October

October is a yellow month, with the Field maples, hawthorns and above all elm hedgerows blazing brilliant yellow before falling.  It is an earthy time with the smells of fruit, wormcasts, fallen leaves and woodsmoke sifting through the afternoon air.

There comes a moment in October when you realise that the garden is running out of steam. I like the way that the season can shift almost overnight in October with soft days glowing with light and midday sun warm enough for shirtsleeves and then blasts of weather that send you huddling for warmth and shelter.

However good the weather, you cannot avoid the evidence that the garden is drifting steadily into winter. Every sunny day is borrowed. The light – although often the softest and most golden of the whole year – is slipping away.

Every second of light is precious because finally, on the last weekend of the month, the clocks change and a door closes tight until next spring.

Despite the way that light, colour and human and plant energy are all on the wane, it is time to take stock and to plan ahead. It is not so much a time to put the garden to bed but to gently prepare it for action. The more that you can get done between now and Christmas to prepare the garden for Spring, the better it will be for you and the garden.

AUTUMNAL BIRDLIFE AT LONGMEADOW

The whole relationship between the garden and birds changes as soon as the leaves start to drop. For a start they are more visible. They crowd the branches as a series of shapes rather than sound then the outline of a small tree will suddenly fragment as a flurry of birds leave scared away from grabbing berries whilst they can.

It makes you aware of how present the soft midsummer sound of unseen birdsong is, how important an element in any garden. Winter bird sound is much harsher, a series of warnings rather than melodious love songs. Occasionally a Robin will astonish the afternoon with a clear burst of song, but a November afternoon in this garden tends to shuffle with staccato bird sound, like overhearing an argument in another room.

You know when winter is round the corner when the Fieldfares and Redwings arrive from their summer quarters in Siberia. They are heralds of the season just as surely as summer is certified by the first swallow. But the swallows arrive with a kind of soaring familiarity, reforming intimacy with the garden and the precise details of the house like a child returning home after weeks away. Fieldfares (Turdus pilaris) on the other hand are a curious mixture of awkward truculence and shyness. They look like large thrushes with handsome grey head, chestnut back, black tail and spotted underparts but are always seen in flocks, whereas the resident song thrushes are much shyer, more solitary birds – and have a much sweeter song.

Fieldfares rise in a clucking, chattering cloud if you so much as appear within their sight and yet are always pushing aggressively forward as soon as they think your back is turned. Everything about them is harsh and jerky. Yet I like them. They are of the season. They like the apples left in the orchard best of all and will fiercely defend a tree with windfalls from other birds. They also do a lot of good for the gardener, eating snails, leatherjackets and caterpillars.

The other winter thrush, the Redwing, is smaller, daintier and less intrusive. Whereas the fieldfare has an instantly recognisable mauvey grey head, the Redwing is only really distinguishable from a song thrush in flight when the red flash under the wing is very visible – although its tendency to flock, like the fieldfare, is also a giveaway. In the dead of the country night, in an otherwise silent pitch blackness I sometimes hear their thin rather ghostly flight calls as they fly overhead.

What to do in the garden this month:

SCARIFY LAWNS

A bit of work on your lawns now will be repaid many times next spring. Start by raking it hard with a spring-tine wire rake. This will remove a surprising amount of thatch and moss which can be put on the compost heap. Do not worry about bare patches – if large a little seed can be sprinkled on them but otherwise they will fill naturally.

Then aerate it to remove compaction. On a small patch, a fork thrust in as deep as possible every 9-12 inches will do the trick but you can hire aerating machines for a larger lawn that remove small plugs of soil.

When you have finished, brush any plugs or loose soil across the surface and if it is very compacted, also brush sharp sand into the holes you have made. Don’t worry if it looks rough –  it will quickly recover in time to face whatever winter can offer and start next spring in the best possible condition.

•   If you do not already posses them, invest in horticultural fleece and some cloches. The point is that these are only useful if you have and employ them before you need them and there is no guarantee that there will not be a hard frost in October. Cloches are very good for rows of vegetables, keeping them dry as well as warm (although I always leave the ends open – happy to trade some heat for some ventilation) and fleece is the best temporary protection against frost, either laid out over small plants or draped over shrubs and bushes.

