This had had the white spots on it I posted about earlier, which turned out to be powdery mildew. So, I removed the affected leaves so it wouldn't spread, but it seems to have "fallen over" -- perhaps I took the leaves too close to the stem, removing the supporting "leaf stem"?
Any ideas what to do at this point? It has a nice squash that's pretty much ready (protected under the plastic container in the first picture), and three or four others.
One smaller one was found chewed, so now that the woodchuck's gone there's still something getting in. Electric fence going up soon.
