THE NEW GARDENING YEAR HAS STARTED

                                THE NEW GARDENING YEAR HAS STARTED

Now that 2019 has passed and that very wet year is behind us we now look forward to 2020 hoping that a warmer and sunnier year is ahead. Yet again we seem to be having a mild winter, and half way through January the garden has not seen one snow flake. I always draw up a rough guide at the end of the last season of where the next crops are going in the following year so I can plan a rotation which I need so I can allocate garden compost to those crops that need the most. The peas, beans, onions, leeks, sweet corn, courgettes, pumpkins get a good helping, then the potatoes and brassicas also get some, but the root crops and salads are fine on land that was composted the previous year.
Time for a break on a sunny January

The first snowdrops are in flower and the aconites are not far behind. The wet December put a stop to the winter digging, but there were a few frosty days when it was ok to crack on with the digging, then
Greenhouse in January
in early January the strong gales dried up the surface just enough to allow digging without mud sticking to the wellies. My compost heap got emptied and a new one started. I was pleased that the winter digging session got completed by the middle of January. Other allotment plot gardeners were all on site getting the land sorted, erecting greenhouses, repairing fences, sheds and installing bed systems to help organise the plots. Our communal shed was busy as you always need a break from the graft and there is always someone putting on the kettle. It was brilliant to be sitting outdoors for a coffee break on a warm January day.
The short day length limits time spent outdoors, but we can always find a few indoor tasks. This is a
Potato Casa Blanca
great time to browse through new catalogues and see what new varieties of vegetables flowers and fruit we can try out. I try and get my seeds ordered by the end of January as some plants such as onions, broad beans and sweet peas get an early start. Last year the winter was so mild that my early seed sowing started in early February with onions and sweet peas, then I was taking chrysanthemum cuttings in mid February as there was plenty growth on the stools in my unheated greenhouse. I also started my begonias in mid February followed by broad beans and salads on a warm windowsill. February last year was so warm that I got my first early potatoes planted at the end of the month. That was a bonus as they were able to put on a lot of growth before the wet
Angels Trumpet
summer blight appeared. This year my first early potatoes, Casa Blanca are being chitted beside a window in a cool but bright room, as the sprouts are already growing though they are still quite stocky. Time will tell whether I can again get planting done by the end of February.
In the past I had always grown some Cape Gooseberries outdoors in a sheltered spot, but after a few wet, cold and dreich summers when ripening of the fruit was a problem I gave up on them. However this year I will try them again as they are a lovely fruit when we get a decent summer.
Cape Gooseberry painting
Another plant from the past that will get planted is the Brugmansia, also known as Angels Trumpets as I just love the scent, and they make a great dot plant in a large tub with other summer bedding plants around it. This flower is pollinated by night flying moths so the best scent comes in the evening, so best to use it on patios where you often relax on a
warm summers evening.
The greenhouse got tidied up after the tomato plants had finished and old plants removed and the grapes harvested. Once they had lost their leaves in December the vines got spur pruned back to the upright cordons. The borders then all got some compost and a light dressing of fertiliser and I planted a few plants of lettuce Lollo Rossa and some spring onions. This will give us some fresh salads over winter, but as we go into early spring the greenhouse will again be bursting at the seams as young growing plants fight for space.

Wee jobs to do this week

The Geraniums taken from autumn cuttings are now all rooted and beginning to put on growth. To
create short jointed plants grow them in a cool room with plenty light and remove any flowers as they appear. Also remove the tops to hold back growth and encourage a bushy plant.

