Courgettes and squashes - Cucurbita spp.
Varieties
Fl hybrid courgette varieties usually begin cropping earlier and produce more fruit. Look out for varieties resistant to cucumber mosaic virus. Other summer squashes could also be grown, but look out for bush varieties — many other varieties will be too rampant.
Sowing
Sow in individual 8-9cm pots at a temperature of 18-21°C, approximately five weeks before planting out.
Planting
Plant in the greenhouse border as soon as conditions are frost-free — usually in lath spring The border should be well manured or composted. Allow 1sq m per plant. Keep with cucumbers in the crop rotation.
Harvesting
Harvest from early summer to mid-autumn, or until cleared to make way for autumn crops. Harvest regularly, or you will quickly end up with marrows!
Pests, diseases, and disorders
The plants are generally vigorous enough to overcome most problems, although cucumber mosaic virus can ruin the crop. Powdery mildew may affect established plants in hot weather.
