Tomato Blossom Drop

If your tomatoes are dropping blossoms or the flowers wither and die, there are several reasons, all of which are related to stress. The stressors can be environmental, nutritional, or a combination of the two.

Nitrogen: Too much or too little will stress the plant. Always follow the instructions on your fertilizer. Use an organic, slow-release fertilizer and compost instead of using quick-release, synthetic fertilizers.

Temperature: Day temperatures above 90 degrees and night temperatures above 70-75 degrees can interfere with pollination and fruit set. Research indicates that the higher night temperature has more of an influence. In this case, sadly there is not a lot you can do about it

Excessive wind, stress from insects or disease, lack of light, and excessive pruning are also reasons to explore if you’re experiencing blossom drop. Spend some time in your garden and see if you can identify the reason. And if you have any questions, feel free to reach out!
