Blossom end rot is a black, sunken area at the blossom end of tomatoes or peppers. The blossom end is the end of the fruit opposite the stem. Blossom end rot is most often seen on green fruits, usually the first fruits to appear on the plant.
Blossom end rot is caused by calcium deficiency in the fruit. That deficiency can be caused by a lack of calcium in the soil or the plant's inability to draw up calcium from the soil--most often caused by a lack of water. Blossom end rot is aggravated by drought or uneven soil moisture. Soil moisture taken up by plant roots delivers calcium to plant cells or by the excessive application of fertilizer, usually nitrogen or potassium.
