Did you buy a beautiful poinsettia plant, but now it's wilting? Poinsettias are plants and they need the same care as any sick houseplant. If you provide water, warmth and light, your poinsettia should recover and bloom through Christmas and beyond.
Check to see if your poinsettia's container has drainage holes. The water needs to be able to drain from the container because if the poinsettia sits in excess water, it will suffocate the roots.
