Planted more bush beans

I planted some more bush beans. I planted some stringless green beans and some waxbeans. The first time I planted them, they did not produce very well and they were planted four to a square so I tried planting 9 to a square so I may be able to harvest a little more. I beleive they will still have enough room. There are still some beans on my plants but not that many. My pole beans are a different story. I will have plenty of those.
