Wow! Your plants are way bigger than mine, and I am also in zone 8. We just have too many problems with poor soil, lack of water, and wildlife that eat everything...:/
It's interesting that your pole beans are doing so well, because we can only grow those here in winter. They just burn up in the summer sun and won't produce.
I planted April 4th - Easter Sunday. I planted everything from seed except tomatoes and peppers. I started several tomatoes from seed but only 5 Brandywine and 1 Creole made it. My pole beans are just now starting to get flowers.
