September 2021 Garden Tips

Garden Notes for September 2021.

Watering plants is always a good topic of discussion. It is either too dry or it’s too wet. The essential thing is to try to get the right balance. When it is dry the closable leaf pores on plants (technically called ‘stomata’) shut down and slow down the process of photosynthesis. When there is enough water the stomata open, transpiration takes place, allowing the air containing carbon dioxide to go into the plant, which, together with sunlight, powers the reaction of water and carbon dioxide to make the sugars that are the plant’s energy source and building blocks. Watering keeps the stomata open in dry spells. As a rule of thumb one square metre of vegetation draws the equivalent of an inch of rainfall every day. Growth of plants in the summer normally requires additional irrigation. There are now numerous automatic systems that can be put in – especially for containers and hanging baskets.

The start of autumn means that many plants are producing seed heads, which we normally ‘dead head’ to keep the succession of flowers going. At this time it might be worth keeping them. With the cost of seed increasing year on year (the average cost is now around £2 per packet, and can be a lot more) it might be worthwhile considering saving some seed head for sowing. Flowers like Sweet William, Love-in-Mist (Nigella), Cosmos, or vegetables like Runner Beans, can be harvested just before the seed pod has fully dried. Use brown paper bags to hang the seed head upside down and store in a dry place. Remember to label the variety, and then when it is all nice and brown shake out the seed and you have saved yourself pounds for a few minutes work. Unfortunately the lovely hybrids that abound now will not breed true and you will have to rely on the expertise of the professional for that, but if you don’t mind a variety of colour in your Sweet William and so on it is fine.

Whilst the desirable seed heads should be kept, do watch out for all the weeds making sure that they survive. Milk Thistle, Shepherd’s Purse, Plantain and Groundsel- the list is endless, all should be removed before the flower has had time to set seed. I have been having a purge on Shepherd’s Purse that became rampant last year. It seems that no sooner than I have collected another bunch than an equal amount appears on another part of the vegetable garden. In a bit of land where I have a few fruiting trees there has been a huge crop of the weed called ‘henbane’ I have learnt my lesson in the past and have strimmed the area several times to stop the flower heads developing. It may keep them down but there are years of dormant seed just waiting for next spring and it will all start over again.
September is the best month to plant daffodils outside, so make sure you have ordered your new supplies. New varieties are always being offered, like ‘Easter Bonnet’ which has a white perianth and large pink cup. Then there is another one called ‘Petit Four’ which has an unusual cup that opens out into a ball of apricot.

Carrots should be lifted and stored before the roots start to split, which they will do very quickly once the heavy autumnal rains begin. Tomatoes should be cleared from the greenhouse so that it can be prepared for autumn and winter flowers. Onions should be dried and ripened off. In our uncertain weather it is a good idea to put them into a greenhouse or bench where there is plenty of air circulating before tying them up into ropes. Alternatively, use the mesh bags that are used in grocery stores. They need to be kept in the light and to have plenty of air round them, unlike potatoes that need to be stored in thick paper sacks with the light excluded.

August 2021 Garden Tips

Garden Notes for August 2021.

Laurel is a very useful plant but it is very vigorous and August is the month to keep it neat by trimming your laurel hedge. Some gardeners say that the laurel hedge should be trimmed using secaturs only. This does give a much improved finish, if you have the time. Using shears is much quicker and does not substantially make much difference. If you can allow your compost more than 2 years to compost, then put your laurel trimmings on to it. If, like me, you can only keep the compost heap for a matter of months, it is better to get rid of the laurel leaves since they take a long time to decompose due to their waxy surface.

Dahlias are supposed to be making a come back, having been rejected as being too gaudy. I have always liked them, and wish that I could grow specimens. To even have a chance to have the large blooms, now is the time to make sure that you disbud them, only one flower being kept on each stem. Dahlias will also need to be tied in as their stems become very heavy with the foliage and bloom and are easily broken by gusts of wind.

