Answer: Poinsettias thrive in sunny indoor sites, in average household temperatures. They are sensitive to drafts or sudden temperature changes, and prefer moist (but not soggy wet) soils. If any of these conditions are not met, the plant will react by wilting, dropping leaves, and dying. Make sure you are not overwatering. (Wilting can be a sign of overwatering as well as underwatering.) For large containers, wait until the soil is dry down an inch or so before watering. Try placing it in a sunny window; it may regain its health.
