LOOK BACK OVER THE YEAR



LOOK BACK OVER THE YEAR

Every year has its own stories to tell, and they are never the same. No matter what skill level we possess or how much knowledge we have, the success of the garden still depends on the weather and how we learn to work with it. This year started off with a mild but very wet and stormy winter, then ends up with good weather, so I completed all my winter digging in before Christmas.
It all started to go wrong, when last year’s December gales blew my greenhouse down. It took me three months to sort out a new one strong enough to withstand the next gales sure to blow up the Tay estuary and rattle the glass. I spent three days picking up shards of broken glass from both my garden and my neighbours. The new greenhouse base was strengthened and raised so I imported good top soil for the borders. Growbags intended for my tomato crop got opened up and the compost forked into the borders. Tomatoes went into this prepared soil and could not have been happier as some reached the eighth truss instead of the normal four to five.

The year started very wet and an almost total lack of snow and frost. Snowdrops were in flower in January, and other plants were at least two to three weeks ahead of normal. However the wet ground prevented winter digging which did not get completed till March, delaying any early sowing and planting. This was followed by a very cool spring which was fine for the flowers which lasted a long time, but not so good for fruit trees. There was plenty of blossom on all the trees, but it was too cool for pollinating bees which were noticeably absent. Fruit set was zero on the pears and very poor on the cherry. The peach tree only managed one fruit even though I did daily hand pollination with a soft sable brush. Apples and plums flowered later so the crops were better but not as good as the previous year.
Then spring gave way to a brilliant summer, but August appeared and spoilt the show. It was cold, wet and the sun disappeared for a few weeks.
Outdoor fuchsias which, prior to August had put on a fantastic display, lost all their flowers, but then in September they reappeared and decided to keep flowering till the end of the year.
Another plant that seemed to thrive was my fig tree. Young embryonic fruit buds that normally fall off in winter, survived to produce my heaviest crop ever. Ripe figs all summer long was a major attraction. My small tree growing outdoors on my allotment plot produced nearly eighty ripe figs over two months.
The warm sunny dry summer (excluding August) suited all the soft fruit giving bumper harvests of currants, gooseberries, raspberries and strawberries. However that cold August really spoiled the grape harvest when the bunches were desperate for dry hot weather to ripen up and increase the sugar content. All grape wines had to have sugar added to give a decent alcohol level while they fermented in my demijohns.
The wet winter also gave rise to several disease epidemics. Clubroot which spreads in soil moisture devastated most brassicas that had not been bred for resistance,
as well as radish and wallflower. Phytophthora root rot introduced several years ago on infected raspberries, continues to affect woody perennials. Three new grape vines died out as well as my five year old goji which must have been old enough to give me my first berries. This disease is also spread in soil moisture. There are about ninety strains of phytophthora some of which are quite specific affecting raspberries as well as potatoes (blight), but some strains can affect a wide range of plants.
Rose blackspot was another problem after the wet August, but at least roses gave a great show in mid summer, then well into winter.
My mature Victoria plum tree, well over thirty years old became infected with silver leaf disease and will need to be removed, as there is no cure and the tree will die or produce no more plums.

Plant of the week

Tradescantia zebrina, the wandering Jew is a popular house plant. It likes a warm room with good light, but out of any direct sunlight. Water it sparingly in winter but freely in summer with an occasional feed.

FESTIVE THOUGHTS



FESTIVE THOUGHTS

Winter has truly arrived with snow frost and the December gales, but this year my new greenhouse is much stronger than the previous one, so I am confident it will be just fine. Under glass winter lettuce is still plentiful and my boxed up chrysanthemum stools all have short sturdy green shoots which will provide cuttings next March. Greenhouse temperatures have only just gone below freezing which is quite healthy. The Black Hamburg vines have now all lost their leaves so will get pruned within the next few weeks taking all growths back to one or two buds from the main rods.
Down on the allotment the digging has been held up by the wet weather though good progress was made every dry day when there was a wee bit of sun. One third of the plot has been turned over, but I still have a lot of land occupied with winter vegetables, permanent fruit bushes and my flower border. Other sections are down to a clover green manure which I will dig over in late winter.
Back home the garden was totally weeded in autumn, and leaves collected as they fell. Numerous spring bulbs are pushing through the soil surface with snowdrops showing the first flower buds just itching to open up on a sunny day. They don’t seem to mind whether it’s just December with most of the winter still to come.

