Propagating a Snowball Bush by Air Layering: A Reliable Method for Woody Shrubs

Want a clone of your parents' gorgeous snowball bush? Air layering is the most dependable way to root woody shrubs. In spring, select a pencil-thick branch, wound it by removing a 1-inch ring of bark, and wrap the wound with moist sphagnum moss sealed in plastic. Keep the moss damp for about eight weeks.

Roots will form at the wound site. Then simply cut below the new root ball and pot it up. You can start multiple layers on the same donor plant without harming it. It's low-risk, high-success propagation that preserves the exact characteristics of the parent.
