Here is a short (seven minutes) video from Jake Hobson, whose book Niwaki is also the name of his business in the United Kingdom.
This is a great thing to watch for those interested in learning a little more about pruning on garden trees.
Jake Hobson offers workshops on pruning. The next one is Tuesday, September 16. For more information, go to his web site and look in the Events category: http://www.niwaki.com/shows/
Another publication by Hobson is The Art of Creative Pruning: Inventive Ideas for Training and Shaping Trees and Shrubs.
