Thanks for the info. Beans are one of my favorites to grow. Grows fast and is pretty easy. One thing I have noticed with my bush beans is that the first couple of pickings are great but after that the beans seem to be tougher and a bit more bitter. I try to pick them before the seeds get to big but they still seem that way. Is that normal? Maybe it's just the heat and less moisture in them as the summer wears on?
