Too few flowers on tomato plants
My tomatoes do not seem to be getting enough flowers. They are in the same location as last year and I got lots of fruit. I had blossom rot early last year, so this year I fertilized with 7-4-5 Happy Frog fertilizer. I pinch off a few leaves that look bad every so often. Last year I planted all Roma. This year I have Roma, Whoppers, Season Start and Chocolate Cherry. All seem to not have enough flowers. I'm in Chicago. My peppers seem to be doing fine. We've had crazy rain and temperature swings this year.
Should I trim away more leaves? Does anyone have a suggestion?
Thanks in advance - Krounded.
