Leeks in Barnhill

Dig the bed well and work in compost before planting time. Leeks do best in moisture-retentive but free-draining soil, and a loose, stone-free tilth helps the stems grow straight around 27th February - 14th March.

Sow seeds thinly in modules or a seed tray around 13th January - 14th March, about 1 cm deep. Keep them at 15–18 °C and water gently so the compost stays moist but not sodden.

Move seedlings on when they are large enough to handle, from 5th March. Pot them into small modules or deeper trays so the roots can develop without crowding.

Set plants outside for a few hours a day before planting out. Do this over 30th March - 13th April so they adjust to wind, sun and cooler nights without checking growth.

Plant sturdy seedlings into deep dibbed holes around 30th March - 13th May, leaving just the base of the leaves at soil level. Water in thoroughly at once, then let the soil settle naturally around the roots rather than firming hard.

Keep the rows weed-free and draw soil up around the stems as they thicken. Start from 21st April and repeat as the plants grow, keeping moisture steady in dry spells so the stems stay tender and pale.

Lift leeks from 18th September once the stems are a usable size, then keep picking through 18th February. Use a fork to loosen the soil before pulling, and take what you need rather than clearing the bed at once.
