Root Pruning an Umbrella Tree to Keep It in the Same Pot

Controlling Size by Pruning Roots, Not Just Branches

When an umbrella tree (Schefflera) sends roots out of the drainage holes of a 15-inch pot, you don't necessarily need a larger container. Root pruning—similar to bonsai techniques—can keep the plant healthy and compact in its current pot.

How to Root Prune and Repot

1. Remove the plant from its pot (best done if it hasn't been repotted in a couple of years).
2. Gently wash old soil from the roots.
3. Trim the root mass so it fits comfortably back into the same container with about an inch of fresh soil around the sides.
4. Have a helper hold the tree upright while you fill in with new potting mix.
5. Water thoroughly, let the soil settle, and add more if needed.

Aftercare

Place the tree in a shady outdoor spot for a few weeks to recover. It will often rebound with vigorous, healthier growth than before.
