Winter Planting Calendar – Garden Planting and Garden Care in Winter

planting calendar 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

Lawns

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.

Roses

Complete planting during mild weather. Begin to prune floribunda and hybrid tea roses in mild regions.

Perennials

Order plants and seeds for spring planting. Examine stored chrysanthemum stools for signs of rotting and withering; ventilate on mild, dry days.

Biennials

Keep overwintering plants free of leaves and debris. After severe frosts, firm any plants that have been loosened.

Bulbs

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 stored dahlia tubers for rotting or withering; if they are withering, soak in tepid water overnight. Plant hardy lilies when the soil is not too hard or waterlogged.

Fruit

Continue pruning fruit trees. 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.

Vegetables

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.

Flower colour

Christmas roses, Iris unguicularis, Viburnum grandiflorum, cotoneasters, winter-flowering heathers, hollies, winter-flowering jasmine, euonymus, Mahonia bealii, aucubas.


Mid and Late Winter Planting Calendar

Lawns

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 fuchsia. Prune winter-flowering shrubs once blooms are over; mulch and apply a general fertilizer. Cut suckers growing from the bases of trees.

Roses

Continue planting roses in suitable weather. Prune in mild or sheltered gardens.

Perennials

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.

Annuals

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.

Biennials

Dress with a general fertilizer. Lightly fork soil around them. Firm any plants that have been lifted by frost.

Bulbs

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.

Fruit

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.

Vegetables

Place cloches in position to warm soil for seeds sown in early spring. Outdoors, plant shallots. Feed winter brassicas with general fertilizer.

Herbs

Plant or divide chives, thyme, sage and mint Cut back frost-damaged sage.

Flower colour

Christmas rose, snowdrops, crocus, winter aconites, dog’s tooth violets, chionodoxa, Iris reticulata, lungwort, Prunus cerasifera, Viburnum burkwoodii and Viburnum tinus, Lonicera fragrantissima, winter sweet, dogwood, Chinese witch hazel, cornelian cherry.
