Why Is My Anthurium Flower Turning Brown? Causes & Solutions

By | Updated April 22, 2023

Anthurium flowers can turn brown due to natural aging or various reasons such as overwatering, underwatering, incorrect lighting, and low humidity. Allow the soil to dry out between waterings and provide indirect light to prevent browning.

Anthurium flowers, with their vibrant and exotic appearance, can add a touch of tropical beauty to any indoor space. 

However, it’s not uncommon for plant enthusiasts to encounter the frustrating issue of browning flowers or leaves – leaving them wondering: why is my anthurium flower turning brown? 

In this article, we will discuss common causes and practical solutions to help revive your precious flamingo flower back into its full glory.

What Causes Brown Anthurium Flowers

Brown anthurium flowers can be caused by several factors affecting plant growth and health. 

These include inadequate watering, too much watering, direct sunlight exposure, low humidity levels, and pest infestations. 

Identifying the cause of brown flowers is crucial to maintaining the plant’s health and taking appropriate corrective measures.

Lack Of Water

Underwatering is one of the primary reasons why anthurium flowers begin to turn brown. 

When anthurium plants don’t receive sufficient hydration, they become stressed and struggle to maintain their vibrant appearance. 

An inadequate water supply can cause flowers and leaves to develop patchy brown spots, eventually leading them to wither and die. 

Plant enthusiasts need to balance keeping the soil moist but not overly saturated to sustain the plant’s health.


Overwatering is a prevalent issue among plant enthusiasts, causing various problems, including why your anthurium flower may turn brown. 

When Anthurium plants receive too much water, the roots become soggy and unable to breathe correctly. 

This lack of oxygen leads to root rot, which can cause the entire plant to suffer. 

Furthermore, over-hydrating your flamingo flower might not only result in turning its leaves brown but also in making them turn yellow.

It’s crucial to understand that each Anthurium species has unique watering needs; for instance, the Anthurium andraeanum requires well-drained soil with consistent moisture levels. 

Overwatered plants may exhibit symptoms such as wilting despite having damp soil or developing brown spots on their leaves due to fungal infections facilitated by excess water. 

To find the appropriate balance for your particular anthurium plant, try adjusting your watering schedule based on factors like temperature and humidity levels in your environment.

To identify if overwatering is causing browning issues in your anthurium houseplant’s flowers and foliage, inspect the roots. 

Healthy roots should appear firm and white, while unhealthy ones will seem mushy and blackened due to root rot caused by overhydration.

Furthermore, you can check whether the potting soil retains too much moisture by sniffing it – healthy soil should have a fresh smell instead of musty or rotten smelling.

Exposure To Direct Sunlight

Exposure to direct sunlight is a leading cause of anthurium flowers turning brown. 

Although these tropical plants may seem like they would naturally thrive in bright and sunny environments, the reality is that their native habitat consists of dappled shade beneath larger trees. 

When placed in direct sunlight for prolonged periods, especially during peak hours when the sun’s rays are strongest, your Anthurium plant can quickly suffer from too much heat.

Direct sunlight damage often presents as brown leaves, brown spots, and even browning of the entire flamingo flower itself. 

The intense heat from the sun essentially scorches and damages parts of this delicate plant. 

For example, you may notice your Anthurium leaves turning yellow before developing crispy brown edges or large patches on their surface. 

This affects the appearance of your beloved houseplant and weakens its ability to produce healthy new growth.

Low Humidity

Low humidity is a common cause of brown leaves and flowers in Anthurium plants. 

These tropical plants require a high level of humidity to thrive, and when the air is too dry, their leaves may turn brown or even curl up.

This can happen if you live in a dry climate or if you have an indoor heating system that dries out the air.

Pests And Diseases

Anthuriums, like any other plants, are susceptible to pests and diseases that can cause their flowers to turn brown. 

Mealybugs are one common pest that can affect Anthuriums. 

These tiny insects feed on the plant’s sap, which can lead to wilting and browning of its flowers. 

Other bacterial and fungal diseases, such as bacterial blight and wilt, root rot, and black nose disease, can also cause brown spots on anthurium leaves.

It is crucial to identify these problems early so you can take action before they worsen. 

You should inspect your Anthurium regularly for signs of infestation or infection by checking underneath the leaves or at the base of your plant. If you spot any issues, isolate the infected plant from others immediately to prevent the spreading of disease or pests.

Solutions For Brown Anthurium Flowers

Maintaining healthy Anthurium plants requires proper care and attention. 

