Sowing & growing

Sow under glass Mar-May in trays of moist seed compost. Cover with a very light layer of vermiculite or seed compost. Germination best at about 21°C. Transplant seedlings into individual pots when large enough to handle & keep protected from frosts. Acclimatise before planting out May-Jun. Can be sown in situ May-Jun in fine, moist soil.

Aftercare

Keep soil moist until plants are established. Pinch out the growing tips of young plants for bushier growth. Deadhead regularly to keep plants blooming until first frosts.
