Will stand over winter to use in spring. Particularly suited to harsher climes.
Outdoors: sow thinly, March-September, where they are to crop, 1.5cm (½”) deep, directly into finely-prepared, well-dug, fertile soil, which has already been watered. Allow 15cm (6″) between rows. Seedlings usually appear in 14-21 days. No thinning is required, but keep well watered in dry spells. Regular sowings, made every two to three weeks, will ensure a continuous supply through the summer. Harvest: March-October. August to September sowings will be ready the following spring.
Spring onions are ideal for growing in containers or pots of compost, on a patio or balcony where space is limited.
