RE: Why I prefer pole beans over bush beans
I've grown both pole beans and bush beans, and I agree with your points.
In past years, I've grown pole beans because they're easier to pick than bush beans. I had about 24 feet of trellis, so I was inundated with beans once they started getting ripe. I canned a lot of beans that year. They were still flowering at the beginning of October when the frost finally killed the plants. I had to pick a fair amount of them with a step ladder to get to the top of the trellis.
The past 2 years, I've been growing bush beans in raised beds. They're a lot easier to manage in a raised bed, picking is easier also. I also grow the bush beans in big containers. They're easier to pick, but they require more attention to the watering because the dirt in the containers dries out faster than a raised bed or the ground does.
It sounds like you've got your system dialed in well. A raised bed would make bush beans easier on my back and knees. Thanks sharing that.
