  1. Some of those I know of do NOT like the full blast of afternoon sun in the heat of summer (95f+) Tomatoes and bell peppers will get hot spots on them. So, they need to be provided some shade during the hottest time of day.

    • I second this! I live where it it very hot/dry in midsummer, and our tomatoes simply stop producing fruit when it gets into the upper 90’s, then start producing when the blistering August heat gives way to September. I’ve read that they won’t set fruit above 85 degrees, so a simple shade might help.