DANGER IN THE GARDEN

                                                 DANGER IN THE GARDEN

I chose a career in horticulture as I just loved growing plants and enjoying the beauty of flowers, and it has only been lately that I discovered just how many garden plants contain toxins, poisons and skin irritants. In the early training years it was the Laburnum with beautiful golden yellow flowers followed on with poisonous seeds.
Laburnum vossii
Later on when hogweed became notorious we knew not to touch the sap or hairy stems. As kids we all got stung by nettles and were amazed that folk gathered the leaves to make tea. Growing up in St. Marys in Dundee we grew rhubarb (the poor mans fruit) and were well aware that we only ate the red stems and not the leaves. They are rich in oxalic acid, but no-one was ever tempted to stick the leaves in their mouth so there was no problem.
Dumb cane
Similarly the host of plant poisons is seldom a problem as there is little reason to eat something that would taste horrible. When looking into garden plants with poisons I was just amazed at the long list, (the Royal Horticultural Society has a list of over two hundred plants) and so many are our every day plants grown in gardens and house plants. Rhododendrons, daffodils, aconites outdoors and indoors we grow poinsettias at Christmas and forced hyacinths as well as dumb which if ingested can cause immobility of the mouth and tongue, difficulty in breathing and asphyxiation. Aconites have powerful toxin, aconitine, which can kill people who come into contact with it.  All parts of the plant are toxic but the sap in particular is a skin irritant, causing burning of the lips and mouth, vomiting, diarrhoea and spasms.
Winter aconites
cane
Over time plants have developed numerous ways to aid survival from thorns on stems to poisons in leaves, stems, bark, seeds, flowers and roots to discourage other animals from eating them.
Arisaema sikokianum
Outdoor public landscapes contain laurels, rhododendrons, snowberry and yew trees. Every part of the yew tree is poisonous The stems, leaves and seeds contain the toxic alkaloid taxine. Monks would use them to mark and protect the routes of their pilgrimages. They would collect the yew seeds as a food source and eat the aril, but spit out the seed as they travelled on their pilgrimages.
except the fleshy aril around the seed.
Brugmansia Angels Trumpets
Euphorbia griffithii Fireglow has a milky sap, which is extremely irritating to the skin and eyes.
Deadly nightshade
English Yew with berries
Arisaema sikokianum, an attractive bog plant produces fleshy seed coats contain oxalic acid in the sap. Opium poppies are quite commonly found in gardens brought in by birds, but the sap in the seed head contains opium. Another garden plant used in tubs to flower in summer is the Angels Trumpets, Datura stramonium. It has attractive large scented tubular white flowers, but every part of this plant is toxic. South American native Indians use it as a drug because of its hypnotic and hallucinogenic affects, but in the wrong dose it can be fatal. However to keep matter in perspective, very few folk suffer from plant poisons as we usually only eat those foods that we know and like, but then you find that some of our everyday foods contain poisons. Take apples, tomatoes and potatoes and look a bit deeper into their properties. We eat apples right down to the core which gets discarded. Just as well as apple seeds contain cyanogenic glycosides, a cyanide compound that could be fatal in high enough doses, but that means eating an awful lot of apples in one sitting. The potato and tomato belong to the solanacae family that contains some very poisonous members including the deadly nightshade. In the kitchen we all know to discard any potatoes where the skin has turned green on exposure to light. It contains the toxin glycoalkaloid solanine. This toxin is also present in tomato leaves, stems and unripe fruits as well as tobacco and peppers. These alkaloids in tobacco can be addictive and in belladonna fatal as it contains tropane.
Winter garden

Wee jobs to do this week

The winter garden has been the centre of attraction since early December once all the leaves dropped
to the ground. Cornus, Kerria, Salix Britzensis and the Japanese maple Acer Sangokaku have all got very brightly coloured stems, adding winter colour up to the end of March. However remove all the fallen leaves and any weeds that may spoil the show. This also lets the early snowdrops grow up into the light to add some colour contrast.

