Winter Damage on Trees and Shrubs

Evergreen Trees Covered With Snow

During the winter, trees survive by going into dormancy. This is like hibernation where everything in the system slows down and the tree conserves energy. Yet, trees and shrubs are still susceptible to harsh winter conditions. Freezing temperatures, wind, snow, and salt are some of the culprits of winter damage. Depending on the species and vigor, severe weather can affect bark, moisture, roots, and other vital parts.


While weather is impossible to predict with one hundred percent certainty, it looks like the DC area will see more snow than last year. This will probably be via a series of smaller consistent weather events rather than one huge storm. How your trees and shrubs are affected will depend on not only the amount but the type and timing of winter weather we receive.

For example, wet snow will stay on a tree and adhere to all the surfaces. 1 inch of snow weighs 1 pound per square foot. A typical 30’ to 40’ foot tree has a span of around 900 square feet. 2” of snow multiplied by 900 square feet would give you 1800 pounds.  The weight increases as the amount of snow and the dimensions increase. A typical tree can withstand the normal snow but a tree with defects could pose a problem with the added weight.

Dry snow will not have that adhering effect thus weight is less of an issue. However, the timing of the storm could still have a negative effect. One year, there was an early snowstorm on Halloween. The leaves were still on the tree and could not support the weight of the snow. The tips of the trees broke and trees with poor root systems gave out.

Deciduous Trees

Deciduous trees are large flowering plants with a woody stem that shed their leaves during the fall. Not all species are alike, and some are more susceptible to winter weather than others. Thus, it is important to check the structural integrity of the tree before winter. Flaws could indicate whether a tree will fail or not.

Branch unions play a key role in holding branches together. The added weight of snow and ice could put a problematic tree in quite a predicament. A thicker tree doesn’t allow wind to pass through thus increasing the sway of the tree. A defective tree would therefore be more susceptible to high winds.

Another issue is frost cracks. These are caused by temperatures quickly fluctuating from above to below freezing. The sudden change in temperature causes the outer layer of wood to contract faster than the inner layer. This results in a vertical crack at the weak points of the bark. Sunscald is an elongated canker found along the trunk of thin-barked trees such as beech, dogwood and fruit trees. Sunscald develops often on the south or southwest side of a tree following exposure to the immediate sun. The temperature on the sun side could be as much as 20° higher. The warm temperature causes the tree tissue to become active and break dormancy. When the temperature drops at night, the active tissues are killed, injuring the tree. Further damage can occur because insects and diseases can now enter the tree at the injured location.  This danger continues even into early spring as temperatures continue to fluctuate. Once the tree buds are starting to bloom, a sudden freeze could be problematic with certain species.

Evergreen Trees

Evergreen trees are trees that stay green throughout the year. The winter can prove especially harsh on shrubs due to the thickness of their structure. Ice and heavy snow could break stems with the extra weight. This is especially true with azaleas and boxwoods.

Evergreens tend to have a shallow root system. Trees with a poor root system or a lean will uproot in wet conditions. One species that especially has this problem is the Leyland Cypress. Wind and a poor root system are a deadly combination for this type of tree. That was made abundantly clear by Hurricane Isabel in 2003.Evergreens can also be affected by winter burn. This is the browning or scorching of leaf tips on evergreen foliage in the late winter or early spring. This is attributed to the desiccation or loss of water through leaf transpiration or wind. It then dries out because it lacks moisture. Vigorous or healthy evergreens will re-sprout growth during the spring. It’s important not to prune off the affected areas until it has had time to bounce back. Evergreens could also be affected by snow removal and the salt used on roads. Evergreen ground-covers could also be affected by snow being piled up or the application of salt. Sometimes when snow is on the ground it is hard to tell what’s snow or what’s concrete. Salt could be applied by mistake to a ground-cover. The run-off of that salt and snow can also affect an evergreen if it settles along the base.

Minimizing Winter Damage
Here are some ways to prevent some winter damage to trees and shrubs:

•Water trees and shrubs especially evergreens during dry periods
•Apply anti-desiccant to evergreens to prevent winter burn
•Use wrapping to prevent frost cracks on young trees
•Do not pile snow on evergreens or ground-covers
•If possible, knockoff snow with smaller trees and shrubs
•Remove dead limbs before heavy snow months
•Allow time for trees and shrubs to bounce back

It is important to know that when dealing with something as unpredictable as trees and weather, definitive answers cannot be given. Throughout the years, Arborists have gained experience from prior snowstorms. We understand what trees and defects could be affected by a heavy winter. GV Tree and Landscaping is eager to help you with determining problematic trees and potential issues. Contact us for a free estimate if you have any concerns with landscaping or trees on your property.

