International Bonsai Master Mauro Stemberger has a new video out titled “Caliandra Spinosa Museo Do Bonsai“. Maruo is in Brazil where he is working on a species very similar to a Bottlebrush Bonsai. The tree has lots of branches which need to be thinned out and Mauro does an excellent job of explaining what to do with a tree like this one. I  have a new page for the species Caliandra Spinosa under Deciduous Bonsai and Bonsai Tree Information pages.
