Hyacinth beans not flowering or have pods

Question

My hyacinth beans is a huge health vine but no flowers or pods. Any explanation?

Answer 1

There is likely too much nitrogen in the soil. This can be offset by adding potassium and phosphorus. Potassium phosphate is the easiest way, but any bloom formula will do just fine.

This can happen in fertile soils high in nitrogen. Beans produce their own nitrogen from the atmosphere, so any extra will inhibit flowering.
