Expert Garden Tips & Advice for October 2026 Sep 30

October is the month when autumn truly takes hold of the garden. After a record-breaking summer of extreme heat and prolonged drought, the return of rain through September has been a welcome relief — lawns are greening up again, the soil is softening and the garden is finally able to breathe. Now the trees are turning to shades of amber, gold and crimson, the air carries that unmistakable scent of damp leaves and woodsmoke, and there is a gentle, satisfying rhythm to the work ahead.

October is very much a month of planting and preparation. Spring bulbs, new trees and shrubs, hedging and the first bare-root plants all go into the ground now, while tender plants are brought to safety and the garden is readied for winter. Below are our exclusive Heritage Gardens gardening tips and advice for October 2026, provided by our own garden expert.

🍁 The October Garden — What to Expect

October brings a clear step down in temperature. Daytime highs across the UK typically range from 11°C to 16°C, with the south and west generally milder. Nights are longer and colder, and the first air frosts are likely in many areas during the month — earlier in the north, in Scotland and in low-lying frost pockets. October is also the month when Atlantic autumn storms tend to arrive, bringing strong winds and heavy rain, so check stakes, ties and structures early in the month.

Remember that the clocks go back on Sunday 25th October, so daylight in the evenings will become precious. Plan the bigger jobs for weekends and make the most of any dry, bright days. The good news is that soil temperatures remain relatively warm through October, particularly after such a hot summer, which makes this one of the very best months of the year for planting.

🌿 Lawns

• Finish autumn renovation — If you did not manage to scarify, aerate and overseed in September, there is still time in early October while the soil is warm and moist. After this summer's drought, most lawns will benefit enormously. Aim to have any overseeding completed by mid-October so the new grass has time to establish before the cold sets in.
• Autumn lawn feed — If not already applied, give the lawn a specialist autumn fertiliser low in nitrogen and high in potash. This toughens the grass for winter and helps it recover from summer stress.
• Mowing — Growth slows considerably this month. Continue to mow occasionally when the grass is dry, with the blades raised to around 4cm (1.5in). Avoid mowing when the lawn is wet or frosty, as this damages the grass and compacts the soil.
• Clear fallen leaves — Rake or blow leaves off the lawn at least once a week. A thick layer of wet leaves quickly starves the grass of light and encourages disease. Running the mower over thin layers of leaves on a high setting is a quick way to collect and shred them for the compost heap.
• Worm casts and moss — Brush away worm casts on dry days before mowing. If moss has crept in over the wet weeks of September, treat it now and rake out the dead moss a couple of weeks later.
• New lawns from turf — October is an excellent month for laying new turf. The ground is moist and warm, and the cooler air means far less watering is needed than in spring.

🌸 Borders, Flowers & Bulbs

• Keep planting spring bulbs — October is the peak month for bulb planting. Daffodils, crocus, alliums, muscari, fritillaries, snowdrops and hyacinths should all go in now, planted at around three times their own depth. Plant in generous drifts and groups rather than single rows for the most natural and impressive effect.
• Tulips — start at the end of the month — Tulips are best planted from late October into November, once the soil has cooled. This greatly reduces the risk of tulip fire, a fungal disease. Plant them a little deeper than other bulbs — around 15–20cm (6–8in) — which also helps them to flower reliably year after year.
• Lift and store dahlias — Once the first frost has blackened the foliage, cut the stems back to around 15cm (6in), lift the tubers carefully and leave them upside down for a few days to drain. Store in trays of dry compost or sand in a frost-free shed or garage. In milder southern gardens with free-draining soil, dahlias can be left in the ground under a thick 15cm mulch.
• Protect tender perennials — Bring pelargoniums, fuchsias, cannas, salvias and osteospermums into a greenhouse, conservatory or bright frost-free spot before the first hard frost. Cuttings taken earlier can be overwintered on a cool windowsill.
• Divide and replant perennials — There is still time to lift and divide congested clumps of herbaceous perennials while the soil is warm. Replant the healthy outer sections and water in well.
• Plant spring bedding — Wallflowers, forget-me-nots, bellis daisies, sweet williams and winter pansies can all be planted now for colour from late winter onwards. Interplant with tulips for a classic spring display.
• Selective tidying — Cut back perennials that have collapsed or become diseased, but leave ornamental grasses, sedums, echinacea and rudbeckia seed heads standing. They look magnificent when touched by frost and provide shelter and food for wildlife through the winter.

