The blossoms will drop without setting fruit once the temperature goes above 90. There is a product called Blossom Set that you can spray on them that will prevent that.
I didn't know that, Leni! I actually have Blossom Set, but didn't know that I should have used it in mid-June when the weather got so hot and lasted for almost 2 months now, with only a break or two!
Damn! I do have some tomatoes, but not nearly as many as I should, and almost NO new flowers!
Thanks for the tip! I'll use the blossom set every year now, just in case!
