PLANTS FOR PROBLEM AREAS

PLANTS FOR PROBLEM AREAS

Helianthemum

My life in the gardening world has taken me all round the country. This has given me the experience of working with a huge variety of soils, sites, climates and problems which had to be solved with a suitable plant cover. Some sites around the coastal areas were very dry with soils containing a lot of sand; others down south were shallow and overlying gravel beds or chalk. In the midlands there is a lot of deep but fertile clay soils in the country areas but many industrial towns had no soil what so ever. It was normal practise to buy in top soil for our landscape works in the Midlands, and the north east had stiff heavy clays that could hold too much water. Some coastal areas suffered a lot of wind exposure and salt sprays which could desiccate the leaves of vulnerable plants. The south east (the fens) has a lot of flat peaty soils reclaimed by draining, and some areas around Manchester have very deep peat soils with drainage problems. In Scotland we have a lot of boulder clay soils left over from the last ice age, but when well managed they can be very productive. However our country is not flat so we have the added problems of dealing with gardens on a slope. Shade from buildings and tree cover needed solutions. Building often created wet shade while trees often created dry shade, as the roots absorb moisture from the soil which is then lost through transpiration from the leaves.

Cistus Silver Pink

Most plants are very tough and adapted to growing in their own environment. It was our job so sort out the best plants for each situation. I worked as a garden designer for large scale local authority projects, but also got involved at individual garden level. Whatever the location, soil, or problem it was our job to find plants for all these situations.

Many areas exposed to the coast can suffer gales as well as salt spray. We all see the affect of this salt damage on grass verges along the highways after winter as the road salt usually kills out vegetation a few feet from the kerb. In gardens we can plant up those plants known to tolerate wind and salt to some degree. Escallonias, broom, sea buckthorn, holly, willow, eucalyptus and tamarix, and at ground level use pinus mugo, senecio, rosemary, lavender, delosperma or euonymus and for flowers the shrub rose rosa rugosa, cistus and red hot pokers will all have a place.

Red Hot Pokers

Most of these plants can also be used on soils away from the coast but still suffering from dry conditions. Other favourites can include the hardy outdoor fuchsias, all kinds of heathers, cotoneasters which vary from ground cover to small trees, gorse, and for the exotic garden try the yucca, New Zealand flax or the palm tree, Cordyline australis.

Many gardens suffer steep banks that make maintenance a problem so we tend to plant them up with ground cover which also smothers weeds. Heathers, camellias, dwarf rhododendrons and evergreen azaleas are useful but if the garden gets too much shade you can use variegated ivy, euonymus, London Pride, dwarf pines, pernettya, mahonia and viburnum davidii. However if the steep banks get a bit of warmth and sunshine this allows another range of plants. Flag iris, Helianthemum, the dwarf rock rose, senecio, hardy fuchsias and flag iris will all enjoy a steep well drained bank in the sun.

Outdoor fuchsia

Wet soil problems vary from damp soil to ponds and each has its own range of plants adapted to the degree of wetness. Cornus, willows, aronias, ornamental elderberries, bamboos, spiraea and snowberry are all fine as long as they do not get too much waterlogging.

All fruit bushes and trees can benefit from a mulch of rotted manure or compost about two inches deep. Make sure all weeds have been removed before spreading the mulch. It will conserve moisture and add nutrients as it rots down. The plant will also benefit as surface feeding roots will not be disturbed or killed by hoeing. The mulch is also useful under gooseberry bushes to assist prevention of sawfly maggot infestations.

SPRING IS ARRIVING

SPRING IS ARRIVING

At long last the rains have stopped and the soil surface is beginning to dry out. The last week of February was a real bonus with dry sunny days and just a slight frost over night to firm up the soil surface. Winter digging has now been completed, and all my entire compost heap used up, but the beginning of the new one has got a start. Kitchen waste is always available, and grass cutting has now begun. Add to this the wood shredding from the prunings of all the roses, raspberries, currants, saskatoons, gooseberries, brambles and grape vines. Our allotment site shredder is having a busy time just now, and the shreddings are perfect for the compost heap or as a mulch under some fruit bushes. They are also useful on paths to keep weeds down for the season.

