My brother bought me a beautiful Poinsettia plant last year and by some miracle I've managed to keep it alive, in fact it's looking very well. I've read that to encourage it to flower and produce colourful bracts I need to ensure it gets 14 hours of darkness followed by 10 hours of daylight for the next two months. Now this just isn't possible because on the days I work I'm out of the house from about 07.00 to 18.00 (at least) and there's no-one else to help. So probably the best I can do is 12 hours of darkness. Will this suffice?
