Left Over Poinsettia

Question

I received a poinsettia for Xmas last year. I kept it alive until leaves fell off in may. Then i cut it back, and it grew back twice its size. However, the leaves are still green. Will they ever turn red? Thanks

Answer 1

It won't turn red without special treatment. They need 12 hours of complete darkness at night for several weeks. This might mean covering it with a box or paper bag at night. But during the day it needs bright light. If you have a room that isn't used at night you can move it there for several weeks.
