Poinsettia Care: How to Keep It Red Through the Holidays

Few plants say “Christmas” like a poinsettia. Its bright red leaves bring instant colour to a living room, an office reception or a holiday table. But many people find their poinsettia dropping leaves or fading before the holidays are even over. The good news is that poinsettias are not difficult. They simply have a few specific needs, and once you know them, your plant can stay vibrant well into the new year.

This guide covers everything you need to know, from choosing a healthy plant to watering, light, temperature and what to do after the holidays.

A Quick Introduction to Poinsettias

Poinsettias are native to Mexico, where they grow as tall shrubs in warm climates. The colourful “petals” are not actually petals at all. They are modified leaves called bracts. The true flowers are the tiny yellow buds in the centre, called cyathia. Understanding this helps with care: when the yellow buds drop, the plant is reaching the end of its colourful display.

Because they come from a warm climate, poinsettias dislike cold, drafts and sudden temperature changes. Most care problems come down to one of these.

How to Choose a Healthy Poinsettia

A good poinsettia starts with a healthy plant. Look for:

• Tight yellow buds in the centre. If the tiny yellow flowers are fresh and closed, the plant will last longer. If they have dropped, the plant is older.
• Full, colourful bracts with no brown edges or pale patches.
• Dark green leaves all the way down the stems, not yellowing or falling.
• Moist but not soggy soil. Wilting with wet soil can be a sign of root problems.
• A balanced shape that looks full from every side.

When you order from a florist, plants are checked before they leave the studio, so you receive a healthy poinsettia ready to display.

Getting Your Poinsettia Home Safely

Poinsettias are sensitive to cold. Even a few minutes below about 10°C can damage the leaves. In a Vancouver December, with rain, wind and occasional frost, this matters.

• Keep the plant wrapped in a sleeve or bag when carrying it outdoors.
• Do not leave it in a cold car while running other errands.
• Unwrap it as soon as you are inside, and remove any plastic sleeve within a few hours.

With delivery, our drivers keep plants protected from the cold and bring them straight to the door, concierge desk or reception.

Where to Place Your Poinsettia

Light

Poinsettias love bright, indirect light. A spot near a window that gets plenty of daylight, without hot afternoon sun hitting the leaves, is ideal. In Vancouver’s short winter days, a bright room makes a real difference.

Temperature

Aim for a room between 16°C and 22°C during the day, and not below about 13°C at night. This is a normal home or office temperature, which is why poinsettias suit indoor life.

What to avoid

• Cold drafts from front doors, balcony doors and windows that open often.
• Heat sources such as fireplaces, radiators, heating vents and electronics.
• Touching cold glass. Leaves that rest against a cold window can be damaged overnight.
• Office lobbies with automatic doors, which let in a burst of cold air every few minutes.

How to Water a Poinsettia

Watering is where most poinsettias go wrong, usually from too much water rather than too little.

• Check the soil every few days. Water when the top 2 to 3 cm feels dry to the touch.
• Water thoroughly until it drains from the bottom of the pot.
• Never let it sit in water. Decorative foil and pot covers trap water. Remove the plant from the cover to water it, let it drain in the sink, then return it.
• Use room-temperature water. Very cold water can shock the roots.

In warm, dry condos with the heating on, you may need to water every three to five days. In cooler rooms, once a week may be enough.

Humidity and Feeding

Indoor air in winter is dry, especially in heated condos and office towers. Poinsettias appreciate a little extra humidity. Grouping plants together or placing the pot on a tray of pebbles with water below the pot base can help. There is no need to fertilize while the plant is in colour over the holidays.

Why Is My Poinsettia Dropping Leaves?

Leaf drop is the most common poinsettia problem. The usual causes are:

• Cold exposure, during transport or from a draft. Leaves may drop suddenly a day or two later.
• Overwatering, especially if the pot sits in a foil wrap full of water. Lower leaves turn yellow and fall.
• Underwatering, where the plant wilts dramatically. A thorough watering usually revives it within hours.
• Too little light, which causes gradual yellowing and leaf loss over a few weeks.
• Sudden temperature changes, such as moving from a warm room to a cold hallway.

