Need more specifics. Are you saying the plants are not even growing flower clusters? or are they growing flower clusters but aborting the flowers/flowers dying?

MY few plants I grew from seed are just starting to take off now. I only have some flowers at this time on the plants I have growing. There are no tomatoes yet. I think they look great compared to last year. Last year something (I think lawn fertilizer drift) stunted the growth and I only had a few tomatoes. The ones I did get were very small. The month of May rains were record breaking here in Chicago and weather was too cool so I am happy they look as good as they do. I am sure they will catch up for you. We must have faith.

Sorry about your low tomato set count and you're spot on, to many cloudy days will cause blossom drop. I'll tell you last year was one of the worst for tomatoes here in twin cities metro area MN that I can remember, and even the local feed mill coop owner said everyone was complaining about their tomatoes last year.

Cloudy all damn summer from spring to fall, my wife even remembers me bitchin about too many clouds, and a lot of rain. All my indeterminate plants had reduced yields and poor quality fruit, and not great taste tomatroes, along with issues such as yellow shoulder and green under the red skin, and white insides from ripening problems. Yield was average for the determinate plants but again low quality fruit.

I researched the problem during the winter and concluded the low fruit count was indeed do to the cloudy summer. The bad tasting tomatoes were caused by my Muck soil, yes officially labeled as muck and to much water. Muck and excess water causing low oxygen levels and problems with uptake and will also effect blossom set.

At first I thought my potassium amount was wrong but I'm an expert on fertilizers and that wouldn't happen.

Look at your main stems, you should have a cluster every 3 branches, if not something was wrong and flowers or entire clusters were aborted because of the clouds, saturated soil or both. I looked at the temp chart in your area for every day of June and nothing that would cause blossoms to drop and and I don't doubt your ability to care for the plants, so with luck the months to come will be better.

They produced clusters and flowers, but most were aborted for the first two or three whorls. After that, they look fairly normal in number of setting fruit.

I do think it was the extremely wet and cloudy Spring we had here in Charlotte.

I just did a rough fruit and blossom count on my celebrities and need to retract what I said about my determinates and (semi) having no reduction in blossoms/fruits last year. I'd estimate a 50% reduction compared to this year. This year the Celebrities have 40+ fruit and 50+ blossoms hanging on each plant and the paste tomatoes are too many to even count.

My cloudy rainy summer lasted all summer last year but with luck yours will clear up.

We have had more rain but my plants are looking so much better now. I looked back at my last post and from 6/23. The plants today are much taller and I have plenty of flowers and some small tomatoes. Now we have to deal with the July heat and humidity and keep them free of viruses and insect damages. I feel this will be a better year. The sun is supposed to be out for a few straight days after 1.5 inches of rain the other night.

It could be weather related. When it's too humid, the pollen doesn't move. If it's too hot or too cold, the flowers won't form.