Iris reticulata

The sunny days brought on the spring flowering bulbs and although the aconites and snowdrops are past their best, the crocus are now taking centre stage. A small batch of Iris reticulata planted a few years ago is now beginning to form a strong drift of colour that will thicken up each year. Anemone blanda planted about ten years ago is now appearing in many different borders, probably from seed mixed in with the old leaves and collected for the compost heap, which then gets spread all over the garden. This plant is not invasive so we just let it grow where ever it wishes and the drifts of bright blue flowers at the end of February and into March are always a welcome sight. My ground cover yellow saxifrage is now in flower as soon as it senses

Primulas ready to plant

spring is approaching.

Outdoor plant tubs and hanging baskets are always liable to plant losses especially as the winter has been so wet, but garden centres and many other outlets are just full of spring bedding flowers at very reasonable prices, so go for some of these and top up the tubs and baskets and find a few extras for gaps in borders. Primroses, polyanthus and pansies are all looking great at point of sales as most of them will have spent winter under glass or in the protection of poly tunnels.

Garden centres and numerous supermarkets are now stocking fruit trees and bushes as we head into spring. I have seen a lot of plants for sale in Dundee that are just not suitable for our climate. Scotland is colder, wetter and has less sun than the south of the UK, so some plants that are just fine in the south are just not suited to a cooler climate.  Always check out the variety before you buy.

Saxifrage

My new bramble (blackberry) Reuben gets brilliant reviews with immense sweet berries so I thought I must try out this primocane type. This means it gets cut down to the base every year and fruits at the end of the new shoots produced in the same season. Planted a year ago and cut down to a few inches it soon produced a couple of shoots. However these did not flower till November so I had little chance of seeing any berries. Last year was a rotten year so too early to judge. This year the winter has been very mild so my bramble has been growing for a few weeks, only to get the young soft shoots frosted by a couple of degrees of frost. Still too early to judge.

Seed potatoes for the allotment are now all boxed up for chitting and placed in a cool but frost free room near the window. Hopefully the young shoots will emerge but remain stocky and be ready for planting out towards the end of March or early April depending on weather at that time.

White Orchid

Rhubarb crowns are now all swelling up and looking very promising. The mild wet winter seems to have done them no harm at all.

My cold greenhouse is rapidly filling up as plants get transferred from windowsills and other seeds get sown. Begonias are still at home but will need to go out in a few weeks time.
Indoors, the white Phalaenopsis orchid is in full flower. They are great value as they last for weeks.

Wee jobs to do this week

Geraniums grown from cuttings last autumn as well as stock plants dug up and potted into large pots are now all putting on a lot of growth. Some are getting too big for windowsills. I have transferred the strongest looking ones to my cold greenhouse to harden off, but to keep them short jointed remove the tops and use these as a batch of cuttings. They root easy but need warm conditions indoors on a shady windowsill.

BEGIN SEED SOWING

BEGIN SEED SOWING

Looks like spring is coming early this year, or maybe the garden has awoken earlier due to lack of a winter. Although it has been very wet under foot the temperatures have been mild so the garden plants have not been hanging back. Aconites, snowdrops and crocus have all been showing flowers for several weeks, and it looks like the daffodils and tulips won’t be far behind, so it is time to get the show on the road and start off with the seed sowing. I make a start at the beginning of March to sow my tomatoes, onions, peppers, broad beans and sweet peas, and my tuberous begonias will get boxed up and given some heat as they need a long season. However my plants are for general use. If you are an exhibitor you will have started a couple of months ago to get the advantage of a longer growing season. We all have adopted our own system for sowing early crops. As my greenhouse is not heated, I rely on having plenty of warm windowsill space for germination.

Sowing tomato seeds

Broad beans and sweet peas are both quite hardy but need warmth to germinate. I sow broad beans individually in cellular trays with 15 pots of 7cms size to a standard seed tray. Sweet peas can also go in these cellular trays, but a slightly bigger pot will give a better crop when you put three seeds in each pot. Once these have germinated and grown on for two to three weeks they can be put in the cold greenhouse for a few more weeks before planting out at the end of April. After several leaves have formed pinch out the main stem to encourage branching. If you wish to grow them as cordons for bigger flowers then select the strongest shoot once the new growths emerge.

