Propagating your Poinsettias

Poinsettias (Euphorbia pulcherrima) are plants known for their vibrant red and green foliage and are usually popular in the winter and around Christmas. They are one of my favourite plants and I currently own one that is over four years old. I often feel very sad when I see them in shops or garden centres because they are often hot housed to be be bright red in time for the Christmas season, but people don’t know how to care for them, and they die and are thrown away.

While they are often purchased as potted plants during the festive season, many enthusiasts enjoy propagating them to create new plants. Propagating poinsettias can be a rewarding gardening endeavor that allows you to expand your collection or share these colorful beauties with friends and family. Here’s a step-by-step guide on how to propagate poinsettias successfully:


1. Choose the Right Time: The best time to propagate poinsettias is during late spring or early summer, after the winter holiday season. This period provides the ideal growing conditions for new plants to establish their roots and thrive.

2. Gather Supplies: Collect the necessary materials, including a healthy poinsettia plant, clean and sharp pruning shears, rooting hormone (optional), well-draining potting mix, small pots or containers, plastic bags or a propagator, and water.

3. Select the Cuttings: Choose healthy stem cuttings for propagation. Look for non-flowering stems with at least 3 to 5 inches in length. These cuttings should have several sets of leaves and no signs of disease or damage.

4. Prepare the Cuttings: Using clean pruning shears, make a clean diagonal cut just below a node (the point where leaves are attached to the stem). Remove any leaves from the lower portion of the cutting to prevent them from rotting when buried in the soil.

5. Apply Rooting Hormone (Optional): To encourage faster root development, you can dip the cut end of the stem in rooting hormone powder. This is an optional step but can improve your success rate.

6. Potting Mix and Planting: Fill small pots or containers with well-draining potting mix. Make a small hole in the soil using a pencil or your finger and insert the cutting, burying it about 1 to 2 inches deep. Gently firm the soil around the cutting to hold it in place.

7. Watering: After planting, water the cuttings thoroughly but avoid waterlogging the soil. Allow excess water to drain away, as overly wet conditions can lead to rot.

8. Create Humidity: Poinsettia cuttings benefit from high humidity during the rooting process. Place a clear plastic bag or a propagator over the potted cuttings to create a humid microenvironment. This helps prevent excessive moisture loss through the leaves and encourages root growth.

9. Provide Indirect Light: Place the potted cuttings in a location with bright, indirect light. Avoid direct sunlight, as it can scorch the cuttings. A north-facing windowsill or under fluorescent lights are good options.

10. Monitor and Transplant: Check the cuttings regularly for signs of new growth and root development. After a few weeks, you should notice new leaves emerging. Once the cuttings have developed a healthy root system, typically after a few months, you can transplant them into slightly larger pots with regular poinsettia care.

11. Gradual Acclimatization: Before moving the propagated poinsettias to their permanent indoor or outdoor locations, acclimate them gradually to changes in light and temperature. This helps reduce stress and ensures a smoother transition.

12. Care for Your New Poinsettias: Once the propagated poinsettias have established themselves, provide them with proper care, including regular watering, well-draining soil, appropriate light levels, and occasional fertilization.


By following these steps, you can successfully propagate poinsettias and enjoy the beauty of these colorful plants year-round. If you learn how to care for them, you will have happy, healthy, beautiful plants that will be a feature at Christmas but also saved from certain death in the new year too.