GROW FRUIT TO IMPRESS


                                                     GROW FRUIT TO IMPRESS


The dormant winter season is a great time to ponder the crops we will be growing in the year ahead. After a few years growing a wide range of normal fruit, flowers and vegetables most gardeners like to try something a wee bit different as we all like a challenge. Our allotment plots are not just areas to produce crops, as every time we get a bumper harvest someone will want to know what variety we are using and how did you grow it.
Harvesting the pumpkins
It could be a few rows of large onions, several massive pumpkins or a great crop of saskatoons. They all become talking points and add to the social life on the allotment as there is always someone
Aronia Viking
putting the kettle on and another pops into our communal hut with a few home made cakes. Looking back over the years my interest was always strongest with fruit. In the early fifties, as a wee laddie, I got introduced to raspberry picking on our local farm on the edge of St. Marys. Then in my early teens on my first allotment at Stirling Park on the Law hill I grew a row of Baldwin blackcurrants. A few years later at the Scottish Crops Research Institute where I studied weed control, one of the farm gardeners taught me how to graft apples.
Cherry Cherokee
As my gardening career took me south I got a job on a fruit farm in Pulborough in West Sussex growing blackcurrants, strawberries and apples. As I moved around the UK my garden was always used to experiment with fruit crops from growing early strawberries under tunnels, growing blueberries from seed and I continued to graft apples. My garden was not big so I needed to graft a few varieties on the same tree to give me early, mid season and late crops as well as a cooker, which was usually Bramley. However I am now back in Dundee with a fair sized garden and a decent allotment where I can indulge in my passion for growing fruit.
I now have an apple tree with six different varieties on it and a
Grape Brant outdoors
pear with five different varieties, and every year I find someone with a cracking variety I hadn’t seen before so I acquire some shoots for grafting in the spring, but I keep my Bramley tree separate. Breeders and nurseries have been busy and now you can get an upright apple, Starline Firedance perfect for small spaces and there is a wide range of stepover apples which form a low hedge with pruning.
I tried growing a peach outdoors but with no success due to peach leaf curl disease, but outdoor cherry Cherokee is fine, It gets blackfly, but just give it a spray and the birds are not such a problem as the fruits are so big the blackbirds just leave them alone.
Apple Starline Firedance
Growing strawberries in summer is very easy, but the challenge is to grow a few out of season, so I use an early variety, Mae or Christine and put it under a low polythene tunnel to crop from mid May onwards. The season is also extended with autumn fruiting Flamenco though the rains in 2019 wiped out most of the crop. For something different try a few Saskatoon fruit bushes or the chokeberry, Aronia Viking with black fruit extremely high in antioxidants.
Figs are another very impressive crop that seems to love growing outdoors in Scotland. They are very east to grow and crop for over a couple of months. Eat them fresh, but when crops are heavy they make an excellent jam and chutney.
Outdoor grapes can vary. Brant has never let me down, but last year Rondo and Regent just rotted in the wet weather. However they were great the previous year when we got a great summer. I will still keep them just in case better summers return. To grow successfully though, you need continual summer pruning of young shoots so the plant puts all its energy into producing large grapes.
Keep the birds well fed
Pumpkins are always a great challenge to get big fruits that ripen up to a brilliant orange colour, but select a good variety and keep the plants fed and watered if the season lacks rainfall.

Wee jobs to do this week

Keep bird tables topped up with seed, and clean tables and feeders regularly. On frosty mornings, replace frozen water dishes with fresh warm water. I no longer put out bread for the birds as it encourages pigeons and seagulls which are very messy.

THE NEW YEAR BEGINS


THE NEW YEAR BEGINS

The new year has just begun, so it’s a great time to plan the year ahead determined that 2020 will be better than 2019, so we can start off with good intentions. Climate change and global warming are constantly in the news, and the level of all my
Australian Bottlebrush
successes and failures in the garden have largely been due to weather. While it may be nice to see warmer weather in Scotland which would be great for my outdoor grapes and peaches, unfortunately it is accompanied with excessive rainfall, and our mild winters are also so damp that we cannot get on
Eucalyptus gunnii
the land to do our winter digging. However it is not just us gardeners that are suffering. Newspapers and television tell us about the problems of climate change on a global scale, so action is needed to play a part in trying to address the problem.  We now all understand the part trees play in absorbing carbon dioxide from the atmosphere and water from the soil and with energy from the sun they create food for the plants through photosynthesis in the green parts of leaves (the chlorophyll). Oxygen is given off as a bi-product which we need to breathe. However man has been removing trees all round the planet at an alarming rate for fuel, building materials and clearing land for crops. It is time to redress this imbalance on a global scale, but at the domestic level, gardeners can play a small part by planting a few more trees in their gardens. Although most houses today only come with very small gardens we can still find some trees for small sites. As it is leaf coverage that is important, even some shrubs will help to add to the green coverage for
Eucryphia Rostrevor
those with small gardens. I have seen some huge Berberis darwinnii, magnolias, rhododendrons, camellias and even my fig bushes have grown into wee trees.
Many trees now come in upright forms so do not require a lot of space. My favourite is the upright cherry, Prunus Amanogawa and Eucryphia Rostrevor with white flowers. There are also upright forms of hornbeam, oak and rowan trees. The dwarf cherry tree Prunus Shirotae has horizontal branches and is a mass of flowers in spring. Another tree form suitable for small gardens is weeping forms of birch, beech, lime, flowering cherry and ash. Then of course we have our local dwarf weeping elm, Ulmus camperdownii, first found in Camperdown Park by forester David Taylor in 1835 to 1840, but now all over the world.
I have grown the weeping birch, Betula pendula youngii from a small sapling,
Flowering cherry
but trained it up a tall stake for five years to give it a bit of height then removed the stake to let it weep. I now grow the white stemmed very impressive Betula jacquemontii, which makes a great specimen for the small garden. However in Scotland Rowans are a favourite and my orange berried Sorbus Joseph Rock puts on a great display of berries just loved by blackbirds and thrushes.
Mature fig tree Brown Turkey
Lilacs come in many varieties and the best hawthorn for small gardens is the Crataegus Pauls Scarlet. If you have a sheltered garden it is worth trying the Australian bottlebrush tree Callistemon citrinus. A hardy palm tree is also very impressive, but Cordyline australis can get cut back to ground level in a severe winter. Eucalyptus gunnii is another evergreen, but a wee bit hardier, though these two usually grow back again from the ground.
Gardeners on an allotment plot may wish to plant a fruiting tree of apple, plum, cherry or pear. We are spoiled for choice as there are so many, but where space is limited apples come as narrow columns in Starline Firedance and other come as low stepover forms, and for planting against a wall you can get a fan trained tree. Even our humble gardener with a small garden can still plant a tree in the fight against climate change.

