This is not sun scald, or some strange fungal thing. This is frost damage, here on a winter squash. In the middle of July. The plant will survive, but excuse me? Are we entering a mini Ice Age here? Can I not expect to grow frost sensitive vegetables and not have to worry about covering them up every night in the summer?
On the other hand, the sugar snap peas, which I planted pretty late, are thriving. As are the kale and Swiss chard. The tomatoes and other frost wimpy plants survived too.
