A Homeowner’s Guide to Preventing Tree-Related Storm Damage


Severe storms can uproot trees, leave branches strewn across your yard, and threaten the structural integrity of your home. While not all tree-related storm damage can be prevented, homeowners do have options that protect their trees and the buildings on their property.A Homeowner's Guide to Preventing Tree-Related Storm Damage

In this blog, we cover the most common types of storm damage and some of the methods homeowners can use to decrease the risk of storm damage to their trees and storm damage caused by their trees.

Understand the Common Types of Storm Damage

Storms can damage trees in a number of different ways. The most common types of storm damage are as follows:

  • Blow-over. The tree leans heavily to one side or topples over completely.
  • Crown twist. Pressure on an asymmetrical treetop causes branches to split or warp.
  • Branch failure. Branches break away from the tree trunk, falling to the ground or becoming trapped in the foliage.
  • Root failure. Roots fail to anchor into the soil correctly, which may contribute to a potential blow-over.

The type of damage that occurs during a specific storm may depend on the type of tree in question, the condition of the tree, and the severity of the storm. For example, twisted crowns are most likely to happen in gale force winds, while root failure happens most often due to torrential rain.

Preventing Tree-Related Storm Damage

In most cases, preventing storm damage requires consistent effort that begins as soon as a tree is planted. The following measures can diminish the risk of tree-related storm damage.

Consult With an Arborist

When you look out into your yard, you may see a few landscaping changes you want to make. When a professional arborist looks at your yard, he or she can easily identify trees that could sustain or cause serious damage in storm conditions.

As you make a plan to prevent storm damage, consult with an arborist to ensure that your plan is as efficient and complete as possible.

Grow Stronger Trees

If you have young trees on your property, one of the best ways to protect them is to expose them to the local wind environment. Minimize any support system you create so that the tree trunk and roots grow strong enough to easily support the adult tree.

Always remove any needed stakes or supports at the correct time. Leaving these systems in place for too long can stunt the tree’s development and cause weaknesses in the tree trunk.

Keep Trees As Healthy As Possible

When you live in an area with plenty of precipitation, you may leave some of the watering of your trees to Mother Nature. However, regardless of how your trees look at a distance, it’s important to keep tabs on their health and respond whenever an issue arises.

Mulch and water as recommended for each species to keep individual trees and the soil around them healthy. This step helps prevent decay and soil cracking, both of which can lead to uprooting and breakage during storm conditions.

Plant Native Tree Species

When you add to your landscape, plant native tree species as often as possible. These species are better suited to the weather conditions found in your area so they can stay stronger and healthier without as much effort.

Trees native to Illinois include:

  • Beech
  • Birch
  • Elm
  • Maple
  • Willow

As you add new trees to your property, follow all planting recommendations to give your trees the best start possible.

Prune Trees Appropriately

While it’s fairly rare for trees to become upended in routine storms, weak branches can fall off and hit your home due to normal wind conditions. One of the most effective ways to prevent branch loss is to prune your trees.

Cut away any defective or dead branches. If possible, prune these weaker branches before they become more than two inches around.

Additionally, keep the crown of each tree well balanced and eliminate forked branches.

Remove Any Hazardous Trees

Trees that qualify as hazardous need to be removed before storm season or they could fall. You may need to consider removal if the tree exhibits any of the following:

  • Cracks in the trunk, especially vertical cracks
  • Dangerously close proximity to power lines or your home
  • Decay affecting more than half of the tree
  • Deep hollows or holes
  • Leaning trunks, especially if the leaning has exposed roots on one side
  • Numerous dead branches, especially if the branches have a large diameter
  • Pervasive trunk rot, mushrooms, or other fungi

If you suspect that a tree has become hazardous, address your concerns with a professional arborist when he or she evaluates your property. Some conditions, such as common tree diseases, can be corrected with proper care, while others necessitate immediate removal.

As you prepare your home for the next storm season, take these precautions and any others recommended by a professional arborist to protect your property.

