The Atlantic hurricane season is a time when most tropical cyclones are expected to develop across the northern Atlantic Ocean. It is currently defined as the time frame from June 1 through November 30. What plans should prudent consumers take with the trees in their landscape?

Hurricanes and violent storms

“It is important that people who live in the East and Gulf coastal areas be prepared,” says Tchukki Andersen, BCMA, CTSP* and staff arborist with the Tree Care Industry Association. “Even people in the Midwestern states should heed the warning. Right now, get your trees as ready as they can be to survive a major storm. Don’t wait until the storm is headed your way.”

One of the greatest dangers to life and property during hurricanes is posed by falling trees and limbs. “Larger trees in leaf will ‘catch’ more wind and be subjected to increased mechanical stresses. These stresses increase the chances of either branch or whole-tree failure,” explains Andersen. “Preparing trees for a high-wind event should be done well in advance of the storm season. However, it’s not too late to start preparing, now. To help ease these dangers, have a qualified tree care provider evaluate your trees. Doing this will help determine potential weaknesses and dangers.”

Examine your trees for the following danger signs:

  • Wires in contact with tree branches. Trees may become energized when they are contacted by electric wires.
  • Dead or partially attached limbs hung up in the higher branches that could fall and cause damage or injury.
  • Cracked stems and branch unions that could cause catastrophic failure of a tree section.
  • Hollow or decayed areas on the trunk or main limbs, or mushrooms growing from the bark that may indicate a decayed and weakened stem.
  • Peeling bark or gaping wounds in the trunk could also indicate structural weakness.
  • Fallen or uprooted trees putting pressure on other trees beneath them.
  • Tight, V-shaped branch unions, which are much more prone to failure than open, U-shaped unions.
  • Heaving soil at the tree base is a potential indicator of an unsound root system.

A tree is a living, growing, changing thing, and its integrity and stability could change over time. Don’t assume that a tree that has survived nine severe storms will necessarily survive a tenth. Simultaneously, not all large trees are dangerous. Contact your tree care expert for an onsite examination.

“What’s this? Another tree/branch/large shrub in my yard that wasn’t there before the storm? I better gas up my brother’s old chain saw and go cut it up.”

Stop! Just don’t.

Yet another storm has brought distress into your yard in the form of large branches and even entire trees that have broken and fallen into your world view. Before you dig out your brother’s old chain saw, the first question should be, “Am I capable of removing this large tree/limb myself or should I seek professional help?” Major tree-damage cleanup will undoubtedly require the use of a chain saw and climbing equipment. Unless you are experienced in the use of such equipment and comfortable working off the ground, it would be best to have the work performed by a competent professional.

Wind places loads on trees, including trunks, branches and roots, leading to higher stress. The varying lengths and sizes of tree branches tend to dampen the overall effects of wind; however, as wind speeds increase, the loads placed on stress points within the tree increase exponentially. When the loads exceed trunk, branch or root strength, various types of failures occur.

But my brother’s chain saw is right here – it wouldn’t take me long at all!

It might be tempting to get out there with your brother’s old chain saw and do the work yourself. And this is where so many homeowners get into trouble. Run an internet search for videos of “tree cutting gone wrong” to see just what can happen.

I’ve used a chain saw before to cut up an old fence. What could possibly go wrong if I cut up this giant tree branch in my yard?

Professionally trained tree workers have to know what to look out for. Do you?

