How do you marcot plants?

Marcotting, also known as air layering, involves inducing roots to form on a plant while it is still attached to the parent. To marcot a plant, select a healthy branch and make a circular cut around the stem, removing a strip of bark about 1-2 inches wide. Apply rooting hormone to the exposed area, then wrap it in moist sphagnum moss and cover it with plastic wrap to retain moisture. After a few weeks to months, roots will develop, and the new plant can be cut from the parent and potted.
