Growing tomatoes can be economical and fun, but it can be frustrating when the plants develop problems. Many times it is disease related but occasionally it is due to growing conditions. Keep in mind these may occur on peppers, too. This is a common disorder called blossom end rot. It is caused by a calcium deficiency with-in the fruit.

Pick and discard all affected fruit to allow the plant to keep producing blooms and new fruit.

Blossom End Rot - The bottom of fruit develops a brown leathery skin. This is due to a calcium deficiency during fruit development.  Generally the problem is not insufficient soil calcium levels but rather inadequate soil moisture preventing calcium delivery to the plant. Consistent irrigation is the control. Mulching the plants will help with soil moisture consistency.
