From mid-April - Sow, sow, sow

Dig In and gently push each seed into a small pot of multipurpose compost so it stands vertically. Water, allow to drain, then place indoors on a warm windowsill.

Late May to June - Grow, grow, grow

After about four weeks you'll be ready to plant out. Don't do this until all threat of frost has gone! First harden them off by standing them outside in a sheltered spot during the day and bringing them in at night for at least a week.

Plant each young plant into:

  • - a football-sized hole filled with a mix of soil and well-rotted manure or compost. Position each plant one metre away from its nearest neighbour
  • - a growing bag from your local garden centre
  • - a patio pot that is at least 30cm wide filled with multipurpose compost.

Choose a sunny spot. Courgettes are thirsty veg, especially when in flower and the veg are starting to swell. Give them a good soaking once a week in dry spells. If growing in pots or bags you'll need to water more often.

July to September - Grub's up

To keep plants productive you need to harvest courgettes at least once a week at the height of the season. Once they're around 10cm, use a sharp knife to cut the veg from the plant. Courgettes are best eaten fresh or can be stored for a few days in the fridge.
