4 Seasons, 4 Trees: What to Look for in Each Season

When we think about tree health, most of us focus on what's visible—leaf color, branch condition, or bark texture. But hidden inside many trees is a silent threat: internal decay. Tree cavities can be more than just cosmetic defects—they may signal serious structural problems that could lead to branch failure or total tree collapse. At West Atlanta Tree Service , we believe prevention starts with awareness. Here’s what you need to know about tree cavities and how to spot signs of internal decay early. What Is a Tree Cavity? A tree cavity is a hollow area within the trunk or major branches of a tree. These voids typically result from decay fungi breaking down dead or injured wood tissue over time. While cavities might look minor on the surface, they can compromise the tree’s ability to support its own weight—posing risks to nearby structures, vehicles, and people. Common Causes of Tree Cavities Understanding the causes of cavities can help you avoid contributing to internal decay: Pruning wounds that weren’t sealed properly Storm damage that breaks bark and exposes the heartwood Insect infestations, especially borers and carpenter ants Fungal infections, like heart rot or white rot Mechanical injuries, such as lawnmower gashes or car impacts Each of these factors allows moisture and decay organisms to enter, gradually hollowing out the tree from within. How to Spot Internal Tree Decay Though internal decay is hidden, there are key warning signs that indicate a tree might be in trouble: 1. Visible Cavities or Holes Large holes in the trunk or branches often suggest advanced decay. Birds or squirrels may also nest in these hollows. 2. Mushrooms or Fungal Growth Fungi growing on bark—especially bracket fungi or conks—usually signal internal rot. These fruiting bodies often appear around the base or on the trunk. 3. Cracks in the Bark Vertical cracks or seams can mean the tree is weakening from the inside out, especially if accompanied by oozing sap or discoloration. 4. Soft or Spongy Wood Press on the trunk with a stick or tool. If it feels soft or spongy, decay has likely set in. 5. Unusual Leaning or Canopy Thinning A tree leaning more than normal or with noticeably thinning foliage may have lost its internal support structure. 6. Carpenter Ants or Termite Activity The presence of certain insects can indicate wood that is already decaying, providing a nesting site for pests. Is a Tree with a Cavity Always Dangerous? Not necessarily. Trees are resilient and may compartmentalize decay to keep it from spreading. However, if the cavity is large—especially in load-bearing parts of the tree—it could be structurally unstable. That's where professional assessment is critical. At West Atlanta Tree Service , we use resistograph testing, visual inspections, and sometimes sonic tomography to assess the true health of your trees and determine whether a cavity poses a safety risk. What Should You Do if You Suspect Internal Decay? Avoid DIY fixes like filling cavities with cement—this does more harm than good. Call a certified arborist to inspect the tree’s health. Consider bracing or cabling if the tree can be saved with structural support. Schedule tree removal if the decay is extensive and the tree poses a danger. Preventing Tree Cavities in the First Place Prevention is always better than treatment. Here are a few tips to help your trees resist decay: Prune only during the dormant season and make clean, proper cuts. Avoid damaging roots or bark with mowers or vehicles. Mulch around the base of the tree to protect against injury. Monitor trees regularly for early signs of trouble.

When it comes to healthy, long-living trees, there’s no fast track. Trees, like many things in nature, thrive on patience—and that includes how they receive nutrients. One of the most effective ways to nourish your trees is through slow-release fertilizers . At West Atlanta Tree Service , we often recommend this method to our clients across the West Atlanta region for its long-term benefits and lasting impact on tree health. What Is Slow-Release Fertilizer? Unlike quick-release fertilizers that deliver a surge of nutrients all at once, slow-release fertilizers break down gradually over time, mimicking the natural nutrient cycle found in forests. These fertilizers release nutrients steadily, typically over a span of weeks or even months, depending on the formulation and environmental conditions. The Benefits of Gradual Nutrient Release for Trees 1. Promotes Stronger Root Development Trees rely heavily on robust root systems for stability, nutrient absorption, and drought resistance. The consistent feed from slow-release fertilizers encourages deeper, more extensive root growth compared to the short-lived spike caused by quick-release products. 2. Reduces Risk of Nutrient Burn Too much of a good thing can be harmful. Quick-release fertilizers often deliver high concentrations of nitrogen, which can burn roots and leaves. Slow-release formulas deliver nutrients in manageable doses, minimizing the risk of overfeeding. 3. Supports Long-Term Tree Health Trees are long-term investments. By providing a steady nutrient supply, slow-release fertilizers support consistent growth, stronger canopies, and improved resistance to pests and diseases—especially important for the diverse tree species in West Atlanta’s residential and commercial landscapes. 4. Minimizes Environmental Runoff Because slow-release fertilizers break down gradually, they’re less likely to wash away in the rain and pollute local waterways. This eco-friendly option is a smart choice for property owners concerned about sustainability and environmental impact. 5. Reduces Maintenance Needs With nutrients delivered steadily over time, you don’t need to reapply as often. That means fewer treatments and less effort, while still giving your trees exactly what they need—perfect for busy homeowners and property managers alike. Ideal Times to Apply Slow-Release Fertilizer in West Atlanta Timing matters. For most trees in West Atlanta, the early spring and early fall are ideal times for slow-release applications. This ensures nutrients are available during periods of active growth or root development. However, different species and soil conditions may require tailored treatment plans—something we specialize in at West Atlanta Tree Service.
