Those toilet paper roles always seem to get moldy. Also, what would I use as the bottom? I don't want to tape a cardboard circle to the bottom because then I am putting tape in the garden soil. I thought of brown paper bags, but that sounds like a recipe for disaster if it rips open.Why not follow the concept of a toilet paper roll pot except make it with a larger strip of cardboard instead?
I'm wondering now if I use a mesh plastic basket and line it with paper if that would work. I would plant the whole basket and just remove it at the end of the season when clearing the vines. The roots should be able to grow right through it I think.
