Tree Branch Removal: Why, When, and How to Do It Safely

Tree Branch Removal: Why, When, and How to Do It Safely

There’s an old saying: “In nature, nothing is perfect, and everything is perfect.” While the imperfections of nature often add character to our environment, there are times when these imperfections, like overhanging or dead tree branches, can pose serious dangers. Whether you’re an ardent gardener or someone who simply enjoys their backyard, understanding the ins and outs of tree branch removal is essential to ensure the safety and beauty of your haven.

As the seasons change, trees undergo a natural transformation. Leaves fall, new buds emerge, and sometimes branches wither away. It’s a beautiful cycle of life and death, growth and decay. However, while nature has its way of managing these transitions, in our urban and suburban landscapes, a dying or precarious tree branch can be a ticking time bomb. Not only can it ruin the aesthetics of a well-maintained garden, but it can also become a hazard waiting to wreak havoc. 

The solution? Timely and safe tree branch removal.

Why Remove Tree Branches?

Tree branches aren’t just a minor inconvenience; they can pose serious risks.

  1. Safety: Dead or damaged branches can fall unpredictably. This can cause injuries, especially if kids or pets frequent the yard.
  2. Health of the Tree: Removing dead or diseased branches can often help prevent the spread of diseases or pests, ensuring that the tree remains healthy and vibrant.
  3. Aesthetics and Property Value: A well-maintained tree can boost the curb appeal of your property. On the other hand, an unkempt tree can detract from its beauty.
  4. Protection of Property: Falling branches can damage rooftops, vehicles, and power lines. This not only results in hefty repair bills but can be a fire hazard in proximity to electrical lines.

When Should You Remove Tree Branches?

Understanding the timing for branch removal is crucial.

After a Storm

Storms can break branches or make them unstable. After a storm, inspect your trees for any visible damages.

Seasonal Pruning

Some trees benefit from seasonal pruning, usually during late winter or early spring when they’re dormant. For example, oak trees are best pruned in winter to prevent the spread of oak wilt disease.

Spotting Disease or Pests

If you notice branches with signs of disease, such as fungi or unnatural discoloration, or branches that are infested with pests, it might be time for removal.

Overgrowth

If branches are obstructing pathways, views, or even growing too close to the house, they should be considered for removal.

How to Safely Remove Tree Branches

Branch removal isn’t as simple as grabbing a saw and hacking away. There’s an art and a science behind it, and most of the time it’s best to leave it to the professionals.

Tools for the Task

If you opt to DIY, you’ll need the right tools for the job. This includes:

  • Hand pruners for small branches
  • Loppers for branches up to 2 inches in diameter
  • Pruning saws for larger branches
  • Safety gear: gloves, safety goggles, and a hard hat

Proper Cutting Technique

Locate the Branch Collar: This is the swollen area where the branch meets the tree trunk. Always cut just outside this area.

Use the Three-Cut Technique for Large Branches: First, make a small cut on the underside of the branch a few inches away from the trunk. This prevents the bark from tearing.

Next, move a few inches away from the first cut, and cut all the way through the branch from top to bottom.

Lastly, remove the small stub that remains, cutting just outside the branch collar.

Never Top a Tree: This means cutting the main branches off the top of trees. It can lead to decay and unstable new growth.

Safety First!

Always work with a partner. They can help spot any issues and assist if an emergency arises.

Avoid working near power lines. If branches are close to these lines, always call in professionals.

Be cautious with ladders. Make sure they’re on stable ground, and always have someone holding them steady.

The Facts Speak for Themselves

📊During 1992 through 2007, a total of 1,285 workers died while performing tree care and maintenance; 44% were trimming or pruning a tree when fatally injured. 

📊 While trimming might not prolong a tree’s natural life, consistent and correct pruning can address problems that may reduce its lifespan. Enhancing a tree’s structure can lessen the chances of branch damage or tree collapse, which can influence its longevity.

📊 A well-maintained landscape can add up to 20% to a property’s value.

Professionals Do It Best

The DIY spirit is commendable. However, when it comes to tasks like tree pruning and removal, it’s crucial to remember that professionals truly do it best.

Here’s why:

  • Expertise and Knowledge: Professional arborists and tree service providers have undergone extensive training. They can identify different tree species, know the best time to prune each one, and can spot diseases or pest infestations that an untrained eye might miss.
  • Safety: Tree removal or pruning, especially for tall or expansive trees, can be hazardous. Professionals come equipped with the necessary safety gear and tools, ensuring not only their safety but also that of your property.
  • Efficiency: With years of experience under their belt, a professional can complete a tree-related job in a fraction of the time it might take someone inexperienced. This efficiency saves you time and potential frustration.
  • Tools and Equipment: The right tools make all the difference. Professionals have access to high-quality, specialized equipment that can handle any tree job, big or small.
  • Liability: Most professional tree service companies are insured. This means if there’s any accidental damage to your property, you won’t be left footing the bill.
  • Holistic Care: Beyond just cutting branches, professionals offer a holistic approach to tree care. They can advise on fertilization, pest control, and other tree maintenance aspects to ensure your trees remain healthy and vibrant.

Tree branch removal is essential for the safety of your loved ones and the health of your trees. When done correctly, it protects your property and ensures that your trees remain a lasting and beautiful presence in your yard.

