Q.Triple digit temps and growing tomatoes outside

Zone Mesa, Arizona 85203 | Anonymous added on August 26, 2020 | Answered

I’ve tried unsuccessfully to grow starter tomatoes in the direct sun, in 100° plus days. Only to have them die. I water daily, in the cooler mornings. What am I doing wrong?

They should also be mulched around the base.

Here are two articles that you should read about dealing with that kind of heat:
