Bay Area: Have Your Trees Evaluated by a Certified Arborist Before Severe Weather Hits

tree evaluation

Severe weather in the Bay Area can hit fast and hard, bringing with it strong winds, heavy rains, and unexpected storms. These conditions can wreak havoc on trees, causing broken branches, uprooting, and even major property damage. And while trees may appear strong, they can have hidden vulnerabilities that make them more susceptible to extreme weather.

This is why tree evaluation is so important. A professional, certified arborist can assess your trees’ overall health and structural integrity, spotting issues that might not be obvious to the untrained eye. By getting an evaluation before storm season, you can prevent potential damage, protect your property, and keep your trees healthy all year long.

What Is a Tree Evaluation?

A tree evaluation is a comprehensive assessment of a tree’s health and structural integrity performed by a certified arborist. The goal is to identify potential risks and weaknesses that could lead to damage, especially during severe weather. Evaluations help tree owners understand the current condition of their trees and offer insight into the best care practices.

During the evaluation, an arborist inspects several key elements:

  • Structural Integrity: Arborists assess the overall strength of the tree, including its trunk, branches, and limb attachments. They look for cracks, weak points, and signs of decay that might cause the tree or branches to fail during high winds or storms.
  • Root Health: A tree’s roots are its foundation. An arborist checks for root damage, poor soil drainage, and signs of root rot or disease. Healthy roots are crucial for stability, especially in saturated soils during the rainy season.
  • Disease and Pest Detection: The arborist will also examine the tree for any signs of disease, pest infestations, or fungal infections, which can weaken the tree over time. Early detection allows for timely intervention, preventing further damage.

The benefits of having an early tree evaluation before severe weather are substantial. It helps you catch issues before they become hazards, reducing the risk of property damage and ensuring the safety of your home and surrounding areas. Additionally, early evaluations allow time for necessary treatments, pruning, or reinforcement, setting your trees up for long-term health and resilience.

Common Tree Hazards in the Bay Area

In the Bay Area, severe weather conditions such as storms, high winds, and heavy rains can expose trees to significant stress, leading to potential failures. Here are some common problems that make trees vulnerable during these weather events:

  • Weak Branches: Over time, branches can become weak due to disease, decay, or poor growth patterns. These weakened limbs are prone to snapping under the pressure of strong winds or heavy rain, posing a risk to property and people.
  • Root Issues Due to Soil Saturation: During heavy rainfall, the soil can become oversaturated, especially in areas with poor drainage. This can weaken a tree’s root system, reducing its ability to anchor the tree and making it more likely to topple in strong winds or storms.
  • Trees Growing Too Close to Structures: Trees planted too close to homes, power lines, or other structures are at high risk during severe weather. Branches can break and damage roofs, windows, or power lines, and a tree with poor structural stability might even fall onto a building.

Vulnerable Tree Species in the Bay Area:

  • Oak Trees: While strong and long-lived, oaks can develop root issues in waterlogged soils and may suffer from limb failure if not regularly pruned.
  • Redwoods: Though typically resilient, young redwoods with shallow root systems may be at risk of toppling in storms, particularly in areas with saturated soils.
  • Eucalyptus Trees: Fast-growing and large, eucalyptus trees are known for shedding limbs during high winds, making them a common hazard in urban areas.

Addressing these hazards through regular tree evaluations can help mitigate the risk of tree failure during severe weather, protecting both your property and the long-term health of your trees.

Why Hire a Certified Arborist?

A certified arborist is a trained professional who specializes in the care and maintenance of trees. They undergo rigorous education and certification processes, often through organizations like the International Society of Arboriculture (ISA). Their qualifications include in-depth knowledge of tree biology, proper pruning techniques, disease identification, and risk management, ensuring that they can accurately assess the health and safety of trees.

Certified arborists use specialized tools and techniques for precise tree evaluation. They may use resistograph drills to assess internal decay or sonic tomography to map a tree’s internal structure without causing harm. Additionally, arborists utilize tools like pole pruners for safe trimming, and root collar excavations to evaluate the health of the root system. These advanced techniques help arborists detect hidden issues that could pose risks during storms or high winds.

