Propagation Techniques

If you wish to propagate your poinsettias or start new plants from cuttings, there are a few techniques you can follow:

  1. Stem Cutting: This is the most common method of propagating poinsettias. Begin by selecting a healthy, non-flowering stem from the mother plant. Use clean, sharp pruning shears to cut a 4-6 inch section of the stem just below a node (the point where a leaf is attached to the stem). Remove the lower leaves, leaving only 2-3 at the top. Dip the cut end in a rooting hormone to encourage root growth and then plant the cutting in a well-draining potting mix. Keep the soil moist but not saturated and place the cutting in a warm location with indirect sunlight. After a few weeks, the cutting should start to form roots, and you can then transplant it into a larger pot.

  2. Air Layering: Air layering is another propagation technique that is suitable for poinsettias. Select a healthy, non-flowering branch and make a small cut through the bark, about 1/3 of the way through. Apply a rooting hormone to the cut and then wrap it with a moist sphagnum moss. Cover the moss with a plastic wrap and secure it tightly with a rubber band. After a few weeks, roots should develop above the cut. Once the roots are well-established, you can cut the branch below the roots and plant it in a pot.

  3. Division: Division is a method of propagation that is most effective when the poinsettia plant is dormant. Gently remove the entire plant from its pot and carefully separate the root system into sections. Make sure each section has a good amount of roots and leaves. Plant each section in a separate pot with fresh potting soil. Water the newly divided plants thoroughly and place them in a warm location with indirect sunlight. With proper care, these divisions should grow into healthy poinsettia plants.