Once you correct the cause, the plant usually stabilizes. Remove fallen leaves so the plant stays tidy.

Poinsettia Colours and Varieties

Red is the classic choice, but modern poinsettias come in many beautiful shades:

• Classic red for traditional holiday decor.
• White and cream for minimalist, modern interiors and elegant offices.
• Soft pink and salmon for a softer, contemporary look.
• Marbled and speckled varieties with two-tone bracts for something unexpected.

White poinsettias are especially popular for condos and offices with neutral colour palettes, while red suits traditional holiday tables. You can find poinsettias and other seasonal plants in our Christmas and New Year collection.

Displaying Poinsettias in Condos and Offices

A poinsettia can do more than sit on a side table. A few styling ideas for Downtown Vancouver homes and workplaces:

• Kitchen islands and dining tables: a single white or red poinsettia in a simple ceramic pot makes an easy centrepiece.
• Reception desks: two matching plants on either side of the desk create a welcoming, symmetrical look. Keep them away from the entrance doors.
• Boardrooms: a row of compact poinsettias along a credenza adds colour without blocking sightlines.
• Window ledges: bright and festive, but make sure leaves do not touch the cold glass.
• Mixed displays: combine poinsettias with evergreen branches, pine cones and candles in hurricane glass for a full holiday look.

Swap the plastic grower’s pot cover for a decorative pot that matches your interior, and remember to remove it when watering.

Are Poinsettias Safe for Pets?

Poinsettias have a reputation for being highly poisonous, but this is largely a myth. According to veterinary sources, the milky sap can cause mild irritation to the mouth and stomach if a pet chews the leaves, but serious poisoning is rare. Still, it is best to keep the plant out of reach of curious cats and dogs, and of young children. If you are worried, contact your veterinarian.

Poinsettias as Holiday Gifts

Poinsettias make wonderful gifts for hosts, neighbours, building staff, colleagues and clients. They are affordable, festive and last much longer than a box of chocolates. For offices, a group of matching poinsettias at reception or along a window creates a beautiful seasonal display.

Poinsettias are also among the first holiday plants to sell out each December. Read our guide on when to order Christmas flowers in Vancouver to plan ahead.

What to Do After the Holidays

With good care, your poinsettia can stay colourful through January and often into February. After that, you have two options.

Enjoy it as a green plant

Once the bracts fade, a poinsettia is still an attractive leafy plant. Keep it in bright light, water when the soil is dry, and feed it lightly in spring and summer.

Encourage it to colour again next year

Getting a poinsettia to turn red again takes patience. In spring, cut the stems back to about 15 cm. Grow it in bright light through summer. Then, from early October, the plant needs about 14 hours of complete darkness every night for eight to ten weeks. A closet or a box over the plant works. Any light during the dark period can stop the colour from developing. If all goes well, the bracts start to colour by December.

Caring for Other Holiday Flowers

If you also have fresh holiday arrangements at home, they need a different care routine from potted plants. Our guide on how long fresh flowers last explains how to keep cut flowers fresh through the season.

Frequently Asked Questions

How often should I water a poinsettia?

Water when the top 2 to 3 cm of soil feels dry, usually every three to seven days depending on how warm the room is. Always let excess water drain away.

Why are the leaves on my poinsettia falling off?

The most common causes are cold drafts, overwatering, underwatering, too little light or sudden temperature changes. Move the plant to a bright, stable spot and check the watering.

How long do poinsettias last?

With good care, poinsettias keep their colour for six to eight weeks or more, often well into January and February.

Where is the best place to put a poinsettia?

In bright, indirect light, away from cold drafts, heaters and fireplaces, in a room between 16°C and 22°C.

Are poinsettias poisonous to cats and dogs?

Poinsettias are only mildly toxic. The sap can irritate the mouth and stomach, but serious poisoning is rare. Keep them out of reach of pets to be safe.

Can I make my poinsettia turn red again?

Yes. From early October, give it about 14 hours of complete darkness each night for eight to ten weeks, with bright light during the day.
