Poinsettias: Festive Cheer with a Twist
Did you know that the vibrant “flowers” you admire on poinsettias during the holiday season are actually specialized leaves known as bracts? These iconic plants, native to Mexico and part of the Euphorbia family, are synonymous with festive cheer thanks to their bright and varied hues.
While they’re famous for their striking red color, poinsettias also come in shades of creamy white, soft pink, and even patterns that mix these colors. Some garden centers even offer poinsettias in unconventional colors like blue or purple, achieved through spray painting and sometimes a dash of glitter for extra sparkle.
Poinsettias start to show their true colors as the days shorten, responding naturally to the decrease in light by changing the color of their bracts. These not only serve to brighten up our homes but also attract insects to the small, yellow flowers at their center, known as cyathia. After pollination, the bracts will eventually drop off.
Caring for poinsettias is simpler than you might think. They thrive in moist soil within a cozy temperature range of 65 to 70 degrees Fahrenheit and can even be moved outdoors in summer.
Though they’re often rumored to be poisonous, poinsettias are not harmful to pets or humans. However, handling them can sometimes cause skin irritation due to their sticky white sap, so wearing gloves and washing your tools after use is a good precaution.
With poinsettias, you can easily inject a pop of natural beauty into your home. They make stunning decor throughout the year and especially during the winter holidays, proving that beauty can indeed be low-maintenance.

Keep Your Poinsettia Cozy on the Way Home
Don’t let the cold zap the festive spirit out of your Poinsettia! These tropical beauties thrive in warmth, much like us, and chilling temperatures can be detrimental.
Imagine the fate of leaf lettuce caught in a December freeze in central Alberta; your Poinsettia faces a similar risk. You’ll recognize a cold shock by the wilted look they sport, which sadly, won’t perk up with just a splash of water.
To shield your Poinsettia from the winter chill, there are a couple of savvy moves you can make. Timing is everything—grab your plant last during your shopping trips to ensure it spends minimal time in the cold.
When it comes to packing, double layering is your best bet. Start with a paper sleeve, snugly folded at the top, and then slip a sealed plastic bag over it for double protection.
What if the store only offers a basic plastic sleeve? Here’s a tip: bring a large, clear plastic trash bag with you. This way, you can envelop your Poinsettia safely, tie it off gently, and avoid any mistaken glances that might suggest you’re sneaking out more than just good cheer.
Plus, with a clear bag, you can keep an eye on your plant to make sure it’s securely placed in your car, perhaps even buckled up like a precious passenger.
Remember, treating your Poinsettia right from store to home by avoiding icy air and cold car seats will greatly enhance its longevity and beauty. This way, your Poinsettia will continue to brighten your holidays, just as it should!

Light and temperature
To keep your poinsettia thriving through the holiday cheer, it’s all about the right spot and the perfect temperature. Make sure to place your poinsettia close to a south, east, or west-facing window.
This spot should offer plenty of bright, indirect light for about six to eight hours a day—but keep it out of direct sunlight to prevent the leaves from burning. If your plant came in a foil wrapper, peel it back to ensure light reaches every part of your poinsettia.
As for temperature, poinsettias enjoy a cozy range of 65 to 70 degrees Fahrenheit. It’s crucial to avoid areas with sharp temperature swings or drafts from heating vents, fireplaces, or chilly windows, as these can dry out and damage the plant.
Remember, poinsettias are sensitive to the cold and will suffer if temperatures drop below 50 degrees Fahrenheit. Conversely, high temperatures above 85 degrees can also harm them.
When you first bring your poinsettia home, remove any coverings immediately. This prevents the build-up of natural gases that can age the plant prematurely. By managing these conditions, you’ll extend the vibrant life and bloom of your poinsettia, making it a joyful highlight in your festive decorations.

