I guess I should have been more specific. The "row cover" I was referring to is like cloth, not plastic. It's white and permeable, not clear. They use it around here even in July because it provides shade, lets moisture and gasses through ie it breathes. It protects against both frost and overheating. It is probably the best way to grow zucchini squash in OK, because of the severe squash bug problem we have. I have managed to get a crop of squash without it, but very hit or miss. So next year I am going with it instead of plastic like I have in the past.

The strategy is to plant in late june/early july and keep the squash covered until the plants are mature then remove the cover of a "section" every week or two. This supplies a steady supply of squash all season for market. As the old becomes infested, remove them and plant a fall crop of something like broccoli or cabbage.