Tomato seedlings ready to prick out

Onions are sown in smaller cellular trays of 40 cells per tray and germinated in a warm place. Seeds are sown individually but if two or three seeds land in a tray just leave them to grow. You can pot up these plants into the next cell size later on or just plant as soon as they are hardened off. Do not separate plants if some cells have two or three plants together. They will be going into well manured ground that is very fertile as they are heavy feeders. This year I will try Globo.

Broad Beans

Tomatoes and peppers are sown into shallow seed trays and both these need warmth at all times. Sow thinly so seeds remain stocky, then prick out into individual pots before they get too big. Mind you it is easy to sow thinly when there is only ten seeds in the packet. No chance of sowing half the packet this year and keep the rest for next year. This year I am growing my favourite Alicante plus the yellow Sungold and my best cherry, Sweet Million. They will always need heat and good light so do not be in a hurry to transfer them into a cold greenhouse unless it is lined with bubble polythene and you have a heater handy if frost threatens.

Boxing up tuberous begonias

Tuberous begonias can now get boxed up with good compost and placed in a warm place. A dark corner is fine for a few weeks as they are quite slow to grow, but once the shoots emerge bring them into the light. I start mine off spacing them quite close together then once I see where all the shoots are I transplant them into bigger boxes and give them more room. As my corms are now about twenty years old they are a fair size so this is a good time to split the corms as long as each section has a couple of strong shoots. I just use a big knife and chop them up to no harm.

Wee jobs to do this week

Strawberry plants bought from nurseries are often fresh dug in the autumn, but cold stored for planting in spring. Although they don’t look great without leaves, the crown is strong and once warmer weather arrives they soon burst into growth. There are now so many new varieties that it is always interesting to try something new. This year I will try out a new early strawberry Sweet Colossus and a new Everbearer called Albion to extend my season. My existing perpetual strawberry Flamenco, stopped producing runners and has died out during the wet sunless winter.

GARDEN TREES

GARDEN TREES

Every garden can benefit from a few trees to give them scale, height, flowers, autumn colour and fruit. Trees encourage birds and other wildlife, screen eyesores and create impressive specimens in lawns and borders. Trees can be selected for any size of garden and may be ornamental, flowering and fruiting.

The largest gardens can enjoy a good specimen Cedar, silver weeping lime, purple beech or maple, but as garden size gets smaller we just choose the next smaller size to suit. There are numerous upright tree forms which can be very impressive but don’t take up much space such as hornbeam, oak and the upright cherry,

White stemmed birch tree

Prunus Amanagawa only needs a square metre. The weeping birch Betula pendula youngii makes a brilliant specimen, especially if you train the leader upright for a few years then let it weep. My other favourite birch is the pure white stemmed Betula jacquemontii, making a very impressive specimen in all seasons. Then in Scotland you must find space for a rowan, now available with a wide range of different coloured berries.

Another favourite but needs space is the Eucalyptus gunnii. It is evergreen, hardy and fast growing.

Maples come in all sizes and the Japanese types such as Sangokaku makes a small tree with terrific autumn colour then attractive red stems in winter after leaf fall.

For the very small gardens the Kilmarnock willow and the dwarf weeping elm tree, Ulmus camperdownii, is well worth planting as they are both very attractive and the

Cordyline australis

Camperdown elm is our local elm. For a very small garden you can still get a bit of height with the dwarf mountain pine, Pinus mugo or slightly taller Pinus strobus nanus or the tree heath, Erica arborea. If you want an evergreen, the hardy palm, Cordyline australis is quite happy as long as global warming continues, but if we get another really bad winter it can kill the top down to ground level, though usually it survives to grow on again after a years recovery.

Flowering trees

Cherries, crab apples, Magnolias, Eucryphia, Lilac and Amelanchier are all perfect for smaller gardens. Prunus Amanogawa is upright and quite narrow. Prunus Shirotae is spreading, but an absolute stunner in flower. Crab apples flower then have a crop of very bright small apples, e.g. John Downie. Some Magnolias are more large shrubs, but can attain a fair height when mature.

Eucryphia Rostrevor is slow growing but will make a tall white flowering tree in time.

