I tried growing onion shallots in a poly tunnel for spring use. I couldn’t find any so I bought some in the supermarket. I planted on 1/10/11 but out of 15 planted only 2 have sprouted and are only 2 inches long. The rest have small roots only. Have they been treated to keep them dormant or what?
More likely it was warm weather during the autumn that kept them dormant, or at least most of them.
With some cold weather, this should right itself.
There is a danger of bolting … producing flowers … when shallots are planted so early.
