Then, what is the lowest temperature tomatoes can tolerate?
Although tomato plants can survive temperatures down to 33 degrees Fahrenheit, they show problems when temperatures drop below 50 degrees F, according to the U.S. Department of Agriculture Research Service.
One may also ask, what temperature can seedlings handle? Keep an eye on the nighttime temperatures in your area as you transplant seedlings outdoors. Some plants, such as onions, can handle freezing temperatures after you harden off seedlings. Other plants, such as tomatoes, will suffer if the temperature goes below 65 degrees Fahrenheit (18.33 degrees Celsius).
Considering this, how cold is too cold for tomato seedlings?
Tomato plants at any age or stage do not tolerate frost. You can generally move young seedlings outdoors when the temperature rises about 45 degrees Fahrenheit. A temperature of 46 F would be warm enough for tomato seedlings.
Is 40 degrees too cold for tomatoes?
Although mature plants might survive light frosts, temperatures below 40 degrees Fahrenheit damage flower and fruit production, making tomatoes perennial only in U.S. Department of Agriculture zones 12 and up. They flower and set fruit best when the air and soil temperatures range between 60 and 70 degrees.
