Pink Rot


This disease is named for the pink fungal spores that grow on the trunk of affected palms. The fungus typically only affects palms that are already weakened due to insect infestations, diseases, or overwatering.


Pink Rot is most prevalent during winter and spring. You can find it at the base of the trunk and on newly emerged fronds. Pink rot will cause brown and black spots to appear on all surfaces of your palm, as well as pink fungal spores. You will also see any new growth is stunted and distorted.

How to Treat

  1. Prevention – This disease typically only affects palms that are infested with insects or chronically overwatered. The best defense is removing leaves and husk to promote proper light and airflow. Ask your nursery professional for proper watering and fertilizing guidelines and treat your palms with a systemic insecticide at the onset of growing season to minimize the risk of infection.
  2. Fertilizer – Palms love soils that are high in micronutrients! Give your palms the nutrients they need with regular applications of Moon Microboost and Palm Juice. These blends are specifically formulated with micronutrients such as manganese, iron, zinc, boron, and more to keep them green and glowing all year round.
  3. Treatment – Roots should never be left in standing water—especially not on palm species. Start by improving soil drainage with routine applications of Landscape Soil & Water Conditioner. Use systemic fungicide and mix with water and apply to the soil using the bucket. Use copper fungicide and apply to foliage using hose end sprayer.