Poinsettia Watering Tips
Keeping Poinsettias healthy is more about restraint than abundance, especially when it comes to watering. Overwatering is a quick way to kill these festive plants, making it the second leading cause of their demise. Interestingly, my kids turned out to be the best at growing Poinsettias simply because they barely watered them at all!
Poinsettias have modest watering needs. Generally, they thrive when watered every week to ten days. However, it’s crucial to monitor them daily since each home’s environment varies.
To check if it’s time to water, I prefer lifting the pot to feel its weight rather than poking my fingers into the soil—I’ve never been fond of getting dirt under my nails.
When the pot feels light, that’s your cue to water, but be cautious not to overdo it. These plants originally come from rainforests where the soil dries quickly. It’s key to keep the soil moist but never soggy.
Overwatering leads to yellowing and dropping of the lower leaves and can cause root rot, which may kill the plant. Conversely, a Poinsettia that’s too dry will also begin to wilt and lose leaves prematurely.
When watering, there are a couple of effective methods:
- Water directly at the soil level to ensure thorough saturation without wetting the leaves, which could lead to issues.
- Alternatively, for a more gentle approach, place the Poinsettia in a shallow dish filled with about two inches of water, removing any decorative pot covers, and allow the plant to soak up water from the bottom for about 15-20 minutes.
Remember how a well-watered Poinsettia feels by its weight—it’s a handy tip to gauge when it might need another drink. Despite their delicate, shallow roots adapted for quick-draining rainforest soils, Poinsettias are prone to root rot if left in damp conditions too long.
Also, once Poinsettias bloom, they don’t require additional fertilizer. They’re at their peak and don’t demand much to keep showing off. It’s vital to check if the soil is truly dry before watering again to avoid the vicious cycle of overwatering, which we often mistake as an under-watered plant wilting for more water.
So, the next time your Poinsettia looks a bit droopy, verify the soil moisture first—it could save your plant’s life!
Fertilizing Poinsettias
Poinsettias really thrive on nutrients when they’re actively growing. Kick off the growing season by fertilizing these vibrant plants as soon as you spot new sprouts—think fresh green leaves or stems. A simple, all-purpose plant fertilizer will do the trick.
Just remember to dilute it to half the strength recommended on the package and water your poinsettia with this mixture every three to four weeks. This regular nourishment helps your plant stay robust and supports sprouting new growth.
Here’s a tip: be careful not to splash fertilizer on the leaves, as this could cause them to burn. And when the festive season rolls around, you can ease off on the fertilizing.
Poinsettias don’t need extra food during the holidays, and continuing to fertilize while they’re blooming with those signature colorful bracts through winter isn’t necessary. So, let them dazzle during the holidays, fertilizer-free!