If the idea of tree branch removal seems daunting, or you believe you have a particularly challenging branch situation, why not let the experts handle it?

Fighting Back: Effective Control Methods for Elm Leaf Beetles

elm leaf beetles

In the battle against nature’s pests, the mighty elm leaf beetle may seem a formidable opponent. From their distinctive yellow bodies to their voracious appetites, these pests pose a significant threat to the health of your beloved elm trees. But don’t fret just yet. Even when faced with a tough adversary, there’s always a way to fight back. And that’s what we are here to explore—how to effectively control and protect your trees from the infamous elm leaf beetle.

The Siege of the Elm Leaf Beetle 🐞

Let’s paint a picture. It’s a glorious spring day, and you notice your elm tree’s leaves are riddled with small, round holes and yellowing prematurely. To the untrained eye, it might seem as if fall has come too soon. But you know better. These are classic signs of an elm leaf beetle invasion.

Born from clusters of orange or yellow eggs laid on the underside of leaves, the beetle larvae feed voraciously on leaf tissue, leaving a skeletonized pattern. In large numbers, their feeding can cause severe defoliation and, over time, weaken the tree, leaving it vulnerable to diseases and other pests.

Don’t let your trees succumb to this onslaught!

Know Your Foe: Identifying the Elm Leaf Beetle and Differentiating It from Similar Pests in California 🔍

Accurate pest identification is paramount in the battle against infestations. Here, we’ll focus on distinguishing the elm leaf beetle from similar pests found in California. This identification is vital for applying effective control methods. Let’s start with the basics.

Identifying the Elm Leaf Beetle 

The adult elm leaf beetle is approximately 1/4 inch long, possessing a narrow, somewhat oval body. The beetles are typically olive-green to yellow, sporting a black stripe along each side of their wing covers.

Their larvae, which are more destructive than the adults, present a stark contrast. Approximately 1/2 inch long, they range in color from yellow to black, and feature two black stripes along each side of their bodies.

Now, let’s see how to distinguish them from other beetles commonly found in the Golden State.

The Western Sculptured Pine Borer: Metallic Marauder 

The Western Sculptured Pine Borer might be confused with the elm leaf beetle due to its similar size. However, this borer is metallic brown and has a fluted, sculptured appearance on its wing covers. Unlike the elm leaf beetle, this pest targets pine trees, specifically the bark and wood.

The Fuller Rose Beetle: An Unassuming Pests 

The Fuller Rose Beetle could be another beetle mistaken for the elm leaf beetle, particularly in its larval stage. However, the adult Fuller Rose Beetle is a grey-brown weevil and does its damage primarily at night. They are known to chew the edges of leaves of a variety of plants, not just roses.

The Spotted Cucumber Beetle: A Garden’s Nightmare 

The Spotted Cucumber Beetle is another pest that could be confused with the elm leaf beetle. Adults are yellowish-green with black spots, and they are known to affect a wide variety of plants, including cucumbers and other squashes, corn, and roses.

Recognizing the elm leaf beetle among these similar pests is crucial for implementing the most effective control methods. If you’re unsure of the specific pest your trees are facing, it’s always a good idea to seek advice from a pest control expert. They can accurately identify the problem and suggest the most appropriate treatment to safeguard your trees.

Defensive Tactics: Non-Chemical Controls 

Many might be tempted to reach for the strongest, quickest-acting chemical pesticide. But there’s more than one way to fight this battle. Let’s consider non-chemical controls first.

1. Predator Allies 🦉

Nature often provides its own checks and balances. Predators such as birds and parasitic wasps can help to control the elm leaf beetle population. Encouraging these natural predators to reside in your garden or property could be a long-term, sustainable solution.

2. Tree Banding 🌳

Tree banding involves placing a sticky band around the tree’s trunk to prevent adult beetles from climbing to lay eggs. It’s simple, cost-effective, and safe for the environment.

3. Regular Pruning ✂️

Pruning dead branches and removing dead leaves in autumn can minimize the number of sites available for the beetle to overwinter, disrupting their lifecycle.

Fighting Fire with Fire: Chemical Controls 

If non-chemical controls aren’t enough, don’t lose hope. Chemical control options can serve as an effective last line of defense against severe infestations.

  1. Insecticidal Soaps and Oils 🧼

Insecticidal soaps and oils are less harmful to the environment and can effectively control elm leaf beetles, especially in their larval stage.

  1. Systemic Insecticides 💉

In cases of severe infestations, you can drench the soil with systemic insecticides for the tree to absorb. These are taken up by the tree and transported throughout the plant tissues, providing protection from the inside out.

Before applying any chemicals, it’s always essential to consult with a professional to ensure you’re making the most informed and safe decisions for your trees and the surrounding environment.

Stand Your Ground: Elm Leaf Beetle Resistance

Here’s a compelling piece of data: Studies have shown that certain elm tree varieties demonstrate resistance to the elm leaf beetle. According to the University of California Statewide Integrated Pest Management Program, Chinese elm, ‘Drake’ elm, and ‘Pioneer’ elm exhibited lower rates of beetle infestation.

While this method might be a more long-term plan, selecting elm leaf beetle-resistant tree varieties could provide an enduring solution for future generations of elm trees in your landscape.

