How Deadwood Accumulation Increases Safety Hazards Over Time

January 7, 2026

Deadwood accumulation is one of the most common and overlooked safety concerns in mature trees. While a tree may appear healthy at a glance, dead branches within the canopy can present serious risks to people and property below. At Midwest Tree Surgeons, we frequently encounter situations where deadwood has gone unnoticed until it causes damage or creates a dangerous condition. Understanding how deadwood develops and why it poses increasing hazards over time is essential for responsible property ownership.

What Deadwood Is and How It Develops

Deadwood refers to branches or limbs that are no longer living and actively growing. These branches may die due to age, disease, pest activity, storm damage, or environmental stress. In the Midwest, temperature extremes, freeze and thaw cycles, drought conditions, and severe storms all contribute to branch dieback.


Unlike living wood, deadwood no longer receives nutrients or moisture. As a result, it begins to dry out, lose flexibility, and weaken structurally. While a dead branch may remain attached to the tree for months or even years, its strength steadily declines.

Why Deadwood Becomes More Dangerous Over Time

As deadwood dries, it becomes brittle. This brittleness makes it far more susceptible to breaking under stress. Wind, snow accumulation, ice, or even the natural movement of the tree can cause dead branches to snap without warning.


Because deadwood often exists high in the canopy, falling branches can gain significant momentum before reaching the ground. This increases the potential for injury or damage to roofs, vehicles, fences, and outdoor living areas. Even relatively small branches can cause serious harmwhen they fall from height.

Hidden Risks in Seemingly Healthy Trees

One of the challenges with deadwood is that it is not always obvious from the ground. Dense foliage can conceal dead branches, especially during the growing season. Property owners may assume a tree is healthy based on leaf coverage alone, unaware of structural hazards developing overhead.


Deadwood can also shift position as surrounding branches grow or move. A branch that appears stable may become dislodged as the tree responds to wind or seasonal changes. This unpredictability makes deadwood particularly hazardous.

Increased Risk During Storms and Seasonal Changes

Weather events significantly increase the likelihood of deadwood failure. High winds place stress on weakened branches, while snow and ice add weight that deadwood cannot support. In the Midwest, winter storms and spring thunderstorms frequently expose deadwood issues that have developed quietly over time.


Temperature fluctuations also play a role. As wood expands and contracts, cracks can widen, further weakening dead branches. Over multiple seasons, this repeated stress accelerates deterioration.

How Deadwood Affects Overall Tree Health

Beyond safety concerns, deadwood can negatively impact the tree itself. Dead branches may attract insects or decay organisms that can spread into healthy tissue. This can lead to further decline and increase the likelihood of additional branch failure.


Removing deadwood helps redirect the tree’s resources toward healthy growth. It also reduces unnecessary stress on the remaining structure, supporting better long term stability.

The Importance of Professional Evaluation

Properly identifying and addressing deadwood requires experience and training. Removing dead branches involves assessing their size, location, and attachment points. Improper removal can create additional hazards or damage the tree.


At Midwest Tree Surgeons, we evaluate trees for deadwood accumulation as part of a broader risk assessment. We look for signs of decay, structural weakness, and potential failure points. This allows us to recommend appropriate action based on the specific conditions of each tree and its surroundings.

Proactive Management Protects People and Property

Deadwood accumulation does not resolve itself and becomes more dangerous the longer it remains unaddressed. Proactive assessment and removal reduce the risk of unexpected branch failure and help maintain a safer environment around homes, walkways, and outdoor spaces.


By addressing deadwood early, property owners can prevent accidents and preserve the overall health of their trees. At Midwest Tree Surgeons, we focus on identifying hazards before they lead to damage, helping our clients protect both their landscapes and their peace of mind.

How Bagworms Can Damage Evergreens

September 23, 2026
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.

Why Fall Is a Good Time to Evaluate Tree Structure

September 18, 2026
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.

What Root Flare Can Tell You About Planting Depth

September 10, 2026
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.

What Sudden Branch Dieback Can Mean

September 2, 2026
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.

Why Topping a Tree Can Create Long-Term Problems

August 25, 2026
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.

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.
