When the holiday season is over, people often throw away the poinsettias without noticing that the tree is still full of life. With just a little time and care, you can save the poinsettia and it will return to its splendor the following year. Start by pruning away dead leaves to make room for new shoots. Be sure to provide the plant with enough water and indirect sunlight, and if you live in a favorable climate, plant the plant in the ground outdoors at the right time. Your poinsettias will be full and vibrant again when winter comes.
Steps
Saving poinsettias after winter
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/89/Revive-a-Dying-Poinsettia-Step-1-Version-2.jpg/v4-728px-Revive-a- Dying-Poinsettia-Step-1-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/89/Revive-a-Dying-Poinsettia-Step-1- Version-2.jpg/v4-728px-Revive-a-Dying-Poinsettia-Step-1-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Place the plant in a place where it receives a minimum of 6 hours of sunlight each day. As soon as you decide to save the poinsettia, move it to a well-lit location in your home. Ideally, places with indirect sunlight, such as east or west-facing windowsills, or open plan living rooms. [1] X Research Source
- Poinsettias are light-loving plants. They need a lot of indirect light to survive.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/0/0d/Revive-a-Dying-Poinsettia-Step-2-Version-2.jpg/v4-728px-Revive-a- Dying-Poinsettia-Step-2-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/0/0d/Revive-a-Dying-Poinsettia-Step-2- Version-2.jpg/v4-728px-Revive-a-Dying-Poinsettia-Step-2-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Water the plant thoroughly every few days. The amount of water needed will depend on the plant’s needs, the size of the pot, and the temperature of the surrounding environment, but the rule of thumb is to water just enough to keep the soil moist. Re-water as often as needed, remembering to let the soil dry out between each watering. [2] X Research Source
- Most medium-sized plants will need about 180 ml of water, watered every 1-2 days.
- Be careful not to over-water the poinsettia. Soggy soil will lead to root rot and other diseases that can easily kill plants. [3] X Research Sources
- Make sure the pot has a drainage hole in the bottom. If the pot does not have a drainage hole, you need to replace the pot or drill a hole in the bottom of the pot.

Prune dead foliage. Inspect the poinsettia for shriveled or faded old leaves and pry them off by hand. Remember to pick up all the fallen leaves in the potted plant. Leaves that look healthy should be left. [4] X Research Sources
- After pruning, poinsettias can look like bare branches. This is completely normal. The colorful foliage will reappear when the tree awakens in the spring from hibernation.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/5/5d/Revive-a-Dying-Poinsettia-Step-4-Version-2.jpg/v4-728px-Revive-a- Dying-Poinsettia-Step-4-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/5d/Revive-a-Dying-Poinsettia-Step-4- Version-2.jpg/v4-728px-Revive-a-Dying-Poinsettia-Step-4-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Prune branches that have begun to rot. Look for old branches that appear diseased or discolored. Use pruning pliers to cut off these branches at least 1.3 cm below the damaged area. You may have to cut off all existing branches, leaving only new shoots at the base of the tree. [5] X Research Sources
- Pruning will also help stimulate healthy plants to sprout new shoots. [6] X Research Sources
- Throw the branches and leaves in the compost bin to turn them into organic material that you can feed to the poinsettias as they begin to grow back. However, if the branches are infested with pests, throw them in the trash instead of compost.
Stimulates plants to sprout in spring and summer
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/ea/Revive-a-Dying-Poinsettia-Step-5.jpg/v4-728px-Revive-a-Dying-Poinsettia- Step-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/e/ea/Revive-a-Dying-Poinsettia-Step-5.jpg/v4-728px-Revive- a-Dying-Poinsettia-Step-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Maintain a stable temperature in the range of 18-24 degrees Celsius. The most suitable temperature for poinsettias is also in the comfortable range for humans. Fortunately, this means that the plant will be content to be in any room of the house. [7] X Research Sources
- Place plants away from windows and doors that are frequently left open. Poinsettias do not tolerate drafts. [8] X Research Sources
- Do not place plants near fireplaces, heaters, or vents.
- Avoid adjusting the thermostat too suddenly when the outdoor temperature fluctuates.

Fertilize the plant once a month during spring. Fertilizer is an essential element to add essential nutrients to the soil. Balanced water-soluble houseplant fertilizers are the safest choice for delicate plants like poinsettias. You should always use the exact dosage indicated on the label for the particular product. [9] X Research Source
- You can also use organic fertilizers such as garden compost or earthworm manure to fertilize your plants. [10] X Research Source
- The best time to fertilize is right after watering the plant, while the soil is still moist. Poinsettias roots can be damaged if you fertilize the plant when the soil is dry. [11] X Research Source
- Fertilize the poinsettia once a month during its strongest growth period.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/c4/Revive-a-Dying-Poinsettia-Step-7.jpg/v4-728px-Revive-a-Dying-Poinsettia- Step-7.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/c4/Revive-a-Dying-Poinsettia-Step-7.jpg/v4-728px-Revive- a-Dying-Poinsettia-Step-7.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Move the plant outdoors to a place with indirect sunlight. Leave the plant outside for a few hours on warm afternoons. Place the plant in a spot with speckled shade to prevent it from overheating. A covered yard or flower beds under the trees make a great outdoor home for poinsettias. [12] X Research Source
- Slowly acclimatize the plant to outdoor conditions. Usually, it’s best to start out for a few hours early in the morning, then gradually increase 1-2 hours a day until the plant has enough to endure the afternoon.
