mine r fine 😉 first time ive tried ‘home growing’ this year so cant answer your question…sorry.. strawberrys coming on a treat too..ive planted alot of herbs too this year….growing rapidly…im chuffed….

Grow them next to celery and us the celery as a splint

Lay the bulbs, complete with foliage, in a warm, dry place for a couple of weeks to dry out. If onions develop thick necks use these straight away as they don’t store well and are prone to neck rot.
Make sure the foliage is completely dry before storing the crop in a dark, cool, dry place, either by hanging in nets or plaits, or packing carefully in layers in boxes. Storage life depends on the cultivar but is usually 3-6 months.
