A Key to Common Landscape Palm Disorders and Diseases in the Continental United States
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.”
The key is divided into five major headings based on location of observed symptoms:
1) entire canopy (most or all leaves)
2) oldest leaves only
3) youngest leaves only
4) flowers and fruits
5) trunk.
