Mature zucchini plant suddenly died?
I had two mature, already-producing zucchini plants suddenly die over the course of 24hrs. On Sunday it rained all day and the leaves were really droopy - I assumed it was water-logged and that it'd dry back up with the hot sun the following day. Nope - both dead. Now my nearby butternut squash is starting to look the same - yellowing, droopy leaves.
Maybe squash vine borers? But I don't see the 'sawdust' - the root was all mushy :( I hope it's not too late for the butternut squash!! We live in zone a/b (Asheville).
