Do you pinch Sweet Autumn clematis or just prune down low in spring? This is my first Sweet Autumn and I did prune, but don't then if you still have to pinch.
Cathy..nope..you hard prune him in early Spring down low like you did and that is all..he will grow & grow and BOOM in late Summer Early Autumn his beauty and scent will take your breath away....Jeanne
That's kind of what I thought :)
I just wasn't sure.
