Hi Hareth - It's called blossom drop - a common problem. The link below is to the FAQ on it and discusses the causes and remedies. If you search using that term you will find many discussions about it to review for tips and info. ;)

check super good for Tomato Horn Worms. They are nearly invisible in the foliage.

I think they were eating off the leaves around my blossoms and killing them. Got'em though!

Thanks for the replies. Blossum drop seems the mostly likely cause but yet to find out the specific reason.

Heat is generally the #1.

Not only did I by tomato plants with blooms but I got 3 so far and now no more. There is also white flat worm like things on the leaveas. Between the blossom drop and white flat worms, I'm mad. I bought the soil at Lowes, and put the two plants in a big container. I'm going to go back to Lowes and see what they say but in the mean time, any help would be appreciated. Thanks.
