Common Causes of Sago Palm Leaves Turning Yellow

Overwatering

One of the most common causes of sago palm leaves turning yellow is overwatering. Sago palms prefer well-draining soil and do not like to sit in water for extended periods. When the plant is overwatered, it can lead to root rot, which can cause the leaves to turn yellow and eventually die. To prevent overwatering, make sure to allow the soil to dry out between watering and avoid leaving the plant sitting in a saucer of water.

Underwatering

On the flip side, underwatering can also cause sago palm leaves to turn yellow. If the plant is not receiving enough water, it can cause stress to the plant, leading to yellowing of the leaves. To prevent underwatering, make sure to water the plant regularly, especially during hot summer months.

Nutrient Deficiency

Another reason why sago palm leaves may turn yellow is due to nutrient deficiency. Sago palms require certain nutrients such as magnesium, iron, and potassium to remain healthy. If the plant is not receiving enough of these nutrients, it can cause yellowing of the leaves. To prevent nutrient deficiency, make sure to fertilize the plant regularly with a balanced fertilizer.

Pests and Diseases

Sago palms can also be susceptible to pests and diseases, which can cause the leaves to turn yellow. Some common pests that can affect sago palms include mealybugs and scale insects. These pests can suck the sap out of the plant, causing it to weaken and eventually die. Diseases such as fusarium wilt and phytophthora can also cause yellowing of the leaves. To prevent pest and disease issues, make sure to inspect your plant regularly for signs of infestation and treat promptly with insecticides or fungicides.

Watering

To treat overwatering or underwatering issues, it is important to adjust your watering habits accordingly.