Cut out old raspberry canes that have fruited this year. Cut them down to ground level and retain only six or seven of the strongest new canes on each plant for fruiting next year. Overcrowding of the canes can lead to a higher incidence of disease.

Spring cabbage can be sown in the middle of the month; good varieties are Pixie, Flower of Spring or Wheeler’s Imperial. Onions that are reaching maturity should have their stems bent over and the bulbs partially lifted with a fork to encourage full ripening. Well ripened bulbs are much more likely to keep right through the winter.

If you have experienced an attack of potato blight, remember that outdoor tomatoes are vulnerable. In the past there were sprays but now it is impossible to get them so the best thing is to remove the affected foliage and burn it as soon as possible.

Planting up strawberry runners in the later part of August will help provide a good crop next year. If you are buying plants in, make sure that they are certified virus-free stock, as strawberries are very prone to virus disease.

Towards the end of the month, rambler roses that have finished flowering should be pruned. Disentangle the growth from the trellis (use gloves for this!) and cut out all the stems that have carried flowers. It is much easier to do this if you untie all the stems before you start the pruning. All the new stems made this year should be retained and tied back into place. You will really appreciate all the work you have done when they flower next year.

Plant Madonna lilies now, with not more than 2″ of soil above each bulb. Order lilies for autumn delivery. Tiger lilies and some hybrids produce bulbils between the leaves and the stem. Gather the bulbils when they fall at a touch and plant them in a deep seed box, about 2″ apart.

Keep shrubs tidy by dead heading. Especially roses, but do not apply rose fertiliser after the end of July, this avoids late soft growth which will not mature before winter.

July 2021 Garden Tips

Garden Notes for July 2021.

When roses have come to the end of their first glorious flush of blooms, try to give them a feed of a complete fertilizer as this will help with the second lot of blooms. Don’t forget to dead head them as well. Outdoor chrysanthemums will also need a feed, one with a high potash content to help the flowering process.

Early crops of new potatoes, early peas and broad beans will soon be finishing, make sure to clear away the top growth as soon as possible to make room for catchcrops such as the round carrots and beetroot. I have been planting radish in raised beds with a high compost ratio and have had lovely juicy radish within 5 to 6 weeks from sowing, just the thing to have a with a crisp lettuce cut from the garden.

Complete leek planting as soon as possible. Sow swede by the middle of the month. Lift shallots when their foliage has yellowed and turned over. Make sure to dry them out completely before storing.

Any flower heads that appear on spring-sown parsley should be removed as soon as possible as they will prevent leaf production which is what you want.

Dahlias need to be disbudded if you want top quality blooms. Keep an eye on them and feed with a fertiliser, as they are very hungry feeders.

If you have a problem with greenhouse ventilation that means you have to leave the main door open, and, as a result, you have unwanted visitors like sparrows and cats dust bathing in the soil, or attacking the plants, try putting up a door insect screen. They cost about £13 and are effective.

Early in the month dig up and divide dwarf and intermediate bearded irises if they have been undisturbed for 3 or more years. Tall bearded irises should be treated in a similar way towards the end of the month.

The best time for propagating many shrubs is at the back end of July. Cuttings of half ripened wood of shrubs like forsythia, ribes, escallonia and weigela can all be taken. Pull off the shoots with a heel of older wood, trim it neatly with a sharp knife and insert them into a box with sandy soil. Shade from bright sunshine, and next year you will have a whole lot more shrubs.

Do not cut the lawn too low, and wait for it to have sufficient length to provide a cut. Keep lawn edges trimmed.

June 2021 Garden Tips

Garden notes for June 2021

The pace of gardening really hots up in June, but it is still necessary to keep an eye on what the weather holds in store for us.

Frost susceptible, fast growing plants like dahlias, courgettes and so on should be put into their final homes assuming that there is no ground frost forecast. If it has been very dry, make sure that they have a good drink before and after planting them out. But don’t water them all the time. Give the roots time to settle down and then water (if necessary, and allowed) about once a week with a thorough soaking, preferably in the evening or early morning before the sun has got its full power switch on.

