I'm pretty sure my tomatoes are getting blossom end rot, the bottom half of the immature fruits are turning black. So far, only the smallest tomatoes on the ends of each bracket(???)/brace/cluster/group are affected. This year I used 120 pounds of dolimitic lime on the 30'x90' plot, hopeing it would prevent this problem. That was the rate suggested on the bag for my soil conditions to bring my pH to 6.6. The water is also extremely hard so I was hoping that would help. Now that the plants are in the ground, is there anything I can do to get calcium to them ASAP? Could the rot be from something other than lack of calcium?
