The Impact of Invasive Pest and Plant Species on Your Trees: How to Combat The Threat

Trevor Soltys & Paul Kasper

Trees are vital to the health and beauty of our landscapes, offering shade, clean air, and wildlife habitat. But these natural assets are increasingly under attack from an often overlooked enemy: invasive pest and plant species. These invaders can cause significant damage to your trees, weakening them, stunting their growth, or even killing them entirely. Understanding the threat they pose and knowing how to fight back is essential for homeowners and property managers alike.


The Growing Threat of Invasive Species

Invasive species are non-native organisms introduced—intentionally or accidentally—into an ecosystem where they lack natural predators or controls. Without anything to keep their populations in check, these species spread rapidly and often outcompete native flora and fauna for resources.


When it comes to trees, invasive pests and plants can be especially destructive. Invasive insects like the Emerald Ash Borer, Spotted Lanternfly, and Asian Longhorned Beetle have wiped out millions of trees across the U.S. and CANADA. They burrow into bark, feed on sap or leaves, and ultimately weaken the tree from the inside out.


On the plant side, species like English Ivy, Kudzu, and Tree-of-Heaven can overrun an area, choking out native plants, strangling young trees, and competing aggressively for sunlight, water, and soil nutrients.


Signs of Invasive Damage

You might not notice the problem right away, but the signs of invasive damage become more visible over time:

  • Thinning Canopy: Trees may lose leaves prematurely or appear sparse.
  • Bark Damage: Look for small holes, sawdust-like material, or peeling bark.
  • Sucker Growth: Stress caused by pests may trigger unwanted shoots from the tree’s base.
  • Vine Overgrowth: Fast-growing vines like kudzu or ivy climbing up a tree can suffocate it.

Early detection is crucial. The sooner you recognize these symptoms, the better your chances of saving the tree.


Combating the Invasion

Fighting invasive species requires a proactive approach, combining prevention, monitoring, and treatment:


1.  Know What to Watch For

Learn about the invasive pests and plants that are common in your region. Local extension offices, arborists, or state forestry departments often have updated lists and images. Being able to identify potential threats is the first step in stopping them.


2. Practice Smart Landscaping

Avoid planting known invasive species, even if they’re available at your local garden center. Opt for native or non-invasive alternatives that support the local ecosystem. If invasive plants are already present on your property, remove them carefully and dispose of them properly to prevent spread.


3.  Inspect Trees Regularly

Keep an eye on your trees throughout the year. Look for any changes in foliage, bark, or general structure. The earlier you catch an infestation, the easier it is to manage.


4. Consult a Professional

A certified arborist can assess tree health, diagnose pest issues, and recommend treatment options, such as targeted insecticide applications, pruning, or even tree removal if necessary to protect others nearby.


5. Stay Informed and Report Sightings

Some invasive species are part of state or federal tracking programs. Reporting sightings can help authorities manage outbreaks and protect wider ecosystems.


Protecting Your Green Assets

Your trees are long-term investments in your property’s value and your community’s environmental health. Invasive pests and plants threaten more than just aesthetics—they disrupt ecological balance and can cost thousands in damage and removal.


By staying vigilant, choosing native plants, and acting quickly when you notice a problem, you can help protect your trees from these silent invaders. If you’re unsure where to start, contact a local tree care professional to assess your landscape and offer expert guidance.