Why an Arborist Is Essential for Maintaining a Healthy and Productive Orchard


5ff723e9-0c16-40d6-9102-58be2d1d5ba1Having an orchard is a long-held dream for many people. You may simply want to grow your own fruit for your family’s consumption and to reduce your weekly grocery bill, or you may wish to use it as a small- or large-scale commercial enterprise.

There are many different trees which can make up a fruitful and productive orchard. Apples, peaches, apricots, cherries, citrus varieties, and figs are some of the most popular options. Each of these trees has very individual needs that must be met for it to thrive both in terms of growth and fruit production. Fostering the right environment can be tricky if you’re inexperienced in caring for fruit trees.

Whether you have an existing orchard or you’re planning to plant a new one, employing the services of an experienced arborist is essential to ensure that your fruit trees are healthy and productive. Here are some key areas of fruit tree care that your arborist will be able to help you with.


If you’re starting your orchard from scratch, an arborist can help you make sure your trees start off in optimal conditions. They can tell you which fruit trees will grow within your region and the best location on your property for each tree variety. Factors they will consider include the soil type, drainage, and access to sunlight during the different seasons.

An arborist will also know what the right amount of space required between each tree is, which has a big impact on nutrient availability and ensuring that the trees have enough space once they’ve grown to maturity. They can also provide your young trees with the best start by planting them at the right depth and advising you on their water needs, which are quite specific for young trees.


Annual pruning will assist with the development of your trees and will also control the size of them. It is highly recommended that a professional arborist is employed to prune the trees. Tree pruning can be dangerous, both for the novice pruner and the tree.

Falling tree limbs, even small ones, can cause serious injury if cut incorrectly. Pruning that is too brutal can cause damage to the tree, which may reduce the fruit-bearing capacity as it attempts to heal itself. Too little pruning may result in a tree which becomes misshapen or experiences rangy and inefficient limb growth.

Arborists have all the safety training and equipment to do the job safely and correctly. They will prune the trees to maximize growth and control the size and shape of the tree, and they will know the best season to prune the various trees you have in your orchard.

Fertilization and Soil Care

Like all trees and food producing plants, fruit trees need the right type of nutrients in the right amounts to flourish. The soil quality for each tree is another vital and highly individual element in achieving an ideal environment for tree growth and fruit production. Each variety of tree in your orchard will have its own specific fertilization needs and ideal soil quality, which can be tricky to figure out through trial and error.

An arborist will have the knowledge and experience to establish an optimal feeding, watering, and soil care regimen for your trees. After an initial assessment, you can use their services in a full capacity and have them visit on a regular basis to apply fertilizer and soil products. Or, you can do most of the work yourself and simply have an annual service call to check your trees’ condition and tweak the fertilization and soil care schedule.

Disease and Pest Control

Even the well-cared-for trees can become prey to diseases and pests, which can restrict growth and fruit production, cause severe damage to the tree, and even kill the tree entirely. There are an enormous number of diseases and pests which can be difficult to detect and diagnose without extensive knowledge and expertise.

An arborist is trained in detecting, diagnosing, and treating disease and pest infestation in fruit trees. Regular checks will ensure that pests and diseases are identified and eradicated in their early stages before they can cause any significant and long-term damage.

Receiving the proper care for the fruit trees in your orchard can lead to substantial returns in both fruit production levels and sales of your produce. An orchard with well-maintained fruit trees can also add a considerable amount of value to your property if you decide to sell it in the future.

For these reasons, hiring Smitty’s Tree Service to establish, monitor, and maintain the health of your orchard is a wise and financially sound investment. For further information, contact us to discuss how our years of experience and expertise can help you to get the most out of your existing or planned orchard.

The Science Behind Seasonal Tree Changes


Philosopher and writer Albert Camus once mused, “Autumn is a second spring when every leaf is a flower.” And as you observe the shift from summer to fall around you, it’s hard to ignore the beauty of the vibrant colors that appear on leaves.

What exactly triggers these changes? Discover the scientific explanation for the arboreal autumn transformation below.