Our Company’s Approach to Tree Service Safety

GV Tree Crew working on site

It’s obvious that working in trees is dangerous. Really any activity dealing with heights is risky. Even climbing a 6’ ladder can lead to injuries without the proper safety precautions. The danger increases exponentially when chainsaws, heavy or dead wood, power lines and homes are added.  

We here at GV Tree & Landscaping devote considerable time and effort to the training of our employees. That not only brings us home safe every night, it also improves the quality of our service. We find it paramount to train and retrain all employees in safety protocol. The feeling of accomplishing a nearly impossible task in a safe manner is amazing.

In the past, safe practices were simply learned from more experienced employees. Good and bad practices were passed on from one group to the next. Fortunately, now there is an abundance of safety training material. Safety training now includes videos and seminars. Safety has now become the nature of the industry and those who do not respect it, will suffer.

Personal Protective Equipment (PPE)

The first rule of safety is using personal protective equipment. These are hardhats, rated safety glasses, earplugs, chainsaws chaps and safety vests. With little particles flying everywhere during cutting, safety glasses can save your eyes from tragedy. I can attest that even on the ground, walking into a tree bud can ruin a person’s week.

We also train our employees on road safety and setting up a safe work zone. It is important that signage, cones, and vests meet all industry requirements. We don’t want to see anyone hurt or any property damaged at the end of the day.

Safety for Both Climbers and Grounds Men

In the tree world, we use phrases like ‘baby steps’ and ‘low and slow’ when training new climbers. Before learning to climb, it is necessary to understand the ground operations. On the ground, awareness is key. Both climbers and grounds men are always in constant communication with each other. Climbers check and communicate with the ground crew before dropping branches.

The novice must learn knots before ever stepping foot in a tree. A beginner climber must master the use of a chainsaw and chipper. Then more experienced climbers show beginners how to climb using ropes. Once all these safety methods are internalized and they show promise, we put them up a small tree.

Experience is great, but we also use material that helps us adhere to industry guidelines. These manuals are in both video format and print material in numerous languages. There is no excuse for not having proper safety training. Our experienced climbers retrain by attending safety meetings and seminars. Additionally, trade conventions and climbing competitions provide great learning environments for all skill levels. This is where we learn new techniques and share experiences.

Every quarter we hold aerial rescue training. We place a dummy in the tree and have our climbers rescue it safely. Part of the training is to practice giving the proper information to emergency services. Then we get the climber down without causing more damage. We have never had to perform an aerial rescue, but we are glad that we train for it.

Equipment Safety Training

The equipment we use in the industry can be unforgiving if not used properly. Our experienced employees along with instructional DVDs help train our new employees on the proper use of equipment. When we purchase new equipment, the dealer gives us hands-on training on how to operate it. We not only focus on the use of equipment but also the placement of the equipment on the property.

How Arborists Observe Trees

Trees can make a lovely addition to your landscape, but they often come with their own set of risks. To ensure that your property is safe, personally inspect your trees every year. If you have large trees next to your house, hire an Arborist every two years to perform a site inspection. We also recommend an Arborist inspection before any tree removal or pruning of a tree with questionable health before. This prevents removing a possibly healthy tree or tree pruning that might prove fruitless.

A formal risk assessment, performed by an arborist, is the best way to guarantee your trees are safe. The arborist will check your trees for risk and health. The assessment is based on ANSI A300 Standards, Part 9. During the
assessment, the arborist will observe your trees, identify defects, then judge how likely that defect is to cause tree failure.

Methods of tree assessment:

Light Observation:

This is just a basic overview of your tree and its health. The arborist will observe the tree from all available angles. This includes viewing the tree and the site in relation to any structures. Observing the tree is not as detailed as a tree risk assessment. The perceived risk in relation to any structures is the primary focus with light observation.