Victory is Possible: Recap 

The elm leaf beetle might seem like a formidable adversary, but don’t forget—you’re not defenseless in this battle. With a combination of defensive tactics such as predator allies, tree banding, and regular pruning, along with judicious use of chemical controls, victory is possible. And for the long haul, planting elm leaf beetle-resistant varieties can help fortify your landscape for the future.

Always remember, your first line of defense is vigilance. Regularly inspect your trees for signs of infestation. In doing so, you will be better equipped to respond swiftly and decisively, giving your trees the best chance of staying healthy and robust.

Top Tree Care Mistakes to Avoid for a Thriving Landscape

tree care mistakes

Trees are the lifeblood of any landscape, adding beauty, shade, and even increasing property value. But trees – especially young ones – need proper TLC to ensure they remain healthy and vibrant. Many homeowners unknowingly make mistakes that can harm their trees and lead to an unsightly or even dangerous landscape. In this blog post, we will discuss the top tree care mistakes to avoid, so you can maintain a thriving landscape for years to come.

1. Improper Watering Techniques

Overwatering

One of the most common tree care mistakes is overwatering. While it’s essential to keep your trees hydrated, too much water can lead to root rot, bug proliferation, and other diseases. To avoid overwatering, make sure you understand the specific watering needs of each tree species on your property. Generally, trees need about 1 inch of water per week, either from rainfall or supplemental watering. Be sure to water deeply and infrequently, rather than shallow and often, to encourage deep root growth.

🌱Did You Know? A strong, deep root system anchors the tree securely and allows it to access water and nutrients from deeper soil layers, enhancing its ability to withstand environmental stresses such as drought and strong winds.

Underwatering

Just as overwatering can cause problems, so can underwatering. Trees that don’t receive enough water are more susceptible to pests and diseases, and can even die from drought stress. Check your trees’ soil regularly to ensure it’s moist but not waterlogged. If your area is experiencing a dry spell, be sure to provide extra water to your trees, especially during the hot summer months. Using mulch around the base of your trees can help retain moisture and reduce the need for frequent watering.

2. Incorrect Pruning Practices

Over-pruning

Over-pruning is another common tree care mistake. Removing too many branches at once can stress the tree and make it more vulnerable to disease and pests. As a rule of thumb, never remove more than 25% of a tree’s foliage in a single pruning session. Additionally, avoid “topping” or cutting back a tree’s main branches, as this can lead to weak, unstable growth.

Improper Pruning Cuts

Making improper pruning cuts can also harm your trees. When pruning, always cut just outside the branch collar – the slightly swollen area where the branch connects to the trunk. Cutting too close to the trunk can damage the tree’s bark and expose it to infection. Conversely, leaving a large stub can also lead to decay and disease. Remember to use sharp, clean tools when pruning to prevent the spread of disease and to make clean cuts that heal more quickly.

Pruning at the Wrong Time

Timing is important when it comes to tree pruning. Pruning at the wrong time of year can put your trees at risk for disease or hinder their growth. Generally, the best time to prune most trees is during their dormant season, typically late winter or early spring. However, some species may have specific pruning requirements, so be sure to research the best time to prune the trees in your landscape.

3. Neglecting Pest and Disease Control

Ignoring Signs of Pests or Disease

One of the biggest mistakes homeowners make is ignoring signs of pests or disease in their trees. Early detection and intervention are crucial to preventing these issues from becoming severe. Look out for signs like discolored or damaged leaves, oozing sap, and holes or tunnels in the bark. If you notice any of these symptoms, consult a professional arborist for advice on treatment options.

🦟 Did You Know? Pests are harmful to trees as they can damage their leaves, bark, and roots, weakening the tree’s overall health and ability to grow. Furthermore, some pests can transmit diseases or create entry points for pathogens, which can lead to severe infections or even tree death.

Overusing Chemical Treatments

While it’s important to address pest and disease issues, overusing chemical treatments can cause more harm than good. Some chemicals can be harmful to beneficial insects and even the trees themselves. Always follow the recommended dosage and application instructions for any chemical treatment, and consider using organic or natural alternatives when possible. Integrated Pest Management (IPM) strategies, which combine cultural, biological, and chemical methods, can be a more sustainable and effective approach to maintaining tree health.

Not Monitoring for Invasive Species

Invasive pests and diseases significantly damage your trees and the surrounding ecosystem. Stay informed about any invasive species that may be present in your area, and take steps to prevent their introduction and spread. If you suspect an invasive pest or disease is affecting your trees, contact your local extension office or a professional arborist for guidance on appropriate management strategies.

4. Damaging Tree Roots

Compacting Soil Around Trees

Compacted soil around trees can hinder root growth and prevent water and nutrients from reaching the roots. Avoid driving or parking vehicles near your trees, and minimize foot traffic around the root zone. If you suspect your soil is compacted, consider aerating the area to improve air and water penetration. Adding organic matter, such as compost or well-rotted manure, can also help improve soil structure and promote healthy root growth.

Cutting Roots During Construction

Construction projects near trees can inadvertently damage their root systems, leading to tree decline or even death. Before beginning any construction, consult an arborist to determine the best way to protect your trees and their roots during the project. Establishing a tree protection zone around the tree’s critical root zone can help minimize damage during construction.

