The Badger Bonsai Society had bonsai artist Roy Nagatoshi visit for a demo on boxwood, and two days of bonsai fun filled days of workshops.
I took too many pictures to post here so if you want to see that use the links below.

One thing that I learned from Roy was the use of Lysol disinfectant on cut areas, and he said that on most species that is all you will need.
