Will a clematis cling to these railings?
The railings are plastic and roughly 1.5" by 1.5" square. The vertical beams and the deck flooring are composite. The stained steps are wood as well as the lower, stained, posts. Basically everything that is white is plastic or composite and everything that is brown is wood (except for the platform which is composite too).
I was going to use fishing line tied to little nails as a structure for the clematis to cling to but I can't nail into a plastic railing. Any suggestions? Will clematis cling to those railings? Can you drive nails in to composite board? What could I use to attach fishing line to those plastic railings if the clematis won't cling to them?
