Hello. I have a acer palmatum winter flame that is a grafted tree. It is about 5 years old, and i am wanting to do an air layer to get the real tree with no graft scars. Which would give the best results? 1) Let the parent tree's branch to layer get to the size wanted then layer, or layer and let it grow on its own? I guess if was layered and grown on its own it would develop a better nebari quicker. Which would give you the largest caliper trunk quickest?
