Blossom End Rot

Blossom End Rot is a common problem with tomatoes and some peppers.  The buttoms of the fruits turn black and soggy.  It can be caused by irregular watering or the presence of too much nitrogen and too little calcium.  Although it tends to be self-limiting,  it can be disheartening.  A 2% calcium chloride and water solution will help.  But as the plant grows it will usually find sufficient calcium and self-corrects.  Tomatoes react strongly to nitrogen.  Add too much and you’ll get beautiful plant and no fruit.  Give them just enough to get a good dark color and then scale back.
