Can tomatoes survive frost damage?
In tomato, freezing causes a darkening of the leaf or stem tissues. Damaged areas later wilt and turn brown. Peppers are more sensitive than tomatoes to freezing temperatures and may be injured or killed by a light frost. Tomato plants are also susceptible to chilling injury at temperatures between 0 and 5° C.
At what temperature will tomatoes die?
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.
Will a light frost kill tomato plants?
