WHAT TO DO IN APRIL
■ Sow marrows and courgettes in large cell trays or small pots to produce plants ready for planting out in May.
■ Coriander, dill, chervil and parsley can be started off undercover in small plug trays in gentle heat
■ Only sow cucumber seeds if you can maintain a temperature of 18-20C (65-68F) day and night to germinate the seeds. If not, wait until May.
