Our beautiful state of Florida is known for three main things: sunshine, the ocean, and palm trees. Palms are a staple here and one of the most common trees we have, and just like any other tree - and your lawn - they need to be fertilized to stay healthy and beautiful year-round. Now, you may be staring at your palm trees and wondering how often you should fertilize them, what nutrients are in palm tree fertilizer, whether you should use a fast-release or slow-release product, and how you should apply these treatments. While it may seem overwhelming, don't worry! These are some of the most frequently asked questions about palm tree fertilization, and we'll answer them in this blog so that you have a better understanding of this service.


How often should you fertilize your palm trees?

Regular fertilization treatments are crucial to maintaining healthy palm trees. Because of this, you should fertilize them four times throughout the year - in February, May, August, and November. Quarterly fertilization will provide a consistent supply of the nutrients your palms need to thrive.

Some common palm trees that you may have on your property include royal palms, Alexander palms, bottle palms, and canary date palms.


What nutrients are typically in palm tree fertilizer?

Similar to your lawn, fertilizer provides your palms with the nutrients they need to thrive, the most important ones being nitrogen, potassium, phosphorus, and magnesium. These essential nutrients each contribute to improving the health of your palm trees:

  • Nitrogen: Nitrogen aids in chlorophyll production, which helps your palms perform photosynthesis and produce rich green fronds.
  • Potassium: Potassium strengthens your palm trees to keep them healthy and more resistant to stressors, such as diseases and insect infestations.
  • Phosphorus: Phosphorus helps your palm trees develop and grow a strong, resilient root system.
  • Magnesium: Magnesium contributes to photosynthesis and will help your palm trees grow healthy, green foliage.

Should you use a fast-release or slow-release fertilizer for your palm trees?

A fast-release fertilizer is a liquid treatment that provides a quick supply of nutrients directly to the roots of your palm trees; a slow-release fertilizer is granular and provides a gradual, consistent supply of nutrients over time as it sinks into the surrounding soil. While both are beneficial, you should opt to use a slow-release fertilizer for your palm trees. A granular, slow-release fertilizer will ensure that your palms receive a constant supply of nutrients over an extended period of time.


How should you apply fertilizer to your palms?

When applying the granular fertilizer to your palms, you should distribute the product evenly under the dripline of the canopy; the dripline of your palm tree is the area under the furthest outward-reaching fronds that create the outer circumference of the canopy. The fertilizer should be at least 6 inches from the trunk of the palm tree so that when you water it, the nutrients seep underground to the roots below.
