The Biggest Mistakes Homeowners Make When Trimming Their Trees

Kelsey T. • September 18, 2020

 Maintaining trees in a way that allows property to be protected is something most homeowners value and do on their own from time to time. Consistent trimming and pruning will allow the tree to live longer by preventing disease caused from dead tree limbs. Continuing to trim improperly will harm the tree more than it will benefit it. This post will go over some of the biggest tree care no-no's that are seen all too often throughout the world. 

Slicing Through the Branch Collar

It is important to outline what the branch collar is before diving into the details. The branch collar is the closest part of the branch that shares itself with the base of the tree. It is composed of vascular tissue which will release sap if it is cut into. The wound caused by it will take a long time to heal and can lead to infection throughout the tree. The reason this mistake occurs so often is because people who try to cut the limbs themselves will often try to cut limb so that it is flush with the trunk of the tree. Doing so will remove or damage the branch collar, causing complications. The best way to trim a tree limb is to leave the branch collar unaltered by leaving at least a one inch nub from the branch and the base of the tree.

Transferring Disease

Like their human counterparts, trees can receive transferable diseases through various forms of bacteria and fungal spores. The most common vehicle that these spores travel on is through un-sanitized sheers used on other trees. A simple method that goes a long way in tree health is to simply disinfect shears between trees. This will kill any unwanted parasites on the blades and keep the disease from transferring. 

On a side note, keeping the foot of the tree clear of any fallen branches, foliage, or debris will also ensure that disease can harbor near the root system. When 
trimming a tree, make sure that the pile of removed limbs are kept away from the root system or completely disposed of. 

Using Unsharpened Shears

Hacking a tree with aged or dull scissors can cause complications down the line for the branch collar. Having to cut multiple times on a branch will take longer for the tree to heal. These serrated wounds will open up an entry point for rot and disease to enter into. If trimming your own trees, invent in a set of lopping shears that sharp enough to chop through branches with ease. Getting old shears sharpened is another option as well. 

Cutting the Wrong Tree Branch

Cutting away to many branches can cause the base to weaken overtime and disform as a result of over-pruning. As a rule of thumb, analyze the tree in question and remove dead or decaying branches before moving onto any other limbs. Branches that form a V-shaped angle are candidates for removal after the dead limbs are removed. From this point, it is important to assess the status of the tree and decide whether or not to continue cutting. If needed, remove smaller branches first before chopping off larger limbs. 

Trimming at an Improper Time or Season


Certain species of trees are best to be left alone as certain times of the year. The bleeding sap from an exposed limb can attract petulant insects which can then spread disease throughout the tree or take it to other trees. This can also cause the bloom of fruit or foliage to be impeded or stopped completely. Late winter is often the best time for trimming for trees to do not bloom. For those that do bloom, it is best practice to wait until the tree has stopped blooming to prune. Throughout the year, dead limbs can be removed whenever they might occur.

