Things to do in your
Mapesbury garden in April:
Weed, feed and mulch borders with
general-purpose fertiliser and organic matter.
Apply general-purpose fertiliser
around shrubs prior to mulching which will help conserve moisture and deter
Deadhead Spring bulbs before they
seed and plant Summer flowering bulbs e.g. Gladiolus.
Divide herbaceous perennials and
redistribute around garden.
Put supports in place for larger
Tear off Rosa suckers, which can
weaken the plant.
Tie in climbing and rambling roses.
Feed roses in general.
Weed and feed the lawn.
Plant Evergreens, Perennials, Trees
Remove dead Hydrangea flowers and
reduce thin/old shoots on lacecaps and mopheads to lowest bud, to encourage
strong, new growth.
Prune Spring flowering shrubs that
have just flowered e.g. Forsythia stems back to stronger, younger shoots and
remove roughly a fifth of older stems at the base to stimulate new growth.
Lightly prune Lavender to just above new shoots.
Though dead wood is mostly removed
from trees and shrubs in Winter, on deciduous shrubs like Philadelphus , it
is hard to tell in Winter what is dead wood and what is not, so now the
leaves are showing is a good time to do this.
Remove around 5cm of old compost
from pot plantings and replace with new.
