Prick out and pot up young seedlings and cuttings
before they become overcrowded. |
|
Start hardening off bedding plants but put plants under cover
if frost threatens. |
|
Control pests and diseases especially slugs and snails. Ventilate
cold frames and greenhouses whenever possible. This encourages sturdy plat
growth. Remove winter insulation from greenhouse and put on shading. |
|
Place supports in position around perennials that require
staking. If the supports are put in position early, the plants will grow through
them and hide them. |
|
Stop chrysanthemums as close as possible to the ideal date
for the type you are growing. |
|
Plant hanging baskets and keep them in a greenhouse or frost-free
conservatory or porch. |
|
Apply a general slow-release fertiliser to containers; applied
as a surface dressing in spring it should last plants in containers the whole
growing season. |
|
Start removing sideshoots and pinching out tendrils if growing
sweet peas on the cordon system. |
|
Feed shrubs, trees, new hedges and fruit bushes as necessary. |
|
Hard prune shrubs, such as buddleja, that produce their best
show on vigorous new wood. Prune spring-flowering shrubs that are over three
years old once they have finished flowering. |
|
Protect brassicas, such as cabbages and cauliflowers, with
brassica collars against cabbage root fly, and erect plastic screens in the
vegetable garden to deter carrot fly. |
|
Earth up early potatoes to protect them from light and frost. |
|
Begin mowing the lawn regularly. Frequent mowing encourages
dense growth. |
|
Feed fish when they become active again after the winter. |