A guide to taking care of new trees
By Grant Cool January 24, 2026
Planting a new tree is an act of hope and a wonderful investment in your property’s future. It promises shade on hot summer days, a splash of color in the fall, and a beautiful natural structure for years to come. However, getting that tiny sapling to grow into a mighty, mature tree requires more than just digging a hole and walking away. The first few years of a tree's life are the most critical, and the care it receives during this period will determine its health, strength, and longevity. At Aurora Tree Service, we do more than just remove and prune established trees. We are passionate about helping homeowners cultivate a healthy urban forest, starting with the successful establishment of new trees. We provide the expertise and guidance needed to navigate the crucial first steps of tree care, ensuring your new addition doesn't just survive—it thrives. This guide walks you through the essential steps to properly care for your newly planted tree. The First Few Years: A Critical Establishment Period Think of a newly planted tree as a patient in recovery. It has just undergone the significant stress of being moved from a nursery to your yard. Its root system, which is vital for absorbing water and nutrients, has been drastically reduced. During the first one to three years, the tree's primary focus is not on growing taller, but on re-establishing its root system in the new soil. Proper care during this establishment phase is non-negotiable. Mistakes made now, such as improper watering or neglect, can lead to a weak, stunted tree that is vulnerable to pests, diseases, and storm damage for the rest of its life. Consistent, correct care sets the foundation for a healthy, resilient tree that will add value and beauty to your landscape for decades. Step 1: Watering Wisely Water is the single most important factor for a new tree's survival. However, both too much and too little water can be fatal. The goal is to keep the soil consistently moist but not waterlogged. How Much and How Often? A common mistake is to give the tree light, frequent sprinkles with a hose. This encourages shallow root growth, making the tree less stable and more susceptible to drought. Instead, you need to water deeply and less frequently to encourage roots to grow deeper into the soil in search of moisture. Our Guideline: For the first few weeks after planting, water every 2-3 days. After that, a deep watering once a week is usually sufficient for the first year, unless there is extreme heat or drought. A good rule of thumb is to provide about 10 gallons of water for every inch of the tree's trunk diameter. The Best Method: The most effective way to water is with a slow, steady trickle from a garden hose placed at the base of the tree. Let it run for 20-30 minutes, moving the hose to a different spot around the base halfway through. This allows the water to soak deep into the root zone rather than running off the surface. You can also use a soaker hose or a "gator bag" designed for new trees. How to Check the Soil Don't just guess if your tree needs water. The best way to know for sure is to check the soil. Dig down 2-3 inches with your finger or a small trowel near the base of the tree. If the soil feels dry at that depth, it's time to water. If it feels moist, wait another day or two and check again. Step 2: The Magic of Mulching If watering is the most important step, mulching is a close second. Applying a layer of organic mulch around your new tree is one of the best things you can do for its health. Benefits of Mulch: Conserves Moisture: Mulch acts like a sponge, reducing evaporation from the soil surface and meaning you have to water less often. Regulates Soil Temperature: It keeps the soil cooler in the summer and warmer in the winter, protecting the delicate new roots from extreme temperature swings. Suppresses Weeds: A thick layer of mulch blocks sunlight, preventing weeds and grass from growing and competing with your tree for water and nutrients. Improves Soil Health: As organic mulch (like wood chips or shredded bark) breaks down, it enriches the soil with essential nutrients. How to Mulch Correctly Applying mulch seems simple, but there's a right way and a wrong way. Aurora's Pro Tip: Apply a 2-4 inch layer of mulch in a wide circle around the tree, extending out to the edge of its canopy (the dripline) if possible. The most critical mistake to avoid is "volcano mulching." Never pile mulch directly against the trunk of the tree. This traps moisture against the bark, which can lead to rot, disease, and insect infestations. Always leave a 3-4 inch gap between the mulch and the trunk, creating a donut shape, not a volcano. Step 3: Pruning for Structure, Not Size It can be tempting to start shaping your new tree right away, but for the first year, less is more. The tree needs as many leaves as possible to produce the energy required for root growth. Initial Pruning: When the tree is first planted, the only pruning that should be done is to remove any broken, dead, or crossing branches. Leave the main leader (the central, dominant stem) intact. Structural Pruning: After the first year or two, you can begin light structural pruning. The goal is to establish a strong central leader and well-spaced branches. This is a specialized skill, and improper cuts can do more harm than good. The team at Aurora Tree Service can help you create a long-term pruning plan to ensure your tree develops a strong, safe structure as it matures. Step 4: Protection from Pests and Problems Young trees are vulnerable. Their thin bark and small size make them targets for a variety of threats. Pests and Disease: Keep a close eye on your tree's leaves and bark. Look for signs of trouble like discolored leaves, holes, sticky residue, or unusual growths. Catching a problem early makes it much easier to treat. Animal Damage: Deer, rabbits, and other animals can damage or kill a young tree by rubbing their antlers on the trunk or eating the tender bark and buds. A simple plastic tree guard or a wire cage placed around the trunk can provide effective protection. Weather Protection: In our climate, young trees can be susceptible to "sunscald," where the thin bark on the southwest side of the trunk is damaged by intense winter sun. Using a light-colored tree wrap during the winter months (from November to March) can protect the trunk until the bark thickens.

