Sowing Months Flowering Months Harvest Months
  • Sow seed, 1cm (1/2in) deep in trays or 7.5cm (3in) pots of freedraining compost.
  • Place in a propagator or seal containers inside a polythene bag and keep at 20-25°C (68-77F) until after germination which takes 7-10 days. Do not exclude daylight as this helps germination.
  • Gradually acclimatise to outdoor conditions for 10-15 days before planting out after all risk of frost, 60cm (24in) apart.
  • Water regularly and feed with fertiliser every 2 weeks once fruits start to develop.
  • Pick courgettes regularly to ensure continuous crops.
  • Can also be sown direct outdoors once the soil has warmed. Sow 2 seeds every 60cm (24in) and thin out to the best seedling.
