Wisteria climber for container
I have a 6 x 20 feet stone wall and would like to grow a wisteria climber along it. At the base is a paved drive. So my plan is to grow from a container but will this offer sufficient root development space? Would I need more than 1 plant?
You certainly won't need more than one plant. You should use as large a container as you can find - something like a half barrel would probably work. Wisteria is such a vigorous and long-lived plant that containers can be problematical. You could look into miniature wisteria - that might even work better.