Too hard to take care of the high maintenance trees
By Grant Cool January 18, 2026
A beautiful, mature tree can be the heart of a landscape. It provides shade, character, and a connection to nature right outside your door. But as trees age, grow, and interact with their environment, they can transform from a cherished asset into a source of constant worry and expense. Many homeowners find themselves wondering: is this tree becoming more trouble than it’s worth? The line between a manageable tree and a high-maintenance problem isn't always clear. It’s easy to overlook gradual changes until a major storm hits or a hefty repair bill arrives. At Aurora Tree Service, our certified arborists specialize in helping you see the complete picture. We provide professional, data-driven assessments that go beyond surface appearances to evaluate a tree’s health, safety, and long-term maintenance demands, empowering you to make the best decision for your property and your budget. The Hidden Costs of a High-Maintenance Tree When we think about tree care costs, we often focus on obvious things like occasional pruning. However, a problematic tree can drain your resources in many other ways. These hidden costs can add up quickly, turning a once-loved tree into a significant financial and emotional burden. A tree that constantly drops large limbs requires frequent, costly cleanups and poses a risk to anything underneath it. A tree with an aggressive root system can crack sidewalks, foundations, and underground pipes, leading to repairs that cost thousands of dollars. Similarly, a diseased tree may require expensive, repeated chemical treatments with no guarantee of success. Ignoring these issues doesn't make them go away; it usually just makes the eventual solution more expensive. How We Identify a Problem Tree Making the decision to remove a tree can be difficult, especially if it holds sentimental value. That’s why a professional evaluation is so critical. Our arborists at Aurora Tree Service use a systematic approach to assess whether a tree’s maintenance needs have become unsustainable. We look at a specific set of factors to provide a clear, unbiased recommendation. 1. Chronic Disease or Pest Infestations Some tree diseases and pests can be managed with a single treatment. Others, however, require a relentless, expensive battle. Conditions like advanced Dutch elm disease, oak wilt, or severe infestations from insects like the emerald ash borer can weaken a tree to the point where it becomes a perpetual patient. Our experts can identify the specific ailment affecting your tree and provide a realistic prognosis. We’ll help you understand the long-term costs of treatment, the likelihood of success, and the risk of the problem spreading to other healthy trees on your property. In many cases, removing a chronically sick tree is the most responsible choice to protect your landscape and your finances. 2. Severe Structural Instability A tree that looks leafy and green from a distance can be dangerously unstable. Structural defects are one of the most serious issues we assess, as they pose a direct threat to your home, vehicles, and family. An arborist from Aurora Tree Service is trained to spot these red flags: Deep Cracks or Cavities: Large splits in the trunk or major branches are clear signs of weakness. We can assess the depth of decay to determine if the tree can still support its own weight. A Sudden or Severe Lean: If a once-upright tree is now leaning, especially if the soil around its base is heaving, it often indicates root failure. This tree is at high risk of toppling over. Included Bark and Weak Unions: When two large branches grow too closely together, they can form a weak, bark-filled union instead of a strong wood connection. These unions are prone to splitting apart during storms. If a tree has significant structural flaws, the cost of trying to save it with cables and bracing can sometimes be more than the cost of removal, without ever fully eliminating the risk. 3. Excessive and Costly Pruning Needs Some trees are simply the wrong species for their location. Fast-growing trees like silver maples or willows planted too close to a house or power lines require constant, aggressive pruning to keep them in check. This isn't just a one-time expense; it's a recurring cost every few years for the life of the tree. Our team can evaluate your tree’s growth habits in relation to its surroundings. We will help you calculate the long-term financial commitment of the required pruning schedule. Sometimes, removing a high-maintenance tree and replacing it with a more suitable, slower-growing species is the smarter financial decision over 10 or 20 years. 4. Interference with Property and Infrastructure A tree’s impact isn't limited to what happens above ground. An aggressive root system is a silent destroyer, capable of causing immense damage to your property’s essential infrastructure. We assess how a tree’s roots are interacting with your home’s foundation, driveway, sidewalks, and underground utility lines. Early signs of root damage, like a small crack in the concrete, can escalate into major structural problems. When a tree’s root system is the source of ongoing property damage, the cost-benefit analysis often tilts heavily in favor of removal. Your Professional Recommendation: Save or Remove? After a thorough evaluation of these factors, our certified arborists at Aurora Tree Service will provide you with a detailed report and a clear, honest recommendation. We don’t just tell you what to do; we explain the "why" behind our advice, presenting you with all the available options. If the tree can be saved with reasonable, cost-effective measures, we will outline a clear treatment or maintenance plan. If, however, the tree’s issues are too severe, its maintenance demands too high, or its risks too great, we will recommend removal. Our goal is to give you the expert information you need to feel confident in your decision, ensuring it aligns with your goals for safety, budget, and peace of mind. Make an Informed Decision for Your Property Living with a high-maintenance, high-risk tree is stressful. You shouldn't have to hold your breath every time the wind blows or worry about the next expensive repair bill. A professional tree assessment from Aurora Tree Service removes the guesswork and anxiety from the equation. Whether you're concerned about a leaning tree, a chronically sick oak, or one that just seems to require endless pruning, our team is here to provide the clarity you need. We'll help you determine if your tree is a sustainable asset or a liability that needs to be addressed. Tired of worrying about a problem tree?

