Can't wait to see how these develop. My first year in bonsai (four years ago), I dug a neighbor's leafed-out pumila that would have taken over his driveway, eventually. I managed to kill it in short order. Didn't know about modern substrates at the time, guess I just "noobed" it to death! There's one growing wild in my neighborhood that I want to air layer next year (couldn't do it this year due to inoportune timing of vacation). The biggest criticism I've heard about them is that they can drop branches.
