Poinsettias are popular holiday plants, especially during Christmas. With their vibrant red, pink, or white bracts, they add a festive touch to homes. Many people toss them out after the holiday season, but with the right care, you can keep your poinsettia thriving year-round and even get it to bloom again the following Christmas. This guide will walk you through everything you need to know about how to grow poinsettia, from the type of pot and soil to light, water, fertilizer, bloom care, and tips for reblooming.
Choosing the Right Pot for Your Poinsettia
When you bring your poinsettia home from the store, it often comes in a plastic pot with drainage holes. You can keep it in this pot for a while, although remove the plastic outer wrap. But if you want to transplant it into something more decorative, make sure the new pot also has good drainage. Poinsettias don’t like sitting in water, as it can lead to root rot.
Choose a pot that is only slightly larger than the one your poinsettia came in. A pot that is too large will hold excess water, which can harm the plant. Terra cotta pots are a great choice because they allow for good air circulation and water evaporation. Make sure to place a saucer under the pot to catch any water that drains out.
Best Soil for Poinsettias
Poinsettias need well-draining soil to thrive. A mix of regular potting soil with perlite or sand works well. The soil should be loose enough to allow water to drain quickly, but also rich enough to provide the nutrients your plant needs. You can use a pre-mixed potting soil formulated for indoor plants or create your own mix. Avoid using heavy garden soil, as it retains too much water and can suffocate the roots.
Light Requirements for Poinsettias
After the holidays, your poinsettia will need bright, indirect light to continue growing. Place it near a window that gets plenty of sunlight, but make sure the plant isn’t exposed to direct sunlight, which can scorch its leaves. A south, east, or west-facing window is ideal. Rotate the plant every few days so that all sides receive equal light, helping it grow evenly.
Poinsettias are tropical plants and love warmth. Keep them in a room where the temperature stays between 60°F and 70°F. Avoid placing them near drafts, heaters, or cold windows, as sudden temperature changes can stress the plant.
Watering Your Poinsettia
Watering is key to keeping your poinsettia healthy. Water the plant when the top inch of soil feels dry to the touch. When you water, do so thoroughly until water drains out of the bottom of the pot. Be sure to empty the saucer after a few minutes, as poinsettias don’t like sitting in water.
If the soil stays too wet, the roots can rot, causing the leaves to wilt and fall off. On the other hand, if the plant is too dry, the leaves will start to droop and curl. Regularly check the soil moisture to strike the right balance.
Fertilizing Poinsettias
After the holiday season, your poinsettia will enter a resting phase. During this time, you don’t need to fertilize it. Once new growth starts in the spring, begin feeding it with a balanced, all-purpose fertilizer. A 10-10-10 fertilizer works well.
Feed the plant once every two to three weeks during the growing season. Stop fertilizing in late summer, as the poinsettia prepares for its blooming phase. Avoid over-fertilizing, as this can cause salt buildup in the soil, which may damage the roots.
Post-Bloom Care
Once the bracts (the colorful leaves) begin to fade and fall off, your poinsettia has finished its bloom cycle. Now, it’s time for a little maintenance to prepare the plant for the next blooming season.
- Pruning: After the bracts fall, prune the plant back to about 6 inches tall. This will encourage new growth. Be sure to remove any dead or damaged leaves and stems. Pruning helps the plant focus its energy on developing healthy new stems.
- Resting Period: After pruning, reduce watering and stop fertilizing. Place the poinsettia in a cool, dark area for about 8-10 weeks. During this time, the plant will rest and prepare for new growth. Water sparingly, just enough to keep the soil from completely drying out.
- Returning to Light: After the resting period, bring the poinsettia back into a sunny room and resume normal watering and fertilizing. You should see new growth appear within a few weeks.
Getting Poinsettias to Rebloom
Getting a poinsettia to rebloom can be tricky, but it’s doable with some patience and care. Starting in early fall, the plant needs a strict light regimen to trigger blooming. Poinsettias are short-day plants, meaning they require long periods of darkness to start producing their colorful bracts.
Here’s how to do it:
- Light and Dark Cycle: Starting in late September or early October, place your poinsettia in complete darkness for 14-16 hours each night. You can cover it with a box or place it in a closet. During the day, bring it back into bright, indirect light for about 8 hours. Repeat this process daily for 8-10 weeks.
- Maintain the Routine: Be consistent with this light-dark cycle. Any exposure to light during the dark period can delay blooming. By late November or early December, you should start to see new bracts forming.
- Temperature Control: Keep the plant in a room where the temperature stays between 65°F and 70°F. Avoid cold drafts or heat sources, as temperature fluctuations can interfere with blooming.
Happy Poinsettia Gardening!
With the right care, you can enjoy your poinsettia for many years. By providing the right pot, soil, light, water, and fertilizer, and following a strict care regimen after the bloom, you’ll increase your chances of seeing those beautiful bracts reappear year after year. The process of getting a poinsettia to rebloom can be a rewarding gardening challenge, and it will add that familiar Christmas cheer to your home once again.
