Description

Courgette 'Supersonic' F1 is an early-fruiting yellow summer squash with a bushy, open habit that makes harvesting simple. Plants reliably produce two fruits per node, giving a steady supply of smooth, slightly tapered squash. The firm flesh has a nuttier flavour than courgette and holds well in cooking. Pick at 12-15 cm (5-6in) for best results. A productive and easy-to-grow choice for gardens and allotments. Ultimate height: 60cm (24in). Ultimate spread: 1m (3.2ft).

Companion planting: Try growing courgettes with Calendula to attract pollinating insects which will in turn pollinate your courgette flowers.

1 Packet (6 Seeds) (KJ1790)

Sowing
Indoors, sow seed at a depth of 2cm (¾") in 7.5cm (3") pots of free-draining, seed sowing compost. Place in a propagator or seal container inside a plastic bag at a temperature of 20-25C (68-77F) until germination which takes 7-14 days. Do not exclude light, as this helps germination. Once germinated, grow courgettes on in cooler conditions until all risk of frost has passed and courgette plants are large enough to be transplanted. Gradually acclimatise them to outdoor conditions over 7 - 10 days before planting courgettes outdoors in rich fertile, well drained soil in full sun at a distance of 90cm (36") apart.
More Info

Water courgettes regularly - do not allow the soil to dry out as this will impair their development. Hoe between plants regularly to prevent weeds from establishing. Courgettes appreciate an application of a high potash fertiliser every two weeks during the growing season. Hand pollinating courgettes is not usually required when they are grown outdoors. However, for indoor cultivation the female flowers can be fertilised by pressing a male flower against them. Begin harvesting courgettes from midsummer onwards when they are 10cm (4") long. Regular harvesting will encourage more courgettes to be produced.
