Finicky poinsettias flourish with proper care

Modern poinsettia varieties stay attractive for a long time if given proper care. Place your poinsettia in a sunny window or the brightest area of the room, but don’t let it touch cold windowpanes. The day temperature should be 65 to 75 degrees F with 60 to 65 degrees at night. Temperatures above 75 degrees will shorten bloom life, and below 60 degrees may cause root rot. Move plants away from drafty windows at night or draw drapes between them to avoid damage from the cold.

Poinsettias are somewhat finicky in regard to soil moisture. Avoid overwatering because poinsettias do not like “wet feet.” On the other hand, if the plant is allowed to wilt, it will drop leaves. So how do you maintain proper moisture? Examine the potting soil daily by sticking your finger about one inch deep into the soil. If it is dry to this depth, the plant needs water. When it becomes dry to the touch, water the plant with lukewarm water until some water runs out of the drainage hole, then discard the drainage water.
