Hi there Im a development Horticulturalist with Fairfield city council, I just wanted to find out what types of onion are transplanted from seedling. The reson i ask is i have only ever heard of direct sowing of onion seed and transplanting is very unsucessfull (especially in your common spanish, white and brown varieties).

Onions can be raised in seed trays or punnets and transplanted when about 10-15cm tall. They should be planted with just the roots covered. If sown direct, the emerging plants may need thinning. I have been successful with both methods for brown and red onions and with spring onions from seedlings.

Onions can be successfully planted as seedlings.Grow in trays transplant at about 15cm.Before transplanting trim tops and roots by about one third, dig shallow depression, lay plants with roots only in depression and cover roots with soil. Important to select correct onions for time of year(see packet)
