Tips & Advice:

Sowing Indoors

Almost fill a seed tray with moist seed compost. Sow seeds 5mm deep and lightly cover with a little more compost. Place in the warmth, 15-20°C and keep moist.

Growing On

Keep seedlings in a light position but shade from direct sunlight. When large enough to handle, transplant into trays of potting compost.

Hardening Off/Planting Out

Gradually accustom plants to outside conditions for 2-3 weeks before planting out from April onwards. Allow 20cm between plants.

Aftercare

Outdoor sown seedlings can be thinned and thinnings replanted in other areas of the garden.
