7 Tips for Poinsettia Plant Care, through the Holiday Season and Beyond
Keep those poinsettia plants going strong, especially after the holidays! Poinsettias can even be kept year after year to rebloom if you give them proper care. See our tips on top mistakes to avoid.
Poinsettias (Euphorbia pulcherrima) are the perfect Christmas plants that bloom when the days are shorter! By the way, the showy red parts of Poinsettia plants are not flowers; rather, they are modified leaves known as bracts. A poinsettia plant’s actual “flower” is the yellow bloom at the center of the bracts.

Poinsettia Care: 7 Tips to Follow
At home, follow these plant care tips:
- Poinsettias are particular about light. They require bright light during the day for the brightest color (at least 6 hours a day), but they don’t like direct light that could fade or burn the leaves. In the winter, place yours near a well-lit window. East-facing windows are best.
- Avoid spots near heating vents and doors, as well as hot appliances. Cold drafts will cause leaves to drop. No part of the plant should touch the cold glass. Excess heat can dry out the plants too much.
- Poinsettias favor semi-cool conditions. Keep temperatures between 65° and 70°F, ideally. Basically, maintain temperatures that are comfortable for people. Be sure to lower the thermostat at night so that plants cool off.
- Do NOT overwater. Keep the soil moist, but be careful not to overwater, which is the most common cause of death. Only water when the top inch or two of soil feels dry to the touch. If underwatered, plants wilt and shed leaves.
- Don’t let the plant sit in water or water-filled sauces, which causes root rot. Be careful to remove any foil which may gather water. Treat the saucers like water catchers, and 30 minutes or so after a good watering, detach it in the sink and let it all drain out.
- Fertilizer is never recommended while the plant is in bloom. Fertilize only if you decide to keep them after their holiday bloom.
- Poinsettias like humidity. Add plants nearby to aid humidity. Use a humidifier or place plants on a tray filled with pebbles and water to increase relative humidity.
Keeping Poinsettias Year After Year
Poinsettias are not frost-tolerant. As holiday plants, they are raised in greenhouses in cool temperatures (60° to 72°F) with high humidity and light intensity, so it can be tricky to duplicate the ideal environment for poinsettias. If you wish to attempt to keep your poinsettia going, here are seven steps:
- When the bracts fall off or yellow, gradually withhold water so the soil’s no longer moist. But don’t let the soil go 100% dry. Water just enough to keep the stems from withering.
- Then move the poinsettia to a cool, dark area (50 to 60°F), dry, dark area until spring.
- In April or May, put the plant back in a sunny location. Cut the branches down to just 6 inches about the soil level.
- At this point, many folks will repot the plant in fresh potting soil that has good drainage to avoid root rot. Water the new soil well, allowing it to drain away.
- Once the plant is growing actively, fertilize once a month with one tablespoon of soluble fertilizer, such as 20-20-20, per gallon of water)
- Keep the poinsettia plant actively growing all summer by watering and fertilizing regularly. When the top of the soil feels dry, liberally apply water to moisten the soil completely and allow the excess to drain away. Add no more water until the top of the soil is dry again.
- After the plant’s stems have grown about 10 inches, pinch off the tips of new shoots, keeping the strongest branches. This encourages a bushy plant. Continue to pinch once a month.

My wife has 2 poinsettias that she has had for 2 and 3 years. She cuts it back to about 6" when "Christmas" extended is over and plants it outside when it is warm enough in northern Kentucky. They grow from that 6" up to about 24-30" and about 2-3' in diameter during the summer and early fall. When frost threatens, she brings them in, puts them in our enclosed sunporch and lets the red happen even further. One is going out this year, as the pot, which has to be increased as the plant gets older, is getting too big. But we got 4 in one pot this year, 2 red and 2 white, so I think she will keep one of each and we'll have red and white this coming Christmas.
I also love in nky and was able to keep my christmas poinsettia alive this year! Where outside do you have it? I repotted it but it looks insure.
I have 4 in a pot I had them outside on my covered patio all summer.when it started getting in the 40s here in Raleigh NC I brought it in.put it in dark room at night an light daytime.it is not blooming at all.what am I doing wrong
I looked into this a few years ago, to trace the origin of the myth. Apparently the myth stems entirely from one case of a child dying of unknown causes in 1911, who had been known to eat poinsettia leaves. There was no other reason, evidential or even documented, to label the plant poisonous for the next 100 years, and I find, when confronted by one of the thousands of Americans still sharing this belief, the best response is to simply pluck a leaf and eat it in front of them.
Oh, that's a hoot.
I have several poinsettia plants that I have had over the last 3 years or so. They are all in different pots. Can you put more than 1 plant in a bigger pot together ? Or is it better to leave alone in a pot?
Hi, I have a poinsettia from Christmas 17' I am not interested in forcing it to bloom. I just want to keep it happy. It was the only living thing in the hospital room with a dear friend when he passed and the priest who gave him his last rites brought it from the church on Christmas Eve. So it is my mission to keep it alive and happy. I almost killed it when I moved it to a different location and forgot water it. Right now it looks like more of tree. Should I be pruning it? I can send pictures if you have an email address or FB page. Thank you.
Whatever you’ve been doing, keep it up, Eileen! Your success is remarkable. The “A” months are the time to prune poinsettia–April and August (yes, both, according to experts at a nursery in Hawaii, where these plants grow like bushes). In April, they say, remove all foliage and cut back to 4 to 6 feet in height. You could also repot it at this time. Begin to fertilize it in early May, when it sprouts new growth. Pinch back new growth in late May/early June so you encourage branching. In August, trim all shoots to 3 to 4 leaves to prepare the plant to bloom.
Did your aunt cover her outside plant to keep it blooming each year? How did she care for it?
Thank you
