Palm Tree Nutritional Deficiencies and Diseases

Most of us from up north love the tropical atmosphere created with palms in our yard or on our patio.  But palm trees require special care.

see Care and Maintenance of Landscape Palms in South Florida, by Worden, Broschat, and Yurgalevitch, June 2002.


Nutritional Deficiencies

Palms require extra amounts of Potassium (K), the third number on fertilzer bags.  They also need the micro nutient elements of Manganese (Mg), Magnesium (Mg), Iron (Fe), and Boron (B).  Rarely is the lack of Nitrogen (N) an issue with yellowing or deformed leaves. Though it may improve your gas mileage.

See Palm Tree Pictures for examples of what sick and recovered palm trees look like.  Many pictures from University of Florida IFAS records.
