden began its season in late autumn as other plants in the garden were going into dormancy. The recent climatic changes brought about by global warming effects have given rise to an extended season for many plants. We now get roses and geraniums up to December, though not this year. The autumn leaf fall now happens in early winter and yellow Winter Jasmine begins to flower in October. It makes a beautiful Christmas table decoration combined with red carnation (purchased.)
Spring flowering bulbs no longer wait for spring but are ready to put on a show from January onwards. These really are a bonus for the winter garden.

The show begins when the tree and shrubs lose their leaves to reveal the brilliant red  stems of Cornus sibirica Westonbirt and Mid-winter Fire, bright green stems of Kerria japonica and Leycesteria Formosa and the dazzling orange stemmed willow, Salix britzensis emerging from the ground cover of the black grass, Ophiopogon planiscapus nigrescens. This grass is quite black forming dense ground hugging clumps that give a perfect background to both the bright stems and also a drift of snowdrops. Now white on black; that’s different.
I did have a black stemmed Cornus kesselringii but I am afraid it was a curiosity, not quite a thing of beauty to warm the heart and soul on a cold winter’s day so it has been relegated to the shade border.
If you wish to try some grey stems look out a Rubus giraldianus, but treat it carefully as the vicious thorns make it perfect for any vandal prone areas. It is very popular with local authorities for barrier planting to stop people taking shortcuts over roads. Another excellent tall shrub is the violet willow, Salix daphnoides which has a beautiful grey bloom on its stems.

Specimen trees

As well as shrubs with coloured stems the heather garden is often at its best in winter. It can be enhanced with a magnificent specimen birch tree Betula jaquemontia with pure white bark in a central position within a drift of gold and crimson heather, Calluna vulgaris Beoley Gold and Beoley Crimson. All of these plants are enhanced with the first cold evenings and a bit of frost. The heather garden must include drifts of winter flowering Erica carnea Springwood White and Springwood Pink.
For those in a more frivolous mood in need of the perfect small specimen tree, I recommend the Japanese maple Acer palmatum Sangokaku and although it is not cheap, it will not disappoint. After the vivid colour of the autumn leaves fall off the bright wine red stems are brilliant in sunshine.
Climbing plants and wall trained shrubs can be grown on all fences and walls to add beauty, colour, scent and a dark background. The winter flowering yellow Jasminum nudiflorum is superb at this time of year.

Winter scent

For a strong scent try the winter flowering Viburnum fragrans or the variety V. bodnantense Dawn, but for a subtle perfume the yellow flowers of the Chinese Witch Hazel, Hamamelis mollis are very welcome. The latter also has excellent autumn colour.

Spring arrives in February

The winter garden would be incomplete without a heavy planting of spring flowering bulbs drifted in amongst the shrubs. The show starts in February when the Aconites, Snowdrops and Hellebore all compete with each other to see who can flower first, followed by the Crocus species. The large Crocus hybrids flower a week or so later, but what a fantastic display they make.
Snowdrops and dogwood make an excellent combination as does the black grass with either.

Maintenance

In March there is always the occasional warm spring day that brings out the best from the flowering bulbs, and then we know that winter is past. Large drifts of brilliant crocus give way to the first early Narcissi and daffodils. February Gold usually leads this group, though in Scotland more often in March. Above the daffodils, the Kerria japonica now puts on its show of yellow flowers for a few weeks, before the first of the tulips, underplanted amongst the cornus push up and open into the sun.
At the end of March the buds on the shrubs will start to grow, so now is the time to prune them back to a stool just above ground level to encourage the growth of strong young stems that have the brightest colouring. Assist this growth with a light dressing of nitrogenous fertilizer, but only after the flowering bulbs have finished. However I do not prune back the Kerria or Leycesteria. These get a light pruning after flowering by removing some older shoots back to decent fresh young growth.
Although the coloured stems have been pruned and the early spring bulbs are finished, it is still possible to use this border for a further show of summer flowering scented lilies. These are quite tall and grow through the shrubs into the light to flower. All these plants seem to work well together without any overcrowding.
The show goes on.

