Overall, the poinsettia is a safe plant and is among the best indoor clean air plants. These plants are a great addition to your home because they may both purify the air and enhance its appearance. Poinsettias eliminate any traces of formaldehyde from insulation, supermarket bags, particleboard, and other home goods that may have been exposed to it. This results in less pollution and cleaner air.
Two plants can purify 100 square feet of space in a room with an average 8-foot ceiling, according to extensive research on clean air plants conducted by NASA. You might want to keep more plants in your house after reading this, but even a small bit helps!
How long do poinsettias stay fresh inside a home?
A potted poinsettia can live in your home for two to three months if it is properly cared for. The difficulty of caring for a poinsettia long after Christmas in the hopes of a second bloom for the next holiday, however, may appeal to certain home gardeners with a particularly green thumb.
Where in my home should I place poinsettias?
- Place the plant near a south, east, or west window for adequate indoor lighting.
- Outdoor lighting: 4 to 6 hours each day of partial sun.
- Temperature:
- Ideal indoor temperatures range from 65 to 70 degrees F.
- Place poinsettias away from drafts, heat vents, fireplaces, fans, space heaters, and other areas where the air may be drying out or fluctuating in temperature.
- If exposed to temperatures below 50 degrees F, poinsettias will be harmed.
- Poinsettias will perish in subfreezing conditions.
- Keep the soil wet.
- If you can lightly touch the soil surface and it feels dry, water the plant. If you lift the container, it should feel light. Never let poinsettias dry out to the point that they wilt.
- Before watering, remove from ornamental foil or the outer container.
- Ensure that your plant is in a pot with adequate drainage.
- Place the plant in the sink and give it a good watering, letting the water drain entirely.
- Never let the water in poinsettia pots get too high. Plant roots will decay with constant moisture.
- Keep watering as necessary. from January to March.
- During the holidays, you don’t need to fertilize your poinsettia.
- once you notice fresh growth on your plant, begin fertilizing it (new green leaves, stems, bracts).
- Use an all-purpose household plant fertilizer when fertilizing.
- It should be diluted with water by half the suggested amount.
- Feed your poinsettia every three to four weeks to maintain plant health and supply the nutrients needed for new growth.
Transplant your poinsettia into a larger pot (approximately 2 to 4 inches larger than the original pot) or onto a garden plot that receives some afternoon shade in late spring or early summer.
- Use a soil mixture in pots that has a significant amount of organic material, like peat moss. Ascertain that the new pot has excellent drainage.
- Plant in a garden bed that has well-drained soil and receives 4 to 5 hours of direct sunlight per day. Peat moss or compost are good organic materials to include into the soil. This will assist keep the soil moist and provide the roots with a favorable environment for growth.
- After transplanting, thoroughly water your poinsettia.
Poinsettias can be cultivated as lovely green plants, but most people prefer to recolor their green ones so they’re festive for the holidays.
It is a difficult chore because it calls for depriving the plant of light for a while while yet maintaining its health. Chlorophyll, the pigment that gives plant parts their green color, cannot be produced by the plant as a result of the light shortage. Depending on the poinsettia variety, this causes the bracts to transform to red, pink, or white.
Author of the book Caring for Your Poinsettia Year-Round and Extension professor emeritus at the University of Vermont, Dr. Leonard Perry created an easy-to-use poinsettia care calendar based on the seasons.
Does the poinsettia grow indoors?
Return the plant to a bright spot in the spring and give it lots of water. At least 6 inches (15 cm) should be removed from the pot’s rim on all canes (branches). Repotting the poinsettia with the same soil might also be a smart move. While poinsettias may be kept indoors all summer long, many people prefer to transfer them outside and plant them in a sunny but protected section of the flower garden by burying the pot in the earth. Any way is acceptable.
Pinch out the tips of the new growth once it has grown between 6 and 10 inches (15–24 cm) to promote branching. Up until the middle of August, this can be done once per month. Bring the poinsettia indoors once the fall nights start to grow longer.
For the management of poinsettia plants, light becomes essential from around September to November. Poinsettia plants need prolonged periods of nighttime darkness to promote blooming (about 12 hours). As a result, either relocate the poinsettia to a spot without any nocturnal lighting or cover it with a box. The plant needs a lot of light during the day to absorb the necessary energy for blossoming. Additionally advised are warmer days (65-70 F/18-21 C) and milder nights (55-60 F/13-16 C). Once blooming has begun, provide areas that are somewhat chilly, humid, with plenty of moisture and bright, indirect light.