•   Keep deadheading throughout October, particularly the equatorial plants like dahlias. This will extend their flowering season and squeeze the last bloom from them.

•   Save yourself a fortune by collecting seeds from perennial plants, using paper (not polythene) bags. Always label seed packets immediately. Store in a cool, dry place until ready for sowing.

•   It is not too late to take cuttings and there is no more satisfying process in the garden if it is successful. Choose healthy non-flowering growth, use a sharp knife and very free draining compost (I use 50:50 sharp sand and sieved leaf mould) and keep the humidity high. Most things will strike now and overwinter successfully without needing potting on.

•   It is worth taking trouble to store the fruit so that it lasts as long as possible. Only store perfect apples, which discounts nearly all windfalls. A cellar is ideal or a cool garage, but polythene bags, folded not tied and punctured with pencil holes work very well. Put the bags somewhere cool, dark and dry.

•   You can plant or move deciduous trees, shrubs and hedges even if they are still in leaf as they have finished growing and the soil is still warm so the roots will begin to grow immediately. I once moved a 4 year-old, 20 metre long hornbeam hedge in October. It never batted an eyelid and grew away the following spring stronger than ever. It is essential, of course, to give them a really good soak when you do so and to repeat this weekly until the ground is really wet or the leaves have fallen. But if you are planting or moving a number of trees or shrubs  It is best to start with any evergreens before deciduous plants as they need to maximise root growth before winter kicks in.

•   Plant or move biennials such as forget-me-nots, wallflowers, foxgloves, onorpordums and mulleins. Dig up healthy Verbena bonariensis, cut back and pot up to use to take cuttings next spring and take cuttings of penstemons and salvias.

•  Continue planting spring bulbs but wait another month for tulips.

SOW SWEET PEAS

By sowing sweet peas in October you will have bigger plants with a stronger root system that should give flowers next spring earlier and last longer. But the disadvantage is that these young plants will need storing and some protection over winter if the weather is bad. So I sow some now and another batch in February and spread the risk.

I sow three seeds in a three-inch pot although root-trainers also do the job very well. Use a good potting rather than seed compost. Put them to germinate on a windowsill or greenhouse and once the first leaves have grown, place outside in a cold frame or protected spot. They only need protection from hard frosts, mice and becoming sodden, so do not provide any extra heat. They will be ready to plant out in April.

•   Cut back and compost all rotting foliage in the borders but leave as much winter structure as possible.

•   Start digging any ground that you want to replant this winter or use next spring. Doing it at this time of year means that it is accessible, dry and there is more daylight to do it in! But if this seems daunting do 30 minutes a week in two 15-minute sessions. Leave the soil in large slabs for the weather to break down over winter.

•   If you have raised beds – and if not October is an ideal month for making them – mulch them with an inch or so of garden compost as they become clear, leaving the worms to work it in ready for sowing or planting next spring.

•   Unless the weather is bad, most leaves do not start falling until November but gather them all and store every last one – nothing makes for a better soil conditioner or potting medium. If you do not have somewhere to store them sort this out early in the month. A simple bay made from four posts and chicken wire is ideal.

•   Sow ‘Aquadulce’ broad beans outside for an early harvest next May or June and sow sweet peas in pots and over-winter in a cold frame.

•   Keep cutting the grass for as long as it keeps growing, however it is better to have the grass too long than too short over the winter months. Rake out thatch and moss and add to the compost heap.

•   Cut off any hellebore leaves that are obviously diseased and mulch around spring-flowering perennials with a 50:50 mix of last year’s leaf mould and garden compost.

PRUNE CLIMBING ROSES

Climbing roses flower on shoots grown the same spring so they can be pruned hard now. (Rambling roses on the other hand produce their flowers on shoots grown the previous summer so should only be pruned immediately after flowering.) Start by removing any damaged or crossing growth or any very old wood which can be pruned right back to the ground. The main stems should be fanned out at an equidistance as horizontally as possible, tying them to wires or a trellis. Then all the side shoots growing from these main stems – which produced this year’s flowers – can be reduced to a short stub of a couple of leaves. The effect should be a tracery of largely horizontal growth with pruned side-shoots running along their length. Finally make sure it is all tied firmly in to avoid winter damage

•   We give our deciduous hedges – hornbeam, hawthorn and field maple – a light trim in October which keeps them crisp right through the winter and looks really good when everything else has sunk into decline.

