Improper Watering
Both overwatering and underwatering can make Sago palm turn yellow. Sago palms prefer well-draining soil and should be watered only when the top inch of soil is dry. Overwatering can cause root rot and prevent the plant from absorbing nutrients. On the other hand, underwatering can stress the plant, leading to yellow leaves as it conserves energy.

Step 2. Check for Nutrient Deficiencies
Sago palms benefit from a balanced fertilizer, especially one with micronutrients like magnesium. If you find yellowing leaves on older ones, it may indicate nitrogen deficiency. If there are yellowing Sago palm leaves between the leaf veins, there might be a magnesium deficiency.
An ideal Sago palm fertilizer is one that is slow-release and specially formulated for palms. Typically, it contains a balanced ratio of nitrogen, phosphorus, and potassium, such as a 10-10-10 or 8-2-10 mix. Additionally, it should include essential micronutrients like magnesium, manganese, and iron, which are crucial for the health of these plants.
Step 3. Assess the Watering Routine
It’s essential to adjust the watering routine when you find Sago palm turning yellow. First of all, insert your finger about two inches into the soil to check its moisture. If it feels dry, you need to water it. Ensure you water deeply but infrequently and allow excess water to drain out of the pot’s bottom. This will help prevent root rot. On the contrary, if the soil is wet, reduce the frequency of watering and allow the soil to dry out between waterings.
Step 4. Evaluate Lighting Conditions
Sago palms thrive in bright, indirect light. If the Palm tree receives too much direct sunlight or too little light, Sago palm leaves may turn yellow. In this situation, you can adjust it to a south- or west-facing window or leave it under LED grow lights.

How to Care for a Sago Palm Plant?
To care for a sago palm, make sure it receives bright, indirect light, ideally from an east or west-facing window, while avoiding harsh direct sunlight that can scorch its leaves. Water the plant only when the top 75% of the soil is dry, as sago palms are drought-tolerant and susceptible to root rot from overwatering; make sure excess water drains out completely.
Use a well-draining soil mix, such as one containing sand and perlite, and choose a pot with drainage holes to prevent soggy conditions. Fertilize with a slow-release Sagp palm fertilizer during the Spring and Autumn to promote healthy growth, and maintain indoor temperatures between 65°F and 80°F (18°C to 27°C) to protect it from cold drafts and frost. Regularly prune yellowing fronds to keep the plant tidy, but be cautious as all parts of the sago palm are toxic if ingested.