How frequently should a poinsettia be watered?
Place the poinsettia in a well-lit location of your house that is away from drafts and heating vents. Once a week, or when the soil seems dry to the touch or the pot gets light, water the poinsettia. Before replanting the plant, give it a good soak in the sink and let the water drain.
After Christmas, what should I do with my poinsettia?
Okay, to be quite honest, I don’t have the time to take care of poinsettias year-round in the hopes of getting them to bloom again in time for the upcoming holiday season. I trust on the growing professionals at Stanley’s Greenhouse to do it for me!
Here are the measures you may do to help your poinsettias bloom once more for Christmas if you have a green thumb, enjoy a challenge, and a lot of time to invest in the project.
- Check to see if your poinsettias are getting adequate water, as you have during the holiday season, but take off any ornamental sleeves or paper wrappings at the base of the plants so you may water freely without the plants standing in water.
- Put your poinsettias where they will get at least 6 hours per day of bright, indirect sunlight.
- Pinch back the stems to 6-8 inches in mid-April, then position the plants in a bright area. You can apply a liquid fertilizer to make sure the plants have adequate minerals, especially calcium, when new growth starts.
- Your poinsettias can be planted outside when the nighttime low in spring is at least 50 degrees. Start them off in a shaded area and move them to full light once they’ve become used to it. Keep in mind that during their growing season, poinsettias need bright sunlight and warm climates because they are native to Mexico and Guatamala.
- Repot your poinsettias in a bigger container to promote deeper root growth.
- Don’t prune your poinsettias after September 1 to preserve their holiday flowering.
- Bring the plants inside after nighttime lows reach 55 to 60 degrees, and position them in a bright spot.
- Your poinsettias will require 14 consecutive hours of darkness followed by 6-8 hours of bright sunlight beginning in October in order to bloom in time for the holidays.
- If everything goes according to plan, you will be able to enjoy poinsettias in late November, just in time for the holiday season.
How is a potted poinsettia maintained?
Because they bloom in the middle of winter and because bracts, or persistently colored leaves, rather than flowers, are what give poinsettias (Euphorbia pulcherrima) their beauty, they are common winter houseplants. It is simple for nurseries to get them into color in time for the holidays because they bloom spontaneously throughout the long winter nights. Poinsettias’ beauty can endure through Thanksgiving, Christmas, and occasionally even Valentine’s Day. Some gardeners want to conserve the plants so they will bloom again the following winter since they are dissatisfied with this prolonged season of interior beauty. If you take good care of your poinsettias, they will bloom every year if you keep them.
Withhold water progressively until the plant’s leaves start to turn yellow or until it is no longer desired as an ornamental. The leaves will dwindle and drop. The last to disappear are the bracts, which are the vivid leaves that sit below the actual flowers. The parts of the plant are shown in Figure 1. Store the plant in its pot in a cold (50 to 60F), dry, and dark location once all the leaves have fallen. Water the plant just enough to prevent the stems from withering, keeping it on the somewhat dry side.
Parts of a poinsettia, Figure 1. The colorful bracts are the prominent feature, which is typically thought of as the flower.
Bring the plant out of storage in April or May. Six inches above the soil line, cut the primary stems. Take the plant out of the pot, then gently wash the roots to remove the old soil. Repot the plant in new, well-draining potting soil. If the soil is dense and retains a lot of moisture, poinsettias might develop stem and root infections. Give the soil a good soak, and then let all the extra water drain away. For fresh growth, put the plant in a warm, sunny location. Maintain a high humidity level to promote quick new growth. Apply a weak fertilizer solution (one tablespoon of a soluble fertilizer, such as 20-20-20 or its equivalent, per gallon of water) on a monthly basis once the plant is actively growing.
The pot should be placed in a protected, sunny bed once the risk of frost has passed. During the hottest portion of the day, light shade is excellent. To stop roots from spreading into the surrounding soil, lift the pot every so often. Repot the plant into a larger pot if the roots become entangled. Keep an eye out for bugs and quickly get rid of them.
Water and fertilize the poinsettia plant frequently during the summer to keep it actively developing. Apply water freely to thoroughly hydrate the soil when the top seems dry, then let the extra water drain away. Don’t add any more water until the soil’s surface is once again dry.
Pinch the tips of new shoots back, leaving at least two nodes on each new shoot, to produce a bushy plant (Figure 2). Pinch fresh shoots through the end of August. Eliminate all weak stems so that only a handful of the stronger ones grow.
