Are your tomato flowers falling off before they can pollinate (that's one problem), or are they just not forming at all (that's another problem)? On your eggplants and tomatoes, you might try flicking the flowers with your finger. That will shake pollen off, and helps pollination. Not sure where you are (you really need to tell us that), but if the heat is on tomatoes and to some extent eggplants won't pollinate at all. Where I am, in Central Texas, tomato pollination is all done for the season. Of course, we started picking in early May!

Sorry, I used to be LindaT. with all my info listed. Here's the info that should have posted. I am in Maryland, zone 7a. I'm gardening in planting tables now. I have planted into garden soil and cow manure. The plants are growing very well but not producing. We had gorgeous lettuce crop, very plentiful. We switched crops from last year, reversing tomatoes, cucumbers, squash to the lettuce table, replaced half the soil with more cow manure. Growing depth is about 16 inches but I can measure if more info is needed. I haven't fertilized. Thanks for responding.

We had a very cool spring, lots of rain and lots of dark, gray days. Now it's suddenly hot and very humid. I'm not losing flowers. Dying after blooming with no tomato attached.

If we're talking about tomato flowers while hot and humid, if the daytime temps are in the 90s, and nighttime temps are in the 70s, no pollination will happen. It's over. Tomatoes don't fruit when the temperatures are high. Ideally, you'd get pollination to happen when it is cool, and then the fruits will mature nicely even when it is hot.

It's definitely not the weather. Also in Maryland and my tomato plants are doing very well. None ripe yet but it's still too early based on when they were planted. Plenty of green tomatoes hanging out though. They didn't put out any new ones for about a week and a half while it was very warm but they are now. Linda, I wonder if your plants are getting too much nitrogen. Could it be the cow manure?

Where do you live? What are your watering and fertilizing practices?

Tomatoes and eggplant can self-pollinate, so it's unlikely to be a lack of bees.

replaced half the soil with more cow manure .... Why?

lazy, I thought since watering table soil it would wash out lots of the nutrients in the soil over a full season. Thought it would be better to replenish my soil.

Do you have a picture of your set-up? It sounds like your soil is quite heavy if you used garden soil and cow manure. A planting table would be like a really large planter, and planters usually require a much lighter soil than growing in-ground.
