Poinsettias (Euphorbia pulcherrima), also known as Christmas star, are ethnic to Mexico. They grow every bit shrubs, reaching heights of 12-anxiety tall, with the familiar reddish and greenish foliage and tiny yellowish bud-like flowers.

The stems start to become gangling and tall, simply like their ancestors were, and some pruning is needed to go on them looking compact and full.

With over 100 cultivated varieties, poinsettias come in all sorts of colors including the traditional carmine, apricot, salmon pinkish, orangish, yellow, cream, and white. There are also plenty of multi-hued, marbled, and speckled variations.

Y'all may as well notice unusual blue, purple, and sparkly silverish ones in shops: those are dyed and glittered, and, well, perhaps not really suitable for those of the states who like some nature in our plants.

The true flower of a poinsettia is actually only the tightly-clustered yellow buds in the heart (termed 'cyathia'). The surrounding leaves that change color are modified leaves called bracts. The rest of the institute has dense, green leaves.

Poinsettias every bit Houseplants

What makes poinsettias different than another tropical houseplants is their intolerance for temperature swings, drafty conditions, and soggy soil.

They exercise best with even atmospheric condition (60-70°F | 15-21°C) with diffused sunlight half-dozen hours a twenty-four hours, and the potting soil on the drier side, only never dried out.

If temperatures get below 50°F (ten°C), information technology tin can be game over.

How to Choose a Healthy Plants

When buying a poinsettia, these tips will help you choose the healthiest plant with the best chance of a long life.

The plant should take an overall salubrious and robust appearance: no dying, yellowing, or fading leaves or other signs of distress.
The flowers (yellowish buds in heart of leaves) should be tight, not open or spilling pollen.
Check the temperature of the container with your easily. Information technology should be room temperature and not cold. Some poinsettias are (wrongfully) kept refrigerated prior to brandish in stores.
Avoid plant displays by the front of the store where automatic doors are letting bursts of cold air in. The plant may look okay today, but a calendar week from at present it may dice off.
Put your fingertip in the potting soil to cheque the moisture level. You don't want soggy soil, nor should it be then dry out that the soil is shrinking back from the inner sides of the pot.
Check nether leaves for insects, eggs, or signs of munching. Allow no buggy plants come home with you!

When you've picked the best institute, it must be completely covered for the ride home to avoid exposure to wind and cold temperatures.

In that location's a honeymoon period of most half dozen to eight weeks where your poinsettia volition look fabled and require minimal care.

Follow the watering tips beneath and continue away from cold drafts.

When you buy your plant, remove the decorative foil wrapper or brand holes in it to permit backlog water to freely drain out of the pot into a saucer.
In a heated home with moderate humidity, watering may be need around 1x a calendar week or a chip sooner.
Finger test! H2o when the potting mix is dry out to touch (one knuckle deep). Or use a wet meter.
H2o enough to reach the roots. Empty any backlog h2o in saucer.
Never let the soil to dry out, just never let it stay soggy either.

Grow Indoors Year-Round

I'll walk yous through a year of poinsettia intendance. The first half of the year is basic care. Then we have steps to encourage the plant to go into color once again ("bloom") for the next holiday flavor.

These milestones may not happen right on schedule, just yous'll get the idea of what to look.

Jan to March

As your poinsettia starts to look a little tired, nosotros begin its showtime year as a houseplant.
Provide half-dozen hours a day of diffused dominicus and water lightly when the soil is dry to bear upon.
Don't freak out if leaves drop or shrivel. It may be just recovering from the intense conditions that made it so pretty for the holidays.
The adjacent few months are a rest period.

April

When new growth appears, you tin begin fertilizing. I use liquid fish fertilizer (post-obit the directions on the container) but you can utilize any general fertilizer made for indoor plants and follow the instructions on the product label.
If there are dead flowers or bracts, you lot can pinch those off.

May

Information technology may be time to repot the institute to a container i size up. Use a sterile potting mix made for indoor flowering plants.
Some time between May and July, your poinsettia should be ready for pruning.
Using clean tools, cut back stems to approximately 4-inches tall—some gardeners become downwards to as little as two-inches—cut merely above leaf nodes (those bumpy parts on the stems where stems and leaves grow from).

TIP: If you want to try propagating your poinsettia, now is the time. This tutorial shows how to accept softwood cuttings and root them. It's the aforementioned process for poinsettias.

June to August

When outdoor temperatures are consistently over 55°F (12°C), you can grow your poinsettia outdoors for the summer months (or just keep information technology indoors).
Place your poinsettia in indirect light to avoid sunburn and never let it dry out.
Continue watering as earlier, waiting until potting soil is dry to touch, and never soaking or starving the plant.
I like to utilize half-strength fertilizer in the water all the fourth dimension, rather than remembering to requite full-strength periodically.
The plant should start to regenerate during this phase, sending upwards new shoots and leaves.
If information technology gets leggy, prune as needed, and article of clothing gloves to avert contact with the sap which can be irritating.

