In early spring, sow seeds shallowly in trays and keep under glass, transplanting them into individual pots when they're large enough to handle. Harden off before planting outside after the risk of frost has passed. Alternatively, sow in-situ in mid to late Spring, in a well-prepared bed. Thin the seedlings out as they grow to allow approximately 30cm between each plant. As the seedlings grow, pinch out the tips to encourage bushier plants.
