Temperatures That Are Low According to the findings of the United States Department of Agriculture Research Service, tomato plants can withstand temperatures as low as 33 degrees Fahrenheit, but they begin to experience issues when the temperature drops below 50 degrees F.
How cold can tomato plants survive?
Even while tomato plants can withstand temperatures higher than freezing, they will still suffer damage if they are subjected to temperatures lower than 55 degrees Fahrenheit for an extended period of time (13 degrees Celsius). How tomatoes are impacted by cold depends on both the temperature at which the cold is experienced and the length of time it is experienced.
What is the best temperature to grow tomatoes?
Temperature and the Growth of Tomato Plants In the summer, when temperatures climb beyond 90 degrees Fahrenheit (32 degrees Celsius) and nights remain above 76 degrees Fahrenheit (24 degrees Celsius), the tomato plant may, once again, experience damage to immature fruit or loss of blossoms.
Will 40 degrees kill tomato plants?
What is the lowest temperature tomato plants can tolerate?
Your tomato plants will suffer harm if they are exposed to temperatures that are higher than 40 degrees Fahrenheit (4.4 degrees Celsius). However, it will not kill them in a straightforward manner. Instead, chilling harm will be caused by extended exposure to this temperature, which will result in a reduction in the vigor of the plant.
What happens to tomato plants when it freezes?
There is little question that this will also have an effect on the yield. If the temperature drops below 32 degrees Fahrenheit, this is termed a freeze or frost and will almost certainly destroy tomato plants if they are not protected from it. On the other hand, if the temperature drops below 40 degrees Fahrenheit, it is possible that the plants will live, but they will exhibit a great deal of growth difficulty.
