When do you harvest your bulb onions ? Has anyone ever been able to get the tops to dry down in short seasons ? Here at 4000' in Montana, it doesn't seem possible. The water has been off the patch for 2 weeks now and no drying of the tops.
I am also curious about frost tolerance of mature onions. We have always pulled ours, when the tops are green before any heavy frosts. This year with hoping the tops will dry some, I've been covering them with row cover on the few 30 degree mornings.
