Q.spaghetti squash leaves suddenly wilted
Yesterday vines were fine but this afternoon leaves are starting to wilt and lay over – main flowers are starting to droop over. In other plants I would suspect a water issue but other vegetables are doing fine and we haven’t been particularly dry.
There are a couple of possibilities. One is borers https://www.gardeningknowhow.com/edible/vegetables/squash/squash-pests-identifying-and-preventing-squash-vine-borer.htm
the other is bacterial squash wilt, though it's typically found early in the season: https://www.gardeningknowhow.com/edible/vegetables/squash/signs-and-treatments-of-squash-wilt.htm
