Why Is My Palm Tree Yellowing?

Yellowing palm trees may be caused by natural aging, pest infestations, nutrient deficiencies, and even environmental factors like excessive heat or cold. Identifying the root cause of yellowing is crucial because it can indicate what needs to be done to save your palm plant from further damage or death.

What Causes Palm Tree Leaves To Turn Yellow?

Several factors can cause palm tree leaves to turn yellow, including:

Nutrient deficiencies

Yellowing leaves in popular indoor palm trees, such as ponytail palms, areca palms, majesty palms and queen palms, can be caused by nutrient deficiencies of magnesium, nitrogen, and potassium. Inadequate nutrition can prevent the growth of new leaves and lead to yellowing of existing ones.

Common palm diseases like ganoderma can cause brown leaves or yellow fronds.


Use a fertilizer specifically formulated for palm trees, as these contain the micronutrients palm trees need. Apply the fertilizer according to the instructions on the package, usually every three to four months.

Conduct a soil test to determine if the soil is suitable for palm trees. Palm trees prefer slightly acidic soil with a pH of around 6.0 to 6.5. If your soil is too alkaline, it can make it difficult for your palm tree to absorb nutrients. You can adjust the pH level of the soil using products available at garden centers.

Overwatering or underwatering

Too much or too little water can stress the palm tree and cause the yellowing of leaves and lead to nutrient deficiencies.


Palm houseplants enjoy a regular watering schedule, and are sensitive to inconsistencies in water amount and frequency.

Only water your palm tree when the top inch of soil is dry to the touch. Use a pot with drainage holes and a well-draining potting mix. Do not overwater or allow the plant to sit in water, as this can cause root rot or fungal infections which can lead to yellow leaves.

Improper watering or nutrient deficiencies can cause yellow fronds.

Pest infestations

Certain pests like spider mites, mealybugs, or scale insects can damage the leaves of a palm tree, leading to yellowing or browning.


Watch out for common palm tree pests and diseases such as fusarium wilt and leaf spot. If you notice any signs of infestation, take action to address the issue promptly. Different pests require different treatments, so identify the pest infesting your palm tree.

If you notice a pest infestation on your palm tree, isolate it from your other plants to prevent the infestation from spreading. Remove the affected palm fronds to prevent the infestation from spreading further.

Insecticidal soap is a natural and effective way to control pest infestations on indoor palm trees. Spray the soap on the leaves and stems of the plant, following the instructions on the label. Horticultural oil is another natural and effective way to control pest infestations on indoor palm trees. Apply the oil to the leaves and stems of the plant, following the instructions on the label.

Environmental factors

Extreme temperatures, exposure to direct sunlight, or fluctuating humidity levels can also cause palm tree leaves to turn yellow.


If your palm tree is exposed to direct sunlight, move it to a location with filtered or indirect sunlight. Avoid placing it near drafty windows or doors where it can be exposed to strong winds.

Palm trees prefer temperatures between 60°F to 80°F (15.5°C to 26.5°C). Avoid placing your palm tree in areas with extreme temperature changes, such as near heating or cooling vents.

Use a humidifier or place a tray of water near your palm tree to increase humidity.

Ponytail Palm
Indoor palms like bright, indirect light. Too much sun can cause yellow leaves.

Proper Drainage

Proper drainage is crucial for indoor palm trees. Dense, poor-draining soil can damage the root system, causing root rot and nutrient deficiencies.


Ensure that the pot has drainage holes to prevent water from accumulating at the bottom. Use a well-draining potting soil made for palm trees, or make your own by adding sand and perlite to potting mix.

Premade potting soils for palm trees have added nutrients to prevent potassium, nitrogen, and magnesium deficiency that palm trees are susceptible to.

Natural Aging

Like all living things, palm trees age and shed old leaves as part of their natural life cycle. As a result, the yellowing of lower leaves is a natural process in many palm species. If your indoor plant is approaching 10 years old and no longer producing new growth, it’s at the end of its lifespan.

Frequently Asked Questions

Can yellow palm leaves turn green again?

No. Once a leaf has turned yellow, it indicates it's dying and cannot be revived. However, by addressing the underlying issue that's causing the yellowing, you can prevent further yellowing and ensure that your palm tree produces healthy green leaves in the future.

Should I remove yellow palm leaves?

Yes, cut off yellow palm leaves to allow the plant to focus on healthy growth. Use clean pruning shears to cut the leaf as close to the trunk as possible without damaging the trunk or other leaves.

What fertilizer to use for yellowing palm trees?

To address yellowing palm trees due to nutrient deficiencies, a palm-specific fertilizer with balanced amounts of nitrogen, phosphorus, and potassium is recommended. Look for a slow-release fertilizer that can provide the plant with nutrients over a longer period of time. Many palm fertilizers also contain magnesium and manganese, which are important micronutrients for palm trees.

When using palm fertilizer, it's important to follow a regular fertilization schedule as directed on the package to prevent nutrient deficiencies. Over-fertilizing can lead to salt buildup in the soil, which can cause further damage to the palm tree.

What are some plant care tips for taking care of my palm tree?

Ensure that your palm tree receives enough water. Water the plant deeply and allow the soil to dry out slightly before watering again. Overwatering causes root rot, while underwatering can cause brown tips and yellowing of the leaves.

Regularly remove old fronds or older leaves to improve the appearance of your palm tree. Avoid pruning healthy fronds, which can stress the plant and reduce its green color.

Keep an eye on the new fronds of your palm tree, as they can provide an indication of its health. If the new fronds are growing well, it's a sign that your palm tree is healthy and thriving.
