Lethal Bronzing was first reported in Hillsborough County in 2006. It is closely related to Palm Lethal Yellowing and is caused by a mollicute very similar to bacteria but without a cell wall. The disease was first detected in Texas in the early 1980s and has since spread, with cases reported in Louisiana, Florida and up into the Carolinas. The disease has been confirmed in just over 30 counties in Florida since it was first reported. 

The spread of Lethal Bronzing is typically attributed to an insect , no bigger than a grain of rice, commonly known as a treehopper. (Haplaxius Crudus) The infected ‘bug’ transfers a parasitic bacteria into a healthy palm while it feeds. This bacteria multiplies and essentially blocks the vascular network of the tree, causing the circulation of sugars and other nutrients to be hindered and ultimately stopped. The tree is literally killed from the inside.

Several types of Florida palms including the Sabal, Queen, Christmas and Sylvester (or Phoenix) are susceptible to LBD or Lethal Bronzing Disease. The rapid spread of the disease can be partially explained by the popularity and use of Sabals along the interstate system and Sylvester palms in resorts throughout the state. An infected palm can go months before it shows signs of the disease. Some common symptoms include browning or bronzing of lower foliage which then moves upward, dropping of fruit, further leaf collapse and death. Once a tree is diagnosed with LBD, it needs to be removed and other surrounding trees should be inspected as well.

Why This Is the Best Time to Check for Hidden Problems
By Mid-Florida Tree Service February 13, 2026
Trees add beauty, shade, and value to properties throughout Polk County. From Lakeland to Bartow to Mulberry, mature oaks, pines, and palms are a major part of the landscape. However, Florida’s climate creates unique challenges that can affect tree health if problems are not identified early. Understanding common tree issues in Polk County helps homeowners protect their investment and avoid costly removals. Storm Damage and Structural Weakness High winds and heavy rain are common throughout Polk County. Even if a tree survives a storm, hidden structural damage may remain. Common storm related issues include: Cracked or split trunks. Limbs with weak attachment points. Leaning trees due to root movement. Canopy imbalance after major limb loss. Internal decay caused by storm wounds. Early evaluation can determine whether corrective pruning can restore stability or if removal is necessary. Soil Compaction and Root Stress Many Polk County yards experience compacted soil due to foot traffic, construction, or heavy equipment. Compacted soil restricts oxygen flow to roots and limits water absorption. Signs of root stress include: Sparse canopy growth. Smaller than normal leaves. Premature leaf drop. Slow overall growth. Increased susceptibility to pests and disease. Relieving soil compaction and improving root conditions often restores tree vitality. Pest and Disease Issues Florida’s warm climate supports a wide range of pests and fungal diseases. Oaks, pines, and palms are especially vulnerable if already stressed. Common problems in Polk County include: Fungal growth at the base of trees. Leaf discoloration or spotting. Bark separation or oozing sap. Palm nutrient deficiencies. Insect activity in weakened wood. Our ISA Certified Arborists evaluate symptoms carefully before recommending treatment or removal. Improper Pruning Improper trimming can cause long term structural problems. Over pruning, topping, or removing healthy limbs weakens the tree and increases storm risk. We frequently see: Excessive canopy thinning. Large flush cuts that do not heal properly. Unbalanced canopy weight. Stress from removing too many green fronds on palms. Corrective pruning helps restore structure and reduce future risk. Root Damage From Construction Driveways, patios, and landscaping projects can damage roots without obvious signs at first. In Polk County neighborhoods with mature trees, root disturbance is a common cause of decline. Warning signs may include: Gradual thinning of the canopy. Increased branch drop. Soil settling near the base of the tree. Delayed decline months after construction. Professional evaluation helps determine whether damage can be managed. Proactive Tree Care in Polk County Most serious tree problems begin with subtle warning signs. Regular inspections and routine maintenance reduce the likelihood of emergency removals and storm failures.