Brown Anthurium flowers can be prevented by implementing effective watering techniques, providing bright indirect light, controlling humidity levels through misting or humidifiers, and utilizing natural remedies or pesticides to combat pests and diseases. 

Additionally, pruning techniques, such as removing brown leaves, can help promote plant health.

Proper Watering Techniques

Proper watering techniques are essential for preventing brown Anthurium flowers and ensuring the overall health of your plant. 

Here are some tips to keep in mind:

  1. Watering Frequency: Anthuriums prefer consistently moist soil but should not be overwatered. Wait for the top half-inch of the soil to dry out before watering again.
  2. Proper Drainage: Ensure that your pot has enough drainage holes, so water can escape and prevent root rot.
  3. Water Temperature: Anthuriums do well when their water is at room temperature or slightly lukewarm.
  4. Water Source: Use distilled, filtered, or rainwater, as tap water may contain harmful minerals and chemicals that can damage the plant.
  5. Soil Type: Use a well-draining, aerated soil mix specifically designed for tropical plants like anthuriums.

Proper Placement

The proper placement is crucial for preventing brown Anthurium flowers. 

These tropical plants thrive in bright, indirect light and should be kept from direct sunlight. 

Placing them near a south-facing window may cause their leaves to burn and turn brown. 

Instead, try placing your Anthurium plant in a spot with filtered sunlight.

In addition to avoiding direct sunlight, it’s also important to consider the humidity levels in your home when choosing where to place your Anthurium plant. 

Low humidity can cause brown spots on the flowers and leaves and prevent the healthy growth of new ones. 

Placing your plant in a bathroom or kitchen can help increase humidity levels, as these areas are more humid than other parts of the house.

Humidity Control

Proper humidity control is crucial in preventing brown Anthurium flowers. 

Here are some tips for maintaining the right level of humidity for your Anthurium plant:

  1. Use a humidifier: A humidifier can be an excellent investment to maintain the proper humidity levels in your home or office. It will help to increase moisture levels in the air and prevent your Anthurium plant from drying out.
  2. Group your plants together: Grouping them together can create a microclimate, increasing humidity around them.
  3. Add a pebble tray: Placing a tray of pebbles filled with water underneath the pot can also help to increase humidity levels.
  4. Use a misting bottle: Mist the leaves of your Anthurium plant regularly to keep them moist and prevent dehydration.
  5. Keep your Anthurium away from overly dry areas: Avoid placing your plant near air conditioning vents or heaters. These appliances can remove moisture from the air and cause your plant to dry out.

Pest And Disease Control

Keeping your Anthurium plant pest and disease-free is crucial in maintaining its health and beauty. 

Here are some ways to control pests and diseases:

  1. Monitor your plant regularly for any signs of infestation or damage. Look for bugs or spots on the leaves and stems.
  2. Use insecticidal soap or neem oil to eliminate common pests like spider mites, mealybugs, and aphids.
  3. Keep your plant clean by wiping down the leaves with a damp cloth to remove dust and debris that can attract pests.
  4. If you notice any brown spots or discoloration on the leaves, it may be a sign of bacterial blight or fungal diseases. Remove the infected parts of the plant immediately to prevent the spread of the disease.
  5. Provide proper ventilation and avoid overcrowding your plants to minimize the risk of fungal diseases such as leaf spot.
  6. Always use fresh soil when repotting your Anthurium plant to avoid introducing pathogens into the new soil.

Pruning Techniques

Pruning is essential in caring for Anthurium plants as it helps keep them healthy and promotes new growth. 

Here are some pruning techniques to consider:

  1. Begin by removing any yellow, brown, or wilted leaves. These leaves will not recover, and they can attract pests or diseases.
  2. Use sharp, sterile scissors or pruning shears to make clean cuts at a 45-degree angle.
  3. Cut off dead or decaying stems or flowers, which can also attract pests or diseases.
  4. If the plant has multiple stems, prune back the weaker ones to allow more energy to go into the stronger stems.
  5. As the plant grows taller, consider cutting back the top stems to promote lower growth and get a bushier plant.
  6. Be careful not to trim too much of the plant at once, as it can put undue stress on the Anthurium.

Remember that pruning should be done regularly but gradually over time to give your Anthurium time to adjust and grow healthy.

Final Thoughts

Brown anthurium flowers can be caused by various factors such as lack of water, overwatering, exposure to direct sunlight, low humidity, and pests and diseases. 

However, you can revive your beloved plant to its former glory with proper care and attention.