Why Leaves Change Colors

Think back to your high school biology class. When you studied plant cells, you learned that they have special organelles, or cell components, that don’t exist in human and animal cells: chloroplasts. Plants use chloroplasts to capture sunlight, mix it with carbon dioxide, and create a special sugar that acts as the plant’s source of food.

Chloroplasts contain high concentrations of a pigment called chlorophyll. Chlorophyll does the work of capturing sunlight. Chlorophyll has a green color because it captures light best from the blue and red portions of the electromagnetic spectrum. Since it reflects green light away, it appears green. Chlorophyll gives most plants their distinctive green hue.

During the summer when plants enjoy many hours of daylight, they can produce plenty of new chlorophyll to replenish any that breaks down. But the shorter days of autumn offer fewer chances to gather sunlight in chlorophyll, meaning the plant has less energy to produce new chlorophyll. As the amount of chlorophyll in leaves drops, other elements inside the leaves become more prominent.

Why Different Colors Emerge

Many non-chlorophyll leaf components aren’t green. As the chlorophyll fades, these other elements get a chance to show their colors:

  • Carotenoids. You probably know carotenoids as the eye-health-promoting chemical in carrots, but they’re also found in many leaves where they create various shades of yellow and orange. Two types of carotenoids exist: carotenes and xanthophylls. Carotenoids are present in the leaf during the growing season, but they aren’t visible because of the presence of chlorophyll.
  • Anthocyanins. Anthocyanins produce reds and purples in leaves and fruits such as plums, apples, and cranberries. These pigments only exist in plant cells during the fall, and they offer some mild protection to the leaves against sunburn and predators.

Which colors emerge on a particular tree depends on several factors:

  • Species. Different trees have varying amounts of carotenoids and anthocyanins in their leaves. The presence or absence of each pigment and the amount of each determines leaf color. Think of the pigments as base paint colors that can be mixed in different combinations to create hundreds of shades.
  • Growing conditions. Vibrant reds are more likely to appear when trees get plenty of bright light during the day but face cold, crisp air at night. This effect is particularly evident in certain maple trees. In contrast, rainy conditions lead to duller leaves. Similarly, sunlight often hits leaves on a single tree in unequal amounts, creating leaves with different shades on the same plant.
  • Absence of pigments. Some leaves have very few pigments other than chlorophyll. When the chlorophyll vanishes, these leaves turn brown quickly before they shrivel up and fall off.

Landscapers and property owners who love the beautiful colors of fall leaves can take these factors into account when they choose which trees to plant.

Why Leaves Fall Off

During the time that leaves change colors, they undergo other changes that are not visible to the naked eye. The veins in the leaf stop distributing nutrients as quickly and completely as they did during the summer. This process is part of the leaf’s death.

At the same time, a layer of cells forms where the leaf connects to the branch. These cells will protect the structure of the tree from the harsh winter conditions, acting almost like a scab over a fresh wound. In the case of trees, however, the scab forms before the leaf falls. As soon as the layer of cells is complete, the leaf will fall off naturally, either due to its own weight or as prompted by the wind.

Why Not All Trees Drop Their Leaves

Despite the overwhelming tendency to shed leaves as winter approaches, not all leafy trees become bare during the coldest months. Some species hold onto their dead, brown leaves all winter long, as if they created a blanket against winter chills. These species include many oaks as well as sycamores and the American beech.

The process behind this leaf retention is known as marcescence. Scientists offer several explanations for why it occurs:

  • Animals may be less like to feed on branches that are still covered in leaves. These leaves protect the plant from losing tender buds that would blossom in the springtime.
  • Trees may have evolved to preserve the nutrients in the leaves for themselves. If they shed them in the spring, those leaves will decay directly into the soil around the tree’s roots. Fall-shed leaves give up some of their nutrients to the environment, not just the tree they fell from.
  • The leaves may offer some protection against the cold temperatures and help the tree retain water.

Most marcescent trees say goodbye to their leaves when temperatures warm up again-they need to make room for new growth. However, in some marcescent trees, the leaves do not even fall off when the weather warms up. Only wind or breaking forces cause the dead leaves to break from their mother trees.


