Did you over fertilize causing too much growth? Side dress them with Epsom salts and some superphosphate (Triple phosphate) to make them bloom. If you can water them you should get beans until early fall.

Everything in my garden is maturing at least a month late this year. I blame the cool spring and the excess rainfall in April and May. My cabbage,broccoli,lettuce and radishes all died from standing water. Got a few radishes, but none of the others. My squash bloomed profusely but put on very few fruits. My bush beans were just mature enough to pick about a week ago, and a few tomatos are just now turning pink.
I tried Blue Lake pole beans a few years ago and found them to be more prolific but less flavorful than Ky Wonder. I found Fortex to be more prolific and more flavorful than Ky Wonder.

this is the first year Ive tried pole beans (Ky Wonder.) not many beans, but I think my problem is not enough sun. i only get maybe 5 hrs of real direct sunlight, maybe less due to all the trees on the edges of my property. Tomatoes and blueberies have done well, but very few beans and green peppers.
They probably want a serious day of full sun to produce.