Rose pot plant
Wee jobs to do this week

Pot plants bought in ahead of Christmas to add to the festive atmosphere such as poinsettias, orchids,

Christmas cactus, cyclamen, azaleas and potted roses can still be attractive for a few more weeks, so keep them watered and give them a wee feed to keep them happy. Grow them on in a light but cool room, though my red potted dwarf rose will be kept in a warm room as it has started to grow and I hope it continues to flower and stay dwarf. Time will tell.

REVIEW OF THE YEAR


                                                      REVIEW OF THE YEAR

The year is now just about behind us and we look forward to 2020 and wonder what lies ahead. There will be new varieties of fruit vegetables and flowers to try, but the biggest challenge is always the battle with the weather. It is a complete unknown as there is just no way of finding out which way it will go. We will all remember 2019 as a very wet year,
John and Anna wish everyone a Happy New Year
though records in some parts had it as very warm, but I cannot say I noticed any long dry very warm periods in Dundee, apart from a fortnight in the middle of May when summer arrived after a long cool spring. There was a great show of daffodils and tulips which went on for ages as cool weather
Apple Discovery
slowed down growth. The show of tulips has been the best ever, so a note was made to buy a lot more in autumn as the display created was worth every penny spent. I now use them for companion planting to enhance the show so I choose varieties to plant along with doronicum, forsythia, border phlox, saxifrages and amongst my roses. I use dwarf early varieties so there is no conflict for space and they die down before the roses need more room to grow. We had come through the normal mild winter to be followed by a cool but dry spring and plants were ready to get going. Seed potatoes went in very early. First early Casa Blanca went in the last week in February followed by all the others the first week in March. As shoots appeared through the earthed up furrows there was no late frosts to worry them.
The hose came out regularly in May as we went through a nice wee dry spell, but all was not rosy in
Dave's spring flowers
the garden. The mild winter was perfect for over wintering greenfly eggs and before long they arrived in plagues on roses, fruit bushes, lilies, pansies and the rosy leaf curling plum aphid wiped out all foliage on plum trees. The plum trees recovered by mid summer but nearly all of the fruit was lost. My outdoor peach tree Avalon Pride only produced one fruit, but it fell off before it ripened.  Apples and pears all fruited very well, but apple Oslin suffered from brown rot wiping out all that variety. Figs on the other hand gave great crops for nearly three months. The dry spell was perfect for the spread of mildew and blackspot smothering roses. The summer display was really severely reduced. It was not long, however, before the pleasant
Summer hanging basket
spring weather gave way to summer and the rain arrived. It forgot to go off. Wet mild weather is perfect for lettuce, cabbages, sprouts, kale and Swedes, but onions suffer badly as wet rot runs riot. However I had got my crop sown and planted early, so as soon as the rot began to spread they all got lifted and dried off. Strawberries also suffered from botrytis rotting a lot of the summer crop and the autumn crop, (Flamenco) which could have been a great crop but was wiped out by botrytis rotting all the fruit. Early strawberry Christine however started to fruit at the beginning of May, before the rains arrived and a good month ahead of last year. Many pumpkins and courgettes all rotted as they grew.
Brant Grapes at City Road Allotments
Although a wet year, garden flowers have all mostly done well. Lilies and garden pinks like a hot dry climate, but both put on a great show, in spite of heavy attacks of greenfly. Geraniums also flowered profusely especially those in hanging baskets.
Top Awards for allotments for John and Dave
Outdoor grapes varied. Brant excelled itself both on my house wall and up at City Road allotments, but rain rotted all fruit on Regent and Rondo. Greenhouse grapes Black Hamburg, Solaris and Siegerrebe all fruited well and most of the crop is now maturing away quietly in demijohns. Tomatoes were all good under glass, and my cherry tomato trial went very well with Supersweet 100 and Sungold both getting top marks for sweetness and cropping.
City Road Allotments won an award for the best allotment site in Dundee and I got the cup for the best plot in the town. New communal flower borders and outdoor grape trial against our south facing sheds may have caught the judge’s eye.
Euonymous needs pruning

