I'm only growing Tomatoes and Okra right now, so I'm not much help. But I heard the Okra loves sun, so they are getting the full brunt of the sun...my tomatoes have been under shade cloth(actually I'm using burlap), I had the thin frost cloth, but has since ripped apart from extreme UV rays?I've had them under them for at least 5 weeks or so. It is doing so much better since, they are not wilting as much and are ripening now. I would think they would all benefit from some shade during the hottest afternoon sun? Good luck!
