Sow: April in seed trays. Prick out into individual pots. Plant out in June. Seedlings are prone to 'damping off' (a fungal infection).
Care: Pinch off flowers as they appear as they coarsen the leaves.
Water: needs plenty of water as it grows.
Harvesting: Pick leaves from the stem tips, not the sides, to keep the plant bushy. And remove any flowers to prolong its life.
