How to Guide
Almost fill a seed tray with moist seed compost. Sow seeds thinly over the surface and lightly cover them with a little more compost. Place in warmth at 15-25C (60-75F) and keep moist.
Potting on/Thining Out
Keep seedlings in a light position, but shade from bright sun. When large enough to handle transplant individually to 8cm / 3in pots of potting compost.
Hardening Off/Planting Out
Gradually accustom plants to outside conditions for 2-3 weeks before planting out when danger of frost has passed.
