Just like other poinsettias, the poinsettia tree requires bright sunlight to thrive. Place your tree in a sunny spot near a window where it will receive at least six hours of direct sunlight each day. Be sure to rotate the tree every week or so to prevent it from leaning too heavily in one direction.

For the fertilizer, this kind of plant does not need a lot of nutrients. In fact, too much fertilizer can actually harm the plant. A light feeding of a balanced fertilizer every few weeks is all that is needed. As for the roots, poinsettias are not very demanding. They will do fine in a pot with a good potting mix.

Pruning your poinsettia tree is an important part of keeping it healthy and looking its best. You should prune your tree in early spring, before new growth begins.

Propagation is typically from stem cuttings taken from the previous year's plant in late spring. Cuttings should be 4-6 inches long and taken from the tips of the stems. Cuttings should be taken from healthy, disease-free plants. Allow the cuttings to callous over for a few days before planting. Plant the cuttings in moistened potting mix and keep moist. Rooting will occur in 4-6 weeks. Once the roots are established, transplant to individual pots.
Usually, the plant growth rate is about 6 inches per year. However, this can vary depending on the variety of poinsettia tree and the growing conditions. For example, if the tree is grown in a pot, it may not grow as fast as if it were planted in the ground.
