If you get sap on you, quickly rinsing it off with water and soap should be enough to prevent irritation. The sap can also damage the plant itself if left on the stems or leaves for too long. If some sap leaks onto the poinsettia plant, wipe it off with a damp rag.

Using clean shears keeps bacteria from getting into the plant, so you may have to disinfect your shears before making any cuts. Never prune more than 30% of the plant. [3] X Expert Source Andi XochPlant Specialist Expert Interview. 4 August 2021.

If you want larger poinsettias during the holiday season, you can leave the stems a bit longer so that they end approximately 8 inches (20 cm) from the rim of the container they are in. The cut stems can be used to propagate new plants. Do this by dipping the stem in a rooting hormone and then planting this into a pot with soil.

Pinched shoots can be used for propagation. Remember to not prune excessively, as the leaves are required for photosynthesis and that’s when the plants get their food and then grow. [6] X Expert Source Andi XochPlant Specialist Expert Interview. 4 August 2021.

If you bought your plant in winter, it is likely to be in a pot wrapped in foil. Take the pot out of the foil in order to allow for drainage.

Setting a daily alarm is the best way to remind yourself when to do this and keep you on track for beautiful plants during the holiday season. During the other hours of the day, the plant should receive normal lighting conditions.
