What Certified Arborists See That You Might Miss

Protect Your Property with Professional Tree Care

Trees can be one of the most beautiful and valuable features on your property—but they also require expert care. While most homeowners can spot a clearly dead tree or a broken limb after a storm, many of the early warning signs of trouble go unnoticed until it is too late.


That is where a certified arborist comes in. At Midwest Tree Surgeons, our team includes trained professionals who understand not only the biology of trees, but also the structural, environmental, and safety risks they may pose—especially during the fast-growing summer months.

Here is what certified arborists are trained to look for that most people miss:

1. Subtle Signs of Disease

Fungal infections, insect infestations, and internal decay often begin deep inside the trunk or below the bark. Symptoms like leaf discoloration or minor trunk cracks might seem harmless, but to a trained eye, they could point to systemic disease. Arborists can distinguish between normal seasonal changes and early indicators of serious issues, allowing for timely intervention before the tree becomes a hazard.


2. Structural Weaknesses

A tree can appear healthy while hiding major structural flaws. Arborists assess the integrity of trunks, branches, and root systems. They look for co-dominant stems (when two main trunks grow from a single point), including bark, and stress cracks—flaws that can make a tree more likely to fail in high winds or heavy storms.


Our team uses both visual inspection and tactile tests to identify limbs or trunks under tension or at risk of failure, especially after strong weather or long dry spells.

3. Risk to People, Homes, and Infrastructure

Certified arborists are trained in risk assessment standards that go beyond aesthetics. They evaluate how close branches are to homes, roofs, vehicles, utility lines, sidewalks, and other structures. What may seem like a nicely shaded porch to a homeowner might represent a serious liability in the event of limb drop or root upheaval.


We also look underground. Shifting soil, exposed roots, or subtle lean angles can signal a tree’s declining stability. Left unaddressed, these issues may lead to costly damage or even personal injury.


4. Pruning Opportunities That Promote Long-Term Health

A quick DIY trim might seem sufficient, but incorrect pruning can do more harm than good. Arborists know when and how to remove specific limbs to encourage balanced growth, reduce wind resistance, and improve airflow through the canopy. This kind of proactive maintenance can extend a tree’s life by decades while making it safer and more attractive.

5. Tree Species Behavior

Different species have different vulnerabilities. Some trees are highly susceptible to storm damage, while others are prone to root rot or pest infestations in certain soil conditions. Our arborists take these factors into account, tailoring care plans to your property’s specific mix of trees and environmental factors.


Why Certification Matters

Not all tree services are created equal. Certification means your arborist has been trained and tested in best practices for tree care and risk management. At Midwest Tree Surgeons, every job is overseen by a certified arborist who is committed to safety, health, and precision.


We do not guess—we diagnose, recommend, and execute with professionalism and care.

Some trees become more than landscaping .  They become landmarks . A mature oak near the driveway, an old maple shading the backyard, or a large tree that has stood beside a home for generations can become part of how people recognize and remember a property. That kind of tree has value that is difficult to measure with size alone. It can shape the look of the land, provide shade, frame views, and create a sense of permanence that younger landscaping simply cannot reproduce overnight. That is why preserving a healthy, long-lived tree can be worth serious consideration.

Mushrooms or other fungal growth on a tree trunk can look harmless, especially if the tree still has a full canopy. But fungal growth can sometimes be a sign that wood inside the tree is beginning to decay. That does not mean every mushroom automatically makes a tree dangerous. It does mean the tree deserves a closer look, particularly when the fungus is growing directly from the trunk, root flare, or a large structural root. For homeowners, recognizing that warning sign early can make it easier to evaluate the tree before a hidden problem becomes more serious.

