How to Prune Bonsai Plants

Overview

Caring for a bonsai is an art form. It is an attempt to grow and train a plant in a container to look like an old tree that has been shaped by time and the elements. The process takes time and patience. Bonsais need special care to keep a shape and form that aims for the proper look. Most bonsais are hardy and like being outside during the growing season. They need to be placed in a sheltered area with bright indirect light.

Step 1

Examine your plant and decide on the shape that you want to train it into. It may help to look at similar trees pictured in nature.

Step 2

Cut branches that are rubbing, crossing or damaged. Use a sharp pair of pruning shears to prevent damaging your bonsai.

Step 3

Pinch off new unwanted growth throughout the growing season. This will keep your bonsai in shape.

Root Pruning

Step 1

Remove your bonsai from its container every 4 to 5 years before the spring growth starts. Let the roots dry out a little.

Step 2

Gently loosen the roots away from the soil. Only work on the outer third of the rootball.

Step 3

Prune the roots in the outer third of the rootball. Remove about half of the roots in this section by thinning the amount of roots.

Step 4

Replant the bonsai and resume your normal care of your bonsai.
