Sowing & growing

Start early inside March-April. Sow in pots of seed compost 12mm deep, and keep moist. Place in cold frame or greenhouse, and acclimatise before planting outdoors, when risk of frost has passed. Alternatively, sow directly April-May in a well-prepared seedbed, raked to a fine tilth. Keep moist until established.

Aftercare

Prefers to grow in well-drained soil exposed to full sun. Stems may need staking if growing in an exposed site.
