Growing courgettes from seed
Sowing and planting
For early crops, sow courgette seeds indoors in mid-spring. Sow seeds in pots or module trays using moist multi-purpose compost. For later crops, sow seeds outside in late spring.
When seedlings appear, move stronger ones to larger pots. Throw away weaker seedlings. Grow on indoors until ready to plant outside in late spring, after the last frost. Space plants 90cm apart, then mulch the surrounding soil generously to hold in moisture.
If you don't have the time or space to sow seeds indoors, then you can buy ready-grown, vigorous plants from most garden centres in late spring.
Tending the crop
Plenty of moisture is the key to success. A constantly just-moist soil is essential if plants are to crop to their full potential. So water regularly and apply a thick layer of mulch to hold water in the soil.
In dry conditions, most varieties produce mainly non-fruiting male flowers. To encourage female flowers, which are the ones that produce fruit, water generously and regularly. Apply tomato fertiliser once a fortnight to promote growth and flowering.
