Tips for Making Poinsettias Last All Season
Poinsettias are renowned as iconic holiday plants, instantly recognizable thanks to their vivid red, white, or pink bracts. These festive favorites can brighten any room from Thanksgiving through New Year's Day and beyond--but only with proper care! Want to keep your poinsettias thriving and beautiful well past the holidays? Read on for our comprehensive guide full of expert tips for making poinsettias last all season.
Introduction: The Beauty and Challenge of Poinsettias
Poinsettias (Euphorbia pulcherrima) are native to Mexico and Central America. In their native habitat, these plants grow as woody shrubs, but indoors they are treated as seasonal houseplants. Poinsettias are often seen as disposable decorations--however, with the right care, you can easily extend your poinsettia's life and enjoy their colorful bracts for months.
Below, we'll uncover the best ways to care for poinsettias, help them last all winter, and possibly coax them into blooming again next year.
Understanding Your Poinsettia
What Are the Colorful "Flowers"?
The brightly colored leaves on poinsettias are not actually flowers, but bracts--a type of modified leaf. The true flowers are the small yellow cyathia at the center. When selecting a plant, choose one with lots of yellow buds for the longest possible display, as these indicate freshness.
Basic Poinsettia Needs
- Light: Poinsettias need bright, indirect sunlight for best color and vigor.
- Temperature: Keep temperatures between 65-75?F (18-24?C) during the day, and avoid exposing the plant to temperatures below 50?F (10?C).
- Humidity: Winter homes are often dry; aim for moderate humidity to prevent leaf drop.
- Water: Overwatering is a common killer--let the top inch of soil dry before watering.
How to Choose a Healthy Poinsettia
The longevity of your holiday poinsettia starts at the store. Here's what to look for:
- Deep green foliage all the way to the base of the plant
- No yellow, wilted, or brown leaves
- Plentiful yellow cyathia, not yet dropped
- Firm stems, not mushy or broken
- No signs of pests or mold on leaves or soil
Tip: Wrap the poinsettia for the trip home in cold weather since they are extremely sensitive to low temperatures and drafts!
Poinsettia Placement: Where to Keep Your Plant
Find the Perfect Spot
Position your poinsettia in a room where it receives ample bright, indirect sunlight for at least 6 hours a day. Avoid direct south-facing windows where midday sun is harsh, as this may fade bract color and dry the plant out.
Avoid Drafts and Heat Sources
- Keep away from cold windowsills, exterior doors, fireplaces, and heat vents
- Avoid sudden temperature changes, which can trigger leaf and bract drop
Pro tip: Poinsettias are happiest in stable, room-temperature environments, away from temperature extremes and drafty areas.
Watering Your Poinsettia: What You Need to Know
How Often to Water
The main cause of poinsettia decline is improper watering. Follow these watering guidelines:
- Check soil daily. Water only when the top inch or two of soil feels dry to the touch.
- Water thoroughly until excess drains out the bottom--but never allow the plant to sit in standing water. Remove foil wrappers or poke holes in decorative pots for drainage if needed.
- If your poinsettia is wrapped in plastic or in a saucer without drainage, remove the pot and water over the sink, letting it drain fully before replacing it.
- Reduce watering as winter progresses and growth slows.
Humidity and Air Quality for Healthy, Long-Lasting Poinsettias
Homes in colder climates tend to have very dry indoor air. Since poinsettias need moderate humidity, dry air can cause leaves to curl and drop prematurely. Here's how to offset that:
- Group plants together to increase local humidity
- Set the poinsettia on a humidity tray (a shallow dish with pebbles and water, pot above the waterline)
- Consider running a room humidifier during the winter
Avoid misting: Misting can encourage fungal diseases on leaves and bracts, so it's best to use other methods to boost humidity.
Fertilizing Your Poinsettia
During the holiday display period, your poinsettia doesn't require extra fertilizer. Wait until late winter or early spring if you intend to keep the plant year-round.
- Once new growth begins, feed monthly with a balanced, all-purpose houseplant fertilizer, diluted to half-strength.
- Avoid fertilizing when the plant is dormant or colors are fading after the holiday period.
Pruning and Pinching: Keeping Your Poinsettia Compact
If you wish to keep your poinsettia as a houseplant after the holidays, it benefits from pruning:
- In March or April, cut back the plant to 4-6 inches tall to encourage bushier regrowth.
- Pinch back growing tips in early summer to foster a compact, full plant shape.
Common Poinsettia Problems and How to Avoid Them
Leaf Drop
Sudden loss of leaves or bracts usually signals:
- Exposure to drafts or cold temperatures (most common)
- Over- or under-watering
- Lack of sunlight
Wilting
- Check soil moisture. Overly dry or soggy soil can both cause wilting and root rot.
Pests
While rare indoors, watch for whiteflies, fungus gnats, and spider mites. Wipe leaves with a damp cloth and treat with insecticidal soap if necessary.
How to Make Poinsettias Bloom Again Next Year
Want to turn your holiday poinsettia into a year-round houseplant that reblooms every winter? It's possible, but requires a bit of patience and a specific light regimen. Here's the step-by-step:
Post-Holiday Care
- After the bracts fade, prune the plant back to about 6 inches tall.
- Continue normal watering, keeping the soil just damp.
- Move outdoors to a partly shaded spot after danger of frost (if you live in a warm climate) or keep by a sunny window indoors.
- Fertilize lightly during the growing season (spring and summer).
Preparing for Rebloom - The Critical "Dark Treatment"
To get poinsettias to color up for the holidays, you must simulate the short-day/light cycle:
- Starting around late September or early October, place your plant in total darkness for 14 hours each night. Use a box, bag, or closet (no cracks of light!) from 5pm to 7am.
- During the day, return the plant to a bright window for at least 6 hours.
- Continue this regimen for about 8-10 weeks, until bracts begin to show color.
- Once coloring starts, the dark treatment can stop and normal indirect light can be resumed.
This short-day treatment triggers the development of colorful bracts--just in time for the next holiday season!
Frequently Asked Questions About Extending Your Poinsettia's Display
Are poinsettias poisonous to pets?
Poinsettia sap can cause mild mouth or stomach irritation in pets, but it is not highly toxic. Still, keep plants out of reach of curious cats and dogs.
Can I plant my poinsettia outside after the holidays?
Poinsettias are frost sensitive but can be grown outdoors as landscape plants only in USDA zones 9-11. Elsewhere, keep them indoors as houseplants or compost after the season.
Why are my poinsettia's leaves turning yellow?
Yellow leaves are usually caused by overwatering or root rot. Allow the soil to dry slightly before watering again and improve drainage if needed.
Quick Recap: Top 10 Tips for Keeping Poinsettias Fresh All Season
- Buy a healthy plant with no yellow leaves and plenty of buds
- Protect from cold when transporting home
- Place in bright, indirect light
- Keep away from drafts and heating vents
- Water only when soil is dry to the touch, ensuring good drainage
- Maintain moderate humidity
- Avoid misting to discourage disease
- Don't fertilize during the flowering (holiday) period
- Prune back after bracts fade if keeping year-round
- Follow darkness regimen in fall for reblooming
