How To Spot Hazardous Trees on Your Property
Trevor Soltys & Paul Kasper
Identify Structural Weaknesses and Potential Safety Risks
Trees add beauty, shade, and value to your property, but they can also pose serious risks if they become structurally compromised. Identifying hazardous trees early can prevent property damage, injuries, and costly emergency removals. Here’s how to spot structural weaknesses and potential safety risks in your trees.
1. Inspect the Tree’s Overall Health
Start by observing the tree’s general condition. A healthy tree has vibrant leaves, sturdy branches, and strong bark. Signs of a hazardous tree include:
- Sparse or discolored foliage
- Excessive dead branches
- Leaning trunk
- Fungal growth at the base
- Visible decay or cavities
2. Check for Cracks, Splits, and Cavities
Deep cracks or splits in the trunk or large branches indicate internal weaknesses. Cavities, especially large ones, may suggest decay and a compromised structure. If you notice significant cracks or holes, consult an arborist to determine the extent of the damage.
3. Look for Dead or Hanging Branches
Dead branches, also known as widow-makers, can fall unexpectedly, posing a severe risk to people and property. Signs of deadwood include:
- Bark that easily peels away
- Brittle, leafless branches
- Fungal growth on branches If you spot any of these warning signs, it’s best to have them removed immediately.
4. Examine the Tree’s Root System
The roots anchor a tree and provide essential nutrients. Root damage can cause instability, making the tree prone to falling. Warning signs include:
- Exposed roots with signs of decay
- Soil heaving or cracks around the base
- Leaning trees with weak root attachment If your tree’s roots appear damaged, it could be a sign that the tree is at risk of toppling over.
5. Identify Signs of Disease or Pest Infestation
Diseases and pests can weaken a tree’s structure over time. Look for these red flags:
- Holes in the bark (indicating insect activity)
- Sudden branch dieback
- Powdery mildew, cankers, or other fungal growth
- Unusual leaf discoloration or deformities If you suspect disease or pest infestation, early intervention can often save the tree.
6. Assess the Tree’s Lean and Stability
A tree naturally leans due to its growth pattern, but a sudden or severe tilt can indicate a structural issue. Signs of instability include:
- A tree leaning more than 15 degrees
- Exposed or lifted roots
- Recent soil disturbance around the base A leaning tree, especially after a storm, should be inspected by a professional immediately.
7. Observe the Surrounding Area
A tree’s environment plays a crucial role in its stability. Consider the following:
- Proximity to Structures: Trees too close to homes, driveways, or power lines may pose a risk if they fall.
- Soil Conditions: Poorly drained or compacted soil can weaken root systems.
- Previous Storm Damage: Trees that have lost large limbs or suffered storm damage may have hidden structural weaknesses.
What to Do If You Have a Hazardous Tree
If you notice any of these warning signs, don’t ignore them. Contact a tree service for a professional evaluation by a licensed arborist. In some cases, strategic pruning can resolve the issue, while in others, tree removal may be the safest option.
Regular inspections and preventative maintenance can help keep your trees healthy and your property safe. By being proactive, you can enjoy the benefits of trees without the risks.
Trees are more than just beautiful features in our landscapes — they are living investments that provide shade, beauty, and environmental benefits. However, like any valuable asset, trees require care and attention to stay healthy and safe. One of the most important, yet often overlooked, steps in maintaining your trees is scheduling regular inspections. Routine tree assessments are a proactive approach that can save property owners time, money, and stress in the long run. Catching Problems Early Just as we schedule regular checkups with a doctor or maintenance for our vehicles, trees benefit immensely from routine inspections. Trees are living organisms that can be affected by diseases, pests, structural weaknesses, and environmental stress. Unfortunately, many issues develop slowly and can go unnoticed until they become severe or even hazardous. A certified arborist or experienced tree professional can spot early signs of trouble that aren't obvious to the untrained eye. Issues such as fungal infections, root problems, structural cracks, or pest infestations can be addressed early, often with simpler and less expensive treatments. Early intervention can mean the difference between saving a valuable tree and facing the cost of removal and replacement. Promoting Long-Term Tree Health Regular inspections don't just catch problems — they actively contribute to the long-term vitality of your trees. By assessing soil conditions, pruning needs, and signs of nutrient deficiencies, tree professionals can recommend tailored care plans that promote healthy growth. For example, a tree that's beginning to show signs of stress due to compacted soil might benefit from soil aeration. A tree developing an uneven canopy may need selective pruning to rebalance its structure and encourage stronger growth. Without inspections, these opportunities to support tree health may be missed until visible decline occurs. Reducing Risk and Liability Beyond health benefits, regular tree assessments are critical for safety. Trees with hidden structural weaknesses, such as internal decay or unstable root systems, can pose significant risks to people and property, especially during storms. Branch failures or full tree collapses can lead to costly damages or injuries. By identifying and addressing hazards early, property owners can reduce their liability risks and create a safer environment for families, neighbors, and visitors. In many cases, insurance claims related to tree failures hinge on whether the property owner took reasonable steps to maintain the tree — routine inspections are a smart part of fulfilling that responsibility. Planning for the Future A proactive approach to tree care also allows for better planning. Through regular inspections, you can develop a long-term strategy for your landscape. This might include decisions about when to plant new trees, which species to select for your environment, and how to manage aging trees that may need eventual replacement. Rather than reacting to emergencies, you can manage your trees thoughtfully, preserving the beauty and value of your property for years to come. Conclusion Trees are resilient, but they are not invincible. Regular inspections offer a proactive, preventative approach that promotes tree health, enhances safety, and protects your investment in your landscape. Whether you have a single treasured oak or a yard full of ornamental trees, scheduling routine assessments with a qualified professional is one of the best steps you can take to ensure their health and longevity. Invest in regular tree inspections — your trees, and your future self, will thank you.
