I have made a page for Viburnums and another page for Viburnum Inter-Node and Leaf reduction technique. I believe this technique can be used on any type of Viburnums. I have 6 years of experience using this technique and it does a nice job on both. The new Viburnum page is listed under Deciduous trees, shown in Tree Information page. It is also listed under the Ramification page on the Bonsai Basics page.
