Poinsettias are a popular gift to give and receive this time of year, and a little tender, loving care will keep them looking good for months to come, according to Kansas State University horticulturist Ward Upham.“Modern poinsettia varieties stay attractive for a long time if given proper care,” said Upham, who is the Master Gardener coordinator with K-State Research and Extension. “Place your poinsettia in a sunny window or the brightest area of the room, but don’t let it touch cold windowpanes.”The daytime temperature should be 65 to 75 degrees Fahrenheit with 60 to 65 degrees F at night. Temperatures above 75 degrees will shorten bloom life, and below 60 may cause root rot.
