Propagation of poinsettias (Euphorbia pulcherrima) can be done effectively through cuttings. Here’s a step-by-step guide:
1. Choose the Right Time:
Best to propagate in late spring or early summer when the plant is actively growing.
2. Select Healthy Cuttings:
Look for healthy, non-flowering stems. Choose stems that are about 4-6 inches long with several leaves.
3. Prepare the Cuttings:
Use clean, sharp scissors or pruning shears to make a cut just below a leaf node.
Remove the lower leaves, leaving a couple of leaves at the top.
4. Apply Rooting Hormone (Optional):
Dip the cut end in rooting hormone to encourage root development, though this is optional.
5. Prepare the Potting Mix:
Use a well-draining mix, such as a blend of perlite and peat moss or a commercial potting mix.
6. Plant the Cuttings:
Insert the cut end of the stem into the mix, burying it about an inch deep. Firm the soil around the cutting.
7. Watering:
Water the cuttings lightly to settle the soil. Make sure not to overwater, as this can lead to rot.
8. Create a Humid Environment:
Cover the pot with a plastic bag or a clear plastic dome to maintain humidity. Ensure there’s some airflow to prevent mold.
9. Provide Adequate Light:
Place the cuttings in a bright, indirect light location. Avoid direct sunlight, which can be too harsh.
10. Monitor and Maintain:
Check the cuttings regularly for moisture and remove the cover for a few hours daily to prevent mold.
11. Rooting Time:
After about 4-6 weeks, gently tug on the cuttings to check for resistance, indicating root development.
12. Transplanting:
Once rooted, transplant them into individual pots with a standard potting mix. Continue to care for them as you would for mature poinsettias.
13. Care for Young Plants:
Water when the top inch of soil feels dry, and provide bright, indirect light. Fertilize every few weeks with a balanced fertilizer during the growing season.
