I seem to be having the same issues~!! I have been watering with Molasses so would this not serve as Corn Syrup would? Also this seemed to happen after 4 days of straight rain. One other thing I have thought about. I drove long wooden stakes down beside each plant so I can cover them from frost since I need to get them through to the end of October. Do you think I hurt the root systems on my plants??? I have 4 of them that are doing this same thing. The others seem fine. I posted photo's in a Thread I made called "This Happened over night" Could it be the stakes that did it to the roots? Too much rain??? I have been using fertilizer 10-52-10 plus the molasses. I am worried this is internal and if it is what comes next???? Is it the rain???? I have my plants in my garden and that has black plastic all around it. I can not remove it...too expensive. Should I prune it??? I need answers too....Please advise. Thanks. Oh I live in Maine.