Figure 2. Poinsettias are “pinched back” to produce a bushy plant. Each twig has its tip removed (pinched) to leave only the nodes. Additionally, the nodes’ emerging new shoots are constricted.
Try growing poinsettias from stem cuttings instead of pinchings if you want more plants. Cut off 4 to 6 inches for roots when the new growth reaches a height of 8 to 12 inches (Figure 3). To ensure that the plant may continue to generate food, leave at least two leaves on both the parent stem and the cuttings. Cut the stem in the morning, then soak it in lukewarm water for an hour to stop the “bleeding.” To improve the likelihood of success, apply rooting hormone to the base of cuttings. Put the cuttings in a wet, well-drained rooting media, such as a perlite-peat moss mixture. Increased humidity will speed up roots. Cuts should be placed in bright, but not direct, light. When the new roots are about 1/2 inch long, pot the newly rooted cuttings in a well-drained soil. These plants require the same maintenance as their parent plant.
All rooted cuttings and the parent plant will bloom at the same time. Larger blooms will be produced by the thicker cuttings. Till the end of August, take as many cuttings as you like, but keep in mind that only strong stems grow vigorous plants.
Bring the plant indoors to a south window with ample sun as the cool fall weather starts. The bracts (colored leaves below the blooms) on poinsettias develop their darkest color in good light, and they thrive best in full autumn sun. While enough ventilation is crucial, keep drafts away from the plant. The lowest leaves of the poinsettia plant can become yellow and drop off the plant due to drafts, low temperatures, soggy soil, and drought. It is advised to keep indoor temperatures between 60 and 65 degrees Fahrenheit throughout the daytime. The plant is prone to flower later if the nighttime temperature is very high or low.
A true short-day (or long-night) plant is the poinsettia. This means that for the plant to develop flower buds, it must spend roughly 14 hours per day, seven days per week, in complete darkness. Make sure the poinsettia doesn’t receive artificial light after sunset starting in late September or early October. One night’s worth of sporadic illumination from a single light bulb may be sufficient to prevent or delay blossoming. If at all feasible, place the plant from approximately 5:00 p.m. to 7:00 a.m. every day for four weeks in a dark room, a closet, or under a completely light-proof cover.
Keep in mind to water the plant when the soil surface becomes dry and place it in a sunny window during the day. Now, watering will likely be less frequent. Up until mid-December, keep fertilizing it every month. At roughly 65F, the opened flowers stay open the longest.

How can I preserve the life of my poinsettia year-round?
Mexican natural plants include poinsettias. Because they are short-day plants that need lengthy evenings to initiate their color shift, they flourish throughout the holiday season. These plants have colorful bracts, which are actually leaves, not flowers, with red being the most typical bract color. The bracts’ red or green buttons in the middle are the flower buds, which open to reveal a little yellow flower. Healthy poinsettias have foliage all the way down to the base and dark green leaves beneath the bracts. Your poinsettia can enliven your home for months if given the right attention and care. Observe these suggestions.
When moving the plants, in particular, keep them from freezing. Put them in a well-lit area that is free from drafts. At night, they prefer temperatures between 55 and 65 degrees, and during the day, 65 to 70 degrees. Poinsettias should not be kept in chilly areas or exposed to temperatures below 50 degrees Fahrenheit.
When the soil is dry 2 to 3 inches down, water poinsettias. The plants are quite susceptible to overwatering, and if kept too wet, root rot will appear soon. Thoroughly wet the pot, letting extra water run off into the sink.
To keep plants healthy throughout the holidays, apply an all-purpose, water-soluble fertilizer once a week. Reduce watering and fertilizer once the bright bracts have fallen off to give the plants time to recover. Only a few leaves should be left on the poinsettia after trimming it back.
Poinsettia bracts can be kept alive until about March or April with the right care. Cut the plant back after they start to fall, leaving around six buds. The plant will resemble a stick for the first several weeks after planting. It will start to leaf out again in May if you continue to water and fertilize it as previously.
When the risk of a freeze has passed in the spring, poinsettias can be moved outside for an intriguing, uncommon outdoor plant. The plant can be used all summer long if it is placed in a shaded area.
Cut the plant back in mid-July and early-September to encourage branching if you want to keep it small and compact.
Put the plant in complete darkness as soon as the sun goes down, starting on October 1st, giving at least 14 hours of darkness. The plant can either be covered with a bag or left in a closet all day. It will begin to turn color by the end of November, allowing you to enjoy it for another season.