🌳 Trees, Shrubs, Roses & Climbers

• Prime planting time — October is arguably the best month of the year to plant trees, shrubs and hedging. Warm soil and plentiful rain encourage roots to establish over winter, giving plants a head start next spring. After this year's drought, autumn planting is especially worthwhile — plants established now will be far better equipped to cope with dry summers ahead.
• Bare-root season begins — The bare-root season for hedging, fruit trees and ornamental trees opens towards the end of October as plants become dormant. Bare-root roses follow from November. Prepare planting sites now by digging deeply and incorporating well-rotted manure or garden compost so everything is ready for planting.
• Roses — Reduce the height of tall bush and shrub roses by up to a third to prevent wind rock, which loosens the roots during autumn gales. Collect and dispose of fallen leaves affected by blackspot rather than composting them, to reduce disease next year. Main pruning is left until late winter.
• Move shrubs — If any shrubs are in the wrong place, October is an ideal time to move them. Dig out as large a root ball as possible, replant at the same depth and water in thoroughly.
• Check stakes and ties — Before the autumn storms arrive, check that tree stakes are secure and ties are not cutting into bark. Tie in the long stems of climbers and wall shrubs to prevent wind damage.
• Enjoy the autumn colour — Acers, Liquidambar, Cotinus, Amelanchier, Parrotia, Euonymus and Boston ivy will be at their fiery best this month. Take note of which plants perform well in your garden — October is a wonderful time to visit gardens and choose new trees for their autumn display.

🥦 The Kitchen Garden — Vegetables, Fruit & Herbs

• Harvest and store — Gather in the last of the apples, pears, squash, pumpkins, maincrop potatoes, carrots and beetroot. Store only perfect, unblemished fruit and vegetables — one bruised apple can spoil a whole tray. Wrap apples individually in newspaper and keep them in a cool, dark, frost-free place.
• Cure squash and pumpkins — Leave harvested squash in the sun for a week or two (or on a sunny windowsill) to harden their skins before storing. Well-cured winter squash will keep for many months.
• Plant garlic and onion sets — October is the ideal month to plant garlic cloves and autumn onion sets. Plant in a sunny, well-drained spot, garlic around 15cm (6in) apart with the tip just below the surface.
• Sow broad beans — Hardy varieties such as 'Aquadulce Claudia' can be sown outdoors from late October for an early crop next May and June. Autumn-sown plants are also less troubled by blackfly.
• Plant fruit — Container-grown fruit trees, currants, gooseberries and raspberry canes can be planted now. Bare-root fruit trees become available from late October into November.
• Clear, mulch and protect the soil — Clear finished crops, compost healthy material and cover bare soil with a thick mulch of compost or manure, or sow a green manure. Leaving soil bare over winter exposes it to heavy rain, which washes away nutrients and damages its structure.
• Herbs — Pot up parsley, chives and mint to bring onto a kitchen windowsill for fresh leaves through the winter. Protect Mediterranean herbs such as rosemary, thyme and sage from winter wet with good drainage.
• Pests to watch for — Slugs and snails thrive in mild, wet autumn weather — check under pots and debris regularly. Fit grease bands around the trunks of apple and pear trees now to trap winter moth caterpillars before they climb up to lay their eggs.

🪴 Pots, Containers & the Greenhouse

• Bulb lasagnes — Plant a "bulb lasagne" in a large pot for months of spring colour: tulips at the bottom, daffodils in the middle and crocus or muscari at the top, finished with winter pansies or violas on the surface.
• Autumn and winter containers — Refresh pots with heathers, cyclamen, skimmia, heucheras, ornamental grasses, winter pansies and trailing ivy for colour and texture right through the colder months.
• Protect pots from winter damage — Raise containers onto pot feet so they drain freely — waterlogged compost is far more likely to freeze and crack pots than dry compost. Group tender pots together against a sheltered house wall.
• Mediterranean plants — Olive trees and citrus plants in pots should be moved to a sheltered, sunny position. Citrus should be brought indoors or into a frost-free conservatory before temperatures fall below around 5°C. Reduce watering for both as growth slows.
• Clean the greenhouse — Once summer crops are cleared, wash down the glass and staging with a garden disinfectant to remove overwintering pests and diseases, and to let in maximum winter light. Check heaters are working before the first frosts.

🦔 Wildlife, Ponds & the Autumn Garden

• Make leaf mould — Fallen leaves are a gift, not a nuisance. Pack them into a simple wire-mesh cage or into black sacks with a few holes punched in them. In one to two years they will become rich, crumbly leaf mould — an excellent soil conditioner and mulch.
• Hedgehogs — Hedgehogs are preparing to hibernate this month. Always check bonfire piles before lighting — ideally build the pile on the day you intend to burn it. Leave a quiet corner with a log pile or heap of leaves as a winter refuge.
• Feed the birds — As natural food sources dwindle, keep bird feeders topped up with sunflower hearts, fat balls, nyjer seed and peanuts. Clean feeders and bird tables regularly to prevent the spread of disease, and keep bird baths filled with fresh water.
• Nest boxes — Autumn is the ideal time to clean out old nest boxes and put up new ones. Birds will use them for roosting over the winter and will be scouting for nesting sites early in the new year.
• Ponds — Keep a net over the pond to catch falling leaves, and clear it regularly. Cut back the dying foliage of marginal plants and remove pumps from small ponds to clean and store them over winter. Leave a ball floating on the surface to help prevent the whole pond freezing over later in the season.
• Clean and store tools — As the season winds down, clean, sharpen and oil tools before storing them in a dry place. Drain and store hoses, and insulate outdoor taps before the first hard frosts.
