How do you make a poinsettia's leaves turn red?

Answer

In order to get a poinsettia plant to turn red, you need to eliminate its light. Flower formation is actually triggered by periods of darkness. During the day, poinsettia plants require as much bright light as possible in order to absorb enough energy for color production. At night, however, poinsettia plants must not receive any light for at least 12 hours.