5. Planting Trees Incorrectly

Planting Too Deep

Planting a tree too deep can lead to a variety of problems, including root girdling, poor nutrient uptake, and increased susceptibility to pests and diseases. When planting a tree, ensure that the root flare – the point where the trunk begins to widen at the base – is visible above the soil line. This will allow for proper root development and promote overall tree health.

Choosing the Wrong Tree for Your Site

Selecting the right tree for your landscape is crucial to its long-term health and success. Consider factors such as the tree’s mature size, growth rate, and environmental requirements when choosing a species to plant. Planting a tree that is not well-suited to your site can lead to a host of problems, including stunted growth, increased susceptibility to pests and diseases, and potential damage to nearby structures as the tree grows.

6. Failing to Protect Your Trees from Wildlife

Damage from Deer and Rodents

Deer and rodents can cause significant damage to your trees, especially during the winter months when food sources are scarce. Protect young trees by installing tree guards or fencing to deter browsing and gnawing. Repellents can also be effective, but may need to be reapplied frequently, especially after rain or snow.

Bird Damage

While birds are generally beneficial to your landscape, some species can cause damage to trees by pecking at the bark or nesting in tree cavities. If bird damage is a concern, try using visual or auditory deterrents to scare them away. Be sure to monitor their effectiveness and adjust your strategy as needed.

By avoiding these common tree care mistakes, you can help ensure that your trees remain healthy, beautiful, and structurally sound for years to come. Remember that proper tree care starts with understanding the specific needs of the trees in your landscape and being proactive in addressing potential problems. 


If you’re unsure about how to care for your trees, consult the professional arborists at Sexy Trees for guidance and assistance. With the right care and attention, your trees can thrive and become an invaluable asset to your property and the environment.

Drippy Nut Disease in Trees: Separating Fact from Fiction

drippy nut disease

Drippy nut disease has garnered its share of attention in recent years, leading to a host of misconceptions and confusion. This peculiarly-named disease can seriously impact the health of your trees, but what’s the real story behind it? Today, we’re setting the record straight by separating fact from fiction. Get ready to learn how to protect your trees! 🌲🛡️

What is Drippy Nut Disease? 

First things first, let’s uncover the basics of this mysterious ailment. Drippy nut disease, also known as phytophthora, is a fungal infection that targets nut-producing trees like pecans, walnuts, and almonds. This disease is caused by the Phytophthora fungus, which invades the roots and bark of trees, leading to symptoms like rotting, oozing sap, and ultimately, the decline of the tree’s health.

The Truth About Transmission 

📣 FACT: Drippy nut disease can spread in multiple ways.

Several factors contribute to the transmission of this disease. Phytophthora fungus thrives in wet and poorly drained soil, so waterlogged areas are the perfect breeding ground for the infection. It can also spread through contaminated tools, plant materials, and even footwear!

🔍 FICTION: Drippy nut disease only affects trees that produce nuts.

While the name might suggest otherwise, drippy nut disease doesn’t just impact nut-producing trees. It can also target fruit-bearing trees like apple, cherry, and peach trees. So, staying vigilant and protecting your entire orchard from this harmful fungus is essential.

Symptoms and Diagnosis 🌡️

Detecting drippy nut disease early can be the key to saving your trees. Keep an eye out for these common symptoms:

  1. Swollen and discolored roots
  2. Oozing sap from the trunk
  3. Yellowing or wilting of leaves
  4. Dieback of branches
  5. Premature nut drop

To diagnose the disease, a professional arborist will usually take samples of the infected tree tissue and conduct lab tests to confirm the presence of Phytophthora fungus.

H3: The Damage Done: A Closer Look at the Impact 🌪️

📣 FACT: Drippy nut disease can have a significant economic impact on the agriculture industry.

When left untreated, this disease can cause tree decline and eventual death. This not only results in a loss of valuable nut and fruit crops but also increases tree removal and replacement costs.

Let’s take a look at some statistics to understand the scale of the problem better:

😱 30-50%: The potential yield loss for infected almond trees

😰 20-40%: Estimated yield loss for infected walnut trees

😨 10-20%: Estimated yield loss for infected pecan trees

🔍 FICTION: Drippy nut disease is untreatable and invariably fatal.

While drippy nut disease can be devastating, it’s not a death sentence for your trees. Early detection and proper management can help control the infection and prevent its spread. In some cases, trees can recover and continue producing healthy crops.

H2: Prevention and Treatment Strategies 🚑

🌱 FACT: Multiple ways exist to manage and prevent drippy nut disease.

To keep your trees healthy and free from drippy nut disease, follow these best practices:

1️⃣ Improve drainage: Since the Phytophthora fungus thrives in wet conditions, improving soil drainage can help prevent the spread of the disease. Consider planting trees on raised beds or installing drainage systems to minimize waterlogging.

2️⃣ Practice good sanitation: Disinfect tools, footwear, and equipment to avoid spreading the disease from one tree to another. Remove and destroy any infected plant material to reduce the risk of contamination.

3️⃣ Apply fungicides: Fungicides can be an effective way to manage drippy nut disease when used correctly. Consult an arborist or agricultural extension agent for guidance on the best fungicides for your specific tree species and how to apply them safely.

