There are a tremendous number of very informative websites on palm care. I've tried to select the ones that are focused on palms in South Florida. Some of the more exotic palms can be challenging at times. Having a small shade house might help until your wife hangs a "no palms allowed" sign on the entrance.

Florida has no "average" weather. It can be cold, wet and windy some days or hot, dry and windless other days. Many of the more uncommon small palms are from the understorey of rainforests or surrounding area and are accustomed to year round humid and mild temperatures with acidic soil and drainage. With a combination of luck and skill, rare palms may be coaxed into the unwelcomed environment of South Florida. Certainly, through our local garden tours, we've seen good evidence of "Florida friendly" palms co-existing with palms less adaptable to our environment.

Many links concern pests and diseases, the not-so-nice stuff that comes with growing palms, or anything else in South Florida. Never hurts to occasionally weed, mulch and fertilize your palms before going nuts on insecticides or fungal treatments. I'm learning this the hard way!

I've included some sage advice from some of our local experts on some of the more uncommon palms.

Why o why did my little palm die? "A little learning might be a dangerous thing, but for most of us, it's the best we can do." (apologies to Alexander Pope).

Palm Pests and Diseases

These links are focused on Florida's pests and diseases. Very often, the best advice comes from the University of Florida/ Institute of Food and Agricultural Sciences (UF/IFAS). They have posted numerous publications on the internet for homeowners, landscapers and nurseries.

*** Lethal Bronzing Articles

Lethal Bronzingpreviously called Texas Phoenix Palm Decline, is a relatively new bacterial disease (called a phytoplasma) that is causing significant palm losses in Palm Beach County.  Symptoms are similar to lethal yellowing, but affect a much smaller number of palm species.  The damaged vascular system of the palm leads to wilting, and eventually death.  University of Florida research is determining which sap feeding insect(s) may spread it.  Affected species include Sabal (Cabbage), Queen, Pygmy Date and other Phoenix species, Christmas, Bismarck, Chinese Fan and Carpentaria palms.

At present, there are no satisfactory treatments, so experts recommend removal as soon as the disease is confirm.

IFAS PP243/PP163 Lethal Bronzing Disease (LBD)

Dr. Badher helps in Saving Florida's Sabal Palms

I particularly like this: "Once it becomes so much more profitable to build than to farm, there’s no going back. I don’t know of a single mall that’s been converted into a strawberry field or a pine plantation. The sabal palm represents another part of our past worth preserving. If agricultural science doesn’t keep up with the disease that’s killing it, we’ll notice a slow die-off of iconic scenery. Until, one day, it’s gone in a blink."

FDACS Publication, Pest Alert, Lethal Bronzing

*** Bleeding Stem Disease (Trunk Rot)

A Florida resident recently sent us images of a coconut tree on the beach, oozing a brown liquid. Unfortunately, it was clear that his tree had bleeding stem disease. It was recommended that infected palms be removed and pruning equipment sanitized.

Storm damage recovery has suddenly become of great interest to our neighbors to the north.

This sage advice works well for the palms in our landscape in South Florida, with the additional suggestion of disease prevention for the recovering palms.