If you love fall leaves, remember to pause and enjoy their vibrant colors before winter arrives. If you have trees that require care or if you’d like to add more trees to your yard, work with the experts at Smitty’s Tree and Arbor Service.

Tapping the Trees: Trees That Produce Maple Syrup


There’s nothing quite like real maple syrup. The sweet, sticky syrup adds a unique flavor to your pancakes and a little sweetness to your baking. And the maple smell seems to hold a reminder of woodlands and fresh, forested trails.

Many may know where pure maple syrup comes from, but what trees produce sap for pure maple syrup? And which yield the best sap? Below, we’ll list several trees that can be tapped for maple syrup and how these trees produce their sap.

Sugar Maples

When producing pure maple syrup, the best sap comes from sugar maples. Out of all the maple trees, sugar maples are one of the two trees that yield the most sap, and compared to other maples, its sap has the highest sugar content and is often clearer than other maple saps. For this reason, sugar maples are the most popular trees to tap for maple syrup.

These trees are mostly found in the northeastern and northcentral states and the surrounding Canadian areas, and they can live for more than 400 years.

Black Maples

Black maples are the second best option for clear, sweet maple sap. This tree can produce just as much sap as its closely related cousin, the sugar maple. However, while black maples yield nicely sweetened sap, the sugar content isn’t quite as high as sugar maple sap.

Black maples are most often found in northeastern states, and their range dips a bit into Canada. While they look very similar to the sugar maple, black maples can be identified by their unique leaves.

Norway Maples

While Norway maples weren’t originally native to the Americas, some can be found scattered through the states. They aren’t a prime choice for tapping, but they do produce some sap. The sugar levels aren’t nearly as high as the sugar maple, so Norway maple syrups won’t have the signature sweetness of pure maple syrup.

Big Tooth Maples

While sugar maples are king when it comes to sugar content, big tooth maple sap has a similar sweetness. These trees can be found in Utah and small areas in Arizona, New Mexico, and Texas, but they don’t produce a ton of sap. So, while they are sweet, tapping big tooth maples takes a little patience as you collect enough sap for syrup.

Silver Maples

If sugar or black maples aren’t available, silver maples are one of the next best choices. The sap has a
slightly less sugar content than sugar maples, so you can still get that delicious flavor from silver maple syrup.  Silver maples don’t produce as much sap as sugar maples, so collecting sap may take a little more time.

And because silver maples bud in the early spring, the sap may not be as clear as other maple saps.
However, these trees can be easily found throughout the eastern states.

Bigleaf Maples

Like many maples, bigleaf maples don’t produce as much or as sweet of sap as the sugar maple. But they do yield enough sweet sap to make a decent syrup for your breakfast table. For the most part, bigleaf maples can be found along the west coast of the states and Canada.

Red Maples

Red maples are similar to silver maples. They bud in the early spring, and because of this, the quality of the sap may not be the best. Red maple sap also isn’t as sweet as the more superior maple saps. And like the silver maples, red maples naturally grow in the eastern states and can still produce some nice sap for maple syrup.


If you’re tapping boxelders for maple sap, you may have to tap more trees to get a reasonable quantity of sap. Boxelders produce about half the amount of sap as sugar maples, so it’s not the best source for pure maple sap. These trees can be found in most of the states but are more concentrated in the eastern half of the country.

How Do Maple Trees Produce Such Sweet Sap?

During the summer, maples trees collect carbohydrates through photosynthesis. When the tree stores these carbohydrates, they accumulate as a starch. This starch eventually transforms into sugar, which combines with the sap.

Sap generally doesn’t flow in the winter, but during the warm daylight hours of spring, sap can easily spill from a tap hole. When it’s colder at night, the tree can draw water and essentially top off its sap levels. Then, as the temperatures rise during the morning and afternoon, the replenished sap can spill into the sap bucket.

Because of this process, the season for tapping is generally six weeks long in the spring. That definitely explains why pure maple syrup can be so expensive.


