pole lima bean fruit setting problem
I live in northern Delaware. What is causing my pole lima beans to not set fruit? I have 2 rows 40' long and 5' between rows and 3' between plants trellised to 6'. The vines are thriving but I see very few pods. Around 99.9% of the flower stalks are without fruit. The only pests I've seen are a few green stink bugs. I'm not having problems with fruit production on my tomatoes, peppers, sun flowers, or adjacent row of string beans. HELP!!
