I planted my first batch of Blue Lake bush beans on 5/12/2015. They were very productive. But the production has dropped to very low since about 10 days ago. I'm not sure if they are done for the year, or they will produce again. The few beans I picked today are short, but with large heads. The leaves are dark green.

My 2nd batch has come to full production just now. The pods are long and the leaves are light green.
