powdery mildew and fruit on vine
The powdery mildew didn't hit until late August this year, but when it did, it spread extremely fast. Since so many of my squashes had just barely survived vine borers, and it was almost September, I decided to not fight the PM and to let the vines die off. Will this hurt the winter squash fruits that are still on the vines but not yet fully mature? If I leave them on until the vine is brown from the PM, will the fruits rot? The two plants that have a lot of fruit are the birdhouse gourd and the delicata. Some of the delicata are starting to turn spotty orange, so I picked them to cure. But the birdhouse gourds are still pretty green and soft.
