Question
My Poinsettia bush outside my house just started to turn red in late January, how do I get it to turn red before Christmas?  

Answer
Forcing Poinsettias

Forcing Poinsettias to bloom is a difficult task. Many have tried, but few succeed. But, if you have kept them around and healthy all year, you've just gotta give it a try.

The concept is simple enough. Any time from late September to October first, you need to put the plant in total darkness for 12-14 hours a day. Here is where it's tricky. Any small light can upset the process. During the day, it should get six hours or more of sunlight. Continue this process daily until early November, then bring it out into the room. Now with a little luck (some will say a lot of luck) and your personal green thumb, it will be in full bloom during the Christmas holiday.

Tip: A black plastic bag works well. Place the plant in the bag and use a twist tie. Each morning, remove the twist tie and carefully lower the bag to the floor.

BEST OF LUCK!
