Every tree on your property has the potential to become a hazard under the right circumstances, but some trees develop warning signs well in advance of failure. Learning to recognize those signs gives you the opportunity to take action before a branch crashes through your roof or a trunk splits during a storm. In Tallahassee, where mature trees are large, heavy, and often located close to homes and power lines, understanding what to look for is not just good practice -- it is an essential part of responsible property ownership.
Start your assessment at the base of the tree and work upward. At ground level, look for soil heaving or cracking on one side of the trunk, which can indicate that the root system is shifting and the tree may be leaning progressively. Mushrooms, conks, or bracket fungi growing at the base of the trunk or on surface roots are often signs of internal decay in the root system or lower trunk -- these fungi feed on dead and dying wood, and their presence means structural wood is being compromised. A trunk that has a pronounced lean, especially one that has developed recently or increased over time, warrants professional evaluation. Cavities, cracks, and areas of missing bark on the trunk are additional red flags, as they indicate areas where the wood is weakened.
Moving into the canopy, dead branches are the most obvious hazard. Any dead limb of significant size that overhangs a target -- your house, driveway, walkway, or play area -- should be removed promptly. Branches with tight, V-shaped crotch angles are weaker than those with wide, U-shaped attachments and are more likely to split apart during wind events. Codominant stems, where two trunks of roughly equal size emerge from the same point, are a common structural defect that can lead to catastrophic splitting. Look also for hanging branches that are caught in the canopy and could fall unpredictably, as well as branches that are in contact with or dangerously close to power lines.
Some hazards are invisible from the outside. Internal decay, root rot, and structural cracks can all exist without obvious external symptoms, which is why periodic professional inspections are so important -- especially for large trees near structures. A certified arborist has the training and tools to evaluate tree risk systematically, including advanced techniques like resistance drilling that can detect internal decay without harming the tree. In Tallahassee, where hurricanes and severe thunderstorms are a regular threat, proactive hazard identification is far less expensive than emergency cleanup and property repair. Miller's Tree Service offers comprehensive tree risk assessments that can identify problems early and recommend the most appropriate course of action, whether that is pruning, cabling, or removal.
