Tree Pruning Myths That Could Harm Your Landscape

August 20, 2025

Pruning is one of the most important aspects of tree care. When done correctly, it improves the health, safety, and appearance of your trees. However, when done poorly or based on incorrect assumptions, it can cause lasting damage. At Midwest Tree Surgeons, we often encounter homeowners who have heard common myths about pruning that could put their trees at risk. By understanding these misconceptions, you can make better choices for your landscape.

Myth 1: Topping a Tree Helps Control Growth

One of the most persistent myths is that topping, or cutting off the top of a tree, is a safe way to reduce height. In reality, topping severely damages the tree by removing its main branches and exposing large areas of bark. This leads to decay, weak regrowth, and in many cases, early tree death. The practice also increases the risk of falling limbs because the new shoots that emerge after topping are poorly attached. Proper crown reduction performed by a professional is a much safer and healthier way to manage tree size.

Myth 2: Trees Can Be Pruned at Any Time of Year

It may seem convenient to prune whenever you notice a branch that looks out of place, but timing matters. Pruning during the wrong season can stress the tree, leave it vulnerable to pests, or prevent it from healing properly. For most species, late winter or early spring is ideal because the tree is dormant, and wounds will heal quickly when growth resumes. Summer pruning can also be beneficial in certain cases, but it is always best to consult with professionals who know the growth cycles of different species.

Myth 3: Sealants Are Necessary After Every Cut

Decades ago, it was common practice to apply paint or tar to pruning cuts with the idea that it would prevent infection. Research has since shown that trees naturally form callus tissue to seal wounds, and adding chemicals can actually trap moisture and promote decay. The healthiest approach is to make clean cuts at the correct angle and allow the tree to heal naturally.

Myth 4: Removing Large Limbs Will Not Harm the Tree

Sometimes homeowners believe they can remove large branches without consequence. While it may seem like a simple fix, removing major limbs creates large wounds that are difficult for the tree to close. This leaves the tree open to pests and decay. If large branches truly must be removed, the cut should be made carefully to avoid tearing the bark, and the overall balance of the canopy should be preserved.

Myth 5: Pruning Encourages Faster Growth

Many assume that pruning stimulates growth in the same way trimming a hedge does. While pruning can redirect energy to other parts of the tree, excessive or improper cuts often stunt growth instead of encouraging it. Over-pruning removes the leaves that trees need for photosynthesis, limiting their ability to create energy. The result is often a weaker, less resilient tree.

The Right Way to Prune

Pruning is both a science and an art. It requires an understanding of tree biology, growth patterns, and structural integrity. Professional arborists use precise techniques to:

Remove diseased or damaged branches without stressing the tree
Improve air circulation and light penetration
Shape the tree while maintaining its natural form
Prevent hazards by eliminating weak or crossing branches

By trusting trained experts, you can ensure that your trees receive the care they need without the risks associated with common myths.

Why Professional Pruning Matters

DIY pruning may save money in the short term, but the long-term damage caused by improper cuts can be costly. Trees are valuable assets to your property, adding beauty, shade, and even increasing home value. Professional pruning protects that investment while reducing the risk of accidents or tree loss.

At Midwest Tree Surgeons, we approach every pruning project with precision and care. Our team understands the myths that often mislead homeowners and replaces them with proven practices that keep trees strong and landscapes thriving.

Final Thoughts

Tree pruning is essential, but it must be done correctly. By avoiding myths such as topping, unnecessary sealants, or year-round trimming, you can preserve the health and beauty of your trees. Partnering with experienced professionals ensures your landscape remains safe, vibrant, and ready to flourish for years to come.

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.
