I don't know why people say plant zucchini and other squash with large leaves in "full sun," unless they live on some chilly wasteland. Where I live full sun means a generally low humidity 90-110 F high temps and any broad leaved plant like zuccini or other squashes (or even spinach or beets or bok choi) will wilt and die in that condition no matter how much you water it. In general DO NOT plant broad leafed veggies in full sun. They are forest floor plants, they have broad big green leaves to make use of limited sun light. If you've ever toured where professional produce growers grow broad leaved veggies, they tend to have partial shade covers over their grow plots. Best place to grow Zuccini is where it gets morning sun then shade by noon.
