With more work on this root, using a knob cutter relegated to below-ground carving, I’ve taken a lot of the “weight” off and this will make the root a lot less obtrusive.
You may be asking, Will this harm or kill the root? No, the root will not only continue to do its thing, it’ll heal over vigorously as this is a characteristic of Cedar elms.
I really like this elm bonsai. The design is unusual (something the tree did more or less on its own when it was rebudding), and elegant. The twigging will increase this year, and leaf size will reduce nicely.
I’d love to hear what you think of today’s work.
