Sharing is caring!

If you’ve noticed your monstera plant’s leaves turning light green, there could be a variety of reasons behind this change. It’s essential to understand these factors to properly care for your beloved monstera and maintain its vibrant, healthy appearance.

Several common causes of light green monstera leaves include lack of sunlight, watering issues, nutrient deficiencies, and pest damage. Knowing the possible reasons, you will be better equipped to identify and address the underlying issue, helping your monstera thrive once again.

In this article, we’ll explore the different causes of light green monstera leaves and provide solutions for each problem, ensuring your plant receives the proper care and attention it deserves.

The Role of Chlorophyll in Monsteras

Chlorophyll plays a crucial role in the health and well-being of monstera plants. This green pigment is necessary for the process of photosynthesis, which involves converting light energy, water, and nutrients into food for the plant to grow and thrive.

When monstera plants receive an adequate amount of light, they can produce sufficient chlorophyll, giving the leaves a rich, dark green color. However, when they do not receive enough light or lack the necessary nutrients, such as nitrogen, chloroplasts can’t produce enough chlorophyll. This can cause the leaves to turn a lighter green color, slow down the plant’s growth, and reduce its overall leaf coverage.

In order to maintain a healthy monstera with vibrant, deep green leaves, it is important to provide the right balance of light and key nutrients, including nitrogen, phosphorus, and potassium. Ensuring optimal temperature and humidity levels can also contribute to proper chlorophyll production and overall plant health. Additionally, consider using plant food specifically designed for indoor plants to maintain a balanced nutrient intake.

Common Causes of Light Green Leaves

Insufficient Light Exposure

One possible cause of light green leaves on a Monstera plant is a lack of adequate light. Proper light exposure is crucial for photosynthesis, which helps the plant produce chlorophyll, resulting in a healthy dark green color. Make sure your Monstera is receiving sufficient indirect light for optimal growth.


Excessive watering can also lead to light green leaves in Monstera plants. Overwatering may cause the roots to become waterlogged, restricting their ability to access necessary nutrients for healthy growth. Ensure that your Monstera’s soil is well-draining and a consistent watering schedule is maintained.

Root Rot

Root rot can be another reason for light green leaves in Monstera plants. Caused by overwatering or poor drainage, root rot can damage the root system and limit nutrient absorption, affecting the overall health and color of the plant. Check your plant’s roots for signs of rot and address any issues promptly.

Nutrient Deficiencies

Nutrient deficiencies, particularly nitrogen, can lead to lighter green leaves in Monstera plants. Nitrogen plays a vital role in producing chlorophyll for healthy, dark green foliage. To remedy a deficiency, consider amending the soil with a balanced fertilizer to provide necessary nutrients for your plant’s growth and development.

How to Prevent Light Green Leaves in Monsteras

Proper Care Techniques

To maintain the desired dark green color of monstera leaves, it’s important to address the plant’s nutrient needs. Providing the right balance of nitrogen, phosphorus, and potassium in a liquid indoor plant food will help promote healthy chlorophyll production. Additionally, ensure the monstera receives sufficient calcium and magnesium which are essential for proper leaf development.

Balancing Light and Water Needs

Arrange your monstera in a position where it can receive at least 6 hours of indirect light each day, as proper lighting plays a crucial role in supporting chlorophyll production. Regular watering is also essential, so be sure to monitor the plant’s moisture needs and adjust accordingly. To further enhance the overall health of your monstera, apply a slow-release indoor plant fertilizer during both spring and fall.

Rehabilitating Your Monstera

Addressing Nutrient Needs

One possible reason for your monstera turning light green is due to nutrient deficiencies, particularly nitrogen. To address this issue, consider using a balanced fertilizer or a specially formulated monstera fertilizer. Apply it according to the manufacturer’s instructions, usually during the growing season, to provide the essential nutrients for healthier and darker green leaves.

Trimming Damaged Leaves

If your monstera exhibits pest damage or appears to have diseased leaves, it is crucial to trim these affected parts away. Carefully remove the damaged leaves by cutting close to the main stem, using clean and sharp gardening shears. Doing this not only improves the appearance of your monstera, but it also prevents the spread of pests or diseases and ensures that the plant can focus its energy on producing fresh, healthy growth.
