Scarlet Runner Beans

Lots of flowers on the bean plants now and the trellis is covered. But the plants are taking a beating in the high heat and wind. The leaves sustain lots of damage from constantly rubbing up against one another. I think part of the problem is my decision to use heavy cord for support. It sways around too much in the wind. Perhaps using poles that are fixed to the frame would prevents the plants from moving around as much.
