A Key to Common Landscape Palm Disorders and Diseases in the Continental United States is available at the University of Florida Fort Lauderdale Research and Education Center website. Follow the link to find out how to read your palm’s problems.
To use this key effectively, you must :
a) know how the palm species looks normally (when it is healthy)
b) closely examine the entire palm from the top of the canopy to the soil line
c) note the portion of the palm that does not look “normal.”