 

Apple Starline Firedance

Fruiting trees

If you prefer to have a fruiting tree then the choice can include apples, pears, plums, peaches, and cherries and even the fig will make a small fruiting tree. Modern dwarfing rootstocks now allow us to have apples, peaches and cherries that will happily fit into the small garden often trained against a south facing wall. Choose varieties that have healthy foliage as there are very few fungicides available to tackle scab, mildew or brown rot. I can recommend apple Discovery, Katy, Red Devil, Fiesta and Bramley for a good cooker. If space is limited try the columnar apple Starline Firedance. Victoria is still my favourite plum, and Avalon Pride a good peach with

Upright oak

resistance to peach leaf curl disease. Beurre Hardy and Concord are my best pears, but newer varieties are appearing all the time and it is good to try something different.

Wee jobs to do this week

Grape vines under glass and outdoors get pruned in December and January, but I retain several strong shoots to use as cuttings later on, but keep them moist by heeling in the soil in the greenhouse border. I take cuttings about two buds length and place then round the sides of a pot with a few draining compost. Place them indoors on a windowsill where they will get some warmth and light, but not direct sunlight. They should be rooted by late spring and ready for potting on.

Art Chain Challenge.

I was nominated to participate in this event where artists would paint and complete one painting every day for five days.
I chose Cape Gooseberries for four paintings then for my fifth image I started a new project of the Lady in Red in the City (Dundee)
These paintings are all in oil and at present unframed and available from my studio in Dundee.
Study three and Four and Lady in Red have all got textured backgrounds with palette knife work.

PLANTS FOR THE HOUSE

PLANTS FOR THE HOUSE

House plants are part of the interior décor. Some may be permanent features providing interest in corners, around fireplaces, most of which are no longer a source of heat, in the middle of a table or other focal point or frequently on a windowsill. There is a plant for every occasion, though most are subject to changes in fashion. Forty years ago it was the time for the rubber tree plant and the cheese plant, and cactus were common on windowsills even though they seldom flowered.

Sophie with a couple of cyclamen plants

Today we have a huge range of foliage plants as well as flowering plants. The Dragon tree is very popular just now and the variegated rubber tree is making a comeback, but it is the flowering house plants that make the biggest impact. Most of these tend to have their own season, though sales are always high for Mothers Day and just before Christmas as we want to brighten up our rooms for festive visitors. It is very hard to resist the big bright red Poinsettias as a festive decoration, though we could also choose a cyclamen, an indoor azalea, a winter cherry (Solanum) or the Christmas

Winter Cherry

cactus (Zygocactus). Some are grown to give one display then discarded, but others can be retained and grown on to flower every year. Nowadays it is quite easy to find growing details on the internet to let us know whether to water and feed, or dry off as each plant has its own needs. The Christmas cactus is usually very reliable and as the plant gets bigger each year it can sometimes excel itself by a profusion of flowers in December then another show again a few months later. However this will exhaust it and as I found out it needs a rest for a year.

Another cactus worth growing on a warm south facing windowsill is the Rebutia cactus.

Poinsettia

Keep it virtually bone dry all autumn and winter. It likes to flower in late spring to mid summer when it will need some moisture, then a wee bit more as it continues to grow. Then by the end of summer dry it off so it can rest till next year.

Cyclamen can be kept growing right through till spring to build up the strength of the corm, but then they need drying off for the summer. They will come back to life at the end of autumn after their rest.

Another very popular plant for year round interest is the dwarf orange bush with white scented citrus flowers followed by small oranges that can last for several months. However I can’t say the bonny wee oranges are sweet enough to eat when growing in our Scottish climate. They are also prone to scale insect attacks.

Fuchsia Southern Belle

The Amaryllis bulb is a very popular Christmas present, and will flower in late winter. To get it to flower every year it needs watering and feeding up till the end of the summer when you dry it off for about three months. It flowers best when pot bound, so do not be in a rush to pot it up.
Orchids of the Phalaenopsis type are just about found in every home as they are very easy to grow and last for years. Look after them well and they should flower every year. They enjoy the warm moist atmosphere of a bright shower room, away from direct sunlight, as they absorb moisture from their aerial roots that grow outwards from the pot, so don’t cut these off to tidy up the plant. I have had mine for many years giving me such a good display that I must have done a dozen orchid paintings, mainly on large box canvases.

