Are you struggling with a leggy houseplant that has lost its lower leaves? Or maybe you have a tall plant that has outgrown its space? If so, air layering is a technique that can help save and propagate your plant.

Air layering is a propagation method commonly used on older plants that have become woody and difficult to propagate through other methods. It allows a cutting to form roots while still attached to the parent plant.

This technique minimizes the shock to the cutting and maximizes success. In this article, we will guide you through the air layering process step by step, so you can rejuvenate your leggy houseplant and create new plants.

What is Air Layering?

Air layering is a propagation technique that encourages a cutting to form roots while still attached to the parent plant. This method is especially useful for older plants that have become woody and hard to propagate through other means.

By air layering, you can create new plants that are genetically identical to the parent plant, ensuring that you can continue to enjoy the same characteristics and traits.

Materials You Will Need

Before you begin the air layering process, gather the following materials:

  1. Sphagnum moss: This will serve as the medium for the roots to grow into.
  2. A bowl of water: You will soak the sphagnum moss in warm water before using it.
  3. Scissors: You will need them to make incisions on the stem.
  4. A sharp knife: This will be used to make a clean cut on the stem.
  5. Garden twine or a thick string: This will be used to secure the plastic wrap.
  6. Rooting hormone: This optional but can help speed up root formation.
  7. A toothpick: You will use it to prop open the incision and apply rooting hormone.
  8. Clear plastic wrap: This will be wrapped around the moss to create a humid environment.
  9. Your plant: Choose a mature plant with a woody stem that you want to propagate.

Step 1: Prepare the Sphagnum Moss

Take a handful of sphagnum moss and soak it in warm water for a few minutes. Squeeze out the excess moisture so that the moss is damp but not dripping wet.

This will create a favorable environment for root growth.

Step 2: Make an Incision

Using a sharp knife, make a clean cut about halfway into the stem of your plant. The direction of the cut doesn’t matter, but some people prefer to make a perpendicular incision, while others prefer an angled cut.

The incision should be deep enough to expose the inner tissue of the stem.

Step 3: Prop Open the Incision

Before propping open the incision, you can optionally apply rooting hormone to promote root formation. Dip the tip of a toothpick in water and then in rooting hormone.

Gently apply the rooting hormone to the incision. Insert the toothpick horizontally into the incision to hold it open while roots develop. Cut off both ends of the toothpick to prevent it from puncturing the plastic wrap later on.

Step 4: Wrap with Sphagnum Moss

Take the sphagnum moss that you soaked in water and squeeze out the excess moisture. Wrap the moss around the incision, ensuring that it makes good contact with the cut surface.

Gently squeeze the moss into a ball around the stem to hold it in place.

Step 5: Wrap the Moss With Plastic Wrap

Take a piece of clear plastic wrap and wrap it around the moss-covered area. Make sure to wrap it tightly to create a humid environment for root development.

Secure the ends of the plastic wrap with garden twine or a thick string, tying them firmly but not too tight to allow room for growth.

Step 6: Wait!

This is the hardest part of the air layering process – waiting for the roots to develop. It may take several weeks or even months for the roots to form.

Be patient and resist the urge to check on the progress too frequently.

Step 7: Separate the Cutting and Pot It Up

Once roots have formed and are visible through the plastic wrap, you can proceed to separate the cutting from the parent plant. Use sharp scissors or a knife to cut below the rooted area.

Remove the plastic wrap and gently untangle the roots from the moss. Plant the cutting in a pot filled with well-draining soil, ensuring that the roots are covered.

Step 8: Care for the New Plant

After potting up the cutting, treat it like any other newly propagated plant. Place it in a bright location, but shield it from direct sunlight initially.

Water it regularly, keeping the soil evenly moist but not soggy. Monitor the plant for any signs of stress or disease, and adjust care accordingly.


Air layering is a fantastic technique for saving and propagating leggy houseplants. By following the steps outlined in this article, you can revive your plant, create new plants, and continue to enjoy the beauty of your favorite specimens.

Remember to be patient, as the air layering process takes time, but the results will be worth it. Give your leggy houseplants a new lease on life with air layering!
