Winter Planting Calendar – Garden Planting and Garden Care in Winter
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 Winter and suggests plants to provide colour throughout the year.
Early Winter Planting Calendar
During mild spells, prepare sites for spring sowing. In dry weather lightly rake established lawns to remove dead leaves and scatter wormcasts. Aerate badly drained areas. Apply mosskiller if necessary.
Trees and shrubs
Continue planting deciduous species during mild spells; otherwise heel in young plants until conditions improve. Take hardwood cuttings if you haven’t already done so. Firm shrubs loosened by wind and stake if necessary. Remove dead, diseased and untidy branches.
Complete planting during mild weather. Begin to prune floribunda and hybrid teain mild regions.
Order plants and seeds for spring planting. Examine stored chrysanthemum stools for signs of rotting and withering; ventilate on mild, dry days.
Keep overwintering plants free of leaves and debris. After severe frosts, firm any plants that have been loosened.
Move potted daffodil, hyacinth and tulip bulbs with shoots into the house or put them in a cool greenhouse. Make sure they do not dry out. Frequently check storedtubers for rotting or withering; if they are withering, soak in tepid water overnight. Plant hardy when the is not too hard or .
Continue. Spray them with winter wash to kill moss, lichen and overwintering pests. Protect buds on fruit bushes with bird repellant — if the bushes are in a fruit cage this is not necessary. Feed and mulch red, white and black currant bushes. Look out for big bud mite on black currant bushes; remove infested buds and burn. Force rhubarb by putting crowns lifted in late autumn in boxes of moist compost.
Continue to dig the ground, incorporating well-rotted manure where root crops are not to be cultivated. Harvest cauliflowers, Brussels sprouts, parsnips, leeks, celery and winter cabbages. Place cloches over winter lettuces, and over some of the spring cabbages for an early crop.
Christmas roses, Iris unguicularis, Viburnum grandiflorum, cotoneasters, winter-flowering heathers, hollies, winter-flowering jasmine,, Mahonia bealii, aucubas.
Mid and Late Winter Planting Calendar
Turf new lawns. Treat established lawns with mosskiller.
Trees and shrubs
If the soil is not frozen, plant deciduous species. Prune deciduous summer-flowering shrubs such as clematis, buddleia, potentilla and hardy. Prune winter-flowering shrubs once blooms are over; mulch and apply a general fertilizer. Cut suckers growing from the bases of trees.
Continue planting roses in suitable weather. Prune in mild or sheltered gardens.
Lift and divide lupins, Michaelmas daisies, delphiniums, and any other hardy border plants that have been left for three years. Apply general fertilizer to other hardy perennials Firm plants lifted by frost. Fork over the soil between plants. Examine stored chrysanthemum stools for signs of rotting. Ventilate on sunny days.
In suitable weather dig and manure sites for sowing. Lightly fork over ground dug in autumn and work in a general fertilizer if it wasn’t manured. Sow half-hardy annuals in a cold frame or greenhouse late in the winter.
Dress with a general fertilizer. Lightly fork soil around them. Firm any plants that have been lifted by frost.
Deter birds from eating crocus buds by stretching dark cotton, supported on sticks, across the area occupied by the bulbs. Spray stored dahlia tubers showing signs of mould. Pot lily bulbs for early display indoors or under glass.
Plant fruit trees and bushes in mild spells. Feed all fruit trees with fertilizer. Every third year, paint tar oil wash on apple and pear trees. Prune raspberries, gooseberries and red and white currants. Prepare beds for rhubarb crowns and plant.
Place cloches in position to warm soil for seeds sown in early spring. Outdoors, plant shallots. Feed winter brassicas with general fertilizer.
Plant or divide chives, thyme, sage and mint Cut back frost-damaged sage.