Hiring a certified arborist ensures that your trees are evaluated and maintained by a professional who understands the complexities of tree health. They provide accurate, long-term solutions to potential hazards, ensuring both the safety of your property and the health of your trees. This expertise is crucial in preventing accidents, especially in regions like the Bay Area, where severe weather can cause significant tree damage. By hiring a certified arborist, you’re investing in the long-term care of your trees while protecting your home and neighborhood.

When Should You Get a Tree Evaluation?

The best time to schedule a tree evaluation is before the storm season, which typically occurs in late fall or early winter in the Bay Area. This timing allows certified arborists to identify potential hazards, such as weak branches or root issues before severe weather hits. Evaluating your trees ahead of storms reduces the risk of branches breaking or trees toppling during high winds or heavy rain.

However, periodic evaluations throughout the year are also highly beneficial—not just before severe weather. Seasonal changes, such as spring growth or summer droughts, can introduce new stress to trees, and routine assessments help maintain their long-term health. Regular check-ups also ensure that any early signs of disease or structural weakness are caught before they develop into major issues.

There are also clear warning signs that indicate a tree may need immediate attention. These include:

  • Cracks in the trunk: Splits or cracks in the bark can indicate internal decay or structural instability, which increases the risk of tree failure.
  • Leaning trees: If a tree begins to lean noticeably, especially after heavy rainfall, it could signal root instability or soil issues.
  • Dead or decaying branches: Deadwood is more prone to breaking, especially in windy conditions, and can be hazardous to nearby property or people.
  • Mushrooms or fungal growth at the base: This is often a sign of root rot, which can weaken the tree’s foundation.

By addressing these concerns early through a thorough tree evaluation, you can protect your property and ensure the continued health of your trees.

Benefits of Early Tree Evaluation Before Severe Weather

Conducting an early tree evaluation before severe weather hits offers several critical benefits:

1. Preventing Costly Damage to Property

Trees with hidden structural weaknesses—such as decaying limbs or unstable root systems—are highly vulnerable to storm damage. By evaluating trees early, arborists can identify and mitigate these risks, preventing branches from falling or trees from uprooting. Early intervention saves property owners from expensive repairs to homes, vehicles, or nearby structures that could otherwise be damaged by falling debris.

2. Ensuring Safety for Your Home and Neighborhood

Safety is a major concern when it comes to storm-damaged trees. Weak or unstable trees can collapse under pressure, endangering not only your property but also neighboring homes, pedestrians, and power lines. Early tree evaluations allow for preventive measures like pruning or removal of hazardous trees, reducing the likelihood of accidents during storms.

3. Promoting Long-Term Tree Health and Preventing Disease

Evaluating trees before the stress of severe weather ensures early detection of diseases, pest infestations, or decay that might weaken a tree. By addressing these issues promptly, you not only protect the tree from storm damage but also promote its overall health, enabling it to thrive long-term. Preventive care, such as treating root rot or pruning diseased branches, helps trees maintain resilience against future environmental stresses.

By investing in early tree evaluations, you not only protect your property but also contribute to the safety and health of your community.

Prepare Your Trees Now to Avoid Future Damage

Scheduling a tree evaluation or tree risk assessment with a certified arborist before severe weather strikes is one of the best ways to safeguard your property. Early evaluations identify structural weaknesses, disease, or root issues that could lead to serious damage when storms hit. Proactive care helps ensure the safety of your home, your neighborhood, and the long-term health of your trees.

Notable Contenders

The Grantham Oak’s 500-Year Vigil

The Oak of Belton Lane in Britain, also known as the Grantham Oak, whispers tales of a bygone era. Estimated to be half a millennium old, this ancient oak has been a silent spectator to the ever-evolving tapestry of history, earning it nominations for the esteemed Tree of the Year award organized by the Woodland Trust.