  • There could be overhead and/or nearby electrical wires that create potential hazards and limit the options for tree cutting. Torn, hanging limbs overhead could make it extremely dangerous to cut downed limbs underneath them.
  • Most chain saw work on large limbs or trees requires the experience of a trained operator to prevent injuries. Wood under tension (one or both ends of the fallen tree or branch pinned under other branches or debris) can have different types of binds at different places. Releasing that tension with chain saw cuts is extremely dangerous and can seriously, or fatally, harm the chain saw operator.
  • Uprooted root plates or root balls are unpredictable. Cutting the trunk of a fallen tree from an uprooted plate releases the pressure holding the root plate. The roots are still anchored and may have enough tension that they will pull the stump and root ball back into the hole. It could suddenly sit back into the root hole, trapping anything nearby underneath it.
  • Slope and uneven footing surfaces are dangerous while operating a chain saw.
  • Watch that bar tip! Cutting branches on the ground can cause you to bury the saw bar in the dirt or hit hidden obstacles, causing chain saw kickback.
  • Many homeowners injured doing their own tree work were working alone at the time, significantly lengthening emergency response time and hospital stays. Always have at least one other person work with you. In case you get trapped or injured, there’s someone to call for help.

Removing large, fallen trees should always be done by an experienced professional.

Will Your Landscape Avoid Storm Damage? https://treecaretips.org/will-your-landscape-avoid-storm-damage/damage-prevention/ https://treecaretips.org/will-your-landscape-avoid-storm-damage/damage-prevention/#comments Wed, 28 Sep 2022 09:00:18 +0000 https://treecaretips.org/?p=2275 Have you ever wondered if the large trees by your house would fall on it during some wind or storm

The post Will Your Landscape Avoid Storm Damage? appeared first on Tree Care Tips.

Have you ever wondered if the large trees by your house would fall on it during some wind or storm event causing storm damage? First, stop worrying. Most trees in residential settings are sound and have many years of healthy life before becoming a hazard to your home. However, if your tree is unsafe, it could be a threat to lives and property. How does a tree become a hazard?

“Many shade and ornamental trees are damaged throughout the year by windstorms, lightning or ice and snow accumulations,” notes Tchukki Andersen, BCMA, CTSP* and staff arborist with the Tree Care Industry Association. “Damage usually consists of a few broken branches. However, more severe damage – such as splitting or pulling apart of branch unions, removal of large areas of bark, twisting and splitting of the trunk or even uprooting – pose possible dangers.”

What types of trees cause the most damage?

A few tree species, including Chinese elm, silver maple, boxelder, and various poplars, have brittle wood that is easily broken. These rapidly growing trees cause a considerable amount of damage to homes, cars, buildings, and utility lines each year. Homeowners should be aware of these characteristics and avoid planting them close to potential targets. If such trees are already growing in these locations, preventive pruning, bracing, or cabling may help reduce storm damage this winter. This is particularly true as the tree grows, and the weight and surface of the leaf and branch area increases.

Over the years, growing trees will add more leaves, become heavier and “catch” more wind, so they are prone to increased mechanical stresses, thus increasing the chances of failure. Larger trees will also affect an increased area should they or their larger limbs fall. This means that homes, other structures, and power lines that might not have been threatened a few years ago might now be under threat by a tree that has grown. Preparing trees to better withstand these natural events is necessary and should be done well in advance of storm season. To help ease these dangers, have a professional arborist evaluate your trees. Doing this will help identify potential weaknesses and dangers.

Look at your trees for the following warning signs:

  • Dead or partially attached limbs hung up in the higher branches that could fall and cause damage or injury
  • Cracked stems and branch forks that could cause catastrophic failure of a tree section
  • Hollow or decayed areas on the trunk or main limbs or mushrooms growing from the bark could indicate a decayed and weakened stem
  • Peeling bark or gaping wounds in the trunk also indicate structural weakness
  • Fallen or uprooted trees putting pressure on other trees beneath them
  • Tight, V-shaped forks, which are much more prone to failure than open U-shaped forks
  • Heaving soil at the tree base is a potential indicator of an unsound root system

Remember, too, that a tree is a living thing and its integrity and stability change over time. Don’t assume that a tree that has survived 10 severe storms will necessarily survive an eleventh.

The Atlantic hurricane season is winding down for 2020, but there is still the potential to do damage through the winter months, and taking damage prevention methods will be needed . Even then, the winter storm season will likely ramp up in a few weeks so, should prudent homeowners still have time to plant storm protection strategies for the trees and shrubs in their landscape?

Hurricanes and violent storms

“It is important that people who live in the East and Gulf coastal areas be prepared for the remainder of the 2020 hurricane season,” says Tchukki Andersen, BCMA, CTSP* and staff arborist with the Tree Care Industry Association. “We’re not quite out of the woods yet. Even people in the Midwestern states should heed the warning. Right now, prepare your strategies to help get your trees as ready as they can be to survive a major storm. Don’t wait until the storm is headed your way.”

Prepare for Hurricane Season in Advance

One of the greatest dangers to life and property during hurricane season is high-wind events posed by falling trees and limbs. “Larger tree leaves catch more wind and can increase mechanical stresses. These stresses increase the chances of either branch or whole-tree failure,” explains Andersen. “Preparing trees for a high-wind event should be done well in advance of the storm season. However, it’s not too late to start preparing, now. As a result, to help ease reduce these dangers, have a qualified tree care provider evaluate your trees. Doing this will help determine potential weaknesses and dangers.”

Look at your trees for the following warning signs:

• Wires in contact with tree branches. Trees energize with electric wires.

• Dead or partially attached limbs hung up in the higher branches that could fall and cause damage or injury.

• Cracked stems and branch unions that could cause catastrophic failure of a tree section.

• Hollow or decayed areas on the trunk  or peeling bark with gaping wounds.

• Fallen or uprooted trees putting pressure on other trees beneath them.

A tree is a living, growing, changing thing, and its integrity and stability could change over time. Don’t assume that a tree that has survived nine severe storms will necessarily survive a tenth. Simultaneously, not all large trees are dangerous. Contact your tree care expert for an onsite examination.

Travel around a neighborhood after a storm and you will see tree limbs, large and small, scattered about the ground. Why do branches fall in your yard from high winds or after ice storms while others merely bend? Should you worry about that large limb overhanging your driveway?

“One reason trees fail is weak branch unions,” says Tchukki Andersen, CTSP, BCMA* and staff arborist with the Tree Care Industry Association. “Homeowners can educate themselves about tree limbs, but they should call a professional arborist if they are worried about an overhanging branch.”

Trees may suffer from naturally formed imperfections. This can lead to branch failure at the union of the branch and main stem. There are two types of imperfections that create weak unions: A branch union with included bark and an epicormic branch.

Branch unions with included bark

Branch unions can be characterized as strong or weak. Strong branch unions have upturned branch bark ridges at branch junctions. Annual rings of wood from the branch grow together with annual rings of wood from the stem. This can create a sound, strong union all the way into the center of the tree.

A weak branch union occurs when a branch and stem (or two or more co-dominant stems) grow so closely together that bark grows between them, inside the tree. The term for bark growing inside the tree is “included bark”. As more and more bark is included inside the tree, the greater the likelihood that this weak union is likely to fail.

In storm-damage surveys conducted by the University of Minnesota’s Forest Resources Department, 21 percent of all landscape trees that failed in windstorms failed at weak branch unions of co-dominant stems. Some species are notorious for having included bark. These species include European mountain ash, green ash, hackberry, boxelder, willow, red maple, silver maple, Amur maple, cherry, Bartlett pear, and little leaf linden.

Epicormic branches

Epicormic branches (also called water sprouts) are formed as a response to poor pruning practices, injury, or environmental stress. These types of branches are new branches that replaced injured, pruned, or declining branches. Commonly, epicormic branches form on the stems and branches of topped trees. When old, large epicormic branches are growing on decaying stems or branches, the epicormics are very likely to fail.

An epicormic branch, by its very nature, forms a weak union.  They have a shallow attachment instead of being attached all the way to the center of the stem. Epicormic branches grow very quickly so they become heavy very quickly. After a time they lose their connection to the main branch. This may cause the branch to fall to the ground because the underlying wood cannot support its weight.

“If a weak union is also cracked, cankered, or decayed, the union is likely to fail, causing the branch to fall off the tree,” says Andersen. “Sometimes, ridges of bark and wood will form on one or both sides of a weakened branch union in order to stabilize the union. The branch is very likely to fail when a crack forms between the ridges.”

Urban trees tend to struggle due to the fact that it is not an ideal growing condition. These trees grow between pavement and buildings and/or in “structurally altered,” disturbed, or compacted soils. Underwatering and overwatering are the most common causes of that struggle for homeowners in these environments.

Water prescriptions are developed to address this problem. But most watering prescriptions don’t consider the efficiency used to water. The most important factor for tree survival actually is the soil moisture, not how much water is dumped onto the rootball.

Watch this video to learn the new methods of stabilizing soil moisture with the use of natural precipitation to help ensure your trees stay strong and healthy no matter what landscape you live in.

Nearly every state has experienced fires that rage out of control in the landscape. While the largest and most devastating burn in the West, fires also spread in the East and South.

house on fireProtect your property in two ways:

  1.  Design and maintain a landscape that discourages fires.
  2.  Build with flame-resistant materials.

“Fires need fuel, such as dead trees, shrubs, and grasses,” says Tchukki Andersen, BCMA, CTSP* and staff arborist with the Tree Care Industry Association (TCIA). “While no landscape is fireproof, there are steps you can take to reduce the danger.”

Tips to combat wildfires:

  • If you are in a wildfire-prone area, reduce the amount of potential fuel around your home. Provide enough tree- and shrub-free space between your home and the undeveloped land. This helps ensure that your home can survive without firefighters.
  • Remove all dead branches hanging over your roof.  Clear leaves, needles, and other dead vegetation on the roof or in gutters.
  • If wildfires are rare but still possible, extend an area of well-irrigated vegetation 30 feet from your home on all sides. In high-hazard areas, clearance of between 50 and 100 feet or more may be necessary – especially on downhill sides of the lot.
  • The lower limbs of tall shade trees should be pruned 6 feet above the ground. A professional arborist should always be contacted to remove any large broken or dead limbs high in the tree. Careful pruning preserves a tree’s appearance, enhances structural integrity, and assists in the plant’s ability to resist fire.

“As a general rule, the healthier the tree, the more likely it is to survive a fire,” explains Andersen. “In addition to pruning, a professional arborist can recommend fertilization, soil management, disease treatment, or pest control measures to promote healthy trees. Landscape design and maintenance are also important factors in a home’s survival.”

Inspection from industry-certified arborists can prevent severe property damage.

Tree failure is a major cause of property damage, especially after high winds. If the wind is strong enough, even healthy trees can be uprooted or broken. However, it might not take a storm or high winds to cause a cracked or rotted tree to fail under its own weight.

Identifying Issues

“Homeowners worried about trees falling and damaging property should call a qualified arborist for an on-site inspection,” advises Tchukki Andersen, BCMA, CTSP* and staff arborist with the Tree Care Industry Association (TCIA). Andersen notes that trees are genetically designed to withstand storms, but all trees can fail – and defective trees fail sooner than healthy trees.

“To a professional arborist,” notes Andersen, “certain defects are indicators that a tree has an increased potential to fail.”

Beware of Cracks

Cracks in tree trunks can be one of the major indicators of an unstable tree. Most cracks are caused by improper closure of wounds or by the splitting of weak branch unions.

They can be found in branches, stems or roots, and vary in type and severity.

The direction of the cracks

There are horizontal and vertical cracks. Horizontal cracks run across the grain of the wood and develop just before the tree fails, making them very difficult to detect. Vertical cracks run with the wood grain along the length of the tree and may appear as shear or ribbed cracks.

Shear Cracks

Shear cracks can run completely through the stem and separate it into two halves. As the tree bends and sways in the wind, one-half of the stem slides over the other, elongating the crack. Eventually, the enlarging crack causes the two halves of the stem to shear apart.

Ribbed Cracks

Ribbed cracks are created as the tree attempts to seal over a wound. Margins of the crack meet and mesh but are reopened due to tree movement or extremely cold temperatures. Thicker annual rings are created in order to stabilize the developing crack at the location of the wound. This forms the ribbed appearance over a period of many years.

