Blue Greasy Grits Question
I'm growing these for the first time, due to weather and circumstances these were planted late this year. They were growing just fine and when they should have been flowering we hit a patch of hot weather. Since it has cooled down they're growing vigorously, flowering like mad and there's lots of small beans forming. Can someone tell me how big they should be to be picked as snap beans, strings are not a problem but would like to pick them before they get tough.