Centuries ago, the Grantham Oak underwent a unique form of pruning known as “pollarding,” where the top half of the tree was routinely cut for fodder and firewood. Far from debilitating, this practice has bestowed the oak with a longer lifespan and a silhouette that defies the ordinary, painting a stark contrast against the surrounding woodland.

Fun Fact: This massive tree has a girth of 7.02 meters at its widest - that means it would take over four adults reaching finger-tip to finger-tip to hug this tree.

Sheffield’s Chelsea Road Elm: A Haven for the Rare Butterfly

Competing closely is Sheffield’s Chelsea Road Elm, a symbol of endurance and defiance. Saved from the brink of urban development, this tree unveiled its secret – it was a sanctuary for the rare white-letter hairstreak butterfly. In a harmonious dance of coexistence, the elm became a beacon of biodiversity, demonstrating nature’s ability to thrive amidst concrete and steel.

Survivor of the Epidemic

Remarkably, the Chelsea Road Elm also withstood the devastating Dutch elm disease epidemic that claimed approximately 60 million trees across Britain. Standing tall, it embodies the resilience of nature, a triumphant symphony playing through its leaves in the face of adversity.

The Royal Shelter: Crouch Oak of Addlestone

Draped in regal history is the Crouch Oak of Addlestone, reputed to have provided shelter to none other than Queen Elizabeth I and her entourage during picnics. Just imagine the royal tales whispered beneath its boughs throughout its 800 years of living! 

The Crouch Oak is a survivor of attempted arson in 2007. The significant tree, measuring 18ft in height and 24ft around, has a hollow trunk, within which two separate fires were suspected to have been deliberately started in one night. Responding to the suspicious blazes, Surrey Fire and Rescue Service managed to extinguish the fires, which fortunately only affected the dead wood within the tree. Runnymede Borough Council’s Director of Technical Services, Peter Sims, reassured that the tree seemed to be stable post-incident and there were no current plans to fell it.

Fun Fact: Local lore suggests that the bark of the Crouch Oak held enchanting properties. When boiled down, it was believed to concoct a love potion, adding an element of mystique and allure to this ancient tree.

7 Times When Emergency Tree Removal Is Urgently Necessary

Emergency Tree Removal

We all adore the majesty and beauty of trees, with their robust trunks reaching for the skies and their lush canopies providing shade on a hot summer day. However, there are moments when our beloved natural structures can pose significant threats to our safety and property. Sometimes, the only solution is emergency tree removal.

Emergency Tree Removal: Immediate Situations Requiring Urgent Action

1. Hanging by a Thread: The Leaning Tree 🌳↘️

The first obvious indication that tree removal may be necessary is when a tree starts to lean. This can be the result of soil erosion, root damage, or strong windstorms. If the angle of lean increases rapidly or exceeds 15 degrees, it’s time to call in professionals for an emergency tree removal. No one wants a “leaning tower” in their backyard, especially when it could fall at any moment.

2. A Damaged Lifeline: Compromised Roots 

Roots are a tree’s lifeline. They not only provide stability but also supply essential water and nutrients. However, diseases, insects, or physical damage can weaken these vital structures. Visible roots that appear decayed, soft, or discolored are distress signals that your tree may be in trouble. In such cases, immediate removal is essential to avoid a potential collapse.

3. Fungi at the Base: A Bad Sign 🍄

Fungi, such as mushrooms, thriving at the base of a tree might seem like an enchanting sight out of a fairy tale. However, this is often a sign of internal rot. Fungi can break down and consume the wood, causing the tree to become unstable. If you spot fungi, consider it a red flag and arrange for an emergency tree removal.

4. When Branches Turn Brittle: Deadwood 💀

Deadwood, or dead branches, are a risk waiting to happen. Without life, they can become incredibly brittle and susceptible to breaking, posing a threat to anyone or anything underneath. In the worst case, deadwood can even indicate that the tree is dying. If your tree is littered with deadwood, it’s high time for an emergency tree removal.

5. Hollowed Hearts: Cavities in the Trunk 

A hollow tree trunk might seem intriguing or provide a fun hideaway for small creatures, but it’s a surefire sign of internal decay. A hollow trunk compromises the structural integrity of the tree, making it a potential hazard, especially during high winds or storms.

