Most plant cells are killed at temperatures from 122☏ to 140☏.Īdequate water and shade can help reduce blossom drop and cell damage when temperatures are very warm or hot.

Anything over 85F (29C) is too hot for carrots. When temperatures rise above a plant’s temperature range the plant will go dormant–that is quit growing (the same is true when temperatures fall below the range). Tomato flowers may drop if the temperature rises above 90☏ during the day or 75☏ at night. The optimal temperature range for peppers and eggplants, for example, is 70° to 85☏ pollination will not occur if the night temperature falls below 55☏, and blossoms may fall if the temperature rises above 85☏.īean blossoms may drop off if temperatures remain warmer than 85☏ for more than a day or two. ![]() Vegetables are sensitive to hot temperatures–just as they are sensitive to cold temperatures.Įach vegetable crop grows best in its own range of temperatures.
