Q: My tomatoes have been ripening but the ends have turned black and mushy. What is wrong?
A: I have had a deluge of tomato problems but this one is very common. It is called blossom end rot. The first thing is to be sure the tomatoes are being irrigated on a regular basis. Remember not to over-water but irrigate at the whole root area. Blossom end rot can also be caused by a combination of lack of water and calcium. In addition to watering properly, add calcium to the soil around the root area. Use calcium nitrate but not the calcium found in ammonia fertilizers. Remove the infected fruit but do not be tempted to prune away large portions of the vine. Addition of mulch may also prove beneficial at keeping the root area moist and temperatures at the roots moderate.