6. Infected Outcasts: Disease-Ridden Trees 🦠

One more scenario that calls for emergency tree removal is when your tree is diseased. Signs of a sick tree can include discolored leaves, abnormal leaf drop, and unusual growths on the bark. Diseases can rapidly progress, killing the tree and potentially spreading to nearby trees. When a tree shows signs of an aggressive disease, removal is often the only viable solution to protect the rest of your green spaces.

7. An Unplanned Blockade: Obstructive Trees 🚧

At times, trees grow in such a way that they interfere with power lines, obstruct pathways, or infringe on nearby property. A tree’s growth is hard to predict and control, and it can sometimes lead to serious logistical issues or even legal troubles. In such situations, it’s important to opt for an emergency tree removal to mitigate the risk of power outages, blocked routes, and neighborhood disputes.

By the Numbers: The Statistics You Should Know 📊

It’s no secret that trees can pose significant risks when they’re unwell. Let’s look at some startling numbers to illustrate the seriousness of the issue:

These statistics underline why taking action when a tree poses a threat is crucial.

The Green Light for Tree Removal 🚦

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.

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.

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. She determines which issues are urgent or emergent, such as split limbs, and creates a plan of action. Sherri also specializes in tree risk assessments and thrives in the “emergency side” of the field, enjoying the science, adrenaline, and desire to be there for her clients.

Sexy Trees is a family-oriented company, and Sherri felt welcomed with open arms when she joined the team. She loves working here and the ever-changing titles that she holds. With her passion for trees and desire to learn, Sherri takes on every task with the same level of respect and attention. She is also passionate about continued education and knowledge, ensuring that she is always up-to-date with the latest research in arboriculture. She takes pride in being able to find answers to any questions that she may not have the answer to.

Sherri is a mother of three wonderful sons, one of whom is a certified gardener. She is a second-generation San Francisco native who spent summers climbing trees with her dad in Nevada City. As a kid, her dad called her the “goat” after her love of climbing.

Sherri currently resides in Novato with her Husband. When she first moved to Novato, there was a suffering magnolia tree in front of her house that hadn’t been adequately cared for. As she studied arboriculture in school, she started to learn more about tree care, including dehydration, pruning times, and root care. She applied her knowledge to the magnolia tree, and five years later, the tree is gorgeous and thriving. Seeing the results of her work firsthand only reinforces her passion for the field and her desire to help others care for their trees.

Sherri is a knowledgeable arborist who is dedicated to her craft. Her passion for trees and desire to learn continually make her an asset to the Sexy Trees family.

Can You Replant a Christmas Tree?

can you replant a Christmas tree

If you’re like most people, you probably enjoy having a Christmas tree in your home during the holiday season. But what happens to the tree once the holidays are over? Can you replant a Christmas tree and keep it alive, or is it destined for the compost heap? The short answer is yes, you can replant your holiday tree. Whether or not it will thrive in the long run depends on the type of tree, the care you give it, and a pinch of luck. Read on for tips on how to care for your tree after the holiday season. 

Caring For Your Tree Over the Holidays

When the holiday season is over and it’s time to say goodbye to your live Christmas tree, there are a few things you can do to give it the best chance at survival. If you’re planning on replanting your tree, it’s important to keep the roots moist in order to promote new growth and prevent it from drying out. One thing to remember is that heaters are being run during the winter so your tree is more likely to dry out over the holidays. Don’t forget to water it!

Can You Replant a Christmas Tree? Yes!

Now that you know the answer to: “Can you replant a Christmas tree,” what comes next? When it comes time to replant your holiday tree, make sure you choose a spot far enough away from your home that gets plenty of sunlight and has well-drained soil to prevent root rot. Soil that doesn’t drain properly can suffocate a tree’s roots, or lead to fungal growth.

