bean blossom drop

Asked April 2, 2013, 2:07 PM EDT

My table beans, both bush and perhaps even more so with the pole beans, seem to have many blossums, but far fewer with fruit setting on. It seems that the majority of the blossums sit on for a while and just drop off, without producing beans. One gardener told me that was because of excess heat last summer, but this blossum drop afflicted plants grown in cooler parts of the garden too. I thought iit might be some insect that only attacked at night, but maybe soils/nutrients? Something else? thank you!

Heat, wind, dry soil and low humidity all can result in bean blossom drop. Beans are VERY sensitive to these conditions during blossoming.More detail in bean section at
