Q.Why are my tomatoes not producing
Last year at this time I had hundreds of tomatoes. This year I am getting 1 to 3 tomatoes per plant. They were fertilized and are watered regularly just as last year. The plants are very large and have buds everywhere. I have not seen any bees but never saw them last year. The plants look good but just are not producing. Any suggestions?

The warm weather and lack of pollination can both be factors.
