Perpetual leek: Sowing, planting and harvest calendar
How do you grow perpetual leeks?
Plant healthy small bulbs or divisions in late summer or autumn in workable, well-drained soil. Choose sun or light shade and improve poor soil with mature compost. Leave about 20–30 cm between clumps so they can spread.
Plant small bulbs with the tip upwards at the supplier’s recommended depth, and potted plants at their original growing depth. Water to aid establishment without waterlogging. Divide overcrowded clumps, preferably during summer dormancy or when growth resumes in autumn. Protect bulbs and roots, then replant healthy sections.
Prepare the bed carefully because this crop will stay in the same place for several years. Remove perennial weed roots that would be hard to extract from future clumps. When dividing, lift the rootstock gently and separate the bulbils without crushing them; discard soft or damaged parts. Mark each position with a durable label. In summer, missing leaves may reflect the plant's resting period and do not mean you should immediately dig over the bed or assume the clump has died.

Weed
Hand-weed plants growing through the clump and crowding its new shoots. Work near the surface without exposing the roots. If the space is clear, simply let the plant resume growth.
How do you harvest perpetual leeks?
Harvest mainly from autumn to spring when clumps are established and carry vigorous leaves. Plants may become dormant in summer, so do not expect continuous year-round harvests. Cut a few stems about 5 cm above soil with a clean tool, leaving the crown and some foliage for regrowth.
Avoid exhausting young plants or cutting again before they regain vigour. Clean harvested parts before cooking. Keep them in the refrigerator for a few days and use promptly; freeze prepared portions for longer storage. Save healthy small bulbs if you want to propagate the clump.
Locate the clump's base before cutting so you do not damage the bulbs that keep it perennial. Spread your picking over several shoots and retain intact sections instead of shaving the whole clump. Harvesting leaves does not require routinely lifting the rootstock. If foliage yellows and disappears in summer, mark the position so you do not dig it over by mistake. Resume small harvests when fresh shoots have become well developed again, rather than cutting the first fragile leaves immediately.