Trees are living structures, and like any structure, they can sometimes need a little extra support. Whether it's due to age, storm damage, or natural growth patterns, some trees develop structural weaknesses that make them more vulnerable to breakage or failure. That’s where cabling and bracing come in — two highly effective techniques for supporting trees and extending their lifespan. Let’s take a closer look at what cabling and bracing involve and how these structural support systems can help protect your trees, property, and peace of mind. What Is Cabling and Bracing? Cabling and bracing are proactive methods used by professional arborists to reinforce weak tree limbs or trunks, reduce the risk of breakage, and preserve valuable trees. Cabling involves installing high-strength steel cables high in the canopy between major limbs. These cables limit the movement of branches during strong winds or storms and reduce stress on weak or heavy limbs. Bracing involves inserting threaded steel rods through weak or split limbs or trunks to provide rigid support and prevent further splitting or failure. Used together or separately, these techniques help stabilize a tree without harming its natural appearance or health. When Are Cabling and Bracing Necessary? Cabling and bracing are typically recommended when: A tree has a split or cracked trunk or limb. A tree has co-dominant stems — two or more trunks growing from the same point, which often creates a weak attachment. A large, healthy tree has heavy limbs that are vulnerable to wind or snow load. You want to preserve a valuable or mature tree that might otherwise need to be removed due to structural risk. Arborists can assess a tree's structure and determine whether support systems are needed — and where they will be most effective. Benefits of Cabling and Bracing 1. Preserves Mature or Valuable Trees Some trees are simply irreplaceable — they may provide shade, beauty, history, or sentimental value. Cabling and bracing can often save a tree that might otherwise be lost due to structural weaknesses. 2. Prevents Property Damage A large branch or entire tree failure can result in serious damage to your home, vehicle, fence, or landscaping — not to mention the risk to people and pets. Reinforcing weak limbs helps prevent costly accidents. 3. Reduces Risk Without Removing the Tree Instead of taking down a tree preemptively due to safety concerns, cabling and bracing offer a way to mitigate risk while keeping the tree in place. It’s a win-win solution for both safety and sustainability. 4. Supports Natural Growth Cabling doesn’t restrict a tree’s growth — it simply helps guide it in a safe direction. Over time, many trees can adapt and strengthen around these supports. 5. Long-Term Cost Savings While installation and periodic inspections are an investment, cabling and bracing can save you money in the long run by avoiding emergency removals, repairs, or replacements. Professional Installation Matters It’s important to note that cabling and bracing should always be performed by a certified arborist. Improper installation can actually worsen a tree’s condition or create new risks. A professional will know the correct hardware, placement, and techniques to ensure the tree’s health and safety. Additionally, support systems should be inspected regularly to make sure they’re still functioning properly as the tree grows and changes.