These cracks put a tree at high risk of failure and are especially dangerous when combined with other defects or decay.

A qualified arborist can determine the potential for failure by measuring the shell thickness in a few locations around the tree’s circumference, determining the width of the crack opening, and looking for the presence of any other type of defect.

What is the risk?

Cracks are hazardous because they compromise the structure of the tree. They can eventually split the stem in two and are very dangerous when combined with internal decay. The presence of multiple cracks and decay indicates a potentially hazardous tree.

Tree-related wildlife causing damage to tree.

Trees are obviously important to local wildlife, but many arborists and tree-care professionals fail to consider the way their services influence local birds, bugs, and other critters. This not only includes things like the way you decide to prune the trees on a given property, but also the species you recommend clients install.

In some cases, these influences are generally positive – helping wildlife is generally a good thing. But in other cases, supporting local animals can cause headaches for homeowners and property managers. So, consider some of the ways your work will affect local wildlife species and be sure that you aren’t causing problems for your clients down the road.

We’ll talk about three different ways you can help avoid creating these kinds of problems and address existing issues so that your clients can enjoy a harmonious relationship with the local fauna.

Use Discretion When Installing Nut- or Fruit-Bearing Trees

Many beloved tree species – including oaks, apples, and cherries, among others – make excellent additions to client properties. But when installed haphazardly or without forethought, they can cause more problems than they’re worth. Accordingly, you’ll want to be sure to consider the way these edible items will attract wildlife when making recommendations.

But that doesn’t mean these trees should be completely avoided – far from it.

For example, an old white oak growing in the middle of a wide-open lawn may very well attract some squirrels and jays. But because it is growing away from fence lines, bushes, and other sources of cover, the aesthetic and monetary value of the tree may far outweigh the problems caused by a few bushy-tailed rodents.

Conversely, a row of young northern red oaks growing alongside a client’s driveway may cause huge problems. As the trees approach maturity, they’ll begin showering the area with acorns. This will not only attract rodents (and represent potential trip hazards for humans), but the nooks and crannies along the driveway will likely provide cover and shelter for the rodents too.

Allow this to persist for a few years, and your clients will likely need the services of an exterminator. And the exterminator will likely tell them that the trees – which you may have installed – will need to go.

What’s the best way to avoid tree-related issues? Learn more in this blog.

Help Homeowners Keep Tree Limbs Away from Rooflines

Trees don’t only provide food and shelter for wild animals; they also provide travel routes. This is especially true for squirrels, chipmunks, rats, and other rodents, who’ll often use branches to move between trees and your client’s home.

So, if the trees in your client’s yard are providing the local wildlife with easy access to the roof and attic, serious problems are essentially guaranteed. This is particularly true if the offending trees are of the nut- or fruit-producing variety.

Fortunately, addressing this issue is relatively straightforward: Simply recommend that your clients allow you to prune these branches and establish a roughly 10-foot gap around the roofline. Just be sure to plan your pruning cuts carefully and perform them in a manner that won’t cause structural problems for the trees.

As a bonus, keeping tree limbs away from rooflines will also reduce some of the fire-safety concerns that are important in some areas.

Deal with Stumps in a Sensible Manner

Living trees serve as an important resource for wild animals and wildlife, but it is important to note that dead stumps can also be very important for small animals – particularly rodents, snakes and stinging insects. As a tree stump begins to decay and the soil around it begins to soften, animals will often begin making and inhabiting tunnels and burrows in the area. Over time, these stumps can transform into veritable ecosystems and represent a serious threat to the health and safety of your clients.

Unfortunately, there aren’t many hard-and-fast rules regarding the best way to remove stumps to prevent rats and other critters from moving in and setting up shop. You’ll often find that grinding the stump down as flush with the ground as possible is the best plan of action, but at other times, it may be wiser to dig up the bulk of the stump and roots and then pack the area with fill dirt. In other cases, chemically “dissolving” the stump may prove to be the wisest option.

