How do you sow your Jaune Gros du Poitou leeks under cover?
Sow ‘Gros du Poitou’ under bright cover in late winter or spring, adjusting timing to your climate and seed packet. Use free-draining seed compost in pots or a tray. Sow thinly about 1–1.5 cm deep and water gently.
Keep the growing medium slightly moist without standing water and ventilate the shelter. Give seedlings enough light to prevent legginess. Harden them off before transplanting outdoors once sturdy enough, ideally approaching pencil thickness. Height alone is not enough to decide when to transplant.
