Getting Poinsettia to Rebloom
I tried to force my poinsettia to rebloom this year. I have been giving it dark treatments each night. Some of the leaves are speckled with red but no flowers. Will it ever bloom?
The colorful parts of the poinsettia are the bracts not the true flowers. These are leaves that turn color during the flowering process. The poinsettia flower is really a knobby yellow growth that appears in the center of the bracts at the tip of stem. Keep providing your poinsettia with 14 hours of total darkness each night until the bracts are fully colored. Each missed or interrupted dark period delays bloom by one day. You may have missed a colorful Christmas display but the sense of accomplishment you'll feel and the fully colored beautiful bracts can brighten any dreary winter day.