Geranium, fuchsias and Impatiens (Busy Lizzie) are garden bedding plants used for tubs, borders and baskets, but will also be very happy in the house on a bright windowsill, but not in full sun.

Wee jobs to do this week

Check over tree stakes, wire supports and ties on ornamental trees, shrubs and fruit. We are often too busy during the growing season, and tend to put off this task to a quiet moment. This is that quiet moment to secure young plants for another year. Ties on trees can also get too tight as the tree swells up as it grows, so the ties may need adjusting. Make sure the tree stake is well away from the trunk otherwise it is likely to cause damage.

PRUNING FRUIT TREES AND BUSHES

PRUNING FRUIT TREES AND BUSHES

The dormant season from November till the end of March is the time when we prune our fruit trees and bushes. I often choose a frosty day or when the ground is covered with snow when I can’t get on with other work. However leave plum trees till summer otherwise there is a risk of silver leaf infection from airborne spores entering the cut surfaces.

The pruning of apples, pears, outdoor peaches and cherries has changed over the years as new dwarfing rootstocks are found, and demand to grow small trees increases as space gets restricted. So now as well as standard trees for the large garden, we can have half standard and commercial spindle bush training allowing all picking to be carried out from the ground. For the smaller garden we now get cordons, fan trained trees, upright columner forms and stepover trees only growing a couple of feet tall, (as long as you summer prune them.)

Anna picking bramble Helen

The principles involved in pruning all of these different forms is very similar. We aim to control the balance between strong growth and fruiting, and opening up centres to allow light in for ripening the fruit. Old wood that has fruited for five or more years also needs removing periodically to be replaced by some young shoots that will grow in its place for the next five years.

Autumn Bliss raspberries

However cordons, fan shapes and stepovers all fruit on a system of spurs created by cutting growth shoots to a few inches long in late summer to ripen up the shoots, then cutting them back further in winter to form fruiting spurs.

However in the early years after planting we prune to establish the shape intended for the tree as bush, fan, stepover and oblique cordon all need treated differently.

Brambles (blackberries) and raspberries are similar to prune. Summer fruiting types, fruit on shoots grown the previous year, so we remove the old shoots that fruited last year right down to the crowns at ground level, and tie in new shoots. Autumn fruited rasps and the new primocane brambles such as Reuben have all their growth removed in winter as they will fruit on shoots produced in the same year. Reuben had a bad year with me in 2015 as the young shoots flowered in November, far too late for fruiting. Hope it does better this year.

Blackcurrants fruit best on young shoots formed the previous year so we prune to remove some old wood to encourage a supply of new shoots every year.

Apple Fiesta

Red and white currants are similar but the young shoots form spurs so we retain them for several years. Try and establish an open centred framework of about nine main shoots, replacing a few of these each year as new young shoots grow from the base of the bush. All sideshoots are cut back to their main shoot to form spurs in winter.

Gooseberries are usually grown as a bush on a central leg about a foot tall. There are usually plenty of young shoots grown every year and fruiting is usually heavy so the main aim of winter pruning is to remove those branches too close to the ground to prevent fruit getting soil splashes, and keeping the centres open to make picking easier. Gooseberries like red and white currants can also be trained as cordons on walls and fences where space is limited. 

Figs up north are best grown in a sheltered spot against a warm south facing wall and planted in a prepared pit lined with slabs to restrict growth and encourage fruiting. Initial pruning is carried out to create a fan shape against

Chinese witch hazel

the wall. Subsequent pruning removes shoots growing away from the wall, keeping the centre open and reducing any long vigorous shoots. Summer prune young shoots by tipping them back to several leaves to encourage fruit bud formation.

Wee jobs to do this week

The weather has been so wet this year that outdoor gardening activity has been greatly curtailed, but it has also been very mild and this has brought forward the flowering of the early bulbs, so whenever the sun shines wander outside and just enjoy those snowdrop and aconites. Its been a good year for the Chinese witch Hazel, Hamamelis molis and Mahonia Charity, both looking great while the sun shines. Daffodils, tulips, hyacinths and many other dwarf bulbs are all well advanced and even my rhubarb crowns are all swollen up ready to start growing after this wet but mild winter.

