Host Richard Hentschel talks about how to pick and by a fresh poinsettia and the general care to provide longest lasting blooms possible. You should expect 6-8 weeks of a great show. Keeping them evenly water is critical to keeping leaves and colorful bracts on the plant. Water without the foil on to be sure the plant drains out well and them replace the foil. 6 or more hours of indirect light will help them remain healthy longer. Keep them healthy and grow them outdoors for the summer for an entirely different look.
