I don't know which pruning group my clematis belongs
I've got a clematis which I have hard pruned in Feb as a group 3, but it has never done well, maybe 2 or 3 flowers. I'd wondered if it was unhappy in its spot, but now wonder if I've pruned it as the wrong group. I thought I would leave it unpruned this year and see what it did. Is this the best idea?
