Why Are My Pothos Leaves Turning Yellow? Common Causes & Solutions

When you notice your beloved Pothos plant’s leaves turning yellow, it can be alarming. After all, this plant is known for being low-maintenance and thriving in various conditions. But don’t panic just yet—pothos leaves turning yellow is a common issue that many plant owners face. There are several reasons why this might happen, and luckily, most of them are fixable. In this article, we will delve into the most common causes behind pothos leaves turning yellow, the potential solutions, and how you can ensure your Pothos thrives for years to come.

Understanding the Causes Behind Pothos Leaves Turning Yellow

Before you can fix the issue, it’s essential to understand why pothos leaves turning yellow occurs in the first place. There are several potential culprits, each requiring a different approach to solve.

Overwatering or Underwatering: The Most Common Culprit

One of the main reasons your pothos leaves may start turning yellow is improper watering. Yellowing leaves can result from both overwatering and underwatering, as these conditions stress the plant. If you’re overwatering, the roots of your Pothos may become waterlogged, leading to root rot. This prevents the roots from absorbing nutrients, which in turn causes the leaves to turn yellow.

On the other hand, if you’re underwatering your Pothos, the plant will become stressed and start showing signs of dehydration. The leaves may begin to yellow, dry out, and eventually fall off.

How to Fix It:

• Overwatering: Ensure the pot has good drainage and let the top inch of soil dry out before watering again.
• Underwatering: Water your Pothos thoroughly and consistently. Let the soil dry out between waterings, but never leave it too dry for too long.

Improper Lighting: Not Enough or Too Much Sunlight

Your Pothos plant may also suffer from yellowing leaves if it’s not getting the proper amount of light. Pothos leaves turning yellow in low light is a common problem. Pothos plants do best in bright, indirect light. Excessive direct sunlight can scorch the foliage, resulting in pothos leaves turning yellow and brown, while insufficient light can make the plant leggy and weak, eventually leading to yellowing leaves.

How to Fix It:

• Position your Pothos in an area with bright, indirect sunlight, and avoid direct sunlight to prevent leaf burn.
• If your space lacks natural light, consider investing in a grow light to give your Pothos the light it needs to thrive.

Nutrient Deficiencies: Yellowing Leaves Due to Lack of Essential Nutrients

Another common reason for pothos leaves turning yellow is a lack of essential nutrients, particularly nitrogen. Nitrogen is vital for healthy leaf growth, and without it, the leaves may start to yellow. Iron deficiencies are also a common culprit, especially in more acidic soils.

How to Fix It:

• Use a balanced, water-soluble fertilizer to supplement any missing nutrients. Fertilize the plant every 4–6 weeks during its active growing period.
• If you suspect an iron deficiency, consider using a fertilizer with chelated iron, which is easily absorbed by the plant.

Pests and Diseases: An Unseen Problem

Sometimes, the cause of pothos leaves turning yellow and curling or yellowing in patches is a pest infestation. Spider mites, aphids, or mealybugs can damage the leaves and cause them to turn yellow. Pests are more likely to infest a Pothos when it’s stressed from low water or humidity levels, as they thrive in dry conditions. Yellowing leaves may also indicate a fungal or bacterial infection.

How to Fix It:

• Regularly check your Pothos for pests by looking for tiny webs, sticky residue, or small insects on the leaves
• Use an organic insecticide like neem oil or a homemade solution (mix water and dish soap) to get rid of pests.
• Prune any heavily affected leaves to prevent the spread of infection or pests.

Temperature Stress: Cold Drafts or Heat Waves

Pothos plants are quite sensitive to temperature fluctuations. Pothos leaves yellowing in winter or exposure to cold drafts can cause the plant to stress and develop yellow leaves. Similarly, placing your Pothos near a heater or in a hot, dry environment can lead to dehydration, resulting in yellowing leaves.

How to Fix It:

• Keep your Pothos in a room with temperatures between 65°F and 85°F (18°C – 29°C).
• Avoid placing your plant near air conditioners, heaters, or windows where cold drafts may affect it.

How to Fix Pothos Leaves Turning Yellow: Practical Solutions

Now that we know the common causes of pothos leaves turning yellow, let’s explore how to fix it and get your plant back to its healthy, lush self.

Adjust Your Watering Routine

As mentioned, improper watering is a common reason for yellowing leaves. Here’s how you can fix it:

• Overwatering: If you suspect you’ve been overwatering, remove the plant from the pot and check the roots for rot. Trim any black, mushy roots, and repot the plant in fresh, well-draining soil. Allow the plant to dry out before watering again.
• Underwatering: If your plant is too dry, give it a good soak. Ensure the water drains through the bottom of the pot, and don’t let it sit in excess water. Going forward, water your Pothos when the top inch of soil feels dry to the touch.

Provide Proper Lighting

To prevent pothos leaves turning yellow in water or in low light, it’s essential to place your Pothos in the right spot.

• Ensure the plant gets bright, indirect sunlight. If you don’t have access to natural light, use a grow light to supplement.
• Keep your Pothos away from direct sunlight to prevent leaf scorching, which can cause the leaves to turn yellow and brown.

Fertilize Your Pothos

If your Pothos is showing signs of pothos leaves turning yellow and falling off, a nutrient deficiency might be to blame. Fertilizing your plant can help resolve the issue.

• Choose a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium for optimal growth.
• Fertilize your Pothos once a month during the growing season (spring and summer) and reduce the frequency during the fall and winter months.

Treat Pests and Diseases

If pests or diseases are causing pothos leaves turning yellow and brown, you’ll need to take immediate action.

• Inspect the plant regularly for pests such as spider mites, aphids, or mealybugs.
• Use neem oil or another natural pesticide to treat any infestations. Apply it to the affected areas and the entire plant, following the instructions on the product.

Maintain Proper Temperature and Humidity

To prevent pothos leaves turning yellow and drooping due to temperature stress, make sure your plant is kept in an environment with stable temperatures.

• Keep your Pothos away from air conditioners, heaters, and cold drafts.
• If your home is very dry, consider increasing humidity around your plant by placing a humidity tray beneath the pot or using a room humidifier.

Preventing Future Yellowing of Pothos Leaves

Now that you’ve taken care of the immediate causes of yellowing leaves, let’s talk about prevention. Regularly monitoring your plant’s health is crucial to prevent pothos leaves turning yellow from becoming a recurring problem.

Regular Care and Maintenance

• Water your Pothos when the top inch of soil feels dry to the touch.
• Regularly inspect your plant for pests and address any infestations immediately.
• Ensure your plant gets bright, indirect light.
• During the growing season, feed your plant with a balanced fertilizer.
