The Q&A Archives: setting fruit on tomatoes

Question: My nights sometimes reach lows of the mid to low 50 degree temperature. Will my tomato plants set fruit?

Answer: Most tomato plants will set fruits in temperatures of 50-90 degrees. Any colder or warmer and the pollen is sometimes rendered sterile. There's not much you can do to change things in your garden except cover the soil with black plastic or set water filled milk gallon jugs in the garden (which will absorb heat during the day and radiate heat at night).

Best wishes with your tomatoes!
