Fruit set in pole beans

Asked June 30, 2018, 2:54 PM EDT

I used to grow pole beans but recently have not been getting any beans just foliage . Bush beans seem to set fine. I tried not fertilizing in case they were getting too much N but still no luck. Any suggestions?

If they appear overly lush it's possible that N levels are too high. If the plants seem normal in appearance, size, and growth habit but are still not producing flowers it could be too early in the season (70-75 days from seeding to harvest) o rapidly fluctuating May/June weather. It's also possible that warming global temperatures and the growing heat sink effect in metro DC are reducing flowering and fruit set. This has been occurring in pepper, tomato, and lima bean. You might want to try removing some lower leaves on some of the plants to see if that encourages flower bud initiation. jt
