How to make poinsettas bloom?

I have kept a poinsetta plant for about 2 -- maybe 3 -- years. It is quite healthy, but never blooms. So, how can I make it bloom?

By late March or early April, cut your poinsettia back to about 8 in height. Continue a regular watering program, and fertilize your plant with a good, balanced all-purpose fertilizer. By the end of May, you should see vigorous new growth.

Place your plants outdoors, where they can bask in the warmth of spring and summer, after all chance of frost has passed and night temperatures average 55° F or above. Continue regular watering during the growth period, and fertilize every 2 to 3 weeks.

Good luck.

I found this answer in some info online, I hope it works I am trying it too. God Bless!

Starting October 1, the plants must be kept in complete darkness for 14 continuous hours each night. Accomplish this by moving the plants to a totally dark room, or by covering them overnight with a large box. During October, November and early December, poinsettias require 6 - 8 hours of bright sunlight daily, with night temperatures between 60 - 70° F. Temperatures outside of this range could also delay flowering.

Continue the normal watering and fertilizer program. Carefully following this regime for 8 to 10 weeks should result in a colorful display of blooms for the holiday season!
