Sow indoors

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 the warmth, 15-20°C and keep moist.

Grow on

Keep seedlings in a light position, but shade from direct sunlight. When large enough to handle, transplant 5cm apart into trays of potting compost.

Harden off/plant out

Gradually accustom plants to outside conditions for 2-3 weeks before planting out when danger of frost has passed. Allow 25cm between plants.

Aftercare

Remove faded flowers during summer to prolong blooming.
