I figure they're too young now, but my next educational mission is pruning for aesthetic purposes and keeping them a manageable size in a container. I'm not necessarily interested in pruning for Bonsai, but I'd assume the technique is somewhat similar, and would like to learn a bit about Bonsai as well.
If you know if any tips, tricks, advise, experiences (good or bad) techniques or links on how to prune JM's, please share!
We do have a bonsai forum here on DG. I take a look over there now and then. I don't recall seeing a lot of JM bonsai advice there but it could be worth a look anyhow.
I have most of my JMs in pots and I do prune occassionally but for the most part I just prune them like I would most other trees - I remove crossing branches or any that grow straight up or straight down. I also like to "limb up" the upright growing JMs I have because I prefer that look to the bushier look.
