Can Clematis climb this?

graficaamy(6)June 18, 2013

I have a group of clematis that I rescued from the compost at a nursery where I worked last year. Only a few have ID (Betty Corning, Henryii), while the others are mysteries. Do they stand a chance of climbing up my 5' aluminum fence, which has straight 2-1/2 inch square posts, with straight 5/8-inch square pickets, and 2 horizontal rails at the top? I.e. will they get enough "traction" to climb up the metal pickets, or do I need to rig up some netting or twine to get them to climb?

IME they need something less than 1/2" diameter to cling to since the leaf stems (petioles) wrap around the supports to allow the clematis to climb. Plastic netting is difficult to remove the dead vines from IME, so I tend to use narrow metal supports like 3/8" rebar, metal cable, or wire mesh fencing with at least 2" spacing. Compostable string would work as well since you could just cut the vines and remove them with the strings. Fishing line needs knots to keep the vines from sliding down.
