- Best sown in autumn direct to seed beds or in trays 1/2″deep for transplanting prior to winter.
- Not suitable for spring sowings / with exception of late winter Jan / Feb under-cover as a secondary option..
- If transplanting bare root seedlings from drills in drier weather, plants can be clipped to three inches to reduce stress whilst they establish.
- If grown in plugs transplant to final growing position by early Oct.
- Thin to 5 inches apart when plants are 6 inches tall.
- Harvest by pulling bulbs when tops are brown and dry. Can be harvested early whilst green as these do not store well into winter.
- Fertile, moist soil enriched with compost is best for onion production.
- Onions are claimed to ward off many insect pests around lettuce, cabbage and carrots.
