White cabbage: Sowing, planting and harvest calendar
How do you sow white cabbage under cover?
Before sowing white cabbage under cover, check the season on the seed packet. Summer varieties can be started in late winter, while autumn and winter varieties often have a later timetable. Sow small batches to spread future harvests rather than raising a large number of plants of the same age.
Use a clean module tray or small pots with drainage holes, filled with fine, free-draining seed compost, preferably peat-free. Moisten the compost before sowing. Put one or two seeds in each module about 1 cm deep, cover them and water gently. Label each variety with its sowing date.
Place the containers in a greenhouse or beside a very bright window. Follow the temperature recommended for your variety and avoid an overheated growing space. Keep the compost moist without standing water and provide ventilation. After germination, retain the stronger seedling in each cell, cutting off the other to protect the remaining roots.
A height of around 10–15 cm, five or six true leaves and a well-rooted plug are useful signs for preparing to plant out. Gradually harden the plants off to outdoor conditions; the final move also depends on the weather. Not needing extra feed during sowing does not mean that poor soil will support the entire crop later.
