I planted this chocolate vine, hoping to give my dogs some shade in their potty area. It is doing great. We have one of those black tarps on top to act as sunblock. I am wondering if you think it will grow on the tarp, or do I need to put some lattice up there? I don't want it completely covered, just that back corner. In the second picture you can see where it's ready to go over the top, I'm just wondering if it needs something to twine around??
