Sago Palm Turning Yellow

Why Is My Sago Palm Turning Yellow? Quick Solutions

Many sago palm owners may experience their beloved plant’s leaves turning yellow and wonder what could be causing this issue. It’s crucial to recognize the possible reasons behind this color change to effectively remedy the problem and maintain the Sago palm’s health.

A few common reasons for a sago palm turning yellow include moisture stress, mineral deficiency, sunburn, excessive fertilization, cold damage, transplant shock, and pests. These factors can often be addressed with proper intervention and care techniques to restore the sago palm’s vibrant green foliage.

Understanding the specific cause of yellowing leaves in a sago palm helps ensure the most targeted and effective solution, allowing the plant to thrive and remain a beautiful addition to any landscape or indoor space.

Common Causes of Yellowing Leaves in Sago Palm

Watering Issues

One of the most common reasons for a sago palm turning yellow is moisture stress, which can be a result of either under-watering or over-watering the plant. Maintaining a proper balance of water is crucial to its health and prevent the death of your sago palm.

Fertilizer Problems

Improper fertilization can also cause yellowing in sago palms. Nutrient deficiencies, such as a lack of nitrogen, potassium, or magnesium, lead to discoloration in the leaves of the plant. Closely monitor and address these deficiencies if yellowing continues despite proper watering practices.

On the other hand, excessive fertilization can also cause problems for sago palms. An overabundance of nutrients may lead to imbalances and even toxicity, negatively affecting plant health.

Disease and Pests

Plant diseases and pests can contribute to yellowing in sago palms. Insects like scale insects and mealybugs can cause damage, weakening the plant and resulting in yellow leaves. Keeping a watchful eye for any signs of infestation is crucial for maintaining the health of your sago palm.

Diseases affecting the root system, such as root rot, can also cause yellowing in sago palms. Root rot typically occurs in waterlogged soil or overly moist conditions.


Improper watering and fertilization, pests, and disease can cause a sago palm to turn yellow. Nutrient deficiencies or excess fertilizer, scale insects, mealybugs, and root rot are common causes. To ensure proper growth, closely monitor watering and nutrient levels, as well as pest and disease control.

Environmental Factors for Yellowing Leaves in Sago Palm

Light Conditions

Sago palms require adequate sunlight to maintain their health and vibrant color. Insufficient light can cause the fronds to turn yellow. It is essential to provide your sago palm with bright, indirect sunlight for optimal growth. Place the plant near a window that receives ample sunlight or in a well-lit outdoor area. However, avoid exposing the plant to direct sunlight for extended periods, as it can cause sunburn and further yellowing of the leaves.


Cold weather can have a negative impact on sago palms, leading to the yellowing of leaves. Sago palms are sensitive to temperature changes, and their roots’ nutrient uptake can be affected when the temperature drops. Ensure your sago palm is placed in an area with stable temperatures, ideally between 65°F and 75°F. If your plant is located outside, consider moving it indoors during colder seasons or add insulation to protect its roots.


While sago palms can tolerate a wide range of humidity levels, they prefer moderate humidity for optimal growth. Too low or too high humidity levels can stress the plant and cause the fronds to turn yellow. To maintain suitable humidity levels, avoid placing the sago palm near heating or air conditioning vents, which can cause fluctuations in humidity. If necessary, use a humidifier or a tray filled with water and pebbles to increase humidity levels around your plant.


Sago palms require bright, indirect sunlight, stable temperatures between 65°F and 75°F, and moderate humidity to prevent the fronds from turning yellow. Direct sunlight, cold weather, and humidity fluctuations can cause yellowing. It is recommended to place the plant near a well-lit window or in a well-lit outdoor area and avoid exposing it to heating or air conditioning vents.

Preventive Measures

Preventing yellowing of sago palm leaves involves several practices that ensure the plant’s overall health. These include proper watering techniques, choosing the right fertilizer, and pest and disease control.

Proper Watering Techniques

One common reason for sago palms turning yellow is moisture stress, which can be due to both underwatering and overwatering. To prevent this, ensure the soil remains consistently moist but not soggy. Water the plant deeply and allow the top two inches of the soil to dry out before watering again. It is essential not to let the sago palm sit in waterlogged soil or allow it to be completely dried out for an extended period.

Choosing the Right Fertilizer

Nitrogen, magnesium, and potassium deficiencies can cause yellowing in sago palms. Fertilize the plant once in the spring and once in the summer with a general-purpose fertilizer to avoid these deficiencies. Be cautious not to use too much fertilizer, as it can also cause yellowing leaves. Following the manufacturer’s instructions on the fertilizer package and observing the plant’s response will help in choosing the right fertilizer and quantity for the sago palm.

Pest and Disease Control

Regularly inspect the sago palm for signs of pests or diseases, as these can also lead to yellowing leaves. Remove any infected parts of the plant and treat it with appropriate insecticides or fungicides when needed. Maintaining proper watering and fertilizing practices, as mentioned earlier, can also help in preventing pest infestations and diseases. Monitor the plant’s health and address any issues promptly to avoid extensive damage to the sago palm.


To prevent yellowing of sago palm leaves, proper watering, fertilization, and pest and disease control are essential. Avoid moisture stress by watering the plant deeply and allowing the soil to dry out slightly before watering again. Choose the right fertilizer and avoid using too much. Regularly inspect the plant for pests and diseases and address issues promptly to maintain the plant’s health.

Reviving a Yellow Sago Palm

Identifying the cause of yellowing in sago palms is crucial for implementing the right solution. Common reasons for yellowing include moisture stress, nutrient deficiencies, cold damage, and acidic soil.

Begin by addressing moisture issues. Ensure that the soil drains well and that the palm receives adequate watering—neither underwatering nor overwatering. Adjust the watering schedule as needed to maintain consistent moisture

If nutrient deficiency is the cause, incorporating a slow-release fertilizer with balanced ratios of nitrogen, phosphorus, and potassium can help address the issue. It’s also essential to monitor the soil pH levels to ensure the plant can absorb these nutrients effectively. For cold damage prevention, take steps to insulate the sago palm during winter months, such as using a plant blanket, straw, or mulch. This will help protect the roots from freezing temperatures.

In the case of transplant shock or root rot, a yellow sago palm may require repotting into fresh soil with better drainage. Create additional drainage holes if necessary, but avoid removing yellowing leaves as they can still photosynthesize and support the plant’s recovery. Regularly examining the sago palm for pests and promptly addressing any infestations can also prevent yellowing caused by insect damage.


This article discusses how to revive a yellow sago palm, with tips on identifying the cause of yellowing and implementing solutions. The article suggests addressing moisture issues, nutrient deficiencies, cold damage, and acidic soil, as well as repotting into fresh soil with better drainage and monitoring for pests.


Will my sago palm turn green again?

If your sago palm has turned yellow or brown, it may not turn green again. The yellow or brown color may be an indication of stress, disease, or environmental factors such as overwatering, underwatering, or exposure to cold temperatures.

However, if only a few fronds have turned yellow or brown and the rest of the plant still looks healthy, you can remove the damaged fronds and take steps to improve the plant’s care, such as adjusting the watering schedule, providing proper fertilization, and ensuring it is getting enough light.

It is important to note that sago palms grow very slowly and it may take some time for the plant to recover and produce new growth. Patience and consistent care are key to helping your sago palm thrive.
