|Why does my tomato plant keep producing lots of blossoms, but none ever mature into fruit?|
|Tomatoes like heat but not too much. Nighttime temperatures above 75F and daytime temperatures above 100F causes blossoms to drop; some tomato varieties are more susceptible to this blossom drop than others. If your weather has been particularly warm, this could be the problem.
Water the plants as necessary to keep the soil moist and mulch with a thick layer of straw or hay. This mulch will help conserve soil moisture and keep soil temperatures from fluctuating too much. If the plants look healthy otherwise, then I would wait and see if the next round of blossoms start developing fruit.
Next year, consider trying heat resistant varieties such as Heat Wave that set fruits even in the hot weather.
