Q&A for How to Revive a Dying Poinsettia

Your poinsettia could be dormant or it could have dropped its leaves for reasons such as over watering or being housed near a draft. Continue watering your plant and keep it in a bright room to see if leaves will grow back. After a few months if there is no sign of growth your plant is likely dead.

Yes! It does fine in a heated greenhouse. Don't let it get below 42° & have a sunscreen cover to filter direct sun.

Trim the broken ones back to an 1/8 inch above a good bud or branch, then water it once or twice a week.

Yes they will.

It depends if it over dried and the plant actually died. If there is some life in it however, watering it will help revive it.

Water it a little more every day, and plant a few extra seeds in with the flowers so it will receive nutrients.

No.

Make sure the plant is getting 3/4 a cup (180 mL) of water every day and keep it in an environment that's between 65°F and 75°F (18–24 °C). If it's fall or winter, you can also try feeding it a small amount of water-soluble organic fertilizer every 3-4 weeks to return it to health.

This could be alternaria leaf spot, in which case you should take measures to prevent it from spreading. Prune it, then spray it with fungicidal spray.

You have to replant it quickly! Any later than a day and it will die. Keep it in a cool place and give it plenty of water.

Drooping can actually be a sign of overwatering. Stick a finger in the soil to make sure that it's moist, but not overly saturated. Also keep in mind that some drooping may be normal while the plant recovers and prepares to flower once again.

It's possible, but not likely. Poinsettias don't take well to cold environments. Bring your plant inside as soon as you can and keep it at a constant temperature of 65–75 °F (18–24 °C). Situate it someplace where it won't get caught in a draft or cold spot (like beside your front door or in front of a poorly insulated window).

Yes. To make fresh flowers last longer, try waving a lighter flame over the cut or broken end of the stem. This seals the tiny pores in the stem, preventing the flower from losing anymore moisture.

With regular watering, pruning, and indirect sunlight, probably. Be careful not to overwater the plant, however, as this can actually do more harm than good. If the leaves look rubbery or wilted, there's a chance the plant is taking in an excessive amount of moisture.

Not necessarily. A poinsettia that's flowering for the second or third time may not ever regain it's original coloration. Covering the foliage and keeping the plant in total darkness during fall and early winter will help improve its chances, though.

It is too late to use this as a remedy when all the leaves and stems have rot. If, however, you have seeds, then plant them immediately after you have removed the unwanted roots and leaves.

Maybe you have not been watering the amount needed. Be sure to water them to about 3/4 of a cup every day and keep them in sunny spot in your house.

The plant's leaves will provide the color changes through a process called photoperiodism. This process, in response to certain amounts of light or lack thereof, will turn the leaves from green to red (or pink, white, and other shade variations).
