My whole garden got some hail damage about two weeks ago, and I have been assuming that was the reason one of my cuke plants had suffered split and cracked stems. It seems to be doing fine and has sort of fallen over and started to put down roots further up its stem, so I wasn't worried. Then today, I noticed a weird blistering on the nearby okra plants. About an inch above the soil and below the leaves, the skin of the okra stem is all bubbled up. I see no eveidence of insects but don't want to unneccessarily slice open the stems to investigate. Everything is fairly young. The cukes are having their first bloom, and the okra is only about 6 inches high and just starting to get its true leaves. Any ideas?