Trees of all kinds can produce delicious fruit and goods, not just your neighborhood maples. But to maintain that excellent yield of fruits and other produce, you need to keep your trees healthy and strong.

7 Signs Your Tree May Have a Disease


In our previous blog, we provided you with a guide to common tree diseases. But if you’re not sure how to identify a diseased tree, you’re not alone. Most homeowners don’t recognize signs of disease in their trees until they call a specialist.

Do your best to watch for signs of disease in your trees to prevent them from dying and damaging your property. If a dead tree falls onto your home, it could result in costly damages.

Here are some indications that your trees have a disease.

1. Seeping  Fluid

If you notice fluid coming from your tree, it may have alcoholic slime flux. In extreme cases, excess fluid that will pool around the base of the tree. This fluid often has a sour odor and leaves dark streaks down a tree’s bark. Most trees with alcoholic slime flux begin to produce fluid in spring and summer.

2. Hard, Gray Growths

Fomes fomentarius is a fungus that often damages trees like Hickory, Cherry, Maple, and Birch. This fungus appears as a hard, hoof-shaped structure that is a gray color. On the bottom side of the structure, the fungus has millions of white, tiny pores. Once fomes fomentarius attaches to a tree, it will continue to grow until removed.

3. Peeling Bark

Another sign that your tree has a disease is peeling bark. The bark on your tree is important, as it protects the inner core of the trunk and keeps the tree healthy. If the bark on your trees starts to peel, the trees may not maintain necessary nutrients and could die.

Keep in mind that many trees normally experience small amounts of peeling bark. However, if you notice that larger pieces bark are falling from your tree, call a professional arborist for help.

4. Black Flowers or Shoots

A common disease in more than 100 plants is fire blight. When a tree has fire blight, the shoots or flowers on the tree will turn black. Once the shoots and flowers are infected, they will eventually bend into the shape of a shepherd’s crook.

These symptoms typically appear a few weeks after a tree has been infected. Once the disease enters a tree, bacteria populations can double by the hour.

5. Light Brown Shelves near the Base of the Tree

Inonotus dryadeus is a fungus that can cause rotting diseases in trees like Oaks. The fungus stunts branch growth as it infects the tree. Eventually, the fungus reaches the base of the tree and forms large, light brown shelves near the soil. Over time, the light brown shelves harden and turn black.

Infected trees may fall soon after showing obvious symptoms, so you should have the tree removed if you see signs of this fungus.

6. Yellow or Brown Leaves

Yellow or brown leaves coupled with slowed tree growth are often signs of armillaria root rot. You may also notice major branches dying and excessive wilting in trees that have this disease. Fungus in the soil rots and attacks the roots of trees and plants, causing the disease.

Trees with armillaria root rot often take a few seasons to die. However, this process can accelerate if the tree doesn’t receive enough nutrients or has attracted excessive amounts of insects.

7. Powdery Mildew

Another common sign of disease is white, powdery mildew on the leaves of trees. This powdery mildew can develop later in the season when the weather has reached high humidity levels. Along with white mildew, you will likely see a distortion of leaves and stunted tree growth.

In the early stages, powdery mildew starts in small, white spots. These spots will expand and eventually cover the leaf’s surface

If you notice any of these signs, call a professional arborist immediately. Diseased trees should be treated quickly or the tree may die. In addition, always leave disease treatment to professional arborists.
If the wrong treatment is used, you could accidently kill the tree.

Your Go-To Guide for Common Tree Diseases


You work hard to make sure your yard looks clean and beautiful. So when one of your trees struggles, you worry. What caused your tree to become sick, and what can you do about it?

Let’s look at some common tree diseases and how you can treat them.

Alcoholic Slime Flux

Slime flux’s disgusting name fits its unclean appearance. If your tree has a large crack or cavity filled with black, brown, and gray steaks, it may have alcoholic slim flux. While this disease is unwelcome, it is not serious.

Trees it affects: Elm, Fir, Hemlock, Maple, Oak, Sweet-gum, Sycamore, Willow

Cause: The tree must have a crack or cavity in order for alcoholic slime flux to occur. Fungi and bacteria enter the crack and ferment, producing ethanol and gas. When the pressure builds too much, liquid and gas release, and insects are more likely to invade the tree.

