I pruned my healthy Poinsettia in September. I have given light and dark conditions but it now looks dead. Should I persevere? Do

Question

you think it will revive? The plant was superb over Christmas and for months after. I followed internet advice and pruned it back to 6 inches at the end of September. Is it still lying dormant.

Answer 1

It shouldn't ever look dead because you are continuing care but giving it 12 to 14 hours of darkness each evening by moving it to a closet or covering it with a box. Each morning it returns to its sunny window. Continue this till about Thanksgiving.
If it truly looks dead, leaves crispy, I think it is a lost cause. Have you been watering and fertilizing?
