What should our Florida HOA do when lethal bronzing shows up in the community's palms?

By OurHOA · General information · Revised October 31, 2026

What a Florida HOA board does when lethal bronzing hits its palms: lab-test suspects, remove positives fast, inject nearby palms and replant with non-host species.

Part of the HOA board handbook: vendors, projects and upkeep.

The short answer

Lethal bronzing is a bacterial disease of palms with no cure. Once a palm shows symptoms or tests positive, it is lost, and every week it stays standing gives sap-feeding insects more time to carry the disease to the palms around it. The board's job is a short, fast sequence: 1. Get a lab test on any palm that looks suspicious. 2. Remove every palm that tests positive, including positives that still look healthy. 3. Test the palms nearby and start preventive antibiotic injections on the clean ones, every three to four months for at least two years. 4. Replace lost palms with species that are not known hosts. UF/IFAS has confirmed the disease in 36 Florida counties, from Jacksonville to the Keys, and it has also been reported in Louisiana. It was first identified on Canary Island date palms in the Corpus Christi area of Texas, where it went by the name Texas Phoenix palm decline. This guide uses Florida's rules and resources. City tree ordinances and your own governing documents also shape what the association may do, so treat this as education, not legal advice. For routine palm care, see our guide on maintaining HOA palm trees in Florida.

Confirm it before anyone cuts

The UF/IFAS fact sheet PP243 (reviewed August 2025) gives the usual order of symptoms: - Fruit drops early, if the palm is fruiting. - If there is no fruit yet, the flower stalks turn black and die. - The oldest, lowest fronds discolor, and the bronzing moves up toward the younger fronds. - The spear leaf, the unopened frond in the center, collapses. At that point the bud is dead. Two details matter for a board. First, UF/IFAS puts the time from infection to the first symptom at about four to five months, and from first symptom to spear collapse at about two to three months, though it varies by species. So a palm that looks fine today can already be infected. Second, if the crew trims off flower and fruit stalks, or the palm is too young to flower, the earliest warning sign is gone. Some palms skip the discoloration and go straight to a collapsed spear. Only a lab test confirms it. UF/IFAS publication ENY-990 describes the sample: drill about two feet up the trunk, discard the brown outer pseudobark, and collect roughly two tablespoons (3 grams) of the off-white living tissue in a sealed bag, with the drill bit flame-sterilized between palms. Keep samples cold and ship them overnight, with the submission form, to the UF/IFAS Fort Lauderdale Research and Education Center lab that ENY-990 lists. Your county UF/IFAS Extension office can walk you through it, or a tree company that does palm work can pull the sample.

Remove positive palms the same week

PP243 is blunt: once a palm develops symptoms or tests positive, it is considered lost and should be removed immediately, because the label rate of the antibiotic does not reverse symptoms. The same goes for a palm that tests positive while still looking healthy. There will not be enough time for an injection to take effect before symptoms appear, so it comes out too. The urgency comes from the insects, not the debris. The disease lives only in the palm's sap-carrying tissue and in the insects that feed on it. PP243 says it cannot survive outside a plant or insect, so it does not spread on pruning tools or through roots touching. A standing infected palm is the problem. A palm on the truck is not. Practical steps: - Get two removal quotes the day the result comes back, with stump grinding as a separate line. - Ask the city or county whether a permit is needed to remove a diseased palm on association land, and get the answer by email. Our guide on removing a dead or dangerous tree on HOA common area covers the vote and the paperwork. - If your bylaws allow the board to act between meetings on urgent maintenance, use that authority and ratify the decision at the next open meeting. If they don't, call a special meeting rather than waiting a month. - Keep the lab report, the photos and the invoice in the tree file.

