What Certified Arborists See That You Might Miss

June 27, 2025

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.

Why Correct Pest Identification Matters Before Treatment

August 18, 2026

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.

What Cankers Can Tell You About Tree Stress

August 11, 2026

Trees often show signs of trouble long before they experience major decline. One warning sign that deserves attention is the appearance of a canker—a localized area of dead or damaged bark that develops on a trunk, branch, or stem. Cankers can be caused by fungi, bacteria, environmental injury, or a combination of stress factors, and they often reveal that a tree is struggling to defend itself. While not every canker means a tree is doomed, these lesions can provide valuable clues about underlying health problems. Midwest Tree Surgeons helps property owners evaluate symptoms such as bark damage, dieback, discoloration, and structural weakness so that appropriate care can begin before problems become more severe.

Recognizing Pine Bark Beetle Activity Before Serious Tree Damage Occurs

August 6, 2026

Pine trees are valued throughout the Midwest for their year-round beauty, wind protection, and ecological importance. Although these evergreens are generally hardy, they can become vulnerable to insect pests when stressed by drought, storm damage, construction activity, or disease. One group of insects that deserves particular attention is the pine bark beetle . While these beetles are small, their activity can have significant consequences for individual trees and, in some situations, entire stands of pines. Recognizing the early signs of bark beetle activity allows property owners to respond before damage becomes more extensive. Professional evaluation is often the best way to determine whether a tree can be preserved or whether additional management measures are appropriate.

Why Some Trees Live for Hundreds of Years

July 28, 2026

Standing beneath a towering oak or sycamore, it is easy to appreciate a tree’s size. What is less obvious is its age. Many of the mature trees found throughout Missouri and the greater American Midwest have been growing for generations, quietly enduring changing weather, shifting landscapes, and the passage of time. While no tree lives forever, some species possess remarkable longevity, allowing them to become living landmarks that connect communities with their natural history. Understanding why certain trees live for centuries can help property owners appreciate the importance of proper tree care and preservation.

Understanding How Trees Heal After Pruning

July 21, 2026

Pruning is one of the most valuable services a professional arborist can provide, yet it is often misunderstood. Some homeowners worry that removing healthy branches may harm a tree, while others assume pruning is only necessary when limbs become hazardous. In reality, proper pruning is a proactive practice that supports tree health, improves structure, and helps trees adapt to changing environmental conditions. When performed correctly and at the appropriate time, pruning works with a tree’s natural biological processes, allowing it to continue growing safely and efficiently for years to come.

How Arborists Help Extend the Life of Valuable Trees

July 14, 2026

Trees are among the longest-living features on any property. A mature oak, maple, or other established tree may take decades to reach its full size, providing shade, beauty, wildlife habitat , and increased property value along the way. Because of the time and environmental benefits they represent, preserving healthy trees whenever possible is often a worthwhile investment. Professional arborists play an important role in helping trees remain healthy, structurally sound, and capable of thriving for many years. Through regular evaluations and proactive care, they can identify potential problems early and recommend treatments that support long-term tree health.

How Trees Support Wildlife Throughout the Year

July 8, 2026

Trees do much more than provide shade and enhance the beauty of a landscape. They are living ecosystems that support a remarkable variety of wildlife throughout every season. From nesting birds in the spring to sheltering mammals during the winter, healthy trees provide food, protection, and habitat for countless species. For homeowners and property managers , understanding the connection between trees and wildlife offers another reason to invest in professional tree care. Proper maintenance not only helps preserve the health and appearance of trees but also supports the many forms of life that depend on them.

How Arborists Evaluate Tree Risk

June 30, 2026

Trees add beauty, shade, and value to residential and commercial properties, but like any living organism, they change over time. While many trees remain healthy for decades, others may develop structural weaknesses that increase the likelihood of branch failure or even complete tree failure. Identifying these concerns is not always straightforward. A tree may appear healthy on the outside while hiding internal defects, or it may display subtle warning signs that only a trained professional can recognize. That is why professional tree risk assessments are an important part of responsible property management. Certified arborists evaluate much more than whether a tree looks healthy. Their goal is to determine how likely a tree is to fail, what the consequences of that failure could be, and whether any corrective action is appropriate.

Why Native Trees Continue to Be Important

June 24, 2026

When planning a landscape, homeowners often focus on appearance, growth rate, shade potential, or seasonal color. While these factors certainly matter, another important consideration is whether a tree is native to the region. Native trees have evolved alongside local soils, weather conditions, wildlife, and ecosystems for thousands of years. As a result, they often play a critical role in maintaining healthy landscapes and supporting the natural environment. Although non-native species can sometimes thrive in residential settings, native trees continue to provide unique benefits that make them valuable additions to properties and communities alike. Understanding why native trees remain important can help property owners make informed decisions about their landscapes.

How Japanese Beetles Affect Trees During the Summer Months

June 17, 2026

Summer brings plenty of activity to the landscape , but not all of it is beneficial. While homeowners often focus on watering, mowing, and maintaining their outdoor spaces during the warmer months, another seasonal visitor can create significant problems for trees and plants: the Japanese beetle. Japanese beetles are among the most recognizable insect pests found throughout much of the Midwest. Their metallic green bodies and copper-colored wings make them easy to identify, but the damage they leave behind is often what attracts the most attention. During peak summer months, large populations of these insects can feed on a variety of trees and ornamental plants, affecting both appearance and overall plant health. Understanding how Japanese beetles impact trees can help homeowners recognize potential problems and determine when professional assistance may be beneficial.
