I recently bought a Viridis Japanese Maple and I wanted to prune the bottom of the 3 foot tree, I noticed the main good size branch at the bottom, which weeps downward is the scion that was grafted on. The larger straight up portion looks very nice but I assume looking at a small akane seedling that I bought and the root stem was cut off, that the larger section is root stock from a Viridis maple , can I cut off the scion graft?, it is right on the ground. I am going to add a couple of photos to this previous post, to show the low scion ( I believe) can this low portion be trimmed off close to the trunk?