Finally, and most importantly, get outside and relish every second of October sun. It will be a long time gone.

 

 

 

 

September

September is the month when everything in the garden thins out, as though the colours and light were being gently stretched and the leaves on the hedges gradually yellow and thin so the light drifts through them like smoke.

The sun noticeably drops in the sky, slanting at an angle that, for a few weeks, creates the best and most seductive light of the year.  The days are warm and the nights pleasantly cool and above all the light has a faded quality to it, as though thinned down and filtered through a cobweb.

However the colours remain strong and the Jewel Garden in particular can be at its best. Sunflowers, dahlias, cannas, tithonias, zinnias and cosmos all continue to fill the borders with splashes of bright, strong colour. In the Cottage Garden there is a last flurry of roses with the second, all-too-brief flowering.

The grass borders start to hide the magnificent stride – they will be at their very best next month – as the green foliage starts to become metallic and change colour to silvers, golds and bronzes.

The vegetable garden gives its most abundant harvest throughout September but with a sense, as the month draws to a close, that the productive year is ending too.

In all, this is one of my favourite times in the garden. Along with lots of good flowers and masses of ripening fruit and vegetables, the fading elegance gives it dignity and the knowledge that every fine day is one of the last makes them precious. It is a busy time too, with cuttings to be taken, seeds collected, much to harvest and hedge cutting to complete all before the weather turns.

 

FUNGI

There are times when fungus can be seen as a plague to blight the garden, spreading decay, collapse and horticultural disaster throughout the best kept border.

Yet the fields around Longmeadow are dotted with thousands of delicious field mushrooms and mushrooms are, of course, no more or less than the fruiting bodies of fungi and our hierarchy of ‘good’ and bad’ fungus is irrational.

In just one gram of soil – about a teaspoonful – you would expect to find around 10,000 species of fungi. All are part of the indescribably complex synthesis that enables plants to grow healthily.

Most fungi exist below the ground as mycelium that have wide-spreading filaments that feed on decomposing matter. So a ‘Fairy Ring’ in your lawn marks the extent of the mycelium growing outwards underground like the spokes of a bicycle wheel. The reason that the grass is greener and longer at the outer limit of the circle is that the fungus has used all the nutrients in the soil within the circle, whereas at the edge it excretes chemicals into the ground ahead to provide it with food and the grass temporarily responds by growing lusher.

Nearly 40% of the fungi in a healthy soil are vesicular arbuscular mycorrhyzae, known as VAM, which penetrate the cells of a plant’s roots and create a kind of living link between the root and the minerals and water in the soil.

Most fungi thrive in warm, damp conditions and global warming means that our mild autumns and winters and damp summers are making fungal ‘problems’ more common. There is truly nothing you can do to stop this happening. But ensuring plenty of ventilation, healthy plants and good soil drainage can help a great deal as well as celebrating the essential and unsung work that fungi are doing to help our gardens grow right under our feet.

What to do in the garden this month:

Some of the August jobs roll on into September. Above all continue to deadhead daily, cutting back spent blooms to the next leaf – even if that means taking off quite a long length of stem.

Carry on collecting seeds as they ripen – and before they disperse – and once really dry, store them in a jar or paper envelope (NOT a plastic bag) in the fridge until you are ready to use them.

Keep taking cuttings – in fact September is the very best month of all to take cuttings of shrubs like box, lavender, rosemary, as well as flowering plants like salvias and verbena. Always choose a healthy, straight shoot that is free from any flower buds (and this becomes increasingly hard to find as the month progresses) and always use a really free-draining compost or even pure perlite.

RIPENING TOMATOES

Tomatoes ripen best when the temperature is between 26 & 30 degrees so this summer was too hot for many of them – especially if grown under glass, and meant that many stayed green much longer than in a cooler summer. However by September the heat is running out and inevitably we are all left with green tomatoes that are never going to ripen. However if you pick them – either individually or on the bine, then put them in a drawer with a banana they will ripen and turn red.

SOW GRASS SEED/REPAIR LAWNS

This is an ideal time of year to either sow or turf new grass or to repair patches and worn areas on your lawn.

