Spring Planting Calendar – Garden Planting and Garden Care in Spring

planting calendar spring 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 Spring and suggests plants to provide colour throughout the year.


Early Spring Planting Calendar

Lawns

Rake vigorously and mow with blades set high. Spike badly drained lawns and brush sandy compost into the holes. Feed lawn to help grass recover from winter and apply mosskiller if this wasn’t done in late winter. At end of month sow grass seed for new lawns. Turf can still be laid but it must be watered well to prevent shrinking

Trees and shrubs

Continue to prune winter-flowering shrubs as the blooms fade, and also species flowering in late summer Mulch with garden compost or bark and apply a dressing of general fertilizer. Remove winter protection from tender shrubs. Keep weeds between shrubs and under hedges under control with a hoe or weedkiller. Plant or transplant conifers.

Roses

Prune established plants, then spray branches and surrounding soil with a fungicide to destroy any overwintering spores. Feed with a rose fertilizer and mulch with garden compost or manure at end of month. Perennials Fertilize beds and apply a thick mulch. Finish dividing and replanting established plants. Remove winter protection from tender perennials Towards end of month, when the weather is mild and the soil drier, plant out perennials Propagate summer-flowering chrysanthemums from new shoots on the stools (root clumps) stored over winter in a frost-free place.

Annuals

Finish preparing the ground for seeds. Allow a couple of weeks for the soil to settle and then sow hardy annuals. Scatter slug pellets. Sow half-hardy annuals under glass for planting out in early summer Start begonia tubers into growth in boxes of moist compost with gentle bottom heat.

Bulbs

Dead-head spring-flowering bulbs. Towards the end of the month plant gladioli and acidantheras in succession. In cold areas plant De Caen anemones for summer flowering. Divide snowdrops. Remove dead leaves of bearded irisis and apply fertilizer to soil around the plants. Plant hardy indoor bulbs that have finished flowering outside, discarding those grown in bulb fibre. Place cloches over young lily shoots to protect from frost. Spread a light mulch of leaf-mould or well-rotted compost over beds of lilies.

Fruit

Finish planting fruit trees and bushes — only container-grown ones can be planted after early spring. Prune acid cherry trees. Fertilize apples, cherries, peaches and pears; also red, white and black currants, gooseberries and raspberries. Mulch both fruit trees and bushes to keep the soil moist and free of weeds.

Vegetables

Sow first vegetable seeds under cloches: onions, broad beans, parsnips, radishes, lettuces, carrots, round-seeded peas. In prepared seed bed sow cauliflowers, Brussels sprouts, broccoli and cabbages for later transplanting to a permanent site. Plant shallots and early potatoes. Scatter slug pellets among young plants.

Herbs

Sow salad burnet, chervil, common fennel, dill, lovage, marjoram, parsley, rosemary, sage and thyme. Plant bay trees and tarragon.

Flower colour

Dutch and species crocus, Iris reticulata, polyanthus, saxifrage, anemone, primrose, spring snowflake, Tulipa kaufmanniana, forsythia, camellia, flowering currant, Japanese quince, Daphne mezereum. Hyacinths and Maenolia stellata.


Mid Spring Planting Calendar

Lawns

Continue to sow grass seed for new lawns. Mow established lawns with blades set at medium height. Apply a fertilizer, followed two weeks later by a selective weedkiller

Trees and shrubs

Plant and transplant evergreen trees — especially conifers — and shrubs. As soon as flowering is over, prune forsythia, flowering currant and other spring-flowering shrubs. Lightly shear winter heathers. Cut back any frost-damaged hebes. Continue to mulch shrubs and trees with forest bark, well-rotted manure, compost or leaf-mould.

Roses

Apply mulch of manure/leaf compost. Perennials Sow perennials in a seed bed for flowering the following year. Prepare ground for outdoor-flowering chrysanthemums

Annuals

Complete sowing of hardy and half-hardy annuals. Plant out sweet peas.

Bulbs

Continue planting summer-flowering bulbs such as gladioli and acidantheras. Dead-head early flowering bulbs. Stake tall lilies as flower buds form. At the end of the month plant out dahlia tubers in mild areas. Fruit Spray pear and apple trees before they are fully in blossom with a combined insecticide/fungicide. Spray strawberries and raspberries with insecticide and gooseberries with fungicide. Water all fruit trees and bushes which were planted during the winter. Apply fertilizer to fruit bushes. Mulch established raspberries.

Vegetables

Remove cloches from seeds sown the previous month (onions, broad beans, parsnips, radishes, lettuces, carrots and round-seeded peas). Sow more of these vegetable seeds to ensure a steady supply through the summer months, and also start sowing spinach, summer, autumn and Savoy cabbages and sprouting broccoli. Finish planting early potatoes. Plant onion sets and main-crop potatoes. Under glass, sow ridge cucumbers and outdoor varieties of tomato. Also sow celery and French beans.

Herbs

Sow parsley, lemon balm, borage, chervil, coriander, dill, pot marjoram and sage. Plant bay trees.

Flower colour

Daffodils, tulips, grape hyacinths, lily-of-the-valley, wood anemones, aubretia, alyssum, arabis, gentians, brooms, magnolias, ornamental crab apples, barberries and spiraeas.


Late Spring Planting Calendar

Lawns

Mow at least once a week. Feed poorly growing grass. Apply a selective weedkiller. Trees and shrubs Prune brooms, weigelas and other spring-flowering shrubs that have finished blooming. Mulch trees and shrubs if you have not already done so.

Roses

Regularly spray against greenfly, mildew and blackspot. Apply a rose fertilizer. Perennials Weed borders regularly. Provide support for tall plants such as delphiniums and sea holly. Pinch out growing tips of Michaelmas daisies, golden rod, heleniums and other vigorous plants. Plant outdoor-flowering chrysanthemums early in month; remove centre tip a week later to encourage bushy growth.

Annuals

Plant out half-hardy annuals after risk of frost has passed. Thin seedlings of hardy annuals.

Biennials

Sow Canterbury bells, foxgloves, sweet Williams and wallflowers.

Bulbs

If space is needed, lift bulbs which have finished flowering.

Fruit

Place straw or spread black polythene around strawberry plants, and put netting over them to keep off the birds. Prune leading shoots on apple and pear trees.

Vegetables

Continue to keep a check on weeds with a hoe or weedkiller. Sow more broad beans, parsnips, carrots, peas, broccoli, lettuces, radishes, spinach, turnips, winter and Savoy cabbages and also swedes. Transplant the cauliflowers, Brussels sprouts, cabbages and broccoli that were sown in a seed bed in early spring. Harden off the tomatoes that are under glass and plant out at the end of the month. Also plant self-blanching celery. Prepare outside beds for courgettes, marrows and ridge cucumbers. Under glass, sow celery, leeks, ridge cucumbers, courgettes and marrows in pots. Early in the month, prepare ground for runner beans and put up support canes or netting. Sow runner beans towards the middle and end of the month. Earth up early potatoes.

Herbs

Harden off basil and marjoram and plant out a fortnight later.

Flower colour

Pulsatillas, star-of-Bethlehem, wallflowers, spurges, forget-me-nots, pyrethrum, sun roses, Spanish gorse, azaleas, rhododendrons, wisteria, laburnums, clematis.
