Harden off summer bedding
plants and plant out. Check the weather forecast
regularly and be prepared to provide temporary
protection, with newspapers or horticultural fleece,
if frost is forecast. |
|
Thin out hardy annual, vegetable
and other seedlings sown outdoors. |
|
Maintain a programme of weeding
and checking for pests and diseases. |
|
Water and feed plants as necessary.
Pay particular attention to seedlings, plants in
containers and newly planted trees and shrubs. |
|
Take basal cuttings of border plants,
such as lupins and delphinium, before they develop
hollow or pithy stems, at which point it is too
late for successful cuttings. |
|
Stake and support chrysanthemums
except compact varieties and dwarf bedding. Stop
incurved and large exhibition chrysanthemums this
month. |
|
Prune spring-flowering clematis
after flowering. |
|
Finish planting of permanent containers
so plants have the summer to establish themselves. |
|
Pinch out the growing tips of bush
fuschias while the plants are still small, and
check all types of tender greenhouse cucumbers
and tomatoes. Remove male flowers from cucumbers. |
|
Prune winter-flowering heathers.
Any not pruned by the end of May should be left
until next year. |
|
Plant onion sets as soon as possible. |
|
Earth up early and maincrop potatoes;
protect foliage if frost is forecast. |
|
Cut lawns with naturalised bulbs
growing in them. Keep mower blades high. |