4️⃣ Use resistant rootstocks: Planting trees grafted onto rootstocks resistant to Phytophthora can help reduce the risk of infection. Consult with a nursery or tree specialist to determine the best rootstock options for your area.

🔍 FICTION: Once a tree is infected, it must be removed immediately.

In some cases, infected trees can still recover and produce healthy crops with proper management. However, if the disease has progressed significantly, and the tree’s health continues to decline, removal may be the best option to prevent the spread of the infection.

The Takeaway 🎯

Drippy nut disease can pose a real threat to your trees and your wallet, but with a little knowledge and proactive measures, you can keep your trees healthy and productive. Remember to stay vigilant, monitor your trees for signs of infection, and seek professional advice for treatment and prevention strategies. By separating fact from fiction, you can take control and protect your trees from the damaging effects of drippy nut disease.

How to Deal With Foamy Bark Cankers

foamy bark cankers

Foamy bark cankers are a common problem that affects various tree species, including maple, oak, and dogwood. These cankers are caused by a fungal infection that leads to the formation of foam on the bark of the affected trees. If left untreated, foamy bark cankers can significantly damage the tree, leading to stunted growth, dieback, and even death.

However, with the right approach, dealing with foamy bark cankers effectively and saving your trees is possible. In this blog post, we’ll explore the causes and symptoms of foamy bark cankers, as well as provide tips and strategies for managing and preventing this issue from occurring. Whether you’re a homeowner or a professional arborist, the information provided in this article can help you keep your trees healthy and thriving.

How to Identify Various Canker Types

Identifying the type of canker affecting your trees is crucial in developing an effective treatment plan. Different kinds of cankers have unique characteristics that can help you distinguish between them. Here are some common canker types to look out for:

Sunken Cankers

One of the most common types of cankers is the sunken canker. This canker appears as a depression on the tree’s bark and is caused by a fungal infection. Over time, it can lead to dead wood and wood rot.

Blister Cankers

Another type of canker is the blister canker, which appears as a raised, blister-like lesion on the bark. Bacteria cause this type of canker and can lead to the formation of sunken cankers over time.

Target Cankers

A third type of canker is the target canker, which appears as a series of concentric circles on the tree’s bark. Fungal infection also causes this type of canker and can significantly damage the tree’s vascular system.

Foamy Bark Canker

A foamy bark canker is a fungal infection that affects the bark of various tree species, including maple, oak, and dogwood. The condition leads to foam production on the bark, which can be a telltale sign of this type of canker. The foam is caused by the activity of the fungus, which produces gas as it consumes the bark tissue. Foamy bark cankers can cause significant damage to the tree if left untreated, leading to stunted growth, dieback, and even death. It’s essential to promptly identify and address foamy bark cankers to prevent the spread of the fungus and preserve the health of the affected tree.

How and Why Do Foamy Bark Cankers Form? 

The fungus responsible for foamy bark cankers belongs to the genus Geosmithia, and it commonly enters the tree through wounds or cracks in the bark. Once inside the tree, the fungus begins to consume the bark tissue, producing gas as a byproduct of its metabolism. The gas production leads to the formation of foam on the bark, a distinctive symptom of this type of canker.

Foamy bark cankers can form on various tree species, but they are most commonly found on maple, oak, and dogwood trees. The fungus is particularly active during warm and humid weather conditions, which can promote the growth and spread of the infection.

The presence of foamy bark cankers can weaken the tree’s immune system, making it more susceptible to other diseases and pests. As the infection spreads, it can lead to the formation of cankers, dead wood, and wood rot, which can ultimately cause the tree’s decline or death. Therefore, it’s essential to identify and address foamy bark cankers as soon as possible to prevent further damage to the tree.

What to Do If You Identify a Foamy Canker on Your Tree

If you spot a foamy canker on your tree, it’s essential to take prompt action to address the issue and prevent further damage. Here are some steps to follow:

1. Prune the Affected Area

The first step is to prune the affected area of the tree to remove the infected bark and wood. It’s crucial to make the cut at least 4-6 inches below the visible signs of the infection to ensure that you remove all the infected tissue.

2. Sanitize Your Tools

After pruning, it’s important to sanitize your tools to prevent the spread of the fungus to other parts of the tree or other trees in the area. You can use a solution of 10% bleach or 70% alcohol to sanitize your tools.

3. Apply Fungicide

After pruning and sanitizing your tools, you can apply a fungicide to the affected area of the tree. Fungicides containing copper are effective in treating foamy bark cankers. Always follow the manufacturer’s instructions when applying the fungicide.

4. Monitor the Tree

Monitor the tree for any signs of further infection or decline. If you notice any new symptoms, such as cankers, dead wood, or stunted growth, you may need to take further action to address the issue.

5. Consult a Professional

If you’re not comfortable addressing the issue yourself, it’s best to consult with a professional arborist. They can accurately diagnose the problem and provide you with a treatment plan that is tailored to your tree’s specific needs. Remember, early detection and intervention are key to preventing the spread of foamy bark cankers and preserving the health of your trees.

Preventing Cankers

Preventing cankers is an essential part of maintaining the health of your trees. Here are some steps you can take to prevent cankers from forming:

1. Proper Tree Maintenance

Proper tree maintenance is crucial in preventing cankers. Regular pruning can help remove dead or diseased wood and promote healthy growth. Be sure to prune during the dormant season to reduce stress on the tree.

