The Ornamental Garden in April
A busy month in prospect providing the weather is such, that it allows you the gardener, to do much more outdoors.
Again it must be said: Only carry out the following tasks if condititions are favourable.
Week 14 - 2nd Apr. to 8th Apr.
Layer Calluna / Heathers.
Week 15 - 9th Apr. to 15th Apr.
Remove winter protection from Ferns if conditions allow.
Plant out Dierama if not done previously.
Cut out damaged Dierama leaves and flower stems if required.
Prepare bed for Gladioli.
Week 16 - 16th Apr. to 22nd Apr.
Sow Alyssum seed insitu if soil conditions allow.
Cut back any frost damaged Choisya shoots.
Stop (remove tip) established Dianthus chinensis.
Top dress containerised roses.
Similarly,top dress flower beds with a General fertiliser in readiness for planting out.
Commence feeding Wisteria.
Week 17 - 23rd Apr. to 29th Apr.
Once the flowers on Spring bulbs have faded,deadhead them to prevent them wasting energy producing seeds.
Do not remove the foliage at this stage!
After deadheading, sprinkle a granular fertiliser around the clumps or drench with a liquid fertiliser to give them a boost.
Mulch Phlox paniculata.
