Sow into trays of Yates Seed Raising Mix. Firm down, water gently and keep moist through germination period. Transplant when large enough to handle.
Choose a well drained position in full sun. Add Yates Blood & Bone and Yates Garden Lime before planting, and fertilise regularly with Yates Thrive Soluble Plant Food. Protect from snails and slugs with Yates Blitzem.
Trim lightly after each flush of flowers to encourage new growth. Grow as an annual.
