Make the Most of the Golden Weeks

Autumn is the busiest and most rewarding season in a British garden. The soil is still warm from summer, the air is cool and the plants are quietly winding down, which means the jobs you do now will settle in beautifully before winter arrives. Between the first fallen leaves in late September and the first proper frost, there is a window of a few weeks when tidying, pruning and planting all pay back twice over. Ignore it and you will spend March trying to catch up; use it well and you can spend spring simply enjoying what is already there.

The trick is to work in short, manageable sessions rather than planning one heroic weekend. An hour here and there, whenever the weather allows, is far kinder to your back and your motivation.

Clear Leaves Before They Smother the Lawn

Fallen leaves are the defining job of the season. On grass they block light and air, which encourages moss, worm casts and disease, so clear them little and often rather than letting them sit in damp, slimy drifts. A few minutes with a rake every few days is far easier than one marathon session in November.

• Lawns first. Rake or collect leaves weekly so the turf can breathe before winter.
• Borders second. A light scattering can be left and hoed in, but thick layers should be lifted from crowns of alpines, herbs and small perennials.
• Save the best. Oak, beech and hornbeam leaves make superb leaf mould. Fill black bin bags, punch a few holes, damp the contents, tie the tops and tuck them behind a shed for twelve months.
• Check your drains. Clear gutters, gullies and grates, and net a pond before leaves sink and rot.

Prune What's Dormant — and Leave What Isn't

Autumn and early winter suit plants that have finished flowering and are heading into dormancy. Start by removing the three Ds: dead, damaged and diseased wood. Then take out crossing or rubbing stems, and thin the centre of dense shrubs so light and air can move through. Cut back to a healthy, outward-facing bud, and always use sharp, clean secateurs.

Timing matters more than technique. Spring-flowering shrubs such as forsythia, lilac, philadelphus and weigela should be left alone now — prune them straight after flowering next year, or you will cut off the buds that would have given you your display. Japanese maples and birches bleed badly in spring, so if they need shaping, do it now while they are dormant. Cherries and plums are best pruned in summer to avoid silver leaf, so leave them well alone. Lavender only wants a light tidy in late summer; cutting hard into old wood now will leave bare patches that rarely regrow.

If you have room, this is also the perfect moment to take hardwood cuttings from currants, dogwoods and roses — push pencil-thick stems into a pot of gritty compost and forget about them until spring.

Plant Spring Bulbs in Layers

Nothing gives more pleasure for less effort than a border full of spring bulbs. Plant in generous drifts rather than neat rows, and use the simple rule of thumb: bury each bulb at roughly three times its own depth.

• Daffodils: 10–15cm deep, in bold clumps where you will see them from the kitchen window.
• Tulips: 15–20cm deep. November is ideal, as cold soil reduces the risk of tulip fire.
• Crocus, muscari and snowdrops: 5–8cm deep, planted close together for impact.

Containers are where autumn planting becomes really clever. Layer them like a lasagne: tulips at the bottom, daffodils in the middle, crocus on top. Cover with compost and a centimetre of grit to deter squirrels, water well and leave the pot outside. You will get weeks of colour from a single pot.

Feed Beds, Lawns and Soil

Mulching now, while the ground is still warm, is the single best thing you can do for soil structure. Spread 5cm of well-rotted manure or garden compost over empty beds, keeping it clear of stems and crowns so nothing rots. Do not dig or walk on heavy clay when it is wet — you will compact it into brick.

Give the lawn its final cut on a higher setting, then scarify lightly and spike it with a fork to improve drainage. An autumn feed low in nitrogen and high in potassium and phosphorus will strengthen roots without pushing soft growth that frost will destroy. Once a frost is forecast, stay off the grass entirely.

Protect Pots, Tools and Wildlife

Terracotta cracks in hard frost, so raise pots onto feet for drainage and wrap vulnerable containers in bubble wrap or hessian. Empty saucers so roots do not sit in freezing water, and move tender plants under cover.

Clean and oil your tools before storing them: sharpen secateurs, wipe blades with an oily rag, drain hoses and lag outdoor taps. Then, before you tidy too ruthlessly, remember that seedheads feed finches, hollow stems shelter insects and a leaf pile makes a home for hedgehogs. Check any bonfire before lighting it. A garden that is a little untidy at the edges in autumn is a garden that will be humming with life next year.