2. Avoid Wounding the Tree

Avoid wounding the tree as much as possible. Cankers often form on trees that have been injured or wounded. Be careful when mowing or using other equipment near the tree to avoid damaging the bark.

3. Practice Good Hygiene

Good hygiene can help prevent the spread of fungal infections that can lead to cankers. Be sure to sanitize your tools between uses to prevent cross-contamination.

4. Manage Stressors

Managing stressors, such as drought or nutrient deficiencies, can help keep your tree healthy and less susceptible to cankers. Proper watering and fertilization can go a long way in preventing stress.

5. Apply Fungicides

Applying fungicides preventively can also help prevent the formation of cankers. Fungicides containing copper are effective in preventing fungal infections. Be sure to follow the manufacturer’s instructions when applying fungicides.

By following these preventive measures, you can help reduce the risk of canker formation and maintain the health and vitality of your trees.

Meet Sherri

Sherri

Meet Sherri, the newest arborist at Sexy Trees. With eight years of experience as an arborist technician apprentice, Journeyman and certified arborist for the City and County of San Francisco, Sherri brings a wealth of knowledge and expertise to her new role. Working for the city, she was the only female in her program and operated under the guidance of her instructor, Alex, who happens to be one of our very own ISA Certified Arborists. Sherri became an arborist technician for the first program to be state-certified. As part of her new role, she climbed trees to prune them and emphasized tree diagnosis. 

Sherri

Sherri’s interest in arboriculture stems from her background in emergency medical services. During her arboriculture studies, she became fascinated by the similarities between the vascular systems of trees and humans. Trees have complex circulatory systems that transport nutrients, water, and other vital substances throughout their structure. They also have specialized cells that perform functions similar to those of human blood cells. This connection between trees and the human body piqued Sherri’s interest – she recognized the importance of understanding how trees function in order to properly care for them and ensure their health and longevity. As she learned more about arboriculture, she became increasingly interested in the science of diagnosis and the art of pruning.

Sherri’s background in emergency services also prepared her well for the fast-paced and sometimes hazardous work of arboriculture. She deeply emphasizes the importance of safety and the need to be prepared for unexpected events. Her experience taught her to be calm and focused in high-pressure situations and to take a systematic approach to problem-solving.

Sherri’s goal is to gain board-certified Master arborist status through the ISA, and she is always seeking new ways to expand her education. As a lead arborist with Sexy Trees, Sherri meets with clients and asks questions regarding their trees, from aesthetic pruning to health issues.

Aphids, Bees, and Other Springtime Pests to Look Out For

springtime pests

Spring is almost here, and with it comes an abundance of new growth and life. However, along with the beauty of spring also comes a host of springtime pests that can cause damage to your trees. As a tree care company, we like to educate our clients about the various pests that can harm trees so that they can take steps to protect them.

In this blog post, we’ll discuss some of the most common springtime pests to look out for and what you can do to prevent them from causing harm to your trees.

Aphids

Aphids are tiny, pear-shaped insects that can be found on the leaves and stems of trees. They are most commonly found on deciduous trees, but can also be found on conifers. Aphids feed on the sap of trees, which can cause the leaves to turn yellow and curl. They can also cause the tree to produce a sticky substance known as honeydew, which can attract other pests and lead to sooty mold growth on the leaves.

Prevention

To prevent aphids from causing damage to your trees, there are a few things you can do. One is to attract beneficial insects to your yard, such as ladybugs and lacewings, which will feed on aphids. Another is to use a strong stream of water to blast the aphids off of the tree, which can be effective for small infestations. For larger infestations, you may need to use a pesticide specifically labeled for aphid control.

Bees

Bees are important pollinators that are vital to the health of our environment. However, they can also be a nuisance when they decide to build a hive in or around your trees. Bees can cause damage to the tree by burrowing into it to create a hive, which can weaken the structure of the tree and make it more susceptible to disease and pests.

Prevention

To prevent bees from building a hive in your tree, there are a few things you can do. One is to keep an eye out for bees that are flying in and out of a hole in the tree. If you notice this, it’s important to call a professional beekeeper to remove the hive as soon as possible. Another is to keep trees trimmed and pruned so that bees do not have a place to build a hive.

Other Springtime Pests

There are a variety of other springtime pests to look out for, such as caterpillars, scale insects, and spider mites. Caterpillars can defoliate a tree and make it more susceptible to disease, while scale insects and spider mites can cause the tree to become stunted and weak.

Prevention

To prevent these pests from causing damage to your trees, it’s important to keep an eye out for any signs of infestation, such as holes in the leaves or discoloration. If you notice any signs of infestation, it’s important to contact a professional tree care company as soon as possible. They can help to identify the pest and determine the best course of action for treatment.

In conclusion, spring is a wonderful time of year for tree growth, but also a time when pests can cause significant damage. By being aware of the most common springtime pests and taking steps to prevent them from causing harm, you can ensure that your trees remain healthy and beautiful all season long.

If you notice any signs of infestation or damage, don’t hesitate to contact a professional tree care company for assistance.

An Arborist’s 10 Best Tips for Controlling Fusarium Wilt

fusarium wilt

Fusarium wilt is a fungal disease that can infect a wide range of trees, including maple, oak, and elm. The fungus attacks the tree’s vascular system, which can cause wilting, yellowing, and eventual death of the tree. It is important to take steps to control this disease to keep your trees healthy and beautiful.