Garden Trees


GARDEN TREES

I think I first became aware of the beauty and majesty of mature trees when I worked at Camperdown Park during my gardening apprentice days. There was a wide range of  broad leaved trees all now mature and a great mix of huge conifers, (Wellingtonias and Cedars) around the park, the big house and in the pinetum, which runs alongside the golf course first tee. There was a great pride by gardeners, groundsmen and foresters in their heritage and we younger apprentices were always being challenged to, “Name that tree” to see if we were learning anything. We would be in deep trouble if we did not know about our own Dundee weeping elm, the Ulmus glabra camperdownii and know the exact spot of the original tree now protected with a wee bit fence.
Dundee has a fantastic collection of trees of every kind inherited from the days of the Jute Barons, Scottish plant explorers, wealthy private estates and especially Camperdown Park awarded to Admiral Adam Duncan for defeating the Dutch Navy in 1797. The estate forester at the time, David Taylor found the Camperdown elm growing wild and now it is planted all over the world.
There are beautiful examples of mature specimens of oak, lime, beech, walnut, sweet chestnut, cedars, Douglas fir and even the more exotic Monkey Puzzle, Incense cedar and eucalyptus found all over Dundee, as well as those unusual forms of weeping ash, weeping oaks and upright oaks and hornbeam.
As much as I loved all of these trees, I was never going to have enough room in my small garden for even one of them, so my arboricultural plantings needed to be of a more modest nature.

Small Garden Trees

My first garden could only take a very small tree so I wanted one that would flower. At this time there was an avenue in Camperdown Park known as the Laburnum Walk which was very impressive in spring. So that was my choice, a Laburnum.
Everything was fine for a couple of years till the main stem got girdled with canker. I was about to lose my first tree, but a journeyman gardener suggested I remove some of the healthy branches and use them to perform a bridge graft over the cankered area. My first lesson in grafting worked a treat and saved my tree. I was now ready for another small tree.
I just love cherry blossom and if you can get one that is scented what more can you want. Prunus Amanogawa has these attributes and grows upright so is easily accommodated in most gardens. Gaining confidence I had an urge to go evergreen.
The huge Camperdown conifers were very stately but I just did not have room for a cedar, monkey puzzle or Wellingtonia, but I could manage a small upright golden yew, Taxus baccata fastigiata aurea. Later on I would acquire a whole range of conifers all of modest proportions suited to both small and medium sized gardens.
My favourites at this moment are Thuja occidentalis Rheingold and the dwarf form of Weymouth pine, Pinus strobus nana, and every garden can find room for at least one dwarf Pinus mugo.

Planting trees is for the long term so it is very advisable to do some research with gardening books in your library, or at a local garden centre or for the more modern gardener with a computer go onto Google. You will soon come across those trees you really like and of a size to suit your own garden.
In the past too many people just went for the cheapest available and ended up with a Leyland cypress and globally creating such a nuisance that laws needed to be introduced to tackle the problem.

Many of my garden trees started off as dot plants in a flower bed designed to add height and contrast to the flat, but bold colour display of Begonias and geraniums. Eucalyptus,  Cordylines and the date palm, Phoenix canariensis are perfect in summer flower beds, but in autumn when the summer flowers are past what do you do with these dot plants.
I always find a home for them somewhere, but remember with global warming they may survive our milder winters and put on a fair bit of growth.
Every ten to twenty years we get a bad winter, like last year, which really tests the hardiness of garden plants. My eucalyptus tree, now over 50 foot tall, got quite a fright and shed a few leaves, but it has survived. The young Cordyline just a ten foot baby survived unscathed, but my exotic date palm got cut down to ground level. It is still alive, just, so time will tell if the crown will yet again grow into another brilliant specimen. Never be too quick to give up on plants that have been frosted. Often they can grow again from the base.
If there is room in the small garden find space for a lilac which will be covered in white or lilac scented flowers in early summer. They do not grow too big.