ROSES

ROSES

Fifty year ago every decent garden had roses in beds, growing along fences, growing up walls and a few tall shrub roses along garden boundaries. However, time moves on and life changes. Chemicals previously used to combat black spot, mildew and rust are no longer available so these diseases are now running rampart through many great varieties. Roses have lost their appeal and now plant breeders have a struggle to bring in a new roses with great floral merit, scented flowers and healthy leaves with built in disease resistance. I have discarded a lot of bush and shrub roses recently, but fortunately there are still a few good ones left. Some still get attacked, but seem to survive and still flower just fine. There is still some rose fungicides available which I use for those such as the white scented Margaret Merril which I do not want to lose.

Other favourites still in my garden include the red scented E H Morse, the bicolour Piccadilly, Arthur Bell, a great yellow, the orange Dawn Chorus and the pinks Wendy Cussons, Myriam and Congratulations. Two great reds are Ingrid Bergman which has some scent and National Trust with a perfect rose flower shape but no scent.

New varieties appear every year so it is wise to try out something new and most garden centres display them in pots during the early flowering season so you can see the flower, smellthem to see if  it has a scent and see if the foliage looks healthy.

My best shrub roses include the very old pink Ispahan, the pink striped Rosa mundi and Gertrude Jekyll, another scented pink shrub rose which I train as a climber. My other climbers which have given me great value, brilliant displays and very little disease is the red Dublin Bay, now twelve foot tall and Mme. Alfred Carrier at least eighteen feet tall. It really needs a massive amount of space and takes a lot of work with pruning and tying in.

Planting new roses

Roses are permanent plants so need a lot of ground preparation prior to planting to improve the soil structure and drainage. New ground for roses should be double dug incorporating plenty manure or compost, and then dusted with a slow release organic fertiliser such as bone meal. Choose a good day for planting and don’t plant the bushes too deep. A compost mulch applied in spring is very beneficial. Planting bare root bushes can be done any time from November to March, but container grown bushes can be planted all year round as long as they are watered in any dry spells.
Prune shoots after planting, by removing about half the growth to encourage new growth.

 

Pruning existing roses

With bush roses remove weak shoots, some old wood and trim others by about a third to an outward facing bud. Shrub roses only need tidying up of old shoots trailing on the ground and periodically remove some old wood to encourage fresh new shoots.

Climbing roses need the most attention as they grow so tall and put on a lot of growth, but the principle is the same. Remove all weak shoots, try and remove some old shoots every year, but only lightly prune last years shoots as these will flower this year. Remove any shoot growing away from the wall if it cannot be tied in. Space out and tie in long shoots so they all have plenty of room.

 

Wee jobs to do this week

A cold frosty day is often a good time to prune the raspberries as the weather restricts gardening in other places. Autumn fruited varieties are the easiest as they are cut back to a few buds at ground level. New shoots emerge in spring, grow tall in summer then fruit from August onwards. Summer fruiting varieties fruit on canes grown the previous year so all last years fruited canes are removed down to the ground. They are easy to recognise as they are brown rather than green and they are all tied in rather than loose. Tie in the new canes with a running knot spacing them four inches apart along the top wire.

SOIL

SOIL

To create a successful garden, we select our favourite plants, arrange where best to put them and give them the soil conditions best suited to their needs. Some research is always handy to establish the best plants for dry soil, damp soil, poor soil, shady areas, suntraps and even on the allotment you need to know which plants need very fertile soil and those that are best on land manured the previous year. Many problems start with the new garden around new property once the builders have left the site. Poor soil, consolidation, poor drainage and buried builders debris are normal.

Once you start to dig over the site, coupled with a visual inspection you will quickly determine the state and nature of soil, and if drainage is needed.

Anna starting the winter digging

A rubble drain can often be integrated under garden paths and lead to a large sump. Soil improvement is an ongoing event involving digging annually, incorporating organic manures, practicing green manuring, establishing a compost heap and using fertilisers and rock dust to get plants off to a good start. Any areas to be planted with permanent or long term crops such as fruit bushes, shrubs, trees or roses should have the ground double dug adding in as much compost or other organic material as you can get hold off. When double digging nearly two feet deep don’t allow the soil or clay in the lower depths to come up into the top soil. Deep digging opens up the soil allowing good aeration, root penetration and improves fertility and drainage.

