Few people get through the Christmas season without receiving a poinsettia plant as a gift. Often wrapped in shiny foil paper or a decorative pot, the poinsettia (Euphorbia pulcherrima) is the unofficial plant mascot of Christmas. If you want to enjoy your poinsettia beyond the holiday season, keep it alive with the right care. A poinsettia can even be coaxed to survive through the following Christmas and re-bloom for the next holiday.
Place the poinsettia plant in bright, indirect sunlight for at least six hours each day.
Maintain air temperatures around the poinsettia plant of 68 to 70 degrees F. Keep the poinsettia away from cold drafts, heating or air conditioning vents, or other places with temperature extremes or fluctuations.
Water the poinsettia when the top 1 inch of soil feels dry to the touch. Water the plant to moisten the soil moderately and evenly.
Keep the air humid around the poinsettia plant by placing the pot on top of a drainage dish filled with water and gravel. Ensure that the pot is sitting on top of the gravel and not in the water.
Feed the poinsettia plant after it's finished blooming with a balanced, all-purpose houseplant fertilizer once each month during its non-blooming seasons. Follow the dosage instructions on the fertilizer label.