Shrub pruning is still ongoing and roses usually get done on a sunny day in the heart of winter, when I have the urge to get outdoors but the ground may still be frozen over. However some roses are still flowering in competition with both hardy fuchsias and other fuchsias. One City Road plot holder has a row of Fuchsia Swingtime (or a hardy version of this variety) still in full bloom. An amazing sight as I would have expected the recent frosts to knock it back into dormancy.
As we head into the festive period, I suppose the allotment and garden will be fine without my attention for a couple of weeks, though I will still have to dig up a few swedes, a cabbage, some sprouts and leeks and parsnips and hope that my row of earthed up beetroot is just fine. Then there is still some winter rocket and other salad leaves to pick as well as kale and chard. There should be plenty of fresh veg. for Anna’s Christmas table, and I have ample bottles of home brew wine just waiting to be sampled. This year’s best ones are the gooseberry, aronia and apple, followed by the Saskatoon and red currant, though I still have to sample the Brant outdoor grape wine brewed just over two years ago. Wine making is an ongoing activity related to time of harvesting crops as well as availability of demijohns. Thus my 2014 apple crop is only now fermenting in the demijohns, but the blackcurrants, now in the freezer, won’t get brewed till late winter when I have some spare demijohns.
Outdoor gardening activities over may be curtailed over Christmas and New Year, but there is going to be some new landscape works in front of the house so time will be spent browsing through catalogues sorting out appropriate plants to buy in. Every year I buy in several new plants to try, most often fruit varieties, grapes or flowering shrubs, but then struggle to find a spare piece of land for them. I have to be ruthless and discard any plant that fails to impress. Many shrub roses had to be removed when they proved to be very prone to blackspot, however the very old variety Ispahan is quite tough and flowers profusely every year. Another old but very reliable rose is the white scented climber Mme Alfred Carrier. However its strength will have to be curtailed as my medium sized garden is struggling at it reaches beyond sixteen feet tall and sprawls a similar length in all directions.
 
Plant of the week

Holly (Ilex aquifolium) has been used as a festive decoration for hundreds of years even going back to the time of the Druids who used holly wreaths on their heads in winter celebrations. The holly tree, leaves and berries can be quite toxic, and birds normally leave them alone till they have had some frosts to soften the berries, though the City Road allotments resident blackbirds have had no trouble eating our plentiful supply of fresh grown holly berries.

PREPARE FOR WINTER



PREPARE FOR WINTER

A lot of people are under the impression that, as the days get shorter and colder with frequent frosty mornings, it is now time to forget about the garden till next spring. Unfortunately, the dormant season is a time to catch up on numerous tasks that seem to keep us outdoors on most sunny days and even those days when the ground is frozen or covered in snow.
The dormant season from November to March was traditionally the time to do all the new planting of trees, shrubs, roses, and many other plants that came as bare root plants. Today most plants are in pots so planting can be done just about all year round. However this time of year is best for soil cultivations incorporating manure or compost ahead of planting. This will also give the new planting a better chance of establishment as weeds will have been removed or dug in, then a mulch applied to retain moisture and prevent weeds from growing.

