The Q&A Archives: Tomato Blossoms Die

Question: I bought heirloom seeds (Mortgage Lifter, Anna Russian, Abe Lincoln, and the plants grow and produce many blossoms but never turn into tomatoes. They just turn brown and die. Is there some sort of pest doing this?

Answer: Usually blossom drop is caused by lack of pollination and/or poor weather conditions -- days or nights too hot or too cold, too much rain, too windy, to dry, too wet and so on. Since we can't control the weather, you might try shaking the plants about once a day to promote pollination and possibly a commercial "blossom set spray" would help.