When it comes to tree care, pruning is one of the most important — and most misunderstood — practices out there. While proper pruning can keep your trees healthy, safe, and beautiful, there are plenty of outdated or flat-out wrong ideas still circulating. Let’s break down some of the most common tree pruning myths and set the record straight. Myth #1: Topping a Tree Controls Its Size Truth: Topping is one of the most harmful things you can do to a tree. Topping involves cutting back large branches or the entire top of a tree to reduce its height. Many homeowners think this will help keep the tree "under control" or promote new growth. While it does force the tree to produce new shoots quickly, these new limbs are weakly attached and prone to breaking. Topping also removes a large portion of the tree’s leafy canopy, which it needs for photosynthesis. The result? A stressed, unstable, and often unhealthy tree. Instead of topping, proper crown reduction by a professional arborist can safely reduce a tree’s size while preserving its structure and health. Myth #2: Trees Should Only Be Pruned in the Spring Truth: The best time to prune depends on the type of tree and your goals. Spring is a common time for pruning, especially for flowering trees, but it’s not the only option. In fact, winter can be one of the best times for structural pruning. During dormancy, trees are less susceptible to pests and diseases, and it’s easier to see their branching structure without leaves in the way. That said, dead or hazardous branches should be removed as soon as they’re identified, no matter the season. Myth #3: Trees in Nature Don’t Need Pruning, So Why Should Mine? Truth: Urban trees are not growing in natural forest conditions. It’s true that trees in the wild aren’t routinely pruned, but they also aren’t planted near homes, power lines, or sidewalks. Trees in urban or suburban areas face different stressors — compacted soil, pollution, limited space, and more. Pruning helps manage risk, prevent damage, and guide growth in a way that’s safer for your property and healthier for the tree. Myth #4: All Pruning Is the Same Truth: There are different pruning techniques for different purposes. Pruning isn’t a one-size-fits-all job. Removing deadwood, thinning out crowded branches, lifting low limbs for clearance, and shaping for aesthetics all require different approaches. Over-pruning or using the wrong method can harm your tree more than help it. That’s why hiring a trained professional is key — they’ll know exactly how to make each cut to benefit the tree long-term. Myth #5: You Can Prune Anytime, Any Way You Like Truth: Bad pruning can cause permanent damage. Improper pruning, like making flush cuts or cutting in the wrong place, can leave trees vulnerable to pests, disease, and decay. It can also lead to poor growth patterns or long-term structural issues. Trees don’t "heal" the same way humans do — they compartmentalize wounds rather than repair them. Making the right cuts in the right places is critical to the tree’s future health. The Bottom Line Need help with your trees? Pruning is essential, but it must be done with care, knowledge, and the tree’s biology in mind. Don’t fall for the myths that can lead to unhealthy, unsafe, or unattractive trees. Whether you need routine maintenance or help correcting past pruning mistakes, trust an experienced tree care professional to get the job done right.
Trees are essential to a healthy landscape, offering shade, beauty, and environmental benefits. But while their canopies may be the most visible feature, it’s what lies beneath the surface—their root systems—that can sometimes cause concern for property owners. Tree roots are vital to the health of the tree, yet when they grow too close to homes, sidewalks, driveways, or underground utilities, they can potentially lead to costly damage. In this post, we’ll explore how tree root systems grow, why they sometimes cause property issues, and how you can protect both your trees and your property. How Tree Roots Grow Contrary to popular belief, tree roots don’t grow deep into the ground in a straight line like a taproot. Most tree roots grow outward, often extending two to three times beyond the canopy. In fact, the majority of a tree’s roots are found in the top 18 to 24 inches of soil, where oxygen, water, and nutrients are most readily available. There are two main types of roots: Structural roots, which anchor the tree and provide stability. Feeder roots, which are smaller and absorb nutrients and water. Roots will naturally grow toward moisture and nutrients, which is where problems can begin—especially if that moisture is coming from leaking pipes or foundation cracks. How Tree Roots Can Damage Property Roots are not inherently destructive, but when they encounter obstacles, they may grow around or even through them in their search for water. Here are some of the most common types of property damage associated with tree roots: Foundation Damage: While roots rarely break through a solid foundation, they can exploit small cracks or gaps, especially in older homes. As roots grow and expand, they can worsen these issues over time . Sidewalks and Driveways: Tree roots that grow just beneath the surface can push up concrete slabs, creating uneven or cracked pavement that’s both unsightly and hazardous. Plumbing and Sewer Lines: If there’s a crack or joint in an underground pipe, roots may infiltrate it in search of water. Over time, they can block the pipe entirely or cause it to burst. Landscape Disruption: Tree roots can disrupt lawns, gardens, and other plantings by absorbing most of the available water and nutrients or physically displacing soil. Preventing Root-Related Damage A little planning goes a long way when it comes to preventing tree root issues. Here are a few tips to protect your property: Plant the Right Tree in the Right Place: Avoid planting large, fast-growing trees too close to structures, driveways, or utility lines. Research the mature root spread of any tree before planting. Install Root Barriers: These physical barriers can be placed underground to guide roots away from sensitive areas like foundations or pipes. Monitor Tree Health: A healthy tree is less likely to become a problem. Regular maintenance, pruning, and inspection can help catch early signs of root issues. Consult a Professional: If you suspect root damage or are planning new plantings near your home or utilities, consider bringing in a certified arborist or a tree service professional. Final Thoughts Tree root systems are a natural and necessary part of any healthy tree, but they can pose risks when not properly managed. By understanding how roots grow and taking proactive steps, you can enjoy the benefits of trees while minimizing the risk of property damage. If you’re unsure whether a tree on your property is causing—or may cause—damage, reach out to a local tree expert for an assessment. It’s always better to address root issues early, before they lead to bigger (and more expensive) problems.