This is about the latest time for planting fresh strawberry runners for cropping next year.
I have always chosen a frosty day when the ground was frozen to carry out some tree, shrub and rose pruning. It never seems to do any harm. With bush roses I remove most wood except the strongest young shoots which get pruned by about half their length. Shrub roses just get straggling untidy shoots removed. Climbing roses get removal of all weak shoots, and some older wood and any shoots growing away from the wall or fences. Other shoots are lightly tipped and tied in.
With apple trees I try a bit of crown reduction on my mature trees to reduce the height so I don’t have to climb so high at harvesting time, as Anna’s nerves just can’t take it any more. I keep telling her good gardeners, well trained in fruit growing just don’t fall out of trees.
Well at least not very often. I only do a modest amount of spur pruning in winter as I prefer to regulate the balance of growth to fruiting wood, by removing the occasional large branch provided I can replace it with another younger shoot to take up its place.
Up on the allotment the autumn rasps and brambles have been pruned as well as my outdoor vine Phoenix, Solaris, Polo Muscat and Muscat Bleu. Prune greenhouse grapes in December to January.
Digging in compost continues as I try to complete all my soil cultivations by the end of this month.
Next year’s rotation plan is now completed, so I know where all the main crops will be going. That way I can add compost as digging proceeds according to the needs of each crop.
Land allocated for late planted crops such as sweet corn, courgettes, French beans and pumpkins will get sown down with a clover green manure crop in March, then dug in before planting.
I keep an eye on the weather forecast as my last row of beetroot is still perfect outdoors after getting some earthing up,
but if any severe frost threatens then I will lift them and store them indoors.
Outdoor water supplies have been turned off and drained and the pipes lagged for frost protection.
Keep a watch over stored apples and potatoes. Remove any apples going bad and keep shoots off stored potatoes. Gladioli and begonias should now be quite dry so they can be cleaned up and stored in some dry sand or soil in a frost free place till spring.
Now is a good time to complete taking of hardwood cuttings of shrubs and fruit bushes. They can be lined out in a prepared bed in a cold frame or in pots of well drained compost.
Put out bird feeders now, as once they have devoured all our berried trees and shrubs and the ground starts to freeze up their food source gets a wee bit restricted.

Plant of the week

Salix britzensis is a favourite willow for the coloured stem winter garden, where it is grown as a stooled bush. It has bright orange red stems all winter from leaf fall till the following March. It will start to grow then, but to keep it a bush it gets cut back to ground level. It will grow up to about eight foot tall. After cutting back in March I use the tall stems on the allotment to support my rows of peas.

PLANT SOME SHRUBS



PLANT SOME SHRUBS

Garden shrubs are just as essential to the landscape as is a lawn, trees, patio and paths. Everyone who has a garden no matter how small or large will at some time be considering  a bit of landscape planting for many different reasons, and when we move house to a new property or an established one we still want to create our own wee patch of heaven.
If the new garden is already well established by a previous owner, we need to assess what is there and what we want. Most often you will find several plants that are well worth retaining, so do not be in a rush to clear the site. However on a new built plot just vacated by the builders we will have a blank canvas to create our personal landscape to our own needs. There are many factors to consider so take plenty of time and work things out on paper before buying in the plants.

There are always your own personal “must have” shrubs to find a spot for. My personal choice includes the rhododendrons, azaleas and camellias, plus heathers for ground cover. Viburnums and honeysuckle gave me the scents and clematis and climbing roses gave me colour for tall fences.
I know of many impressive very small gardens who may only have one decent specimen shrub, but when it is in full bloom that garden comes alive even if only for a couple of weeks. For the bigger garden with room to grow a magnolia or philadelphus unpruned and allowed to mature it can make a fantastic specimen, but unfortunately too many people get nervous as it reaches ten feet or more and out comes the loppers.
Different parts of the garden will be sunny or shaded, sheltered or flat and in the open or adjacent to walls and fences so each area’s needs will be quite different. I always use all my south facing walls and fences for the more tender or exotic plants such as my outdoor grape vines, cherries and figs.
Shrubs can be used for screening along boundaries or around the compost heap and if an
impenetrable barrier is needed then use a pyracantha, rubus (mentioned below) or some of the very thorny shrub roses. Patio areas have their own needs for shelter from winds, privacy for sun bathing in summer and if possible use scented plants to create a pleasant environment.
Steep banks that are difficult to maintain can be planted with ground cover such as ivies, cotoneasters, hostas or heathers and if the ground is sunny and dry then use senecios, ceanothus, brooms, pinks, and cistus or rosemary and lavender. Some ground cover such as hypericum can also be underplanted with bulbs such as the stronger Darwin Hybrid tulips which will give a spring display of colour.
It is also a good idea to try and create strong impact in a range of places at different times by grouping those plants together that flower at the same time. Cistus flowering in early summer looks great with a background of the taller deep blue ceanothus.
Plants with good autumn colour can also be combined together to give an autumn display before all the leaves fall off. Deciduous azaleas, cotinus, the smoke bush, and dwarf maples will combine to brighten up the autumn display.
Similarly berried plants such as the cotoneasters, pyracanthas, pernettyas and berberis will provide food for small birds as well as being attractive in early winter.
Then for interest right through winter give thought to the coloured stemmed shrubs such as cornus, willow, kerria, rubus and some maples. They make an eye catching display right through to the end of March, when they then get pruned back to ground level. However the show can continue as they are quite happy to share the ground with spring flowering bulbs such as snowdrops, aconites, crocus, daffodils and tulips.
Shrubs can be planted from now right through till next March.



