How do you get Poinsettias to bloom?
To flower and develop colored bracts, a poinsettia must receive as much sunshine as possible during the day. Starting about October 1, it also needs at least 14 hours of uninterrupted darkness each night at temperatures between 60 and 70 degrees. Stray light of any kind (street lights, pool lights or lamps) could delay or entirely halt the reflowering process. (See Figure 2). The dark treatment should last until color shows in the bracts (approximately Thanksgiving). Some modern cultivars may show color as much as two weeks before Thanksgiving. Continue fertilizating and watering to encourage good growth. I put mine in the closet.
