In warm weather, sow vegetables and hardy annual flowers in drills sprinkled with GroChar.
Move young plants out of the greenhouse and into coldframes towards the end of the month.
Plant out new plants in the border with GroChar concentrate in the planting hole, or in containers of all-purpose GroChar compost.
Divide overmature plants and replant in the border with GroChar concentrate in the planting hole.
Give roses final prune and top-dress with garden compost and GroChar to improve the soil.
Clear ground round fruit trees and top-dress with compost and GroChar.
This is the peak time for getting seeds sown – vegetables, salads, herbs and half-hardy annuals can all be sown in GroChar seed compost this month. Use of a heated propagator will speed germination.
Prick out and pot on seedlings as soon as they are large enough to handle into GroChar potting compost. This will ensure that they keep growing strongly until they are ready to be put in their final planting positions.
Pot up dahlia tubers and stand them in a frost-free place to start back into growth.