Plant of the week
Rubus cockburnianus is a very prickly white stemmed bramble growing to about six feet tall. It makes quite an impact in the winter garden growing alongside cornus, kerrias and salix. To maximise on the white stems it should be cut down to the ground at the end of March every year.

A COLD DAY ON THE PLOT



A COLD DAY ON THE PLOT

As autumn gives way to early winter we expect to find a few frosty mornings and maybe even the threat of some snow, but at this moment damp cold days predominate. It would be nice to crack on with the winter digging but the soil is often too wet to work on. However every time we get a dry sunny day there is always some job to tackle.
This year has been brilliant for beetroot and I have one complete row ready for picking, but we may get yet another mild winter, so I will leave the roots in the ground and just pick as I need them. The roots have been earthed up with some soil to protect them just in case we get any frost.
Autumn salad leaves and winter lettuce sown several weeks ago outdoors are now ready for cutting, but will last for months, hopefully. The greenhouse has also been planted with winter lettuce after removing the old tomato plants. The lettuce was planted at about nine inches apart and I have been using alternate plants for salads to give the remainder more room.
Back on the plot the winter vegetables are ready in abundance. Brussels sprout Crispin, a clubroot resistant variety is ready for picking, as is the swede Marion and winter cabbage Tundra. Leek Musselburgh and Parsnip White Gem add to the variety. However summer cabbage Kilaton, also clubroot resistant is still available and looks like it could last for another couple of months. It is quite difficult to use so much fresh produce when the freezer is still bursting with summer harvested fruit and vegetables. Kale is also at its best just now, and just perfect for soups and stir fries. Swiss chard is also a favourite for stir fries and other dishes.
When the soil surface is dry enough to walk on we can get on with the pruning of the autumn raspberries, the fig tree, outdoor grape vines, roses and the brambles. Other fruit was pruned in summer after fruiting as I wanted to gather as much pruning together as possible. We shred all our wood at City Road allotments then add the shreddings to the compost heap.
Next years seeds have been ordered as I need to plan the rotation. This allows me to know which areas to add compost to for digging in. The lions share goes to the heavy feeders such as peas, beans onions, leeks, sweet corn, courgettes, pumpkins and potatoes. Brassicas get a light cover of compost, but I can forget about the salads and root crops as long as they go on land that was well composted the previous year.
Digging is progressing on every dry day after spreading out the compost. I leave the soil as rough as possible to get weathered by frost, assuming we are to get some winter weather. Areas where clover and tares green manures are growing will be the last to get dug over. There is no rush to dig them in as the longer they grow the more the land will benefit from being broken up by the extensive roots. Nutrients will also not get leached out by winter rains and melting snow as the plant will absorb goodness from the soil as well as nitrogen from the atmosphere which is fixed into the root nodules. This is released back into the soil after digging the crop in and the plant rots down. These nutrients are then available for the next crop.
Sometime in mid winter on those areas where the brassicas are to be grown I spread lime to increase the soil alkalinity. Brassicas prefer a soil pH of about 7 or 7.5 to discourage the clubroot fungus. However do not lime freshly dug soil which has been manured or composted as it will react with the manure or compost and release nitrogen to the atmosphere.

Plant of the week
 
Cornus Westonbirt is one of the brightest red stemmed dogwoods. Grow it as a bush pruned every year at the end of March cut right down to ground level. My bushes grow up to four foot tall without any feeding or even mulching, but they would respond to this with taller shoots. Mix Cornus with other coloured stemmed plants such as Rubus cockburnianus, Salix britzensis and Kerria japonica to create a winter garden to brighten up the colder months. Underplant the bushes with spring flowering bulbs such as snowdrops and crocus to extend to colour into spring.