Is a tree worth keeping
By Grant Cool January 9, 2026
A mature tree is more than just a plant in your yard. It’s a landmark, a provider of shade on hot summer days, and often, a silent witness to years of family memories. So, when a tree starts to show signs of decline, or when its branches creep a little too close to the roofline, the decision of whether to keep it or remove it can be surprisingly difficult. Is it an asset or a liability? This decision involves weighing aesthetics, safety, cost, and environmental benefits. It’s a complex calculation where an emotional attachment can easily cloud practical judgment. At Aurora Tree Service, we believe that making the right choice starts with a professional, unbiased evaluation. Our certified arborists are here to help you see the complete picture, providing the expert analysis you need to decide the future of your tree with confidence. When a Tree is an Asset Worth Preserving Before you get out the chainsaw, it’s crucial to recognize the immense value a healthy tree brings to your property. In many cases, saving a tree is not only possible but also the wisest long-term investment. An expert from Aurora Tree Service can help you identify these valuable assets. Contribution to Property Value Well-placed, healthy trees are a major selling point for any home. Studies have consistently shown that mature trees can increase a property's value by 7% to 19%. They enhance curb appeal, create a sense of establishment, and make a property more desirable. A large, beautiful oak or maple in the front yard is a landscape feature that takes decades to replace. Energy Savings and Shade Strategically located trees are nature’s air conditioners. A large deciduous tree on the south or west side of your home can block up to 90% of the intense summer sun, keeping your house cooler and significantly reducing your air conditioning bills. In the winter, the same tree loses its leaves, allowing sunlight to stream in and help warm your home. Environmental and Health Benefits Your trees are hard at work for you and the environment. They improve air quality by absorbing carbon dioxide and other pollutants while releasing oxygen. Their root systems help manage stormwater by reducing runoff and preventing soil erosion. They also provide vital food and shelter for local wildlife, from birds to pollinators. Aesthetic and Sentimental Value Sometimes, a tree's worth can't be measured in dollars. It might be a climbing tree from childhood, a gift from a loved one, or simply the beautiful centerpiece of your garden. If a tree is healthy and structurally sound, preserving this living landmark is often the right choice. Our team can help you find ways to maintain its health, such as corrective pruning or soil treatments, to ensure it remains a safe and cherished part of your landscape. When Removal Becomes the Necessary Choice As much as we love trees, there are times when removal is the only responsible option. An arborist’s job isn't just to save trees, but to identify when a tree has become an unacceptable risk. Ignoring the warning signs can lead to catastrophic damage to your home, property, or even cause serious injury. Significant Disease or Pest Infestation Some tree diseases and pest infestations can be managed, but others are terminal. Conditions like advanced Dutch elm disease, oak wilt, or severe damage from emerald ash borer can weaken a tree beyond recovery. In these cases, removal is often necessary to prevent the disease or pests from spreading to other healthy trees in your yard and the neighborhood. Structural Instability and Compromise This is one of the most critical factors. A tree might look healthy from a distance but be a ticking time bomb. Our arborists at Aurora Tree Service are trained to spot subtle but dangerous structural flaws: Deep Cracks or Splits: Large cracks in the trunk or major limbs indicate a high risk of failure. Hollow Trunk: A significant hollow, often caused by decay, can compromise the tree's entire structure. Heaving Soil or Exposed Roots: If the ground around the base of the tree is lifting, it could mean the root system is failing and the tree is at risk of toppling over. A Sudden Lean: If a tree that once stood straight is now leaning, it’s a red flag for root failure. The Wrong Tree in the Wrong Place Sometimes, a tree is perfectly healthy, but it was simply planted in a poor location. As it grows, it can become a major problem. Interference with Structures: Roots can crack foundations, driveways, and sidewalks. Branches can damage your roof, siding, and gutters. Utility Line Conflicts: A tree growing into power lines is a serious safety hazard that requires professional intervention. In some cases, repeated, aggressive pruning is not a sustainable solution, and removal is the better long-term choice. Overcrowding: When trees are planted too close together, they compete for light and resources, leading to poor health for all of them. Selective removal can allow the remaining trees to thrive. How Aurora Tree Service Helps You Decide Making this call on your own can be overwhelming. Is that crack serious? Is the lean getting worse? Our certified arborists provide a comprehensive tree risk assessment that takes the guesswork out of the equation. Our process involves: A Visual Inspection: We examine the tree from the roots to the crown, looking for signs of disease, pests, and structural defects. Site Evaluation: We assess the tree’s location, paying close attention to nearby targets like your house, power lines, or play areas. In-Depth Analysis: We might use specialized tools like a rubber mallet to sound the trunk for decay or a resistograph to measure the extent of internal rot. A Clear Recommendation: Based on our findings, we provide you with a detailed report and a clear, honest recommendation. We will tell you if the tree can be saved through pruning, cabling, or treatment, or if the risk is too high and removal is the safest course of action. Making the Right Choice for Your Property The decision to keep or remove a tree is a significant one. It impacts your property’s safety, value, and beauty. Don't leave it to chance. With a professional evaluation from Aurora Tree Service, you can be confident that you are making an informed, responsible decision that is best for your home and family.
