My tomatoes blooms are falling off as they set.
It called blossom drop. Google for more info but basically it means your plants are stressed. It happens to me in the heat of the summer but I believe cooler weather does it too.
Thanks, I have since found out what's going on with my tomato plants. The recent rains have caused Blossom In Rot in washing away the calcium. I hope the spray I purchased helps.
i do not think it is blossom end rot. Blossom end rot usually appears on developing tomatoes and looks like the brown/rotting area on the bottom.