Wee jobs to do this week

Shrubs grown for their impact of coloured foliage such as the Euonymous Emerald n Gold and
Emerald Gaiety provide great interest in winter, but once well established like to keep growing and spreading. However once they have filled their allotted space cut back any branches blocking paths.

FESTIVE THOUGHTS


                                                             FESTIVE THOUGHTS

As we enter the few days left in the run up to Christmas our thoughts may well turn to activities other than gardening. The Christmas decorations are everywhere and there is a wee Santa Claus looking out at every turn. The Christmas tree emerged from the attic, a bit dusty, but otherwise in good form, and the wee fairy for the top fitted on perfectly though after a few falls as her dress is now a wee bit dishevelled. We are strong believers in recycling
John looking over new catalogues
so our plastic Christmas tree of over thirty years is no bad going, and the tree lights are still in perfect working order.
However it is not possible to forget gardening duties entirely as there is watering of numerous pot plants and rooted cuttings in the greenhouse and numerous windowsills, and with every dry day I must return to the allotment to continue the winter digging. The year seems to want to end just as wet as it has been since early summer. There has been plenty well rotted garden compost to spread and dig in, as the growth year created an abundance of leaf growth which ends up in the compost heap. Autumn and early winter was surprisingly calm, so as leaves fell they all dropped onto the ground instead of blowing away. So again there was plenty for the compost heap. The fresh compost will have a few months to rot down and should be ready by late spring for digging into the areas for late planted heavy feeders such as courgettes, pumpkins and sweet corn.
Cotoneaster berries for the birds
Weird summer and autumn weather played havoc with early chrysanthemums. They were not early as most flowered in November, and grew nearly six feet tall, well above their supports so strong winds blew them over. Lifting the roots and boxing up ended up as a December task on a rare dry sunny day, so they are now under cover in the greenhouse.
Harvesting outdoor crops to keep the kitchen supplied with fresh vegetables continues, but it is difficult finding a dry day. There is plenty of sprouts, cabbage, kale, Swedes, leeks, winter lettuce, spring onions, parsnips and beetroot though the latter are a lot smaller than normal. I put this down to adjacent crops being so vigorous this year that they have all been fighting for room and the beetroot lost out.
Fresh harvested winter vegetables
Sprout buttons are suffering from attacks of mealy aphis so Anna has to remove a fair number of leaves, though we have huge crops this year. The fresh vegetables together with those in store and freezer will make us near self sufficient all winter, but I really miss my home grown cherry tomatoes produces totally free from any chemicals and grown in border soil so they all came with fantastic flavour and soft skins.
Garden produce in store
Although wet weather keeps us indoors it gives us time to watch the garden birds feeding in our feeders which we keep topped up. They seem to be having a time of great opulence as berried shrubs and trees are just laden with heavy crops from Cotoneasters to Rowans and even those few apples left on the tree after harvesting help the birds get a balanced diet. Berried trees and shrubs, winter flowers on Mahonia Charity and the coloured stems of Cornus and red maple Sango Kaku brighten up the garden in the winter months.
Back indoors the festive period is a great time to relax with a wee drop of three year old Saskatoon or
John completes painting of Arthurs Plot
gooseberry wine and browse over catalogues to see what new plants we can try next year. The allotment rotation plan for 2020 is in place but seed variety selection has still to be sorted out. I usually do a review of the previous year’s crops to drop failures, reorder the best ones, and add in some new fruit and vegetables. However I always have my other hobby of painting when the garden is out of bounds, but as I am painting a winter scene of Arthur’s Plot it is back to the allotment.