Tree Risk Assessment:

This is a detailed assessment of a tree or group of trees. Arborists view soil conditions, growth patterns, soil moisture, wind patterns, and other factors. Using a checklist, an Arborist will note defects in the crown, trunk, roots and any other issues. 

To test the internal wood structure a rubber mallet is often used. A resistograph is also used at times to measure wood density. This tool detects internal cracks, cavities, and decay. It’s done by measuring the density of the tree using a drill bit and electronic sensors. Arborist then form recommendation based on the scientific evidence. 


Lab Testing:

This may include extracting samples for lab analysis. Scientists can test every part of the tree. They can detect fungal growth in stem tissue to root rot in root hairs. They will also perform a soil analysis around the base of the tree.

Documentation:

The cost and depth of documentation will be different from project to project. Projects vary from observing one tree to a group of trees. A report will include recommendations for the mitigation of risk and status of tree health.

Some tree removal and pruning will require permits from the local municipality. When a permit is needed, some form of documentation is often required. If legal documentation is required, consult a certified consulting arborist. This is different from a regular arborist or even a certified arborist. A certified consulting arborist has received specialized training and testing.

Make sure to follow the recommendations made by your arborist or consulting Arborist. Continue to check your trees for future defects throughout the year. Even if your tree appears safe, it’s always best to verify their health especially if the tree is overhanging valuable property.

We here at GV Tree and Landscaping are more than able to handle your regular tree assessment. For any lab testing or documentation, we have a consulting arborist who works with us on a routine basis. We can handle an array of assessments and are ready to take on new projects.

How Tree Services Climb Trees

GV Employee Removing Tree

This has been a popular question from many clients. People often think that we use cherry pickers or ladders and then scurry out on to the limbs like a squirrel. We do walk out onto limbs but it's more controlled than what most people realize.

There are different methods for climbing, but really two primary categories - old school versus new school techniques. Often most climbers use a bit of both. No matter which technique is used, one thing remains the same. You have to get the rope up the tree.  

A Tree Climber ascending up a tree

To do this, we use a thin nylon cord that is very light and attached to a weighted sack. It is thrown into the tree with the goal of hitting above the 'V' or crotch of a sturdy branch that will hold you. Usually a 3-inch diameter branch can hold the weight of a person. However, experienced climbers will use 2-inch diameter branch if the limbs are vigorous. A rope is attached to the cord and then pulled over the branch through the “V”. It is amazing how accurate you can be with a sack and a nylon cord over time.

Old school climbers don't use gadgets when they climb. They use the term, KISS (keep it simple stupid), a timeless classic in the industry. The old school climbers use the end of their rope to tie a knot that holds their weight. Like everything it becomes second nature to them over time.

New climbers are very different. With today's modern advances in technology, climbing equipment has progressed as well. They use tools such as the rope branch, dog bone, and Petzl's mechanical knot. The ropes have gotten thinner and stronger. There has also shift from double to single rope techniques. For assent, a single rope is very efficient and fast but takes time to set up.

Once we are up the tree it’s important to be able to move around quickly and easily. Variables are in play all the time when tree climbing. One has to plan so that time is not wasted. Often our main focus is on how to access all parts of the tree. However, when working on large trees, we divide it into sections and prune one section at a time.

An obvious concern is if the branch will hold your weight. Experience with reason and creativity quells initial fears. When I first started climbing, walking out on limbs was the worst. You get an immediate butterfly feeling in your stomach when you overstep your balance point. Your legs may even shake. I heard it called, 'sewing machine leg'. It's not because you're nervous per se, but rather the angle of your weight. Your mind is not accustomed to climbing angles at first. Eventually after years of repetition, it becomes second nature. 

Proper safety gear is one of the most important aspects of tree climbing. Professional tree services, supervisors and safety training coordinators inspect their crew’s climbing equipment. It is the responsibility of the climber, of course, to inspect their gear daily. Sometimes a solid 3 years will do your gear in and boots will wear out even faster. Boots to a tree guy are like erasers to pencil, they get used.

We check ropes daily for any structural defects. We also review our carabiners for cracks and to make sure that the gate works well. All carabiners used in the industry must be double locking. This prevents the carabiner from accidentally opening and sending you crashing to the ground.

In closing, most tree climbers take extreme care of their climbing equipment. We take pride in our work and we love what we do. Where else can we get amazing views of Washington, D.C. or of Old Town Alexandria.
