Monstera yellow leaves

Monstera plants have become a popular choice among plant enthusiasts, thanks to their stunning foliage and easy care requirements. However, like any living thing, Monstera plants can experience a range of issues. In this guide, we'll explore some common Monstera plant problems and offer solutions to help you keep your Monstera looking its best.

Yellow Leaves on Monstera Plants

One issue Monstera owners often face is yellow leaves. It's disheartening to see these vibrant green leaves turn an unhealthy shade of yellow, but don't worry – we're here to help. There are several possible causes for yellow leaves, including overwatering, underwatering, and nutrient deficiency.

Diagnosing Yellow Leaves

To determine the cause of yellowing leaves, start by assessing your plant's care routine. If the soil feels wet and soggy, overwatering might be the culprit. On the other hand, if the soil is bone dry, underwatering may be to blame. Lastly, consider whether your plant has received any fertilizer recently – nutrient deficiency can also cause yellow leaves.

Solutions for Yellow Leaves

Depending on the cause, you'll need to adjust your care routine to address the issue:

  1. Overwatering: Allow the soil to dry out more between waterings. It's better to water thoroughly but less frequently.
  2. Underwatering: Increase the frequency of watering to ensure the plant receives enough moisture.
  3. Nutrient deficiency: Apply a balanced, slow-release fertilizer to provide essential nutrients.

Curling Leaves on Monstera Plants

Curling leaves are another issue that Monstera enthusiasts might encounter. Curling can be caused by low humidity, underwatering, or pests.

Diagnosing Curling Leaves

To figure out the reason behind the curling, inspect the plant and its environment:

  1. Low humidity: Check the humidity levels around your Monstera. These plants prefer high humidity, ideally around 60%.
  2. Underwatering: Dry soil can lead to curling leaves. Make sure your watering routine is sufficient.
  3. Pests: Inspect your plant for any signs of pests, such as spider mites or mealybugs.

Solutions for Curling Leaves

Once you've identified the cause, you can take action to solve the problem:

  1. Low humidity: Increase humidity by placing a tray of water near the plant, using a humidifier, or misting the leaves regularly.
  2. Underwatering: Adjust your watering schedule to provide adequate moisture.
  3. Pests: Treat any infestations with appropriate pest control methods, such as neem oil or insecticidal soap.

Brown Spots on Monstera Leaves

Brown spots on Monstera leaves can be concerning, but they're often easy to fix. Causes of brown spots include sunburn, root rot, and bacterial or fungal infections.

Diagnosing Brown Spots

To determine the cause of brown spots, consider these factors:

  1. Sunburn: Monstera plants can get sunburnt if exposed to direct sunlight for too long. Check the plant's position and light exposure.
  2. Root rot: Overwatering can cause root rot, leading to brown spots. Inspect the roots for signs of rot.
  3. Infections: Bacterial or fungal infections can cause brown spots. Look for other signs of infection, such as a foul smell or slimy residue.

Solutions for Brown Spots

Once you've identified the cause, take steps to address the issue:

  1. Sunburn: Move your Monstera to a spot with bright, indirect light to prevent further sunburn.
  2. Root rot: Improve soil drainage and avoid overwatering. In severe cases, trim away affected roots and repot the plant in fresh soil.
  3. Infections: Treat any infections with a suitable fungicide or bactericide and remove affected leaves to prevent the spread of the disease.

Leggy Monstera Plants

A leggy Monstera plant can be a sign of insufficient light or over-fertilization. This issue can result in a less attractive appearance and weaker growth.

Diagnosing Leggy Growth

To identify the cause of leggy growth, consider the following:

  1. Insufficient light: Monstera plants need bright, indirect light to thrive. A lack of light can cause leggy growth and smaller leaves.
  2. Over-fertilization: Over-fertilizing can cause excessive, weak growth, making the plant appear leggy.

Solutions for Leggy Growth

To resolve leggy growth, take these steps:

  1. Provide more indirect sunlight: Move your Monstera to a brighter location with indirect light.
  2. Reduce fertilizer application: Cut back on fertilizer use and follow the recommended application rates.

Monstera Pests and How to Deal with Them

Pests can be a nuisance for Monstera plants, but with proper care and vigilance, you can keep them at bay. Some common Monstera pests include spider mites, mealybugs, and scale insects.

Identifying Pest Infestations

Regularly inspect your Monstera for signs of pests. Watch for webbing, small insects, or a sticky residue on leaves and stems.

Solutions for Pest Control

Once you've identified the infestation, take the following steps:

  1. Isolate the affected plant: Keep the infested plant away from other plants to prevent the spread of pests.
  2. Use natural remedies or insecticides: Treat the infestation with neem oil, insecticidal soap, or other appropriate treatments.
  3. Prevent future infestations with proper care: Maintain a clean and healthy environment for your Monstera, and regularly check for signs of pests.

Preventive Measures for Monstera Plant Problems

By taking a proactive approach to Monstera care, you can prevent many common problems before they arise. Here are some preventive measures to consider:

  • Proper watering techniques: Use the soak and dry method, allowing the soil to dry out between waterings.
  • Maintaining appropriate light and humidity levels: Provide bright, indirect light and maintain a humidity level of around 60%.
  • Regularly inspecting plants for signs of pests or disease: Catching issues early can make treatment easier and more effective.
  • Following a balanced fertilization schedule: Use a slow-release fertilizer to supply essential nutrients without causing excessive growth.


Monstera plants are stunning additions to any home, but they can experience various issues, such as yellow leaves, curling, and more. By understanding the causes of these problems and taking appropriate action, you can ensure your Monstera thrives for years to come. Keep learning and growing in your plant care journey, and remember that a little knowledge goes a long way in keeping your plants healthy and happy.