Wee jobs to do this week

Polythene lining around greenhouse
This year was one of great growth, so all my geraniums ended the season looking very healthy, so I will try and over winter them in my cold greenhouse, but to keep the cold out it will be lined with sheets of bubble polythene. This can be attached to the framework with plastic plugs which fit into channels in the glazing bars. I have left a few geraniums outdoors in a sheltered spot to see if they will survive if we get another mild winter.

FESTIVE GIFTS FOR GARDENERS


FESTIVE GIFTS FOR GARDENERS

We are now in December so it is very hard to avoid festive thoughts on the run up to Christmas, as we ponder what gifts do you get for the keen gardener. Although the keen gardener will have all the necessary tools to keep on top of the garden, things wear out, so check on those secateurs, loppers, and good garden gloves which never last too long.
White stemmed birch tree
Gift vouchers for garden centres or specialist nursery are favourite for chrysanthemums, begonias, raspberries, strawberries and other fruit trees and bushes. Then there is any amount of great house plants in flower to decorate the home and add that wee bit of festive luxury in addition to the essential Christmas tree. Several years ago a friend who knew I was into gardening, brought me ten sacks of horse manure. Now that was different and very welcome but they were not going under the Christmas tree with all the other gifts.
Supermarkets always get geared up for the festive trade, so a large poinsettia is essential, then I see great cyclamen, winter cherries, Christmas cactus, Phalaenopsis orchids, winter flowering azaleas and lovely Amaryllis. Another store had small pots of roses in full flower about nine inches high. This brought back a memory of my time in College in Chelmsford studying for my National Diploma way back in 1968. I did an experimental study for my dissertation on how to grow dwarf roses. College staff helped me sort out some dwarfing chemicals and I managed to produce a range of scented roses of Wendy Cussons taken from softwood cuttings. I was sure this skill was a winner and once I left collage it would make me a millionaire. Just look how the demand for pot mums took off assisted by dwarfing chemicals. Unfortunately I never had a greenhouse at that time so the pipe dream never got started. Dwarfing chemicals are still used to keep the red poinsettias down to a decent size, (they make small trees in native environment.) They last for several months, but in spring they will start to
Poinsettia
grow quite big so without access to chemicals they end up on the compost heap. However the dwarf azaleas and cyclamen can both be kept for several years, but grow them on in summer in cool shady conditions. Christmas cactus can also be kept for many years, but needs drying off after flowering. When it starts back into growth in spring start to water again but once it has put on some decent shoots it needs drying off again till early winter to ripen up the shoots when flower buds should appear once more.
Amaryllis is often given as a gift both in flower and as a dormant bulb. Pot up the bulb in a small pot leaving half the bulb below the surface and keep watered. After flowering keep it watered and fed
Pink orchid
then in late summer dry it off to let it go dormant before starting up again a few weeks before Christmas. Bowls of hyacinths and Paperwhite narcissi are popular gifts for the house at Christmas and both have a lovely perfume. After flowering plant them outdoors where they can grow and flower for a few more years. Phalaenopsis orchids are also a favourite and these will flower for many years. Some evergreen house plants make great gifts including dumb cane, Aloe Vera, the Cheese plant, the rubber tree and many others. The festive period is a great time to do a bit of goodwill to people, the
Cyclamen
environment and the planet so a gift of a young tree is a great idea to help out our carbon footprint as green leaves absorb carbon and add oxygen to the atmosphere. However make sure there is room for one. Trees come in all sizes and shapes and where room is restricted go for a columnar shape like the upright cherry, Prunus Amanogawa. Other smaller trees will include hazel, rowan, white stemmed birch, Japanese maple (Sango Kaku is a cracker) and the evergreen Cordyline australis, the cabbage palm. Fruiting trees are also popular especially apple (Starline Firedance), pear and plum and for the more exotic try a fig plant.