Hedges need regular attention now, and should be kept in shape, otherwise they can so easily get away from you making the task so much more difficult. Grass needs to be mown, but keep the cutter bar on a high level and the lawn will look greener for much longer. Do not put sprinklers on lawns, even if they do turn a dusty brown, as soon as the rain comes back they will recover with surprising speed. If you do water the lawn you are wasting a precious resource to no real effect.
On the subject of watering, make sure that your hose connections are working properly. Overtime the usual plastic based connectors become worn and/or damaged and should be replaced. I was looking for such a replacement and branded products in Garden Centres can be expensive. I found perfectly adequate ones in Lidl at a tenth of the price.

In the vegetable plot, make sure potatoes are kept ridged up, otherwise the tubers get exposed and ruined. Late Savoy cabbage can be sown now – use a variety like ‘Ormskirk’. Winter cabbage like January King should be planted out now. Leeks should be planted out using a dibber to make a hole about 6 to 8″ deep, and then water it in well.

Continue to make successional sowings of lettuce. Ones like ‘Tom Thumb’ ‘Little Gem’ and ‘Mini Green’ are fast growing, and the right size for many people. Webbs Wonderful is superb but rather large.

Early tomatoes should be ripening fast and the fruits should be picked regularly.

Roses are at their best towards the end of the month. It helps to keep them cut regularly and feed with a potash feed to keep them blooming longer. If you want to have specimen blooms it is advised to take out the side shoots carefully, as well as the smaller buds, leaving just one strong one at the end of the stem. Keep an eye out for pests and disease. Keep mildew at bay by regular spraying.

Suckers that sprout up from the base of damson and plum trees can become troublesome unless dealt with early on, so dig them out and burn the resulting twigs.

As alpine plants finish flowering, trim them back to keep the plants neat and compact. It will also encourage them to make good growth for next spring. Any gaps or vacant spots in the rock garden can be planted with summer flowering annuals or bedding plants to maintain the overall colour. Towards the end of the month cuttings can be taken from the alpine stock to increase the number of plants. Root the cuttings in a sandy compost.

May 2021 Garden Tips

Garden notes for May 2021

There is so much preparation to be done in May that it is easy to get carried away and be tempted to plant out too early. Garden Centres love this, as you will almost always have to go back and buy replacements for the plants that have died from the unpredictable ground and air frosts that can strike at any time during May.

One plant that can be put out, provided it is in a reasonably sheltered spot, is the outdoor flowering chrysanthemum. Possibly in this day of minimalism, stripped wood floors and stark furniture, the chrysanthemum may be regarded as being too gaudy. I love them. With care they reward you with so many beautiful flowers when everyone else is just going over. So plant these beauties now, make sure to plant them firmly and to make certain that the ball of soil rests at the bottom of the hole you have dug to put it in. Put a stake with each plant

Early Brussels sprouts can be planted out, and it is these that usually produce the best sprouts. Make sure to give them space, just under a metre (3′ in the old days), this way you will get a better crop. The space need not be wasted as you can inter-crop with early hearting cabbage, or early cauliflowers that will be harvested before the sprouts take up all the room. In May you should keeping sowing small quantities of lettuce for successional cropping. As the daytime temperatures increase in the summer it is more difficult to get good germination. It may be wise to invest in John Innes sowing compost. It is much more expensive than ordinary multi-purpose compost but you only have to use a small amount to start the seedlings and germination is considerably enhanced.

Start hardening off all those bedding plants you have bought from the internet or garden centre, by keeping them under a cold frame, or putting them out during the day and putting them back under shelter at night. Keep an eye out for watering, it is easy for them to become dried out in patches, especially if there is a wind blowing. Equally, do not over water, which can be just as bad, if not worse.

May is the time to sow hardy biennials – such as Sweet William, Canterbury bells, and Wallflowers. Sowing runner beans and French beans at the start of the month under glass gives them a good start and helps protect the young plant from the ravishes of slugs and snails. Don’t forget to sow the marrows and zuccini at the start of the month.

