what causes rotting on the bottom of tomato still on the vine?

Question

I went to pick some of my red tomatoes (Early Girl) and they were rotted on the bottom of the tomato about half way up.  What might be the problem?  Most of the others on the plant look fine.

Answer 1

The problem with rot on tomatoes or peppers is called blosoom end rot and to solve the prpblem  your plants are lacking calcium

Answer 2

this sounds like blossom end rot.  It is due to inconsistent watering that does not allow the calcium in the soil to be released to the plant.  There are sprays to overcome this or you can correct your watering.  Water only if the leaves look wilted in the morning.

Then water deeply.  If you have trouble telling if the leaves look like they are wilting then stick your index finger in the soil about six inches from the plant.  If the soil is dry two knuckles down, then water deeply.  Deeply and infrequently is the best way to water for good tasting tomatoes.  Usually once every three or four days.

Answer 3

This is blossom end rot which is caused by a calcium deficiency.  Water your plants with liquid calcium and you will see the problem cleared up by the next picking.  For future years, you can help to prevent this by saving egg shells and crushing them up and placing them in the holes around the roots when you plant your tomato plants.
