Can tomato plants tolerate 40 degrees?

Tomatoes' Temperature Range

Although mature plants might survive light frosts, temperatures below 40 F damage flower and fruit production, making tomatoes perennial only in U.S. Department of Agriculture zones 12 and up. ... Tomatoes flower and set fruit best when the air and soil temperatures range between 60 and 70 F.

Is 5 degrees too cold for tomatoes?

Tomato plants are also susceptible to chilling injury at temperatures between 0 and 5° C. Chilling can cause stunted growth, wilting, surface pitting or necrosis of foliage, and increased susceptibility to disease. Low soil temperatures also stunt plant growth and prevent root development.

Is 35 degrees too cold for tomato plants?

Tomato plants will survive temperatures down to freezing, so a low temperature of 35 degrees will not kill them. Insulate the plant with sheets or cloches if frost threatens. To ensure plant safety, protect tomato plants any time a temperature of 35 degrees or below is expected.

What low temperature can tomatoes tolerate?

Temperatures below 50º F can destroy some ripening enzymes, and when the thermometer dips below 40º F, the chill can actually cause the tomatoes to decay more quickly in storage.

What temp is too low for tomatoes?

Low Temperatures

Temperatures below 55 degrees Fahrenheit are too low to grow a healthy tomato plant, says The University of Arizona Cooperative Extension. The low temperatures interfere with normal pollination of the blossoms, which drop off the plants. Fruit fails to set, so no tomatoes are produced.

Can tomatoes tolerate 45 degrees?

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 garden plants?

Hardy vegetables tolerate cold temperatures the best—their seeds will germinate in cool soil, and seedlings can typically survive heavy frost. Plant these seeds or transplants two to three weeks before the date of the average last spring frost; they will grow in daytime temperatures as low as 40 degrees Fahrenheit.

Is 40 degrees too cold for plants?

Times for planting might include late winter or early spring, when temperatures fall below 40 degrees at night in most parts of the country. ... After hardening off the annual seedlings, you can plant hardy annuals if the temperature stays at 40 degrees or above.

Should I bring my tomato plants inside at night?

What temp is too cold for plants?

The general rule of thumb is that most plants freeze when temperatures remain at 28°F for five hours. Of course, there are exceptions to this rule. Seedlings, with their tender new leaves, often give up the ghost when temperatures dip to 32-33°F. Tropical plants have differing low-temperature thresholds.
