No, I do not think so. It even got down to 59 here a couple of mornings ago and mine look fine and continue to put on little tomatoes.

I do not know of much that would cause tomatoes to drop off a healthy plant, perhaps one that got way too dry, but they would be so obviously wilted that you would have been sure to notice. I would wonder if some bird or critter may have picked them off and dropped them or knocked them off. Any indication that the plant or stems are damaged in any way?
That has to hurt to find the little ones on the ground.

That is just my .02 perhaps someone else may have experienced that problem.

Could be incomplete pollination. Or the cool temp affecting a variety different for Bill's. But my first guess is incomplete or lack of pollination. Try shaking the plant to help pollinate the blossoms.

Have you noticed any pollinators around?

Good Luck,

It could be in the genes. Many varieties have the Jointless gene. The slightest wind can separate them, as well as just about anything brushing up against them.

Thanks for everyone's input. We've had nice rains a couple of times a week so moisture is not the problem. A few branches were broken on other variety by wind last week but none on the Grape toms.

There are always bees about & no damage otherwise. I'll be watching those birds.

Here's hoping they quit dropping. Tomatoes can be funny at times.
