Japanese Maple Sprout Under Large Maple – Prune It

Q: Early this year I found a 4” Japanese maple sprout growing under my large maple. Now it’s eighteen inches tall. It’s only a straight stem with many leaves all along the stem. Do I need to prune it back to get side branches to grow?

A: There’s no need to prune it. The tree will develop its own form over the next several years.