Wee jobs to do this week

Potting up rooted geranium cuttings
Geranium cuttings taken last October have rooted well and now need potting up as the young plants are starting to grow. Pot up into small pots and keep them on a windowsill in a cool room. If they have put on a bit of growth, pinch the top out to keep them stocky and encourage sideshoots. Remove all flower buds so plant can put all its energy into creating a strong plant, and do not overwater during the winter months.

A GOOD TIME FOR WINTER PRUNING


A GOOD TIME FOR WINTER PRUNING

Most of the autumn leaves have now fallen, and a few frosts towards the end of November have firmed up the soil, so now is the perfect time to start the winter pruning. Up at City Road allotments the timing of pruning is also related to the disposal of prunings. We have a large shredding machine so we make sure everything needing pruned
Cutting back the outdoor fuchsia
is done in one operation, so roses, fruit bushes, raspberries, apples and pears and even our grape vines all get chopped. We form teams who gather the prunings together then another team feed the wood
Climbing rose after pruning
into the shredder. The shredded material is great for paths, mulching, or adding to the compost heap. Nothing is wasted and it is great to see all our pruned branches get recycled back onto our plots. Wood chips used for paths will only last two years before it gets removed to the compost heap and a supply of fresh material brought in.
Raspberry pruned and tied in
Apples and pear pruning in the early years is all about building up a well balanced tree with an open centre then after a few years remove any diseased shoots, overcrowded centres, crossing branches and with pears some removal of those over vigorous shoots growing straight up without  any fruit on them. Do not prune plums in winter as it risks infection by silver leaf disease. Prune these in early summer.
Blackcurrant pruning is done to keep bushes young and remove older wood. Redcurrants are also pruned this way so no shoot is allowed to remain if it is older than three years. They readily push out new shoots from the centre, so try to keep about ten or so main shoots then do a bit of spur pruning to the remaining framework.
Rose bush pruned
Gooseberries have a tendency to bear heavy crops that bend down to ground level when full of fruit, so remove any low growing shoots and keep the centre of the bush open to make picking easier. Invicta is a great variety, but the spines are deadly when picking.
Saskatoons fruit on all wood so pruning is only needed to keep the bushes down to about five feet so they can be netted to keep the blackbirds away. I remove any tall shoots right down to ground level as they grow again from basal suckers.
Raspberries come as summer fruiting on canes grown the previous year, and autumn fruiting on canes grown in the same year. So for autumn fruiting cut everything down to the ground, but on the summer fruiting only cut out those canes that fruited last summer. New canes are thinned if growth has been
Spur pruned grape vine
prolific so that canes can be spaced about four inches apart when tied in to the top wire. Practise tying in with a running knot as this prevents the canes being blown to one side in gales.
Brambles are like summer fruiting raspberries. They fruit on long shoots grown the previous year. Remove all the old canes that have just fruited and tie in the new canes to fruit next year.
Shredding team at City road Allotments
Grape vines grown both under glass and in the open can be pruned in the same way. Establish a permanent framework of rods and spurs. The rods produce spurs every six to ten inches apart from which fruiting laterals grow, so prune from December to January by cutting all this growth back to one or two buds. Sap rises very early on vines so do not delay pruning beyond January otherwise the stems may bleed with rising sap. The Guyot system allows rods to be replaced every year.
Rose pruning of bushes and climbers are fairly similar in that we try and encourage new wood and cut out old wood, but it is difficult with climbers as they need older wood to climb up walls and fences. Remove weak and any diseased shoots and shorten back vigorous shoots by a third.
hardwood cuttings

Wee jobs to do this week

Now that all the deciduous shrubs have gone dormant it is a good time to propagate these with hardwood cuttings. This is an excellent way to propagate Cornus, Forsythia, Philadelphus and many other shrubs as well as currants and gooseberries. Take some of this year’s shoots about pencil thickness and about six inches long, cutting below a leaf joint and above a bud. Insert into a prepared bed of good garden soil with grit mixed in to aid drainage placing cuttings about four inches apart and half their length. A cold frame is also useful to give the cuttings some protection. They should be well rooted by this time next year.
