Plant Propagation

Seed - sow spring in an outdoor seedbed. Germination usually takes place within 3 weeks. Plant the seedlings into their permanent positions when they are large enough to handle. If seed is in short supply, it can be sown in spring in pots in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in early summer.
