trimming back a japanese maple

Asked May 13, 2015, 9:25 PM EDT

We have a nearly spherical cut-leaf Japanese maple which has grown far too large for its space. Is there a method/way to trim its diameter from 6-7 feet to a 4' or so ... All the growth is on the exterior of the plant w/ no leaves or live shoots in the well shaded interior. We have tried to trim the internal dead wood and branches to give more droop - but little happened to the overall size. Thank you

When you prune a Japanese maple, you want to cut branches back to where they join another branch. http://extension.umd.edu/sites/default/files/_images/programs/hgic/Publications/HG84_Pruning%20ornam... You may not want to do all of your pruning in one year. Don't remove more than 25% of the tree in any year. The best time for extensive pruning is when the tree is dormant. http://www.finegardening.com/pruning-japanese-maples vw