When it comes to boosting property value, homeowners often think of kitchen remodels, fresh paint, or new flooring. But one of the most overlooked—and cost-effective—ways to enhance your home’s appeal and worth lies just outside your front door: your trees. Proper tree care doesn’t just beautify your landscape; it can significantly increase your property’s market value. Let’s explore how investing in tree maintenance pays off both aesthetically and financially. 🌳 Curb Appeal That Captivates First impressions matter. A well-landscaped yard with healthy, mature trees creates an inviting atmosphere that immediately elevates a property’s curb appeal. Trees provide structure, shade, and visual interest, framing your home in a way that feels both natural and intentional. Seasonal beauty : Trees offer year-round charm—from spring blossoms and lush summer canopies to vibrant fall foliage and sculptural winter silhouettes. Defined spaces : Strategically placed trees can define outdoor areas, creating cozy nooks, shaded patios, or natural privacy screens. Neighborhood prestige : Homes in tree-lined neighborhoods often appear more established and desirable, which can influence buyer perception and even neighborhood property values. 💰 Tangible Financial Gains Beyond aesthetics, well-maintained trees can deliver a measurable return on investment. According to the Arbor Day Foundation and various real estate studies, mature trees can increase property values by as much as 10% to 20%. Here’s how: Energy savings : Trees provide natural cooling in the summer and windbreaks in the winter, reducing energy bills. The U.S. Department of Energy estimates that properly placed trees can cut air conditioning costs by up to 35%. Stormwater management : Healthy trees absorb rainwater and reduce runoff, which can lower the risk of flooding and erosion—especially important in urban or flood-prone areas. Environmental incentives : Some municipalities offer tax breaks or incentives for maintaining trees or planting new ones, adding another layer of financial benefit. 🛠️ The Importance of Proper Tree Care Not all trees are created equal—and neither is all tree care. Neglected or poorly maintained trees can become liabilities, posing risks to structures, power lines, and people. That’s why regular maintenance is key. Pruning and trimming : Removing dead or overgrown branches improves tree health and reduces the risk of storm damage. Disease and pest management : Early detection and treatment can save a tree from decline and prevent the spread to other plants. Root care and mulching : Healthy roots mean a stable, thriving tree. Proper mulching and soil care support long-term growth.  Hiring a certified arborist or professional tree care service ensures that your trees are not only safe but also optimized for health and longevity. 🏡 A Long-Term Investment Unlike many home improvements that depreciate over time, trees grow in value as they mature. A sapling planted today could become a major asset in a decade, offering shade, beauty, and increased property value for years to come. Moreover, trees contribute to a sense of well-being and connection to nature—qualities that are increasingly important to homebuyers seeking sanctuary in their living spaces. In Conclusion Tree care is more than a landscaping chore—it’s a smart investment in your property’s future. By enhancing curb appeal, reducing energy costs, and increasing market value, well-maintained trees offer both aesthetic and financial rewards. Whether you’re planning to sell your home or simply want to enjoy it more, giving your trees the attention they deserve is a decision that quite literally grows over time.