September

Here in Ontario, Canada, some time effectually late August or early on September, I start bringing my houseplants back in for the winter—one form of 'overwintering'—just as nighttime temperatures start to fluctuate.

Overwinter Poinsettias Indoors

Remove whatever dead thing.
Wash leaves gently with warm water.
Use an organic insecticide to remove any critters (if you feel it is necessary).
Render to a draft-complimentary, sunny window indoors.

The ideal indoor temperature range is 60°F (15°C) to 70°F (21°C).
Subsequently a month or so indoors, it's time to forcefulness your baby to become colorful once again.

How to Make Poinsettias ReBloom

Oct and Nov

This is the function that takes some dedication to see it through.

I gear up daily reminders on my phone because you lot have two unproblematic tasks to practise every twenty-four hour period, as you lot'll see.

For this adjacent stage, we're going to alternating betwixt periods of light and full darkness every single solar day for half-dozen to 8 weeks.

Daytime: keep your poinsettia in the sunniest location you have.
Nighttime: provide consummate uninterrupted darkness for 12 to 15 hours a day (whatsoever fits your schedule).

The easiest way to do this is to find a paper-thin box large enough to set over the found with the flaps splayed on the floor and so zero light gets in.

You might do this right past the window or choose to movement the found each evening to a box in another room and render it to the sun in the forenoon.

Continue watering and fertilizing as usual during this time.

Colour Change

Some time during this phase, yous may notice buds (cyathia) forming or yellowing, and their surrounding leaves (bracts) gradually changing colour.

Some people notice this as early as 2 weeks in.

Keep going until your poinsettia has transformed.

Not to be a Debbie Downer, simply, as mentioned, some poinsettias won't produce their original colors again, and others volition change but slightly, but goose egg compared to their original show.

You can make up one's mind if it'southward still a worthwhile houseplant or if you would rather transport it to the Pearly Gates in the compost pile.

Best case scenario, over the 6 to 8-week period, the buds plow yellow and the bracts plow red, pink, white—or whatever they shall exist, and y'all go to enjoy the blooming phase all once again.

Pests and Diseases

Poinsettias are susceptible to fungal, bacterial, and parasitic diseases.
Overwatering can kill a poinsettia or cause grey mold to class.
A weakness in the plant or life outdoors can also attract mealybugs, whiteflies, and scale insect.
If a pest problem arises indoors, if serious, I usually dispose of a plant rather than trying to treat information technology to avoid affecting my other plants. Life is just besides short sometimes to fuss with these things.

Ofttimes Asked Questions

Are poinsettias poisonous?

Poinsettias are not poisonous the way we have been led to believe. As office of the spurge family (Euphorbiaceae) including condom copse that produce latex, poinsettias produce a milky sap which some people (like me) are either sensitive or allergic to. If handling the plant, utilise gloves to prevent peel or eye irritation.

As for the rumors of beingness wickedly poisonous, it's not so. Studies evidence they are non the dangerous plants we once thought they were. Turns out, poinsettias are bitter tasting—which is skillful because this helps prevent ingestion, and enquiry shows it would take a huge quantity to crusade issues.

Y'all tin't, really. When a poinsettia has blood-red leaves, it's in a flowering stage which last several weeks and sometimes months. Later that, the plant needs a residual period where it can build up energy to (we hope) bloom once once again.

While you cannot force the leaves to stay scarlet (or whatsoever color they were ) continually, you can provide the right conditions to encourage a repeat performance equally described to a higher place.

How practise yous prune a poisettia?

Mostly, we cut back or prune a poinsettia in late jump when the constitute is finishing up its rest menses.

Using clean pruners or fine snippers, working 1 stem at a fourth dimension, cutting each one back to approximately four-inches, just above a leaf node.

Always wear gloves because poinsettias ooze sap that is irritating to skin and eyes.

How practice you revive a poinsettia?

That's a tough i! If the plant was shocked, either by temperature swings, overwatering or underwatering, or wind (which dries out plants), it may exist too late.

Yous can effort pruning away whatever dead or dying parts, identify it in a draft-free sunny location, and water only when the soil is dry to touch.

Sometimes they drop leaf after blooming, other times they are giving up the ghost.
You'll know in a month or two if it's toast or there is new life fix to leap back.

How can I brand my poinsettia turn white?

Yous can't. Poinsettias are bred in different colors. If yous want a white 1, you become a white one. A crimson poinsettia, for example, cannot exist forced to plow white.

That said, insufficient light tin can produce faded versions of the original colors.

Can I grow more poinsettias from cuttings?

Yeah. But first be certain that the plant is not patent protected so you know it is legal to do and so.
