I have prolific beautiful disease free butter and Loma beans. Prolific blooms,, but light yields.. I did not fertilize this year –
same result.. Is this normal?? I plant seeds 1ft apart, and grow on 6ft trellis - they become a thick mass of vines & runners with few beans.

It sounds like there is too much nitrogen in the soil. If you feed beans, you should only feed them potassium and phosphorus. This will help with bean production. When it starts getting above 80, beans will almost stop producing all together. You can get around this by planting in shade during the afternoon during the hot season.
