How do you sow Sweet William under cover?

Sow in trays or small pots under bright, ventilated cover in free-draining seed compost. For biennial growing, sow in late spring or summer; early sowing for flowers that year depends on the variety.

Sow thinly and cover lightly as directed on the packet. Keep compost moist without soaking it; temperature and emergence time vary. Transplant when seedlings have a few true leaves and are easy to handle.

Harden plants off gradually before planting outside. Space about 20–30cm apart according to variety. A deep container or stake is not always needed.
