Keep seedlings in a light position but shade from direct sunlight. When large enough to handle, transplant into trays of potting compost.
Plant out
Gradually accustom plants to outside conditions for 2-3 weeks before planting out from April onwards. Allow 30cm (12in) between plants.
Sow outdoors
Seed can be sown outdoors when soil is warm. Sow thinly and lightly cover with a little soil. Keep soil moist until seedlings emerge. Thin to 20cm (8in) apart and transfer thinnings to other parts of your garden.
