I got my first taste of bonsai karma. An older neighbor asked me for some help with his yard and when we were done and had a few beers, he asked if I would mind also removing a stump. So long as I can keep it and he gives me another beer, I was glad to assist. I'm now the proud owner of a fairly thick Norway maple (over 3" at the bottom). This was kind of impromptu, so it ended up in a fairly large box planted in whatever soil I had - a few gallons bonsai jack and lots of bark (and other organic material). Curious to see if it makes it and what it looks like going forward.
