Palm Problems (or not)
Palms are unique plants and can present gardeners with questions about what’s happening to landscape palm. Palm problems may or may not be an actual problem.
For example, here is an example of the trunk of a mature palm. Is the bark splitting cause for worry?
Actually this is NOT a palm problem. As palms mature, they develop root-like structures that cause the bark to split. While it looks problematic, this abnormality is not a sign of failing health.
As palms age, their root zone extends above the soil line. This extra plant materials causes the “bark” to split. The extent of the flare varies by plant but many of our common landscape palms will do this.
Do not worry that this is a palm problem. Do not take other action to fix or repair this perceived damage. You may inadvertently cause damage that isn’t there.
However, palms are unique and often have confusing signs. For more information on some common palm abnormalities visit this UF publication, http://edis.ifas.ufl.edu/pdffiles/EP/EP34400.pdf
