i overwintered onions on my allotment, i was wondering if i should give them a perk up by feeding them .i,m growing them under large cloches,as for the past 2 years the wind has wrecked them!!
How cold is it where you are? I would feed them when it warms up a bit.
hi 8 degees ta presnt during day droping to -1/2
Gosh, you are way north of me, I live in France and it's -5° at night and not much above freezing in the day this week! Perhaps start feeding in March, but I'm probably not the best person to advise you. Onions grow brilliantly here, I plant sets late March and they are ready to harvest in late July.