Trees are more than just beautiful additions to our landscapes—they provide shade, improve air quality, and even boost property value. But like any living organism, trees can suffer from disease, damage, and decline. While some issues are easy to spot, others require a trained eye. Knowing when to call a certified arborist can make the difference between saving a tree and removing it entirely. Here are some key signs that your tree may need professional attention:  1. Visible Dead or Dying Branches One of the most obvious signs of trouble is the presence of dead or dying branches, especially in the upper canopy. These limbs can become brittle and fall unexpectedly, posing a serious safety hazard. If you notice large sections of your tree that are bare or have brown, withered leaves during the growing season, it’s time to call an arborist. 2. Cracks or Splits in the Trunk Deep cracks, vertical splits, or cavities in the trunk can indicate structural weakness. These issues may be caused by storm damage, internal decay, or past pruning mistakes. A compromised trunk can make the tree unstable, increasing the risk of it falling during high winds or heavy snow. 3. Fungal Growth at the Base Mushrooms or conks growing around the base of a tree are often signs of internal rot. While not all fungi are harmful, many indicate that the tree’s root system or lower trunk is decaying. An arborist can assess the extent of the damage and determine whether the tree can be treated or needs to be removed. 4. Leaning or Unstable Posture A tree that suddenly starts leaning or appears to be shifting in the soil may have root damage or poor anchorage. This is especially concerning if the lean is recent or accompanied by cracked soil or exposed roots. A professional can evaluate the tree’s stability and recommend corrective measures, such as cabling or bracing . 5. Excessive Leaf Loss or Discoloration If your tree is losing leaves out of season or the foliage is turning yellow, brown, or spotted, it could be suffering from disease, pest infestation, or environmental stress. While some leaf drop is normal, especially in autumn, sudden or severe changes in foliage health should be investigated. 6. Signs of Pest Infestation Boring insects, such as emerald ash borers or bark beetles, can cause significant damage to trees. Look for small holes in the bark, sawdust-like material at the base, or unusual patterns in the wood. An arborist can identify the pest and recommend treatment options to prevent further harm. 7. Root Problems Roots are the unseen foundation of a tree’s health. Signs of root issues include heaving soil, exposed roots, or a tree that appears to be lifting out of the ground. Construction damage, poor drainage, or compacted soil can all impact root health. A certified arborist can diagnose these problems and suggest solutions to support the tree’s recovery. Why Call an Arborist? Certified arborists are trained in the science of tree care. They can diagnose diseases, assess structural integrity, and recommend safe and effective treatments. Whether it’s pruning, pest control, or tree removal, an arborist has the tools and expertise to handle the job safely and responsibly. Final Thoughts Trees are resilient, but they’re not invincible. Paying attention to the warning signs and acting early can prevent costly damage and preserve the beauty and safety of your landscape. If you notice any of the symptoms above, don’t wait—reach out to a professional arborist and give your tree the care it deserves.
Newer Home With Young Trees
By Trevor Soltys & Paul Kasper June 23, 2025
Becoming a homeowner often comes with a flurry of firsts: first lawn mow, first paint touch-up, first time wondering what in the world that switch in the hallway does. But if your new property includes trees, you’ve also inherited a living, growing legacy. Trees not only boost curb appeal and property value but also provide shade, reduce energy costs, and serve as homes for wildlife. That said, they thrive on care — especially in those early years of homeownership when you're still learning the ropes. Here’s a beginner-friendly guide to keeping your trees healthy, happy, and standing tall for decades to come. 1. Get to Know Your Trees Start by identifying the trees on your property. Each species has its own quirks — from soil preferences and sunlight needs to growth habits and susceptibility to pests. Apps like LeafSnap or PictureThis can help, or consider inviting a local arborist for a quick walkthrough. Knowing what you’re working with is step one toward tailored care. 2. Watering Wisely Many people assume mature trees don’t need extra watering, but during dry spells or droughts, even the hardiest trees can get thirsty. A good rule of thumb: trees need about 10 gallons of water per inch of trunk diameter each week. New trees especially should be watered deeply at the base, encouraging roots to grow down and out rather than staying shallow. 3. Mulch Like a Pro Mulching is one of the easiest ways to protect your tree’s roots, retain moisture, and prevent weeds — but it’s often done incorrectly. Avoid the “mulch volcano” (piling mulch high around the trunk) which can lead to rot. Instead, apply a 2–4 inch layer in a wide circle around the base, keeping it a few inches away from the trunk. 4. Prune with Purpose Pruning helps shape trees, remove dead or diseased limbs, and improve airflow, but it should be done with care. Late winter or early spring is ideal for most species, before new growth begins. Start small: remove any damaged, crossing, or rubbing branches. For anything requiring a ladder or a chainsaw, it’s best to call in a pro. 5. Keep an Eye Out for Trouble Regularly inspect your trees for signs of distress like yellowing leaves, dead branches, mushrooms at the base (a possible sign of root rot), or odd bumps or insect activity. Catching issues early makes treatment easier and more effective. Again, a certified arborist can be a great ally here. 6. Give Trees Their Space Be mindful of nearby construction, lawn equipment, or even overzealous gardening. Tree roots extend far beyond the visible canopy and can be damaged by compacted soil or careless digging. When planting new trees, give them room to grow — both above and below ground. Trees are a long game. They ask for patience and consistency, but the payoff is a home shaded by beauty, character, and living history. With a little guidance, your yard can become a haven not just for you, but for generations of songbirds, squirrels, and future homeowners to come.
