If they aren't showing signs of overwatering (yellowing leaves, etc..), my guess would be the high temps. If you can shade them through the hottest part of the day, I'd give that a shot. Or, just wait until temps cool down.

I can make some shade... I shaded my tomatoes a few months ago and that seemed to help them a little. I'll try that. Also they have taken a beating by what I *think* are leaf-cutter bees. Not looking pretty.

Here's hoping for the best. 8) Thanks!

The shades help my peppers which have continued to set fruit since I put up after the temps shot up. I put them up to stop the sun scald but the peppers are really producing fruit right now and our temps in Phoenix are the same as yours the last several weeks. I also just went to two days on the water timer.

Awesome, this gives me hope! Thanks farnell and tsheets!
