Triple digit temps and growing tomatoes outside

Question

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?

Answer 1

Most plants and fruits cannot tolerate triple digit heat for long. Plus, tomatoes can't set fruit much past 90 degrees F. You can train tomatoes to climb a wire surround or basket so that they can provide their own shade, or use shade cloth to protect them from the searing heat. They should also be mulched around the base.

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