Tree-of-heaven sounds harmless, but Ailanthus altissima is an aggressive invasive tree that has become established throughout much of the United States, including the Midwest. Originally native to China and Taiwan, tree-of-heaven was introduced to the United States in the late 1700s as an ornamental tree. Its ability to tolerate poor soil, pollution, disturbed ground, and difficult urban conditions helped it spread far beyond cultivated landscapes. Today, it can be found along roadsides, rail corridors, vacant lots, woodland edges, and other disturbed areas throughout the Midwest. Knowing how to recognize it is important because removing it incorrectly can actually make the infestation worse. Look Closely at the Leaves Tree-of-heaven has very large compound leaves made up of numerous individual leaflets. A single leaf can contain roughly 10 to 40 or more leaflets arranged along a central stem. Near the base of each leaflet are distinctive glandular teeth or notches that can help separate tree-of-heaven from similar-looking native species. Crushing the foliage is another useful clue. The leaves can produce a strong, unpleasant odor that has sometimes been compared to rancid or burnt peanut butter.

Winter can place significant stress on trees, especially when heavy snow, ice, strong winds, and rapid temperature changes arrive together. A tree that appears stable in mild weather may react very differently once branches are loaded with snow or the soil freezes. That is why late fall is a useful time for homeowners to look for warning signs before severe winter weather begins. A careful inspection can help identify weak branches, structural defects, and other concerns that may become more dangerous during a storm.

Evergreens are often valued because they provide year-round color, screening, and structure in the landscape. When sections of an arborvitae, juniper, spruce, or similar evergreen suddenly begin turning brown or losing foliage, however, bagworms may be responsible. Bagworms are caterpillars that construct protective bags from silk and pieces of the plants they are feeding on. Because those bags blend into surrounding foliage, an infestation can become significant before the insects attract much attention. Understanding how bagworms feed and when they are easiest to control can help protect valuable trees and shrubs from unnecessary damage. The Bags Can Be Easy to Miss Bagworms get their name from the portable cases they build around themselves. As the larvae feed , they add pieces of needles, leaves, and twigs to the outside of the bag. This camouflage can make them difficult to recognize, particularly when populations are still relatively small. The bags may look like small brown cones or pieces of dried vegetation hanging from the branches. Penn State Extension notes that bagworms can become serious pests on arborvitae, juniper, spruce, fir, and other conifers because substantial feeding damage can occur before the infestation becomes obvious.

Fall is an especially useful time to take a closer look at the structure of mature trees . As leaves begin to thin and eventually drop, branches, unions, cracks, cavities, and other structural features become easier to see.  That makes autumn a practical season for identifying problems that may be harder to spot during summer. It also gives homeowners time to address weak limbs or other concerns before winter snow, ice, and wind place additional stress on the canopy.

A healthy tree should not look like a telephone pole entering the ground. Near the base of the trunk, the tree should widen where the major roots begin to spread outward. This area is known as the root flare, and it can reveal a great deal about whether a tree was planted at the correct depth.  When the root flare is buried under soil, mulch, or landscaping material, the tree may face long-term problems that are easy to miss at first. Looking at the base of the trunk is one of the simplest ways to spot a planting issue before it becomes more serious.

A tree can appear healthy overall and still develop a section of dead or dying branches. When branch dieback appears suddenly, especially in one part of the canopy, it can be a sign that something is interfering with the tree’s ability to move water and nutrients where they are needed.  For homeowners, the important question is not simply whether a branch is dead, but why it died. Midwest Tree Surgeons evaluates tree health, structure, pests , disease, and site conditions to help determine what may be causing the change.

When a tree grows too large for its surroundings, removing the upper portion of the canopy may seem like a quick solution. This practice, commonly called tree topping, involves cutting major branches or leaders back to stubs or lateral branches that are too small to assume the terminal role.  Although topping can immediately reduce a tree’s height, it can also create lasting structural and health problems. For homeowners concerned about an oversized or potentially hazardous tree, professional pruning is generally a better approach.

When insects begin damaging a tree, the first instinct may be to treat the problem as quickly as possible. But not every insect requires the same response, and some insects that look harmful may not be the actual cause of the decline. Applying the wrong treatment can waste time, money, and potentially put additional stress on the tree.  Midwest Tree Surgeons takes a diagnosis-first approach to tree care. Correct pest identification helps determine whether treatment is needed, which method is appropriate, and whether the real problem may involve disease, environmental stress, or another underlying issue.
