How to Grow a Poinsettia Tree? Poinsettia Topiary
How can I grow a poinsettia tree like the one in the picture.
You can’t use a poinsettia plant that you currently have to make a poinsettia topiary, the correct name for a poinsettia tree. A poinsettia topiary has only one stem/trunk and I’m sure your poinsettias have multiple stems. Here are some instructions how you can create a poinsettia topiary.
1. Take about a 5″-6″ stem cutting from a poinsettia plant leaving a few leaves on the stem and root it in some good potting soil. keep the cutting in medium light.
2. Once the poinsettia has rooted move it to bright indirect light.
3. As the plant grows keep removing any side shoots or stems but leave the main stem alone.
4. Once the plant is as tall as you want, start allowing the the side stems that develop along the top 1/3 of the stem to remain. Pinch back these side stems often so that the canopy of colorful flowers (really bracts) will be full and bushy. Stop all pruning by November.
