Make Your Poinsettias Bloom Year After Year
Poinsettias will bloom year after year if you care for them properly. The Michigan State University Cooperative Extension Service published a fantastic, simple chart that details how to make a poinsettia reflower. Simply, in March, remove the flower and cut stems to 6 inches. In June, repot the plant in a larger pot. Then plant it (in the pot) outside. In July, pinch off the lateral shoots. In late August, take the plant inside. From September 20th to December 1st, keep your poinsettia in light from 8 AM to 5 PM only. Keep it in darkness from 5 PM to 8 AM. This will cause the poinsettia to flower by Christmas.
