Garden Planting and Garden Care in Autumn
Container-grown plants can be planted at any time of year — but what about bulbs and seeds? Which are the best months to prune, feed or mulch? This calendar pinpoints the essential tasks of Autumn and suggests plants to provide colour throughout the year.
Early Autumn Planting Calendar
Sow new lawns before the start of the cold weather; re-sow worn areas. Aerate and top-dress existing lawns. Mow with blades set at medium height.
Trees and shrubs
Plant or transplant all types of evergreen trees or shrubs apart from conifers. After gales, check climbers and young trees are still secure.
Dead-head to encourage late. Tie in new shoots on climbers, and watch for diseases.
Dead-head and cut down all dead stems. Move late-floweringto greenhouse and dig up stools of early types and put in cold frame. Plant young hardy border carnations.
Clear away annuals that have finished flowering.
Plant out biennials grown from seed in separate beds.
Plant spring-: narcissi, anemones, scillas, grape hyacinths, Dutch, English and Spanish irises. Pot indoor bulbs such as prepared hyacinths, and tulips for flowering in winter and spring. Water dahlias in dry spells.
Prepare ground for winter planting of fruit trees and bushes. Prune any secondary growth on apple and pear trees. Cut away dead wood on sweet cherry trees and shorten the shoots pinched back in early summer Vegetables Sow winter lettuces and spring cabbages. Lift onions and ripen off under glass. Pickand runner beans. Earth up trench-blanching celery again. Feed leeks again with general garden fertilizer. Spray Brussels sprouts, Savoy and winter cabbages, cauliflowers and broccoli against caterpillars and cabbage whitefly. Encourage the last to ripen by removing some of the leaves on the plants. Continue digging up maincrop potatoes. Remove greenhouse shading and reduce ventilation.
Outdoors, plant rue and thyme and sow angelica and lovage. Gather fennel seed heads for drying. Under glass sow summer savory. Root sage cuttings in a cold frame.
Flower, leaf and berry colour
Dahlias, agapanthus, gladioli, Japanese anemones, golden rod, crocosmia, autumn cyclamen, colchicums, sedum, autumn snowflake, tamarisk, caryopteris, mountain ash, hawthorn.
Mid Autumn Planting Calendar
Lay turf for new lawns. Apply weedkiller on established lawns. Increase height of mower blades for cutting. Keep lawn clear of debris. Top-dress with sand.
Trees and shrubs
Plant deciduous and evergreen shrubs and trees (not conifers); protect in exposed sites with plastic sheeting and canes. Prune conifers. Take hardwood cuttings of all shrubs.
Plant at end of month. Take cuttings of species, ramblers, and some floribunda. Perennials Tidy borders, cut back plants and remove old stems and leaves. Divide and replant overgrown perennials that have finished flowering. Scatter slug pellets before slugs start laying eggs. Lift stools of outdoor-flowering chrysanthemums and store in boxes of old in cold frames or . Bring in other tender plants.
Finish clearing annuals. Biennials Complete planting of forget-me-nots, wallflowers, pansies, Canterbury bells and sweet Williams
Continue planting spring-flowering bulbs such as snowdrops, Iris reticulata, miniature daffodils, crocus and chionodoxa. Tulips can be left until late autumn Divide overgrown clumps of; cut off stems when they begin to fade. Feed bearded irises with potash. Cut down dahlias, lift tubers and store. Cut down stems of gladioli, lift, and store in a frost-free place.
Start planting new fruit bushes and trees. Take hardwood cuttings of gooseberries. Vegetables Sow more winter lettuces. Cover carrots sown in late summer with cloches. Feed Brussels sprouts and winter cabbages. Draw soil up stems of Brussels sprouts. Pick off yellowing leaves of cabbages. Gather last runner beans andbefore the frosts set in and clear away plants. Lift last of main-crop potatoes. Dig up maincrop carrots, swedes and turnips. Fumigate greenhouses.
Raise new plants of lemon balm by division. Plant tarragon. For a winter supply, sow chervil under glass and pot some roots of mint, placing them in a sunny window.
Flower, leaf and berry colour
Colchicums, nerines, Amaryllis belladonna, Michaelmas daisies, maples, strawberry trees,, Japanese quinces, sumachs, smoke trees, ornamental cherries, Virginia creeper.
Late Early Autumn Planting Calendar
Make one final cut with blades set high and apply fertilizer. Top-dress with sand. Rake to keep clear of dead leaves. Avoid walking on frozen lawns — the grass can become damaged. Laying turf is still possible, weather and soil permitting.
Trees and shrubs
Continue planting deciduous shrubs and trees. In cold gardens give winter protection to tender shrubs. If it is particularly cold, bring container shrubs indoors. Take hardwood cuttings.
Prune. Plant new roses as soon as they arrive. Take cuttings. Perennials Plant and divide perennials. Remove remaining weeds from borders. Protect perennials in exposed sites and any plants that are slightly tender by covering with straw or newspaper. Place cloches over Christmas roses to encourage early flowering. Ventilate stored chrysanthemum stools in cold frames unless the weather is freezing; keep the stools just moist.
Keep plants free of wet leaves.
Plant tulips, lily-of-the-valley and hardy lilies. Cover nerine bulbs with a thick layer of straw or leaves to protect them from winter frost. Examine bulbs potted in early autumn for indoor display. Move those with 2.5cm (lin) high shoots to a cool room, cold frame or greenhouse. Keep compost just moist. Examine storedtubers for signs of rot.
Continue planting fruit trees and bushes. Prune apples and pear trees before cold weather sets in. Prune red and white currants. Begin forcing rhubarb by lifting one or two plants and exposing their roots to frost to make the plants dormant.
Dig soil, and leave in large clods, to be broken up by frost. Incorporate well-rotted manure where no root crops will be planted. In mild areas sow broad beans and round-seeded peas for late spring crop. Check maincrop potatoes in store and remove any diseased ones. Keep greenhouse glass clean. Herbs Sow chervil under glass for a winter supply. Cover late-sown parsley and chervil with cloches. Bring bay trees growing in containers inside during cold spells.
Flower, Leaf and berry colour
Chinese lanterns, mountain ash, Skimmia japonica, pyracanthas, barberries, pernettyas, viburnums, snowberries, Vitis coignetiae.