As alpine plants in the rock garden finish flowering, trim back the growth to keep the plants neat and compact. By doing this you will encourage them to make good growth for flowering next spring. In the same way flowering shrubs like philadelphus, deutzias and escallonias can be pruned as soon as their flowers fade to encourage new growth.

April 2021 Garden Tips

Garden Notes for April 2021.

I know that all the gardener advice is to cover over a patch of ground to warm up the soil and I should have done it a lot more than I have in the past. This season I did remember and have used a cheap polythene cloche that extends for about 10 metres. You can tell when the soil is warm enough when all the weeds start sprouting under it. As well as warming the soil it has also stopped it getting sodden with rain. The result is that I can really start salad crops like lettuce, radish and carrots this month, after getting rid of the weeds under the cloche.

Clematis varieties are popular. They are members of the Ranunculae, which are named after ‘Rana’ (the frog) and demand a cool moist root run. When planting remember that they need shade at the base so it is a good idea to put a piece of stone or paving over the top after you have planted them out.

April is the time to plant late flowering herbaceous plants such as kniphofias and michelmas daisies (Aster novi-belgii). Old clumps of taller rudbekias, helianthuses, monardas and heleniums will benefit from being split up in April since this will revitalise them, especially if they have been producing smaller flowers and losing their lower leaves in the previous season.

Plant onion sets and keep up a succession of salad crop sowings as the weather warms up towards the end of the month. April is the time to sow late summer cauliflower. If frost is forecast, cover up any potato foliage that might be showing. Make sowings of winter cabbage, purple-sprouting and spring-heading broccoli.

Don’t forget herbs. You can sow dill, fennel, hyssop, marjoram, rue and thyme. Parsley should be sown, allow time for it to germinate. Old fashioned gardeners used to keep a little bit of seed in a waistcoat pocket with a hole so it fell out as they gardened! (So they tell me).

If you have sweet peas they should be planted out now. If you are going to try and grow the larger specimens as cordons, start restricting growth by removing all tendrils and side shoots and remember to support them otherwise the slugs and snails will have a feast.

Towards the end of the month, if we have had dry weather, start to thin out salad crops like carrot. One tip is to water the row the night before so that it is easier to pull the roots out the next day.

Camellias will benefit from a top dressing of leaf mould. Remember to prune early flowering shrubs like berberis, forsythia, and spiraea immediately after flowering.

Do remember that early morning frosts are a real danger all through April and May, it is not until June, (and even then it can be a bit dicey for the first week!) that it is safe to put out any vulnerable plants – unless you can protect them at night.

YET MORE CANCELLATIONS ………………. OUR SUMMER SHOW

Most disappointingly, after numerous Committee Meetings, the decision has been taken not to run the Capel Show again until August 2022. Despite the government’s plan to lift all restrictions from 21 June, the uncertainty of both future government policy and the very nature of the path COVID takes really left little alternative. Of paramount importance is the safety and well being of all those involved with the show as well as our villagers and visitors from further afield. Whilst we are desperate to bring some normality back to the life of our community, we feel it prudent to wait a while longer.

Do keep growing your splendid fruit, flowers and vegetables. Even if they cannot be exhibited at the show they will certainly be enjoyed at the table or in the garden. Take a few minutes to read Sally Griffin’s gardening column in the Capel Magazine and keep an eye on this website, especially for Chris’s Tips – a monthly guide to what to do in the garden. We may also be able to arrange some talks later in the year and details will, in due course, be found here.

COVID Cancellations

We are truly saddened to advise that this year there will be no Spring Show or Plant Sale. We have debated long and hard the possibility of running these events in a different format and come to the conclusion that we can neither do so safely or within the bounds of the law. Looking ahead to 2022 we fully intend to return to organising these popular village occasions.

Capel Crocuses

Over the past years the Society has planted daffodils on the verges throughout the village. Last autumn members got together and planted crocuses on the green opposite The Old Forge Surgery. We hope everybody is enjoying the results in the spring sunshine.