- Find a spot in the garden that gets more morning sun and more shade in the afternoon.
- You may need to water the plant more often when it is out in the sun for a long time. Dropping, yellowing, or curling leaves can be a sign that the plant has been outdoors for too long. [13] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/6e/Revive-a-Dying-Poinsettia-Step-8.jpg/v4-728px-Revive-a-Dying-Poinsettia- Step-8.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/6e/Revive-a-Dying-Poinsettia-Step-8.jpg/v4-728px-Revive- a-Dying-Poinsettia-Step-8.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Cut the branches to about 15-20 cm in spring or summer. When the weather starts to warm up, you should probably cut back about 1/3 (or even half) of the size of the poinsettia. Selective pruning is a necessary step to stimulate the plant to sprout, and the tree will grow more luxuriantly. By cutting the branches short, you channel the plant’s energy into flowering and new foliage. [14] X Research Source
- If you want to delay a major pruning, you can wait until midsummer, when the poinsettias reach their maximum size. [15] X Research Source
Stimulate poinsettias to bloom again
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/13/Revive-a-Dying-Poinsettia-Step-9.jpg/v4-728px-Revive-a-Dying-Poinsettia- Step-9.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/13/Revive-a-Dying-Poinsettia-Step-9.jpg/v4-728px-Revive- a-Dying-Poinsettia-Step-9.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Cover the plant overnight during fall to stimulate flowering. To produce vibrant bracts after dormancy, poinsettias will need 12-14 hours of absolute darkness at night between September and October. Use a black cloth bag or carton- The cardboard is applied to the tree every night when the sun goes down and opens the next morning when it is time for the tree to receive sunlight. [16] X Research Source
- Consider putting the plant in a closet or basement after covering it with a black cloth. Just a little ambient light is enough to keep the plant from flowering at the right time. [17] X Research Source
- Poinsettias are light cycle dependent plants, which means that the amount of foliage that grows will be determined by the number of hours without light per day.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/ba/Revive-a-Dying-Poinsettia-Step-10.jpg/v4-728px-Revive-a-Dying-Poinsettia- Step-10.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/ba/Revive-a-Dying-Poinsettia-Step-10.jpg/v4-728px-Revive- a-Dying-Poinsettia-Step-10.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Replant the poinsettia into a larger pot. Your resurrected poinsettias may eventually grow larger than the original pot. When the plant starts to stop sprouting, move it to a new pot to give the roots plenty of room to spread. Be careful not to cut the delicate roots when pulling the plant out of the old pot. [18] X Research Sources
- You can use any well-balanced potting mix to fill the new pot. [19] X Research Source
- Continue watering and fertilizing the plant as usual after you have transferred the plant to a new pot.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/2/26/Revive-a-Dying-Poinsettia-Step-11.jpg/v4-728px-Revive-a-Dying-Poinsettia- Step-11.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/2/26/Revive-a-Dying-Poinsettia-Step-11.jpg/v4-728px-Revive- a-Dying-Poinsettia-Step-11.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Use insecticides to repel insects. Common pests such as aphids and whiteflies often live on poinsettias and feed on leaves. The best way to limit the damage they cause is to periodically spray with a mild organic insecticide, such as neem oil or insecticidal soap. You can catch by hand if there are only a few intruders. [20] X Research Source
- Remember that organic pesticides are milder, so they usually need to be reapplied more often than chemical products.
- If you don’t like the idea of using pesticides, you can try making a solution at home by mixing all-natural liquid soap with warm water in a spray bottle and knocking out the pests every time they appear. [21] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/8d/Revive-a-Dying-Poinsettia-Step-12.jpg/v4-728px-Revive-a-Dying-Poinsettia- Step-12.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/8d/Revive-a-Dying-Poinsettia-Step-12.jpg/v4-728px-Revive- a-Dying-Poinsettia-Step-12.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser -output”></div>”}
Bring the plant indoors when the temperature starts to drop. By mid-autumn is when the weather starts to become unsuitable for poinsettias to be outdoors all day. Find a warm spot in your house where the plant can enjoy 6-8 hours of indirect sunlight each day. If it has survived to this stage, it is likely that the tree will thrive for another season without difficulty. [22] X Research Source
- If you live in a particularly warm climate, you can leave poinsettias outdoors throughout the fall and winter. The outdoor temperature should always be above 10 degrees Celsius. It is important to protect the plant from frost and freezing temperatures for long periods of time.
Advice
- With proper care, poinsettias can live for many years.
- Protect poinsettias from strong winds and heavy rain, no matter what season of the year.
- You can collect the cut flowers from the first pruning and put them in a pot of clean water instead of throwing them away.
- Poinsettias are often used as Christmas decorations.
- Poinsettias do not like the wind; Place the tree in a quiet place.
Warning
- Always wear gloves when pruning poinsettias. The sap from the tree can cause irritation in contact with the skin.
Things you need
- Tree pruning pliers
- Water-soluble fertilizer for indoor plants
- Organic fertilizer (optional)
- Wide planter pot
- Ready-to-use potting mix
- Bag or box to cover the plants at night
- Gentle Organic Pesticides
- All-natural liquid soap, water and spray (optional)
