Onions slow to bulb

Had a call from a fellow grower last night and he's having similar problems. Now we've got past the longest day and the nights are getting longer they should start to swell but it's going to be well into August before I can harvest my biggest onions, which won't give them long enough to ripen for the first shows I feel.














My onions for the 8oz class (Vento and Tasco) should be on time however, and I think I'll be harvesting my first by the middle of July no problems.
