If you have enough moisture to get them out of the ground. And if they do grow they get a foot tall cause they will no longer grow after about August 20 "Has to do with daylite hours" they may make 10 bushels if all is right. But if it is and stays dry you are wasting seed, fuel, machinery and time. Lot of ifs.
They will try to grow longer but just get frosted off before full maturity. You will have green dry beans about the size of a bb. I wouldn't have made all these comments but your the one that said you were a fruitcake. Sorry.
They tried some beans after wheat here about the 1st of July. Went by them last week and they were 3 inches tall and very thin stand.
Here I am wondering if my May 10 beans will make anything because of drought.