Adding 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. On allotments where a four year rotation is practised it is usual to lime one section each year where the brassicas are to be planted. On sandy soils often deficient in minerals consider using rock dust to improve mineral uptake.

Shredding branches at City Road Allotments

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 such as shrub prunings 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.

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, clover or tares. As soon as the first flowers appear, trample down the stems and dig it in.

Wee jobs to do this week

Pruning Black Hamburg grape vine

Prune grape vines in the greenhouse as well as outdoors. Vines under glass are usually trained as upright rods spaced about 18 inches apart with spurs established about ten inches apart up these rods. Prune all young shoots right back to a couple of buds from the main stem (rod). Grapes grown outdoors can also be grown as rods or if covering trellis, fences or sheds left to form a framework of main stems spaced about a foot apart. Again spurs are encouraged to form about ten inches apart and in November to January all young shoots are cut back to a couple of buds. Commercially outdoor grapes are trained in the single or double guyot system to form well managed rows with plenty of light and growth restricted in summer to encourage fruiting.

PLANS FOR A NEW SEASON

PLANS FOR A NEW SEASON

Although the very wet weather at the start of 2016 has not been kind to gardens or gardeners giving us precious little chance to get onto the soil, we can still do some gardening at home, sorting out plans for the new season. We have had time to analyse last year’s results so we can continue with our success stories and find answers to our failures.

There have always been continual changes around the garden and on the allotment. We have a permanent battle with the weather all year round, and then there are new varieties of flowers, fruit and vegetables to try out.

Add to that those must have trees and shrubs that have given us a lot of pleasure for many years, but eventually outgrow their allotted space. I have had to sacrifice my eucalyptus, several huge conifers, many shrub roses devastated by blackspot, my plum tree which got infected by silver leaf disease and my peach tree devastated by peach leaf curl. I also lost several grape vines, my goji and a row of raspberries killed out by phytophthora root rot.

However the gaps left behind gives us the challenge of improving the landscape design. Thus a lot of new plantings took place last year including many dwarf rhododendrons and azaleas, some osteospermums, flag iris, outdoor fuchsias and bulbs.

I had a huge ceanothus growing at the bottom of a steep bank, but during a dry spell last year it died so I dug it out. The ground was replanted with a drift of yellow doronicums around which I have planted numerous dwarf red tulips to flower at the same time. Another dry area at the top of a wall has been planted up with peonies and pinks around the edges to trail over the wall. This area has also been under planted with tall red tulips for a spring display and highly scented oriental lilies for the summer. More oriental lilies are planned for the ground vacated by removal of my forty year old plum tree as well as hundreds of grape hyacinths which naturalise very easily.

Update in the fruit garden

Last year my new autumn raspberry Polka started to fruit, and as hoped the berries were larger than Autumn Bliss, so I look forward to this year’s crop. I will try out a new summer raspberry bred recently at James Hutton Institute called Glen Dee, with larger fruit than Glen Ample, heavier yields with tolerance to some strains of raspberry root rot.

Bramble Rhuben will now be in its second year, so I hope it fairs better than last year. This is a primocane type fruiting on new shoots produced in the same year. However last year some of these new canes flowered in November so never had a chance to fruit, though it was a cold sunless year.

Blackcurrant Big Ben gave a good crop of large berries so hope this continues this year.

Aronia Viking gave us its first crop last year, but as the bush grows the cropping potential will increase, so 2016 could be a good year, with enough for a demijohn of wine.

My original outdoor peach tree Peregrine, grown against a south facing fence had to be dug out as the peach leaf curl could not be controlled. It has now been replaced with peach Avalon Pride said to be resistant to this disease, so here we go again.

In the greenhouse my new grape Siegerrebe was quite promising, giving white grapes with a Muscat flavour, so I took some cuttings and will try this one outdoors on a south facing fence.

Starline apple Firedance planted last year gave a few apples, and in the cool wet summer growth was fairly decent, so it will be interesting to see what it does this year.

Wee jobs around the garden

Winter aconites are now beginning to flower a lot earlier than normal due to the mild winter. Where a drift is forming from scattered seed these are now germinating but only produce one set of seed leaves in the first year and no mature leaves. The second year they produce one mature leaf, and then hopefully begin to flower in the third year. Make sure you can recognise these young leaves so they don’t get mistaken for an early flush of weeds.
