Poinsettia Light Requirements (Gardener’s Guide)

When choosing the location for your poinsettia, it’s important to take into account its light requirements.

poinsettia light requirements

Generally, Poinsettia plants can tolerate dappled light but need at least 1 or 2 hours of direct sunlight each day.

However, they do prefer bright-filtered light, preferably from a window. It should be placed away from warm draughts, as they are sensitive to them.

If you plan on planting a potted poinsettia, make sure the location is bright, but not too bright.

Poinsettias tolerate only one to two hours of direct sunlight

During its high-growth period, poinsettias struggle to produce new growth. When they don’t produce new growth, they may be receiving insufficient light.

Poinsettias lean towards the source of light, such as a window or a light bulb. This will lead to browning of the leaf margins, which will eventually spread to the rest of the plant.

For optimal growth, poinsettias need at least six hours of direct sunlight per day. Keep them near a sunny window, but make sure they aren’t placed too close to a drafty window.

Unlike most other houseplants, poinsettias don’t tolerate drastic temperature changes.

Cold air drafts and extreme temperature fluctuations can cause leaf bracts to fall off. They’ll become scraggly if this happens.

Once winter has passed, move poinsettias to a shady area, but make sure they have protection from direct afternoon light. If they’re placed outdoors, they can tolerate half-strength fertilizer during the summer.

Be sure to pinch off the branches if you notice them getting out of hand. You should also check for pests, especially aphids, and spider mites.

A homemade insecticide solution made of water and dishwashing soap can kill the bugs that may be feeding on poinsettias.

To care for your poinsettia, keep in mind that they are tropical plants. Therefore, their ideal conditions include warm temperatures, a high humidity level, and ample light.

However, you may want to avoid watering them excessively because it will result in root rot.

Keeping them in a cold room can make them less happy. However, it’s still important to check for regular watering, especially if they are growing in pots or troughs.

If you’re growing poinsettias indoors, remember that the only time they tolerate direct sunlight is in the morning and early afternoon.

They require bright concentrated light to grow well and to build a food reserve. The intensity of sunlight decreases dramatically during winter, and poinsettias enter dormancy. And don’t forget to give them enough shade in the evening!

To get the best results, choose a room with at least 6 hours of indirect sunlight. Direct sun exposure can damage the flower and damage the plant.

However, poinsettias will grow happily in a sunny room with indirect sunlight for up to six hours a day. But be sure to protect them from too much sun, which is bad news for the plant. You don’t want to ruin your beautiful poinsettia by overwatering it.

A poinsettia is easy to grow. You can either keep it inside or move it outside in the spring. As long as it gets bright indirect light, poinsettias should remain green all summer.

If you don’t mind being green, it’s perfectly fine! They’re not suited for a sunny window, so make sure to choose a plant with filtered, indirect sunlight.

Poinsettia tolerates dappled light

In most cases, poinsettias do best in bright diffused sunlight. They thrive in six to eight hours of light per day but can survive with less.

Direct sunlight will burn the leaves and bracts, but indirect light will produce the best growth. You can place the poinsettia on a window sill or place it near a sunny window for dappled light.

Plants require 65 to 75 degrees Fahrenheit. While they do not mind a slightly lower temperature, they do not like drafts or very little light. Similarly, their leaves will become damaged if they receive too little humidity.

To make sure that the humidity levels surrounding the poinsettia are high enough, you can purchase a small space humidifier. If you’d rather not use a humidifier, try using a portable one.

When choosing a location for your poinsettias, choose one that has morning or dappled light. The poinsettia is better in bright spots with some shade in the afternoon. It may require morning shade in sunny areas, but it can tolerate dappled light in these conditions. During the winter, place your poinsettia in a sheltered spot, away from cold drafts.

When it comes to sunlight, choose a location with six to eight hours of bright sunlight per day. Direct sunlight will cause the leaves to yellow and become translucent. It will also stunt new growth. If you don’t have this kind of window, try hanging light curtains or blinds to protect the plants from the direct sunlight. When you’ve selected the perfect location for your poinsettia, you can be assured that it’ll thrive.

If you’re planning to plant a poinsettia in a sunny location, make sure you move it into full sun as soon as nighttime temperatures reach fifty degrees Fahrenheit.

If the plant is still in its pot, prune the stems and promote side branching. Cut back the old flowering stems in early March.

Side shoots will form below the bracts and grow above the old flowering stems. The new growth will come from the buds in the leaf axils.

After the poinsettia blooms in mid-December, it’s time to move it out of direct sunlight. Place it near a window and water it regularly. It should return to bloom by December 15th. During this period, check the roots for any signs of root rot or magnesium deficiency.

Also, do not forget to fertilize the plant regularly to avoid any unwanted pests. If the blooms fail to form, the plant may need a dose of magnesium.

Over-watering is another common problem with low-light conditions. Poinsettias need 14 hours of darkness each day in November and eight hours of darkness in December.

Without adequate darkness, poinsettias will not bloom. Overwatering will also invite diseases and pests.

Excess water in the soil dries up on the margins of the leaves. These brown spots are symptoms of edema or pest damage.

Poinsettia and direct sunlight

If your house gets lots of direct sunlight during the day, poinsettias can withstand one to two hours of it.

However, too much sunlight will bleach the foliage, burn the edges and cause the bracts to lose their color. While poinsettias can survive a little bit of direct sunlight, they thrive in dappled light.

To find out how much direct sunlight your poinsettia will tolerate, use a hand-shadowshadow test. A blurry hand shadow means your poinsettia is not exposed to direct light.

During the day, poinsettia leaves bend towards the light source. If the plant is not receiving enough light, the foliage will curl and become crispy brown on the sides and tips. If it does not receive enough light, the plant will become leggy and floppy.

Excess sunlight can also dry out the soil, causing it to become bone dry, and the bracts to turn yellow. To avoid this, make sure that the light source is spotty and that there is at least 14 hours of darkness during the night.

The light from north-facing windows is the least beneficial, as it is dim during spring and summer. However, this is not an issue in the winter as poinsettias are not bothered by direct sunlight, so it’s OK to place them near a west-facing window in the afternoon or in a window that gets indirect light.

The best place for your poinsettia is a room with a southern exposure, where the light is evenly distributed.

As soon as you spot a sunny spot in your flower bed, you can move your poinsettia outside. However, make sure that it is protected from freezing temperatures, or else the plant will grow roots and rot.

If you do decide to grow your poinsettia in the winter, it will be better suited for an indoor flower bed. Just be sure to water and fertilize it regularly. If you have enough time, your poinsettia will grow bigger flowers than they normally would!

The temperature needs to be between 60 and 75 degrees Fahrenheit during the day and 65 degrees during the night. It should not be placed near air vents or radiators.

They will be stressed in these extreme temperatures, so it’s important to keep the room warm. You should prune the poinsettias at least once a week to promote side branching and stout growth.

Once you prune your poinsettias, move them into a sunny window, and increase the amount of water that you give them.

Conclusion

Although poinsettias can be grown as shrubs, they do not survive the cold winter weather that is common in most growing regions.

It must be treated like a houseplant. They do best in temperatures between 60 and 70 degrees F, and they will be happier with the cooler temperature.

They will only bloom if they are kept near cool spots. However, if you do place them in a chilly room, they can overheat and die.
