Thanks. Hrm... I had actually put that bamboo up to be the trellis, which works great for peas and cucumbers, less great for beans and my malabar, which need bigger gaps to twine around. Thus I put the individual bamboo up because I needed something there. lol, gardening on the fly. It isn't very sturdy though, for leaning away from the fence. I'll have to think of a way to make it more solid. If I didn't have it tied to the main trellis right now, it'd just fall over.
And it is north facing, so not really the sunny side. Just in the morning when the sun comes up they get about 5-6 hours of direct sun. I'll see what I can figure out to make them sturdier to stand on their own.
