Mature trees add beauty, shade, and value to properties throughout Tampa. While many trees remain healthy for decades, others can develop internal decay that weakens their structure long before obvious symptoms appear. Because decay often begins inside the trunk or major branches, homeowners may not recognize a problem until a limb breaks or the tree becomes hazardous. Learning to recognize the early warning signs can help you address problems before they become emergencies. Fungal Growth Around the Base of the Tree One of the most noticeable indicators of possible internal decay is the appearance of mushrooms or other fungal growth near the base of a tree or along the trunk. While not every fungus indicates serious structural problems, fungal growth may suggest that wood inside the tree is beginning to decompose. A professional evaluation is recommended if you notice: Mushrooms growing around the trunk. Shelf-like fungi attached to the bark. Repeated fungal growth in the same location. Early evaluation can determine whether the decay is primarily cosmetic or whether it has affected the tree's structural integrity. Cavities and Hollow Areas Small cavities do not always mean a tree is unsafe. Many mature trees continue to live with hollow sections for years. However, larger cavities or multiple areas of decay can reduce the tree's structural strength. Watch for: Large openings in the trunk. Soft or crumbling wood. Cavities that collect water. Areas where insects are frequently present. A professional inspection can determine whether the remaining healthy wood is sufficient to support the tree safely. Dead Branches in an Otherwise Healthy Tree A mature tree with a full canopy may still have isolated dead limbs caused by internal decay. Signs include: Branches that fail to produce leaves. Limbs with peeling bark. Dead branches concentrated on one side of the tree. Large limbs that break during normal weather conditions. Selective pruning may correct some problems, while others require closer evaluation. Cracks and Areas of Missing Bark Internal decay can weaken the trunk and major branches, making them more susceptible to cracking. Look for: Vertical cracks in the trunk. Bark separating from the wood. Long sections of missing bark. Areas that feel soft when gently pressed. These symptoms do not always indicate that removal is necessary, but they should never be ignored. Leaning or Unstable Trees Decay affecting the lower trunk or root system can reduce a tree's ability to remain stable. Pay close attention if a mature tree: Begins leaning more than before. Develops exposed roots after heavy rain. Shows soil movement around the base. Drops large limbs without severe weather. Because Tampa regularly experiences strong thunderstorms and tropical systems, even moderate structural weakness can increase the likelihood of tree failure. Professional Evaluation Makes the Difference Internal decay cannot always be confirmed by visual inspection alone. What appears to be a healthy tree may have hidden structural weaknesses, while a tree with visible cavities may remain stable for many years.