It is sometimes difficult to distinguish a small tree from a large bush. Cotoneaster frigidus grows the same height as the lilac, but is more of a tall shrub. Then another very tall shrub or small tree is the Eucryphia Rostrevor. There is an absolute beauty in Camperdown Park near the pinetum covered in white flowers in late summer. It has a broadly columnar habit and can reach 30 feet or so depending on soil, shelter and climate.

Specimen trees

Sometimes the small garden can get a boost with a particularly good form of tree planted centrally in a lawn or other conspicuous spot.
The small garden can use the graceful silver grey willow leaved pear, Pyrus salicifolia pendula, or if there is more space the dazzling white stemmed birch, Betula jacquemontii. Then for a bright golden splash of colour all summer plant a Robinia frisia, but remember it needs good drainage.
Another good specimen tree is the weeping birch, Betula pendula youngii. It is very graceful and quite small but extra height can be encouraged in its young growing stages. Buy a young specimen and train the main growing stem up a very tall cane for a few years. I got mine over twelve feet before I let it grow as a weeping tree.
An excellent flowering specimen tree with an architectural shape is the Japanese Mount Fuji cherry, Prunus Shirotae. It is outstanding in full blossom.
Some tree species have columnar growing forms that do not take up too much space, at least in the early years. The upright Cypress oak, Quercus robur fastigiata , (several along Riverside Drive), is very majestic and quite similar to the upright form of hornbeam, Carpinus betulus fastigiata.

It is the larger gardens that have the space to indulge in the finest tree specimens from the modest Liquidambers to the weeping silver lime, Tilia petiolaris. Now that will make a statement, but then, so will a perfect specimen of the blue Atlas cedar, Cedrus atlantica glauca allowed to retain its branches down to ground level.

Apologies for all the inclusion of the boring bits, (botanical names), but if you want to make sure you get the correct plant you will need its proper botanical name. Plants usually only have one botanical name but numerous common names that differ depending on where you live.

Tree Care

It is very important that you are aware of just how big your tree will grow to on maturity so you can plant it with due regard to any future problem.
If trees are planted for shelter or screening around boundaries keep them well away from your neighbours property, and make sure they cannot block street lighting columns, road signs, and site lines at road junctions.
There is healthy debate on how close trees should be planted to property and different bodies give different views. Some say the distance should be from one to one and a half times the trees ultimate height from the base of the property. However trees all vary, and some are very little problem, whereas others such as willow and poplar should be kept at least twice the ultimate tree height and not near any known land drains as they have strong root systems that will seek out any available water.
Trees planted too close to buildings can be a big problem in dry spells as they will extract moisture from an already dry soil. On a shrinkable clay this can cause the ground to heave once the rains return. If any foundations are not up to scratch building walls can crack.
Now you know the pitfalls you can select your specimens with more confidence.

Garden Climbers



CLIMBERS FOR EVERY OCCASION

I first became aware of the possibilities of climbing plants at the beginning of my gardening career when my small council house garden was just not big enough to grow all these plants I was learning about. By utilising all walls and fences I could extend the range.
It soon became clear that there were plants that would enjoy a north facing wall, whereas the more exotic climbers would thrive on a south facing wall.
A new world emerged for the young very keen apprentice gardener who lost no time in covering every available wall and fence space. The house soon blended into the landscape.
Fences erected along property boundaries, or separating garden areas, or creating privacy and shelter around patios would all be enhanced with scented flowers and autumn berries.
Being a fruit lover these walls and fences would provide the correct conditions to grow many fruit trees and bushes where space was at a premium.
As life moves on the garden is now a lot bigger, but so is my knowledge of plants that I want to grow or experiment with. So I am back to the original problem of not having enough room. I need to be quite selective on what plants I choose to grow..