Caring tips for Your Poinsettia’s New Home
When it’s time to give your poinsettia more room to flourish, late spring or early summer is ideal for moving it into a bigger home. Choose a new pot or a garden spot that’s 2 to 4 inches wider than its current container. If you’re potting, pick a soil blend rich in organic materials like peat moss and ensure the pot has proper drainage to keep things tidy.
For garden planting, select a spot that enjoys partial sun—about 4 to 5 hours a day—and enrich the soil with organic matter like compost to help retain moisture and support healthy root growth. Don’t forget to water your poinsettia thoroughly right after transplanting to settle it into its new environment.
If your poinsettia lives indoors, a late winter trim can do wonders. Cut it back to about 5 inches above the soil to encourage a denser, more attractive shape. Come late May, you might want to trim again, removing 2 to 3 inches from each branch tip to boost branching.
Outdoor poinsettias need a different approach: trim them down to 12 to 18 inches above the ground in early spring and keep pruning monthly until August as needed. Always leave at least four leaves on each shoot or simply pinch the tips of younger, smaller plants to promote fuller growth.
Temperature is key to poinsettia care. Aim to keep your plant in a cozy spot with temperatures ranging from the high teens to mid-20 degrees Celsius. Steer clear of extremes. Avoid placing your poinsettia near heating vents, fireplaces, or any spot that blasts hot or cold air, which can cause the leaves to dry out and crisp up.
Also watch out for chilly drafts near doors or windows that could stress your plant and make it look wilted—a sure sign it’s not happy. Sometimes, they bounce back from the cold; other times, they don’t.
The Secret to Reblooming Poinsettias
Wondering how to get your poinsettia to bloom again? You’re not alone! Many of us love the vibrant holiday colors of poinsettias and want to see them brighten our homes year after year. Although it’s a bit of a challenge, with the right steps, you can transform your poinsettia from its usual green to a festive red, pink, or white—depending on its variety.
To kick off the reblooming process, start by giving your poinsettias 14 hours of complete darkness each night starting at the end of September. During the day, they should be exposed to bright light. Make sure there’s no light seeping in during the dark period—not even from a streetlamp or a reading light.
You might need to cover them with a cardboard box or stash them in a closet. Keep the night temperature around 60 degrees Fahrenheit to encourage the flowering process.
Although it might seem simpler to buy a new poinsettia each year—since commercial growers have mastered the art of producing robust plants with bracts that last months—it’s rewarding to nurture your existing plant.
Once the festive season is over and the bracts fade, reduce watering and keep your plant in a cooler spot, around 50 to 60 degrees Fahrenheit, unless the foliage remains appealing, in which case, continue to enjoy it as a green plant.
In the spring, around March or April, prune the stems back to about four to six inches from the soil surface. If it’s getting crowded in its current pot, it’s a good time to repot it into a larger one with fresh potting mix. If you have multiple plants in one pot, consider giving them their own space by repotting them individually.
When the risk of frost has passed by mid-May, move your poinsettia outside to a partially shaded spot in your garden or along a shrub border. Sink the pot into the ground up to its rim to stabilize it, but ensure the soil drains well to avoid root rot.
Although poinsettias appreciate some outdoor time, make sure they’re not in a spot where hot winds or reflective heat could stress them.
Water the plants as needed, avoiding both underwatering and overwatering. Feed them with a complete houseplant fertilizer throughout the summer, following the instructions for frequency and amount provided by the manufacturer.
In mid-summer, prune the tips of any long shoots to encourage a fuller, bushier plant. If you don’t need new plants, just keep the tips pruned to maintain shape.
By late September, it’s time to bring your poinsettia back indoors to a sunny spot, avoiding too much direct light, which can scorch the leaves. Continue with your regular watering and fertilizing routine, but cut back on the fertilizer as growth slows down.
Give your plant long, uninterrupted nights in complete darkness from 5:00 p.m. to 8:00 a.m. to trigger blooming in time for Christmas.
Enjoy the beauty of your poinsettia each holiday season and relish the sense of accomplishment that comes from nurturing it through the year!

Common Issues with Poinsettias and How to Fix Them
- Root Rot
Noticed your poinsettia’s leaves wilting or turning yellow? It might be dealing with root rot, especially if it’s not growing as robustly as before. This often happens when the soil stays too wet, either due to watering too much or letting the plant sit in waterlogged soil.
To tackle this, try tweaking your watering routine to see if the plant recovers. If there’s no improvement, it could be time to repot. Choose a clean pot that’s just a bit bigger than the current root ball and use fresh, sterile soil to give your poinsettia a fresh start.
- Powdery Mildew
If you spot white patches on your poinsettia’s leaves, powdery mildew could be the culprit. This fungus can block the light, causing the leaves to yellow and fall off. Ensuring your plant gets enough light and air can help prevent this.
If mildew strikes, consider using a fungicide designed to fight powdery mildew. But first, do a spot test on a few leaves to make sure your plant handles the treatment well.
- Whiteflies
Whiteflies are tiny but troublesome pests that love to feed on poinsettias. They suck the sap from the leaves, causing a sticky residue known as honeydew. This can attract more pests and disease. To keep your plants healthy, avoid too much fertilizer, which can encourage lush but vulnerable growth.
Inside your home, yellow sticky traps can help control—but not eliminate—whitefly numbers. Always inspect new plants thoroughly to prevent bringing these pests home in the first place.
