I do not know what went wrong this summer but both my tomatoes and my s-i-l's have

1. Howdy. Tomatoes should flower regularly unless the nutritional needs are at odds with

what is being supplied by the soil - it could be that the flowers are dropping because the temperature/humidity isn't correct for the variety to set fruit when it blossoms. (Cherry tomatoes are much more forgiving, large fruited ones more specific - and pollination of flowers/fruit set is worse when 90 or above and very humid).

Bees are not at all essential for tomatoes to form - the flowers have both female and male parts and the deed is typically done as the flower opens. (Bees actually cause issues for seed savers growing non-hybrids because they can spread pollen from variety to variety and create unwanted hybrids).

What's your weather been like - and which varieties are you growing? Seasonal weather has such impacts - last year was my worst tomato crop in 20 years, this year is one of the best.
