Can tomatoes survive 40 degree weather?

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. Accordingly, they are grown as tender annuals throughout the United States.

How do you keep tomato plants warm at night?

An alternate method of protecting shrub-size tomato plants is to use cone-shaped plastic sheets with connected tubes to form a round wall around the plants. Once the built-in tubes are filled with water, thermal radiation becomes trapped in the water, keeping the plants warm at night.
