The firm heads remain in good condition for a long time, producing plenty of side shoots once the central head is cut. Can be planted in succession for an ongoing harvest from later summer to autumn.

When to sow - April to May
Plant out - May to July
Where to sow - Sowings can be made in trays or modules under glass at 13°C. Later sowings can be made into a seed bed in shallow drills 2cm (3/4") deep in short rows.
What to do next -As soon as glasshouse seedlings show their first pair of leaves, prick off into trays 5cm (2") apart or thin modules to one seedling per cell. Gradually harden off before planting out, spacing plants 45cm (18") apart, then once plants are 15cm (6") tall, they can be lifted and transplanted to their final planting positions spaced the same as detailed above.
Harvest - July to September
Handy Tip - Keep plants well watered during very dry weather especially as heads start to form.