Special needs

My first success was finding plants that would grow on a north facing wall where good sunshine was a problem. To convert a dull dark north wall to one with flowers was a great achievement. Climbing rose Mme Alfred Carrier, or Ena Harkness and  Jasmine are all  good.
Then what about the east wall where early sun would affect any late spring flowers if there was a late frost. Choose something that flowers in summer.
I placed a great value on walls next to main front doors. These needed scented flowers to enhance the feel good factor for anyone going into the house.  Climbing rose Zephirine Drouhin and Gertrude Jekyll are both perfect pinks for this spot.
Property security can be improved by planting Pyracantha around any vulnerable windows. They can also thrive on north facing walls and although very vigorous, they adapt very well to spur pruning to keep them close to the wall while retaining their thorny framework and bright autumn berries. Blackbirds just love to nest in them.
Walls and fences are becoming very popular places to plant fruit trees and bushes on as people now want an apple, pear, cherry or peach but normally they would grow quite large, so nurseries now cater for this use. Espalier trained trees, smaller growing stepover trees, and dwarf cherries are all now available. Now cherries grown on the new Gisela 5 rootstock will only grow to six to eight feet tall, so can easily be netted against birds so you get the fruit and not the birds.

Supports

Some plants support themselves and climb using their twining tendrils e.g. vines. Others will twine around any support, e.g. honeysuckle and clematis, some attach themselves with adventitious roots appearing in the shoots, e.g. ivies, but many others require an artificial support to be trained against. Most climbing roses will need support as will Pyracantha, and fruit trees. Wooden fences may give support by way of their construction, but can be enhanced with strong wires stapled firmly along its length. Trellis is very useful as well as six inch weldmesh. Walls can be drilled and vine eyes inserted to hold strong horizontal wires for training. Every situation will be different and each plant will have its own particular needs.
An overgrown leyland cypress hedge can be cut back to ten feet or so and most of the branches removed, just retaining enough to keep them alive and give support to a few climbers. Allow some regrowth, but not too much to create a nuisance. Clematis will thrive here and some climbing roses can be added. In time the clematis will hold onto the climbing rose  and keep it upright.


Soil

Very often there will be a perfect house wall space but totally paved with no soil near it. Most plants only need enough soil to get them started. I have frequently removed a two by two slab against the house wall then excavate ten inches of builders rubble before loosing up a further six inches. Backfill with some decent top soil adding a bit of compost and some fertiliser to the pit. Keep any new plant well watered till it gets established. It will soon find spaces to grow in the builders rubble and be perfectly happy. My climbing rose Dublin Bay will reach seven feet in height according to the catalogue. However once the roots found the rubble it just grew and grew and now I have had to severely prune it to keep in down to twelve feet.

Seasons

Climbing plants can add interest all year round by using the benefits of each different wall. South facing walls catch the most sunshine so will bring plants on earlier and retain colour longer at the end of the season while north facing walls extend the plant range to those that would otherwise suffer too much sun.
North facing walls are perfect for the yellow winter flowering Jasminum nudiflorum which starts to flower at the beginning of winter and continues for a few months. Camelias on a north wall can follow on into the early spring, and being a woodland fringe plant they do not mind shade as long as they get some sun in summer to ripen up the wood to allow flower buds to develop.
Clematis in its numerous varieties and hybrids will give a display from spring till late summer. Clematis montana rubens may be very common, but it is one of the best for a mass display of pink flowers. It is very reliable, quite vigorous and loves to scramble into old trees, over sheds, tall fences, conifers, etc.
Where scent and flowers are both important go for a honeysuckle. That will take you into summer. Now there are numerous climbers and ramblers to choose from. Roses are very adaptable, but choose a variety that has disease free foliage able to resist black spot, mildew and rust. Chemicals available at garden centres have to be very safe for public use so are usually quite dilute and do not always work effectively unless you spray at fortnightly intervals and each spray does not get washed off with rain soon after application.
My favourite autumn climber for any wall is the Firethorn, Pyracantha Orange Glow, though there are several yellow and orange berried forms.

Fruit bushes

Redcurrants and gooseberries can be trained as cordons on an east or west wall, but keep your south facing walls and fences for those fruit that can benefit from more sunshine.
Apples and pears trained as fans or espaliers thrive on a south wall, but so also do figs, cherries, peaches and the vine Vitis vinifera Brant. The vine needs support for its tendrils to hold onto. It has small but very edible fruit and brilliant autumn colour.
All of the fruit trained against walls require pruning specific to their individual needs to control growth, expose fruit to the sun and ripen up shoots to fruit the following year.