Here are the 10 best tips for controlling Fusarium wilt:

1. Proper Tree Selection

The first step in controlling Fusarium wilt is to select trees that are resistant to the fungus. Some species of trees, such as red maples, are more susceptible to the disease than others, such as sugar maples. When selecting new trees for your property, be sure to choose species that are known to be resistant to Fusarium wilt.

2. Proper Planting Techniques

Proper planting techniques can also help to prevent Fusarium wilt. When planting new trees, make sure to dig a hole that is at least twice as wide as the root ball and just as deep. This will give the roots room to spread out and establish themselves properly. Also, be sure to plant the tree at the same depth it was growing in the nursery.

3. Proper Watering

The fungus thrives in moist soil, so it is important to keep the soil around your trees well-drained. Water your trees deeply and infrequently, rather than shallowly and frequently. Also, make sure not to over-water, as this can lead to waterlogged soil.

4. Proper Pruning

The fungus can enter a tree through wounds, so it is important to minimize the number of wounds on your trees. Prune your trees during the dormant season, when the tree is less susceptible to infection. Also, be sure to sterilize your pruning tools before and after each cut to prevent the spread of the fungus.

5. Proper Fertilization

The fungus can weaken a tree, making it more susceptible to other diseases and pests. Fertilize your trees with a balanced, slow-release fertilizer to promote healthy growth.

6. Mulch

Mulch helps to retain moisture in the soil and suppress weed growth. Use a 2- to 3-inch layer of organic mulch around the base of your trees, being sure to keep it at least 6 inches away from the trunk.

7. Proper Drainage

The fungus thrives in moist soil, so it is important to ensure that the soil around your trees drains well. If you notice that water is pooling around the base of your trees, consider installing drainage systems such as French drains or swales.

8. Crop rotation

Crop rotation is a great way to prevent Fusarium wilt. The fungus can survive in the soil for several years, so rotating crops can help to break the life cycle of the fungus. If you have a vegetable or flower garden, rotate your crops each year to reduce the risk of Fusarium wilt.

9. Remove and destroy infected plants

Another way to prevent Fusarium wilt is to remove and destroy any infected plants. The fungus spreads easily through the soil, so it is important to remove any infected plants as soon as possible. If you notice signs of disease on your trees, contact an arborist for assistance in removing and disposing of the infected plant material.

10. Use fungicides

Finally, you can use fungicides to help control Fusarium wilt. Fungicides are chemicals that can prevent the growth of fungi and other plant diseases. However, it is important to note that fungicides should be used as a last resort, as they can be harmful to plants and the environment if misused. If you do decide to use fungicides, be sure to follow all label instructions carefully.

By following these steps, you can reduce the risk of Fusarium wilt on your trees and help keep them healthy and strong.

5 Biggest Spring Tree Care Mistakes: Plan Ahead This Winter

spring tree care

Spring is around the corner, and before we know it, the trees in our yards will be waking up. But how often do we stop to consider their well-being during winter? Tree care should happen all year round – not just in spring when leaves are budding or summer when they bloom. To keep your trees healthy and happy this coming season (and every season thereafter), make sure you’re paying attention to some common spring tree care mistakes that too many of us unintentionally make; there’s no better time than right now to plan ahead, so let’s dive into the biggest spring tree care mistakes and how you can avoid them!

1. Improper Planting

This tip is a preventative measure and makes all the difference in establishing a strong and healthy tree. When planting a new tree, follow the directions on the label of the specific type of tree you have purchased; each species has unique needs for sunlight, soil, water, and nutrients.

A few major planting mistakes we often see are:

  • Planting too close to buildings or power lines. Trees need room to grow and spread their branches.
  • Planting in an area that receives too much or not enough sunlight, water, and/or nutrients.
  • Failing to consider the future size of the tree when planting. It’s important to know that mature trees can grow to very large sizes and may need more space than what is available right now.
  • Suffocating the trunk flare with soil. This happens when too much soil is placed around the tree’s base.

2. Neglecting Pruning

Pruning is essential for maintaining an attractive and healthy tree. It’s important to remember that trees need to be pruned differently at different stages of their lives; for instance, young trees will require more frequent and lighter pruning than mature trees.

Pruning mistakes we often see include:

  • Using the wrong tools for the job and making improper cuts on branches. This can lead to the death of a branch or even the entire tree.
  • Pruning at the wrong time of year. Many trees should be pruned in late winter or early spring, but certain species may require a different timing for optimal results.
  • Failing to follow up with proper wound treatment. Pruning can leave wounds on trees that are vulnerable to infection and decay. Make sure you seal the wound correctly with a dressing or paint to protect your tree from further damage.

3. Poor Fertilization Practices

Fertilization is vital for providing trees with nutrients that may be missing from their soil, but too much of a good thing can quickly become a bad thing! Fertilizing mistakes we often see include:

  • Applying too much fertilizer, which can burn the tree’s roots and cause poor growth.
  • Using a fertilizer that is not suited for your tree type. Different species require different nutrients at different rates and cycles.
  • Failing to water the tree after fertilizing. Fertilizer should be applied with enough water to ensure that the nutrients make it down to the roots.

