I have nice tomato plants but the blossoms seem to fall of.

My plants are the nicest I have ever had but just 2 or 3 tomatos.  I have lots of blooms then nothing.  I am sure I am doing something wrong.  I need HELP!.  Thank you one and all  Harrison

Try hand pollinating them with a paint brush or electric toothbrush attached to a baggy. Could be multiple things but if the fruit isnt even setting I would think they are not getting pollinated. Good luck!

What are the temperatures like?  Is it outdoors or in a greenhouse?  Tomatoes need cooler night time temperatures in order to set fruit and here in FL in the heat of summer many larger type of tomato plants will quit even setting blooms.  If in a greenhouse pollination could be an issue as well as temperature.

 

Is it a new system?  Sometimes a lack of potassium will keep plants from flowering and fruiting in a new system and seaweed extract can help that.

thanks tcl I will try all you said.  where is the best place to get the deaweed extract? Harrison

I'm not sure of the best place to get seaweed extract.  Maxicrop is actually pretty hard to find locally here and I get it from a major distributor so I have to buy it a case at a time.  Check around at local garden centers, you are looking for extract with the NPK numbers close to 0-0-1  Or  0.1-0.0-1.0  If you can't find it locally, the shop tab here will take you to Sylvia's store and she sells it.
You could check with your local hydroponic store if you've got one.  My local one had no problem special ordering for me.  Saved me shipping...
I have a six foot tall tomato plant with flowers on it but it isn't putting out right now. It's way too hot. I am getting a couple of cherry tomatoes but only ones inside the plant where the direct sunlight isn't hitting the flowers and fruit. We are getting some tomatoes off the square foot gardening but again it's on the on the inside of the plants were the sun isn't getting.
try covering them in some sort of shade netting possibly.
