What should I do to stop tomatoes from rotting on the vine?

The characteristic indication of blossom-end rot is a water-soaked patch at the blossom end of tomato fruits. This frequent garden issue is not a sickness, but a physiological ailment caused by a calcium imbalance inside the plant. It may be found in the fruits of peppers, squash, cucumbers, and melon, as well as tomatoes.

Blossom-end rot is most common when the growing season starts out wet and then becomes dry when fruit is setting. The earliest signs of damage show when the fruits are about half their maximum size. Water-soaked patches expand and become dark brown and leathery. These areas will eventually begin to rot, so the fruit should be picked and discarded.

A plant’s capacity to absorb adequate calcium for healthy growth might be hampered by a variety of reasons. They include soil moisture variations (too wet or too dry), an overabundance of nitrogen in the soil, root damage caused by cultivation, soil pH that is either too high or too low, cold soil, and salty soil.


Prevention and Control

  • Keep regular soil moisture levels throughout the growth season. Water thoroughly once or twice a week when the weather is dry to hydrate the soil to a depth of at least 6 inches. Drip irrigation systems or soaker hoses are great for this.
