I'm having some trouble with blossom drop on several of my tomatoes. I'm a novice so I haven't a clue what to do. I do have fruit on all the plants that are having this problem & we're in the midst of a drought & temps in the 90's. I've been watering however. Some are container grown & some in the ground. I remember reading that some of you use epsom salts on your tomatoes, but don't remember if this is one of the situations that call for it.. Thanks for your help. Kim