If it is just a worn area of thin grass, rake away all thatch and moss and remove all weeds and thinly scatter grass seed, watering well and keeping it damp. The seed should germinate and grow in days. Do not mow it for at least a month and if it looks unsightly going into winter, clip the new growth with shears.

For a larger area clean the edges with a sharp spade, fork it over to remove any compaction and either scatter with seed or cut a piece of turf to fit, making sure that the edges are butted tightly against the existing grass.

Like grass seed, it is important that turf should not be walked on or mown until growing vigorously, which will indicate that the roots have become established and are growing strongly. Depending on the weather, this may mean leaving it uncut until next spring.

AERATE LAWNS

Even if your lawn has come through this summer unscathed, it is always a good idea to aerate it at this time of year.

You can use a fork by working the tines into the ground at 12 inch intervals or, for a larger lawn, hire a rolling hollow-tine or slitter. Ideally this is followed by working sand into the holes they create with a stiff brush.

Finally give the grass a thorough scratch with a wire rake, to remove all the thatch and moss and whilst it will look a little threadbare this autumn, next spring your lawn will be rejuvenated for this autumnal working over.

APPLES

Start to pick over any apples at least once a week, checking to see if any are ripe by holding them in the palm of your hand and gently lifting and twisting to see if the stalk comes away easily. Do not force it, as when it is ready they always pick very easily.

If apples are to be stored successfully – and if carefully placed in a cool, dark fairly moist place they will keep for months – they must be picked without any bruises or blemishes and any windfall, however seemingly perfect, will not keep and should be eaten fresh or cooked and then frozen.

If you have more windfalls than you can possible eat or process, consider hiring an apple press to make juice which can then be bottled and stored.

PLANT BULBS IN POTS

Spring bulbs are now on sale but the ground is often much too hard to plant them in grass at this stage of the year, so I always begin by planting some bulbs in pots.

I start with crocus, daffodils – especially smaller ones like ‘tete a tete’ – reticulate irises, muscari and scillas. These need not be special or different from those in your borders or grass but will flower a little earlier and can be positioned to maximum effect next spring.

Choose an attractive pot which need not be deep – a terracotta pan is ideal –  and can be very small – a few crocus in a small pot can cheer the darkest February day. However,  you will need to mix your compost with some grit to make sure the drainage is good and the bulbs do not become waterlogged over winter. Place the planted pots in a sheltered position ready to move into the sun when new growth appears.

PLANT HARDNECK GARLIC

There are two types of garlic, hardneck and softneck. The type you mostly buy is softneck which has a plaitable stem, stores well (which is why shops stock it) and is often excellent. But the best, tastiest garlic is hardneck which has a stiff, upright stalk and because it is much harder to buy it makes sense to grow it yourself.

Hardneck varieties such as ‘Red Duke’, ‘Rocambole’, or ‘Early Purple Wight’ are slower to grow so should be planted now, a month or more before softneck varieties.

Like all garlic of any type, plant plump individual cloves (the bigger the clove the bigger the bulb it will generate) about 6 inches apart , pointed end up and buried a good inch below the surface in good but well-drained soil. Shoots will appear in about 6-8 weeks.

PRUNING SHRUB ROSES

I know that some gardeners are anxious about pruning roses but the many shrub varieties such as the gallicas, ‘english’ roses, albas or Hybrid Perpetuals are best simply trimmed with shears any time this month.

Do not worry about the position or angle of the cuts but clip away all long, straggly shoots as though you were trimming a hedge, leaved a compact, slightly domed bush that is about two thirds of its former size. In March, when you can see clearly without any foliage, you can inspect the shrub to remove any damaged or rubbing stems, but a simple shear in September is enough to keep it healthy and packed with flowers next year.

PRUNING SUMMER-FRUITING RASPBERRIES

The old brown canes of Summer-fruiting raspberries can now all be cut down to the ground, leaving the fresh new green canes standing. These new canes will carry next summer’s crop. It is a good idea to reduce these to the half dozen strongest shoots, taking out all smaller or awkwardly positioned growth. The remaining canes will need holding securely for the next year and therefore summer raspberries are best grown against a permanent system of support.

I tie the canes with twine to parallel wires fixed strongly between robust posts, weaving round them and fanning them out them evenly as I work along the wire at each level. It is important that it is really secure as winter winds can catch and damage them.
