Possibly the early start on the growing season, but I suspect the seedlings were stressed due to the heat and dry conditions at least here in northeast PA, but as I said I've never seen it happen. yeah Ranger carrots used to drive me nuts too, if I planted a large patch hoping for a good canning season, they would be terrrible, and if I just planted a small patch they would be perfect, go figgure, I gave up on em years ago.............steg
