Courgette plants are one of the last crops to be sown under cover - in a greenhouse or on a sunny windowsill. They only take about a week to germinate and the young seedlings soon developing their true leaves.
Keeping the compost in the greenhouse or undercover will ensure it is already warm before starting seed sowing. Fill a pot with multipurpose compost, firm it well then press a couple of seeds on edge into each pot.
Cover the seeds with more compost or use vermiculite, which is warm and free-draining and helps stop young seedlings from rotting during cool night temperatures.
Soak with tepid water and place in a propagator or a tray covered with a clear lid, and keep at a temperature of 20Â°C.Â
Only plant them out when all risk of frost has passed, ensuring they are hardened off first â€“ you will find they will grow very quickly.