Test the neighbors, then protect the clean ones

PP243 recommends sampling the healthy-looking palms around a confirmed case. Testing finds hidden infections that need removal, and it tells you which palms are clean enough to protect. Neither UF/IFAS publication sets a distance, so ask the Extension agent or the arborist to mark a treatment zone on a site map, and record why that line was chosen. The protection is oxytetracycline hydrochloride (OTC), an antibiotic injected into the base of the trunk. PP243 says to inject clean palms near infected ones every three to four months for at least two years. UF/IFAS publication ENY998 describes quarterly injections through a valve set in a 5/16-inch hole drilled 6 to 8 inches into the trunk, with the bit flame-sterilized between trees. That is roughly eight visits per palm over two years, and each visit drills a new hole, so budget for the full program before you start. ENY998 also carries a caution boards should read before signing: the OTC recommendations were developed for lethal yellowing, a related disease, and had not yet been tested specifically against lethal bronzing. Injections appear to work best on healthy palms and give mixed results once symptoms appear. Treat them as reasonable protection, not a guarantee. What to put in the bid request: - A price per palm per injection visit, and the total for eight visits. - A tag number or map ID for every treated palm, and an injection log after each visit. - Flame-sterilized bits between trees. - The company's Florida pest control license number and certificate category. Fla. Stat. 482.111(2)(a) lists lawn and ornamental pest control as its own category. A crew member holding only the limited landscape maintenance certification under 482.156(1) is limited to handheld or backpack equipment and products with no signal word or a "caution" label, so confirm what the injecting technician actually holds.

Replant with species that are not hosts

PP243 lists 21 confirmed host species, and warns the list could grow as the disease moves south into areas with more palm variety. The hosts most likely to be on HOA common areas include cabbage (sabal) palm, queen palm, Canary Island date palm, edible date palm, pygmy date palm, wild date palm, Bismarck palm, Christmas palm, coconut palm, Chinese fan palm, pindo palm and Chinese windmill palm. A new sabal in an old sabal's hole is a new host where the insects are already active. Choose a species not on the current list, or a shade tree where it fits, and mix species along a drive. Before you settle on one, ask the Extension office to check it against lethal yellowing as well, since that related disease affects more than 30 palm species. Our Florida palm care guide also covers which species held up in hurricanes, which is worth weighing at the same time.

Owner palms and a notice you can send

Infected palms on private lots keep the disease going even when the association's palms are clean. Whether the association can require an owner to remove one depends on your declaration and architectural rules, which are often silent. Start with information. Sample notice: "Lethal bronzing, a palm disease with no cure, has been confirmed in a palm on [location]. The association removed the palm on [date] and is testing and treating nearby common-area palms. Early signs include fruit dropping early, blackened flower stalks and lower fronds turning bronze from the bottom up. If a palm on your lot shows these signs, contact the UF/IFAS Extension office in [county] about testing, and let the management contact know so we can track where the disease is showing up. Owners who replace palms may want to choose a species that is not a known host." Keep a simple map of confirmed cases, owner lots included. It tells the arborist where to test next.

Sample motion and timeline

Motion: "Move that the association remove the [species] palm at [location], which tested positive for lethal bronzing on [date], at a cost not to exceed $[amount]; that the [number] palms within the treatment zone on Exhibit A be tested at a cost not to exceed $[amount]; and that palms testing negative receive oxytetracycline injections every three months for two years under the attached proposal, with injection logs reported to the board after each visit." A typical sequence: - Day 1: a director or the landscaper spots early fruit drop or a bronzing lower canopy. Photograph it and call the tree company or the Extension office. - Days 2 to 3: sample collected and shipped overnight. - Result day: board approves removal and neighbor testing. - Within days of approval: palm removed. Neighbor samples collected. - Next month: first injections on palms that tested clean, removal of any hidden positives. - Every 3 months for 2 years: injections, the log, and a walk past every palm looking for new symptoms. Carry the program in the landscape budget until it ends.

Mistakes that spread it

- Waiting to see whether the palm recovers. It won't, and it is feeding the next infection while you watch. - Paying to inject a palm that already shows symptoms. UF/IFAS says the label rate is not enough to reverse them. - Removing the obvious palm and stopping there. Healthy-looking neighbors can already be positive. - Letting the crew trim every flower and fruit stalk, which hides the earliest symptom. Ask them to leave stalks on a few host palms in each area as early warning, or to report early fruit drop when they see it. - Starting injections without a log. Two years of quarterly visits is easy to lose track of when the board turns over. - Replanting the same host species in the same hole because it matches the rest of the row.
