How to Keep Your Poinsettia Vibrant This Holiday Season—and All Year Long

Most people bring home a Poinsettia before Christmas and discard it shortly after, but did you know you can keep this stunning plant going year-round, even outside in certain climates? Poinsettias are perennials and with proper care, you can help them thrive over the holidays and even make them bloom again the following year.

Keep your poinsettia looking good this holiday season (and beyond)

Did you bring home a beautiful Poinsettia for the holidays? The colorful houseplant has been a Christmas classic since the 19th century. It blooms in winter, making it the perfect centerpiece to brighten your home during the dark and dreary days around the solstice.

While most people ditch their Poinsettias after the holidays, you can (and should) treat yours like any other houseplant and grow it year-round. Here’s what you need to know about caring for Poinsettias in winter, what to do after the holidays, and how to make them rebloom!

It starts with a healthy plant

If you’ve brought home a Poinsettia before, you’ll know that it isn’t the easiest plant to keep alive long-term (which is why some people opt for other types of holiday houseplants). Poinsettias often arrive at your home already stressed from shipping (or from being manhandled at the store), exposed to cold and either underwatered or overwatered.

This means that in many cases, you’re not exactly off to a good start. The species is also prone to leaf drop. To improve the chances of your Poinsettia thriving during (and after) the holidays, look for these telltale signs of a healthy plant:

  • Lush, erect foliage
  • No leaf drop or browning/yellowing leaves
  • Soil is neither dry nor waterlogged
  • Flowers are still closed 
  • Not placed close to the doors in the shop (they don’t like the cold and draft)
  • Planter has drainage holes

Be sure not to expose your plant to extreme cold on your way home, and don’t leave it in the garage overnight.



Quick tip

A Poinsettia’s bracts are often confused for its flowers, but the real flowers are actually tiny and unassuming. You’ll find them in the center of the colored leaves.

Poinsettia care during the holidays

So how do you make sure your beautiful new Poinsettia at least makes it through the holidays?

Packaging: If your Poinsettia was packaged in a plastic plant sleeve, take it off as soon as you get home so your plant is exposed to light and air. Remove the foil wrapping that may be around the pot, as it impedes drainage and can cause your new Poinsettia to drown. (Very important!)

Light: Place your plant in a bright location by a window. You can move it to the Christmas table whenever you want to display it, but the rest of the time, it likes a nice and well-lit spot.

Temperature: Keep Poinsettias away from sources of heat or cold. It won’t like to be by the heater or fireplace, nor close to drafty windows. Poinsettias like it warm (but not hot) during the day and slightly cooler (around 60°F) at night. The warmer your house, the faster your Poinsettia flowers will open up—meaning a shorter bloom time.

Watering: Keep the soil lightly moist using tepid water, never allowing the plant to stand in water for extended periods of time.

For those who want to enjoy their plant a little longer, next let’s dive into how to care for this species year-round and how to get it to rebloom the following year.

Poinsettia care after the holidays

If your Poinsettia is still going strong after the New Year, good job! Many people discard theirs at this point, as it will go dormant and drop (almost) all of its foliage. Not exactly the most decorative thing to look at, I’ll admit that.

Still, there is no reason not to try keeping your Poinsettia alive year-round. These aren’t the easiest houseplants, but I’ve seen some folks have success in reusing theirs for the holiday table year after year. Also, even if yours doesn’t make it, you can just try again next year.

Here’s how you do it:

The rest of winter

After the New Year, begin letting the soil go about halfway dry before watering again. In its natural habitat, things would be heading into dry season now. Poinsettias would go dormant, so you want to achieve something similar in the home.

Poinsettias become naturally leggy as they grow (they’re shrubs that can grow as large as trees in the wild), so I recommend cutting the plant back by at least a third in March or April, when all the colorful bracts and leaves are gone. 

Springtime

Hello Poinsettia! Your plant should begin to come back to life around April or May. You can opt to repot it at this point if necessary, giving it some more space and replacing the low-quality soil they’re often sold in. A general houseplant potting mix is perfectly suitable here.

After repotting, place your Poinsettia in a nice and sunny location, or even outdoors once things have warmed up to 50°F or up. Keep the soil lightly moist, watering when the first few inches have dried out.

Summertime

Your Poinsettia can stay in its sunny spot and will hopefully be growing well at this point. Consider using a diluted liquid houseplant fertilizer every two weeks or so to give it an extra boost.

You can also pinch off some of the stems if you’d like a bushier look on your plant, although doing so is not a must. This practice encourages branching in plants.

Fall: making a Poinsettia rebloom

Bring your Poinsettia back inside (if it was outside all summer) around September. Put it in a sunny window for now. You can continue to water as usual, but it’s time to start tapering off the fertilizer schedule.

If you want to see the plant bloom and color up well for the upcoming holiday season, you’ll have to start giving it some help around October.

The thing is—like many winter-blooming houseplants, including Cyclamen, amaryllis, and the aptly named Christmas (or Thanksgiving) cactus—this species knows it’s time to start producing flowers when the days begin to shorten in fall.

In our homes, however, we keep the lights on until late, which confuses the plant and messes with its blooming period.

To make a Poinsettia rebloom, you’ll want to provide total darkness whenever it’s dark outdoors. At dusk, you can hide it in a closet or place a paper bag over it. When you get up in the morning, put it back in its usual spot.



Quick tip

If you live in a warm climate, you may be able to keep a Poinsettia outdoors year-round and only bring it in for the holidays. This is a convenient option, because you can skip the whole “placing the plant in the closet” process. Nature takes care of that for you as the days shorten in fall—but only if it stays relatively dark in your yard. (Landscape lights or bright street lamps can interfere with blooming.)

Keep this up for about 10 weeks or until your Poinsettia has colored up nicely and produced flower buds. At this point, it’s ready to return to your tabletop full-time.

How long do Poinsettias last?

Poinsettias are tender perennials that can live year-round as a houseplant with proper care, or outdoors as a container plant in USDA hardiness zones 10 to 11 (sometimes it can overwinter in zone 9 with frost protection).

Can Poinsettias live outside in the winter?

Unless you live in zones 10 to 11, probably not. Even there, you’ll have to place yours in a sheltered spot, because they usually struggle when temperatures drop below 50°F. Poinsettias are prone to frost damage in zones 9 and below, and are best overwintered indoors.

Is a Poinsettia toxic to cats and dogs?

Poinsettias are often noted as being highly toxic and even deadly to pets. The good news? It’s a myth!

According to Poison Control, it’s true that consumption can lead to mild symptoms like irritation, diarrhea, and vomiting, but that’s the case with most common houseplants. If your furry friend takes a bite, just keep an eye on it and offer plenty of water.
