Start sowing courgettes
COURGETTES TEND to germinate pleasingly quickly and are sown 2 cm deep, individually, into 9cm pots. After watering, it’s into the propagator at 18-20°C until the seed leaves appear, when the plants are moved to develop in the more open environment of the heated greenhouse. Courgettes resent root disturbance, so use pots rather than cell trays to avoid transplant shock when planting out in June. Courgette seeds are often sown edge side down to assist germination and avoid decay. On the programme this month, Jim will be sowing larger seeds to see if orientation and position makes a difference to their germination.
