I don't think there's any way around manually adjusting the dark cycle if you want them to bloom for Christmas. If you just want them to colour up, you can chuck them in an empty bedroom with the blinds up and the natural variation in day length should get them to flower eventually.

I kept one for about three years . And soon I'll be building a conservatory to grow plants year round . So maybe next Christmas I'll keep my poinsettia and watch it grow into a large shrub . I've always liked the idea of them being a holiday florist plants that can be kept afterwards . Same goes for Easter Lilly's and shamrock plants

Wouldn't blame ya, I never cut mine back or provided photoperiod . They usually re-flowered (re-bract) in late summer with small sized red bracts . They grow into large sized bushes in Mexico and they are gorgeous . I might put mine in my conservatory as a conservation peice

I wouldn't bother with the darkness Paul it's time consuming . Just give the plant proper care and it will flower on its own time. I alway find it ridiculous in my opinion to severely prune plants back , I also do the same with hybrid tea roses. Let the new growth exist and only prune to keep a bushy uniform shape as desired.

Paul using the bag is useless unless you take it off at the exact same time every day, as little as 15 minutes apart could stop it from flowering. They're obligatory short day plants and will flower as soon as the days are short. The only reason greenhouses use darkness to force them is because greenhouses start selling them at the beginning of November when they're naturally in bloom around Christmas and into January.

The commercial growers start their light regiments usually around the first week of September. They use automatic black-out benches on a computer timer. I have a picture of one of those benches somewhere but I'll need to look for it. They're actually pretty amazing and super handy to do light experiments in!

I have to admit I really don't like points, every class I took used these as examples all the time. I know more then I've ever wanted to know about them haha
