Curly endive: Sowing, planting and harvest calendar
How do you sow curly endive outdoors?
Sow curly endive outdoors once the soil has warmed sufficiently, usually from late spring through summer depending on climate and variety. Follow the seed packet dates: an early sowing exposed to cold can encourage bolting. Choose fertile, well-drained soil in sun or light summer shade.
Sow in drills about 1 cm deep, with about 30 cm between rows. Cover and water gently to keep the soil moist without waterlogging. Thin gradually to about 25–35 cm between plants for whole heads; baby-leaf crops can be grown more closely.
Sow small batches at intervals to spread harvests. Watch for slugs, snails and damage to seedlings. Identify the problem before taking action, rather than relying on eggshells or mulch to prevent every attack.
Check the seed packet carefully: curly endive is grown for its garden leaves, unlike Belgian endive produced by forcing a root. After thinning, check that the remaining seedlings stand upright and are well anchored. Water the soil gently to restore contact around their roots. A clearly marked row makes later weeding easier without damaging the small rosettes.
How do you harvest curly endive?
Harvest according to plant development, variety and sowing date. Curly endive can be picked as baby leaves or whole heads, rather than only in autumn and spring. For repeated pickings, cut a few leaves while protecting the growing centre and allow the plant to regrow.
For a whole head, cut the stem at the base with a clean knife and remove damaged outer leaves. Garden blanching is optional: it means excluding light from the centre to make it more tender, rather than dipping leaves in boiling water. If you blanch a head, start with dry leaves and harvest promptly once it is ready.
Eat curly endive promptly or keep it briefly in the fridge. Discard spoiled leaves. Freezing changes the texture: use frozen leaves in cooked dishes rather than a crunchy salad.
Choose ready plants individually rather than cutting the whole row. If you cover a head to blanch it, inspect it regularly: trapped moisture encourages leaf deterioration. Stop if you notice rot and discard affected parts. A head harvested green is still usable; blanching should not become a compulsory step before every picking. Match the amount you cut to what you will use promptly.
