A couple of the stalks in the middle of the rows are wilting. What could cause this? frances 1 Answers 0 Vote Up Vote Down Gerry Daly Staff answered 6 years ago This could be blackleg disease which causes the lower stems to rot on an occasional plant. Remove and destroy the affected plants. It is likely to affect just a few plants. Do not save your own seed potatoes for next year.