Treatment: Unfortunately, you can’t do much to treat alcoholic slime flux. If there is excess fluid on the tree, you can wash it with a soap solution. Do not cut into the wood because this exposes the cavity to oxygen, which welcomes rotting fungi and causes decay.

Armillaria Root Rot

If your tree stops growing and shows wet, white rot, it may have Armillaria Root Rot. Your tree may also show other symptoms as well, like stunted leaves and dying twigs and branches. The tricky part about this disease, however, is that sometimes trees don’t show obvious symptoms.

Trees it affects: Conifers, Hardwoods

Cause: Armillaria Root Rot is not one disease, but a group of diseases caused by Armillaria fungi. The fungi attack the roots and stems and cause the tree to decompose.

Treatment: Professional arborists can treat Armillaria Root Rot in several ways:

  • Improving Tree Strength: Sometimes, Armillaria Root Rot occurs because of prior factors, like insect invasion. Eliminating the insects can decrease disease risk.
  • Inoculum Reduction: If there is a group of infected trees, professionals can remove infected stumps or dill toxic chemicals into the stump to kill the fungi. The roots remaining in the soil shouldn’t be affected.
  • Crop Rotation: Professionals plant trees that resist Armillaria Root Rot. Once the fungi dies out, they can replant the susceptible trees.


Do you see spots or lesions in your tree’s leaves? If so, your tree might have Anthracnose.

Trees it affects: Ash, Dogwood, Oak, Maple, Sycamore, Walnut

Cause: Anthracnose is caused by Anthracnose fungi, which often invade during the spring. The fungi suck nutrients from the plant cells, killing the cells.

Treatment: Anthracnose is not serious, but you’ll want to keep it from spreading to other trees. Good sanitation is the key. Keep trees pruned and spaced far apart and dispose of diseased plant parts.

Bacterial Leaf Scorch

Bacterial Leaf Scorch can occur for a variety of reasons and in a variety of tree species, but it produces similar results: the tissue at the edge of the leaf begins to die.

Trees it affects: Elm, Mulberry, Oak, Red Maple, Sweetgum, Sycamore

Cause: There are several potential causes:

  • Dead roots
  • Leaves losing water too quickly
  • Lack of moisture in the soil
  • Invading fungi or bacteria that block the water source

Treatment: Tree experts can inject an antibiotic called Tetracycline, which may relieve symptoms, but cannot eliminate the disease.

Fire Blight

With Fire Blight, your tree’s flowers and shoots may appear as if something burned them. They could turn dark, shrivel, and droop. A fire doesn’t cause this disease though; a bacteria causes it.

Trees it affects: Apples, Hawthorns, Mountain-Ash, Pears

Cause: The bacteria Erwinia Amylovora can spread in several ways. It can transfer from infected plants to new ones via rain, irrigation water, insects, or even pruning tools.

Treatment: To avoid spreading, you should prune off the infected parts of the tree (about 8 inches from the infection). Just make sure you sanitize your pruning tools so you won’t spread the disease to other trees. Also remove small flowers, which have the highest risk for infection. A tree professional may recommend a bactericide.

Hypoxylon Canker

If your tree is already stressed due to disease or insect invasion, it may develop a secondary disease: Hypoxylon Canker. You’ll notice scorched or wilted foliage, dying branches, and large stromata (masses of fungal tissues) underneath the bark.

Trees it affects: Beech, Birch, Elm, Hickory, Maple, Oak, Sycamore, Walnut

Cause: Tiny fungi spores enter the tree through small openings. When the tree becomes stressed, the infection grows, killing the tree.

Treatment: The best way to stop Hypoxylon Canker involves prevent its invasion in the first place. Make sure to give trees enough water, fertilizer, and mulch—as well as enough room to grow.


If you discover any of these issues with your trees, make sure you talk to a tree and arbor service. They have worked with many tree diseases and can recommend the correct treatment.