You’ll also want to dig a hole that’s deep enough to fully accommodate the roots of your tree. If you’re not sure how deep to dig, a good rule of thumb is to make the hole twice as wide as the roots of your tree, but no deeper than the root ball to the trunk flare. Make sure the tree sits slightly above the soil grade, too. Another tip is to break up the soil before planting and remove any weeds. You can also mix in some high-quality soil from your local garden store to give your tree the best chance at surviving. 

Common Tree Planting Mistakes

When it comes to replanting a Christmas tree, one of the most common mistakes people make is not properly preparing the planting site. The roots of your tree need room to spread out, so be sure to dig a hole that’s wide enough for it to stretch out. It’s also important to loosen the roots before planting and backfilling it with high-quality soil. This will help the roots establish themselves more quickly, and with less effort. 

Another mistake people make is not watering their new tree regularly, but this is less of a concern in the winter. Live Christmas trees need to be watered frequently, especially during the first few weeks after replanting, but this step won’t be as necessary during the rainy season. Be sure to check the soil around your tree regularly and water it whenever necessary.

Talk to an Arborist Today!

With proper care and a little luck, you can replant your Christmas tree and enjoy it for many years to come. Just remember to keep the roots moist if there isn’t any rain, plant it in a sunny spot, and give it plenty of room to grow. With a little TLC, your holiday tree will be a cherished part of your landscape for years to come.

How Mistletoe Grows & Other Facts About the Poisonous Plant

how mistletoe grows

Are you wondering how mistletoe grows? If you think you’ve spotted it on your property, it’s best to have a trained arborist inspect your trees. Why? Well, mistletoe is actually a parasitic plant that grows and feeds on the branches of trees, so it can do a lot of damage!

Read on to learn more about how mistletoe grows and other interesting facts about this strange plant we’ve come to associate with holiday kisses. 

How to Recognize Mistletoe in Your Trees

It’s easiest to spot this festive tree vampire in the winter when there are fewer leaves to conceal its presence. It looks like a green bundle with rounded leaves and white berries. In fact, mistletoe is an evergreen shrub that steals nutrients and water from host trees. Pay special attention if you have oak, maple or other hardwoods in your yard, as well as pine trees and various other conifers. 

Mistletoe in Your Trees

Blame it on the Birds

Birds are responsible for spreading mistletoe far and wide. The plant produces beautiful, white berries that are poisonous to humans, but a prized snack for our avian friends. The birds eat the berries and excrete the seeds on tree branches, where the mistletoe takes root and begins to grow, tapping into the tree’s branches.

What’s in a Name? 

Mistletoe gets its rather unflattering name from the Anglo-Saxon word misteltan, which means “dung twig.” The plant is also known as mislin-bush, kiss-and-go, and churchman’s greeting. The evergreen was actually venerated in Ancient Greece as a symbol of male virility, and can grow on over a hundred tree species. 

What’s With All the Kissing? 

Mistletoe has long been associated with winter solstice celebrations. Kissing under a sprig of mistletoe was supposed to bring love and luck, and maybe even marriage. Traditionally, after each kiss, a berry was removed until none were left.  

How Mistletoe Grows and Harms Trees

Because mistletoe is a parasitic plant that inserts its roots into the branches of your trees, it’s best to have it professionally removed as soon as possible. The more mistletoe spreads, the harder it becomes to save infected trees. Mistletoe is harmful to the tree it is growing on, as it steals water and nutrients from the host tree. In addition, mistletoe can also harbor insect pests and diseases. If you find mistletoe growing on a tree, it is best to remove it to prevent the infection from spreading. Mistletoe can be especially damaging to trees during droughts. 

All in all, mistletoe can be a serious threat to the health of your trees, so it’s important to have it removed by a professional arborist. Mistletoe can cause damage to the host tree by stunting its growth, too, weakening its structure, and even causing premature death. If you attempt to remove mistletoe yourself, you could cause more harm, despite your good intentions. It can also be dangerous work, since mistletoe can spread high into a tree’s branches, not to mention branches can be much heavier than they appear.

Mistletoe Removal

Now that you know how mistletoe grows, be sure to check out your yard for signs it’s stealing nutrients from your trees.
