Courgette plants are one of the last crops to be sown under cover – in a greenhouse or on a sunny windowsill. They take a week to germinate and the young seedlings soon develop their true leaves. Plant them out in the garden when after all risk of frost has passed, hardening them off first – they will grow very quickly.
More on growing courgettes:
You Will Need
- Courgette seeds
- Small pots
- Multi-purpose, peat-free compost
- Seed trays or pots
- Vermiculite, Optional
- Watering can
Step 1
Fill a pot with multipurpose compost that has been kept in the greenhouse, so that it is already warm. Firm well and press a couple of seeds, on their sides, into the compost.

Step 2
Cover the seeds with compost or vermiculite, which is warm and free-draining and helps stop young seedlings from rotting during cool night temperatures.

Step 3
Soak with tepid water and place in a propagator or a tray covered with a clear lid, at a temperature of 20°C.

Be sure to protect your young plants from slugs when they’re first planted outside – otherwise they may be devoured very quickly.Protect young plants from slugs