Essentially, you’ll just have to rely on your experience and expertise to decide on a prudent plan.

Final Thoughts

Ultimately, your primary job as a tree-care professional is to maintain your clients’ trees. But, because they are important components of the local habitat, the trees you recommend, prune and service will affect the local critters. And the activities of these animals will in turn affect your clients.

So, be sure to think about how wildlife will interact with the trees on a given property and recommend services that’ll help your clients avoid wildlife-related problems. They’ll appreciate it, which will likely help convince them to retain your services far into the future.

Are your trees drowning? Many parts of the country have experienced a wetter-than-normal fall, which has left many trees sitting in soil saturated with water. Too much water sitting at the base of a tree can cause myriad

problems. A traditional life preserver might not be the answer for these leafy giants, but a little knowledge – and knowing where to seek assistance – can help trees survive

excessive moisture.

Too much water can be as bad for trees as too little water. While some trees are suited to survive occasional floods, most are not. In addition, as a tree becomes older, its ability to adapt to abrupt environmental changes decreases.

“Trees must maintain a proper water balance,” says Tchukki Andersen, BCMA, CTSP* and staff arborist with the Tree Care Industry Association. “Although most trees can withstand moisture conditions from very dry to very wet for short periods of time, continued extremes can cause serious problems, depending on the tree species,” Andersen explains. Some species have adapted to survive drier conditions.

Trees that grow along rivers and trees that grow in or around swamps and ponds can also grow in wet conditions. Flood injury occurs when soil becomes saturated with water. There doesn’t need to be an actual flood to cause flood injury.

Has flooding damaged my trees?

Flood injury is usually expressed through changes in the foliage. One symptom, in particular, chlorosis, is commonly caused by flood injuries. Chlorosis is the yellowing of leaves caused by a decrease in the amount of chlorophyll (green pigment) in the leaves.

This symptom can look like a symptom of a disease but is often caused by non-disease problems, such as excessive water. A professional arborist can determine if chlorosis is caused by a pest, which might be possible to manage, or by water damage.

When flood conditions are prolonged, root dieback occurs. During root dieback, the soil is so saturated that there is not enough oxygen available to the tree roots. Without the proper balance of oxygen and carbon dioxide, roots can’t survive. Eventually, the tree is not able to absorb adequate moisture, despite the flood condition. The tree will exhibit symptoms similar to leaf scorch, where a tree’s leaves turn brown and die due to a lack of moisture in the leaves.

Symptoms of flood injury, in the order that they develop on the foliage, are:

• slight wilting or drooping of the foliage

• yellowing (chlorosis) and browning (necrosis) of leaf edges

• browning in the center of the leaf

The symptoms usually start at the top of the tree or on the ends of branches and spread throughout the entire crown. The symptoms are often more severe on the side of the tree facing the prevailing winds.

What to do

The best prevention for this problem is to avoid planting flood-intolerant trees in areas that are frequently flooded. That’s easy to say after the fact, but in planning a future landscape, this would be the best recourse to avoiding plant damage. There are a variety of wetland trees and shrubs that can tolerate flooding better than other trees.

For those trees in an existing landscape, there are not many practical short-term solutions other than improving drainage. Whenever changes in drainage are made, the impact on all the affected landscape plants needs to be considered. Avoid creating problems for flood-tolerant plants by providing drainage for intolerant plants.

What else can you do?

If you are unsure about your tree’s health, consult a professional arborist who will treat the causes of tree health problems. Contact the Tree Care Industry Association (TCIA), a public and professional resource on trees and arboriculture since 1938. TCIA has more than 2,300 member tree care firms and affiliated companies. All tree care company members recognize stringent safety and performance standards and are required to carry liability and workers’ compensation insurance, where applicable. It has the nation’s only Accreditation program that helps consumers find tree care companies that have been inspected and accredited based on: adherence to industry standards for quality and safety; maintenance of trained, professional staff; and dedication to ethics and quality in business practices.
