Tropical houseplant anthurium, commonly referred to as flamingo flower, is well-liked and comparatively simple to maintain. Although they are rare, illnesses can occasionally cause dark patches to appear on the plant’s leaves. After years of anthurium cultivation, we at last ran into the same problem. We discovered what was wrong and what to do about it because we didn’t want to lose our plant.

Why then do the leaves on your anthurium have brown spots? Leaf blight, also known as leaf spot, is the most typical cause and is brought on by bacteria that infects the leaves. Brown spots, however, can also result from dietary deficiencies or too much sunlight. Here’s how to resolve these issues and repair your anthurium.

If you discover bacterial illnesses and vitamin deficits early enough, they can both be cured. If the brown spots are little and haven’t spread past the leaves, it might still be possible to salvage your plant.

How frequently do I need to water my anthurium?

H2O and Humidity

Low to medium water requirements apply to this houseplant. In between waterings, let the soil to dry out. If you reside in a hot climate, water your lawn once every two to three days; if it rains frequently, water as needed. The anthurium needs appropriate drainage most of all.

Why are my plant’s leaves turning brown?

Dry brown patches can be caused by underwatering, overwatering, and a lack of humidity, especially on the tips of leaves or the edges of leaves.

Solution: Dig your finger into the ground. If it’s completely dry, you’re probably submerged. You’re probably overwatering if it feels wet. If it only feels very little damp, dry air is usually the problem; spray it more frequently.

What does an anthurium look like when it is overwatered?

Root rot can occur if your Anthurium is overwatered. How does that appear? The stems will become brown, and the roots will be mushy. Issues with soil quality or watering frequency could be the cause of this.

What causes the browning of leaf tips?

Typically, underwatering, sunburn, or overwatering are the causes of browning leaves.

The soil possibly grew too dry for an extended period of time between waterings if the leaf tips are turning brown and hard. The plant may lose leaves as a result of this. This does not necessarily imply that you are regularly underwatering because the browning may have only occurred once. Although the brown leaf tips won’t turn green again, you can trim the brown margins to restore the plant’s healthy appearance. Go here to learn more.

It may also be a symptom of overwatering if you see brown patches all over the leaves. You’ll typically notice some yellowing of the leaves as well when the plant is overwatered. Go here to learn more.

If you see brown stains in the middle of the leaves, it may be because the leaves are receiving too much direct sunshine. Some plants are readily burned by direct sunlight and are sensitive to it. If this is the case, try shifting your plant to a spot where it won’t be exposed to the sun’s glare.

– If you move your plants from indoors to outdoors in the summer without acclimating them to direct sunshine, this is usually what happens.

Should I remove leaves that have brown spotting?

We’ve experienced our fair share of brown, decaying leaves as we’ve learned how to properly care for various home plants over the years. We weren’t sure at first whether to take them out or leave them. Here is what we’ve discovered works the best.

Do you need to remove the dead leaves? Yes. Your indoor plants should have brown and withering leaves removed as quickly as possible, but only if they are more than 50% damaged. By removing these leaves, the plant looks better and the healthy foliage that is left can receive more nutrients.

Even though it might appear straightforward, there’s more to it than merely cutting those leaves off. To keep your plant healthy, you must assess how much of the leaf is dying and then carefully remove the damaged areas.

How are brown spots handled?


  • Medications. Applying retinoids (tretinoin) and a moderate steroid along with prescription bleaching creams (hydroquinone) may cause the spots to progressively vanish over several months.
  • strong pulsed light and laser.
  • Freezing (cryotherapy).
  • Dermabrasion.
  • Microdermabrasion.
  • Peeling agent.

How can leaf spots be treated naturally?

Blend everything in a gallon of water. Every ten days, spray the entire garden. When used on tomatoes and squash, this works incredibly well.

It may be possible to prevent blight by preventing leaves from coming into touch with the soil. Around tomatoes, using mulch or landscaping cloth can significantly lower the occurrence of blight.

Powdery Mildew Remedy

  • a quart of water
  • 2 tablespoons of baking soda/epsom salts or 1 splash of rubbing alcohol

Important: As you move from plant to plant, immerse pruning and gardening tools in a solution of 1 part bleach to 10 parts water to help prevent the spread of illness. With your hands, you can remove yellowed or discolored leaves, but wash your hands afterwards.

How do you know when to water an anthurium?

Slow-growing anthurium plants produce odd-looking, vibrant flowers and flat, spade-shaped leaves. The spathe, which is essentially a single leaf that ranges in color from milk white to deep burgundy, is the component of the flower that attracts the most attention. The spadix, a tall, slender spike of various colors that rises above the spathe, is the actual flower.

Watering anthuriums is simple, despite seeming counter-intuitive at first. Although they are tropical plants that prefer high humidity levels, anthuriums have extremely minimal water needs. Anthuriums really only need to be watered once every other week or so because of their large, meaty roots, which decay readily in damp soil.

If you let the soil dry out significantly beforehand, you’ll be able to tell when to water an anthurium. Give the dirt a good watering until it seems dry to the touch, then leave it alone till it dries out once more.

