Oh wow. It's gorgeous. I've got a willow oak in a pot I've been growing for a few seasons that I've thought about trying this on, but haven't progressed past the "having YouTube playing bonsai videos in the background" stage yet. Beautiful plant
Thanks! YouTube videos are certainly helpful and that's where I've gained most of my knowledge. The other best way to learn is to join a local bonsai group. You can probably find one on Facebook if you look. I haven't worked on Willow oak specifically yet, but let me know if you have specific questions :-)
