How to Air Layer Your Plants

In order to air layer, wrap a wounded part of your stem in moist sphagnum moss.

  1. The stem should be wounded below the node using an upward 1-inch slash. Hormone rooting compound can be applied to the surface of the wound if you choose.
  2. Wedge a small piece of wood into the cut so that it does not close
  3. Wrap the moss around the cut and secure it with string or twine.