Anthurium: Does it require sunlight?

Anthuriums are known for their enduring, heart-shaped blooms. The colorful, magnificent blossoms add a wonderful pop of color to the house and are quite simple to maintain!

If you have bright shade, anthuriums are a fantastic option for an outdoor summer container as they thrive in the heat and humidity and should bloom all season.


Anthuriums will grow and survive in low light, but they won’t blossom because they need medium to bright light to bloom. Select a location that receives some sunshine but is not directly in the sun (early morning or late afternoon sun is generally OK).


Keep the soil barely damp but not drenched. In the spring and summer, the plant will require extra water, especially if it is in direct sunlight. Root disease may result from overwatering and be challenging to treat.

Use any all-purpose fertilizer ideal for indoor plants to fertilize in the spring and summer. You can achieve excellent results by fertilizing at a diluted rate (often 1/4 strength) with each watering, and you won’t need to keep track of when you last fertilized. It also works well to use a slow-release fertilizer like Osmocote.

Heat Index and Humidity:

Regular home temperatures are excellent, but like many tropical houseplants, summertime outdoors brings additional heat and humidity that feels “exactly like home.” If you decide to grow your Anthurium outdoors, just be sure to keep it away of direct sunlight.

Do not place your Anthurium too close to a heat source or in a hot or cold draft. This may cause the leaves to dry out and develop brown tips.


Repot your Anthurium in the spring when the roots are starting to grow if it is outgrowing its container. Any high-quality, well-drained soil mixture will do.

Anthuriums develop an extended stem with exposed root nubs as they get older. These stems can be wrapped in wet sphagnum moss, tied, and covered with a thin piece of plastic to keep the moisture in. The roots should start to develop into the moss if you keep it moist. Once a significant number of new roots have grown, the stem can be severed at the soil line and the newly developed roots potted.

Anthuriums should continue to bloom for nearly the entire year as long as they receive enough light, moisture, and fertilizer during active growth. If your Anthurium isn’t blossoming, it’s probably due to a lack of moisture or light.

How can I determine the health of my anthurium?

Your anthurium’s bottom leaves occasionally lose their bright green hue and develop brown tips. If you are certain that your plant is receiving enough light and that you are not overwatering it, too much fertilizer may be the cause of its problems.

When should I fertilize my Anthurium Plant?

Only fertilise your anthurium plant when it is actively developing. This indicates that during the spring and summer, roughly every four to six weeks.

What is the best fertilizer for Anthurium Plants?

Phosphorous-rich fertilizers work well for anthurium plants. Look for a blend like 10-30-30 that has a higher “P to “N and “K ratio. Before usage, dilute any fertilizer to about a quarter strength.

Is Miracle Grow good for Anthurium Plants?

You can feed your anthurium plants Miracle Grow. Select a more phosphorous-rich recipe and diluted to roughly one-fourth strength.

Are used coffee grounds good for Anthurium Plants?

For Anthurium plants, used coffee grounds are not the greatest option. A phosphorous-rich fertilizer that is heavily diluted is a better choice.

Supply your anthurium with extra light.

Anthuriums thrive in indirect or moderate light. After all, they originated from forests where they flourished under the shade of big plants and tree canopies. Having said that, your anthurium may have more inflorescences the more intense indirect light you can provide. Additionally, light will assist in your spathes changing color and not going back to green. Consider providing your plants with additional light during the day by using a grow light if the amount of natural light in your home is insufficient.

Fertilize your anthurium.

So which fertilizer is ideal for your anthurium? Throughout the growing season, anthuriums love receiving nutrients from a balanced fertilizer on a monthly or bimonthly basis. But if flowering is your ultimate goal, spend money on a bloom booster mix with a high phosphorus concentration (you might find it marketed towards orchids). To enrich your soil, you might also add organic items like kelp and worm castings.

And speaking of soil, you’ll want a mixture that drains somewhat well: Perlite, peat moss, and orchid bark should all be used in equal amounts. Because anthuriums are epiphytic, plants may grow on rocks and tree trunks without soil because their roots are air-dried in their native environment. Make sure your potting mix is well-draining and well-aerated if you’re growing your plant in one.

Give your anthurium more humidity.

Since anthuriums have been extensively hybridized and mass-produced, it’s likely that the one you buy at the grocery store won’t require much humidity to live. The most of the time, your plant should be alright as long as you don’t leave it beside a drafty window or air conditioner. However, humidity can promote blossoming and a lovely glossy finish, and flowers thrive in an environment with a humidity level of 70 to 80 percent. Naturally, having your plant next to a humidifier is the simplest approach to provide it with humidity. To increase humidity, you might leave your plant on a tray of moist pebbles or group it with other plants. Give your plant enough air circulation when you raise the humidity to stave off pest and fungus problems.

You won’t need to worry if you’ve ever wondered how to keep those lovely flowers on your grocery store anthurium. Though they may have a reputation for being picky, these plants are tougher than you may imagine. You’ll be creating the best environment for those wonderful flowers to bloom with an increase in light, fertilizer, and humidity.
