Indoor light: Put in a south, east or west window where the plant will receive bright daylight.
Outdoor light: Part sun, 4 to 6 hours daily.
Indoor temperatures of 65-70 degrees F is ideal.
Avoid placing poinsettias where temperature fluctuates or may be drying, such as near cold drafts, heat ducts, fireplaces, fans, space heaters, etc.
Poinsettias will suffer damage if they are exposed to temperatures below 50 degrees F.
Freezing temperatures will kill poinsettias.
