Temperature Range to Grow Tomatoes

By Amy Deemer ; Updated September 21, 2017
Tomatoes are a warm weather crop.

Tomato plants tolerate temperatures that are less than 55 degrees and over 100 degrees Fahrenheit, but after a few days of extreme to low or high temperatures, the plant will experience blossom drop. Tomatoes thrive when grown in temperatures that range between 70 to 90 degrees Fahrenheit.