4. Improper Watering

Most trees require deep watering regularly, especially during the summer months when there is less rainfall. Common mistakes include:

  • Failing to water deeply enough for an extended period of time. In general, trees should be watered slowly and deeply for at least 30 minutes in order to ensure that the roots are receiving enough water.
  • Watering too much or too little. Too little water can cause stress or death to a tree, while too much can lead to problems such as root rot.
  • Failing to monitor soil moisture. If a tree is in an area that receives regular rainfall, it may not need to be watered at all; the best way to know for sure is to check the soil for signs of dryness before watering your tree.

5. Ignoring Pests and Diseases

Be proactive about checking your trees for pests and diseases. Various diseases and pests can affect trees, so it’s important to take the necessary steps to diagnose and treat any issue properly. Common mistakes include:

  • Failing to identify the pest or disease correctly. Different pests and diseases require different treatments, so it’s important to get an accurate diagnosis before taking action.
  • Misusing pesticides or other treatments. Pesticides and other treatments should be used in accordance with the label, as misusing them can lead to more harm than good.
  • Failing to monitor trees for signs of further damage after treatment. You may need to take additional steps if the problem persists or worsens despite your efforts.

Taking proper care of trees requires knowledge, vigilance, and effort. While these five common spring tree care mistakes are some of the most frequent issues we see, they’re certainly not the only ones. It’s essential to be aware of all potential spring tree care hazards in order to ensure your trees stay healthy and beautiful for years to come!

Getting Ready for Spring: Tree Fertilizing Guide

tree fertilizing

In the midst of rainy days and cold weather, it’s easy to forget that spring is right around the corner. And that means that all the trees in your yard are gearing up for a new season of growth and beauty. While it may not look like much now – just hefty bundles of twigs and branches – what you’re really looking at is a goldmine of potential.

Proper tree fertilizing care can help make sure that your tree turns into its full-fledged former self. But if you don’t know your NPK from your magnesium sulfate, never fear! We put together this helpful guide to walk you through all the basics, so you get the most out of spring with your tree friends!

WHY Fertilize Trees?

Trees need nutrients just like we do to stay healthy and strong. Fertilizing can help replenish the tree’s existing stores of energy, making it easier for your tree to take in water, grow foliage and support its own ecosystem. A good fertilization plan will make sure that your tree gets the nutrients it needs throughout all four seasons.

Trees in the wild almost never show nutrient deficiency symptoms because of both natural nutrient recycling and the fact that plants only grow where they’re best adapted. Landscape plantings, on the other hand, are especially vulnerable to nutrient deficiency because of their artificial environment and the lack of natural nutrient recycling.

WHEN to Fertilize Trees?

Spring is the best time to fertilize your tree. That’s when the tree starts growing new foliage and needs additional energy for photosynthesis. Depending on what type of tree you have, you may want to fertilize twice during spring – once in early spring and again mid-spring.

HOW to Fertilize Trees?

The key to tree fertilizing success is finding the right balance. If you over-fertilize, you may end up burning your tree’s roots and leaves; if you under-fertilize, your tree won’t get enough nutrients. When in doubt, opt for a slow-release fertilizer that gives your tree a steady dose of nutrients throughout the season. If you’re going for liquid fertilizer, make sure to dilute it with water and apply it at least 6 inches away from the tree trunk.

WHAT are the best evidence-based fertilizers?

There are plenty of evidence-based tree fertilizers out there with the right combination of nutrients for your tree needs. A granular tree fertilizer is typically a good choice, as it’s easy to spread and lasts longer. You can also get tree fertilizers that are specially formulated for certain tree types (i.e. evergreens, deciduous trees). Whatever you choose, make sure to read the label and follow the instructions carefully.

Soil pH

Soil pH is measured using a logarithmic scale of 0 to 14, with 7 being neutral. Soils with a pH below 7 are acidic, and those above 7 are alkaline. Adjusting pH levels is important for three reasons:

  1. Specific plants grow best within a certain range of pH
  2. Soil pH affects the availability of both major and minor nutrient elements
  3. Soil pH influences the level of microbial activity in soils

It’s important to test your tree’s soil pH and adjust the levels as needed before fertilizing. Knowing the tree’s optimum nutrient range and soil pH will help you choose a tree fertilizer that best meets its specific needs.

Plant Nutrition

Besides carbon, hydrogen, and oxygen– which come from air and water– plants need 16 other minerals to grow. Of those minerals, nitrogen (N), phosphorus (P), and potassium (K) are required in the largest quantities. These three elements are referred to as macronutrients and are the primary ingredients in tree fertilizers.

Knowing & Using Nutrient Ratios

The ratio of N-P-K in tree fertilizer is an important part of tree nutrition. The ratio should be adjusted based on the tree’s specific needs, as well as the soil type and pH. Generally speaking, a tree fertilizer for deciduous trees should have slightly more nitrogen than phosphorus, while evergreen tree fertilizers should be higher in phosphorus than nitrogen.

Following these tree fertilizing tips can help make sure your tree gets the nutrients it needs for growth and health. With a good tree fertilizer plan and enough patience, you’ll have a thriving tree in no time!To schedule a consultation with an experienced arborist, you can reach us at 925-233-6877 or send an email by clicking here.
