The Importance of Using Mulch to Protect Tree Landscaping in Denver

July 12, 2017

Tree trimming and pest management is crucial, but mulch is another one of the most important components of tree landscaping in Denver. Unfortunately, it’s often overlooked by people who don’t understand the many ways that mulch benefits their trees. Why should you apply mulch around your trees? How should you apply it? Here’s what you need to know about using mulch to protect the trees in your yard:

Acts as Insulation

Tree roots are sensitive to temperature changes, and may begin to die off if they are exposed to extremely cold or hot temperatures. However, mulch acts as insulation and protects your tree roots from experiencing fluctuating temperatures. A fresh layer of mulch will keep the soil around your tree’s roots warmer in the winter and cooler in the summer, thus keeping the tree roots healthy and thriving.

Conserves Moisture

Tree roots need water to survive, however they may not be getting enough water if you don’t already have mulch in your yard. Why? Soil heats up when temperatures begin to rise in the summer. At a certain point, temperatures will be high enough to cause evaporation, which means the soil will start to lose its moisture and tree roots won’t get the water that they need to survive. This can be prevented by applying a layer of mulch on top of the soil. The mulch will prevent sunlight from reaching the soil and thus drastically slow down evaporation so the tree roots have more time to absorb moisture before it’s gone.

Lawnmower Protection

If tree roots are exposed or near the surface of the soil, they can easily be damaged by a lawnmower’s blades. Whoever mows your lawn should know that areas with mulch do not need to be mowed, so applying a layer of mulch around your trees should be enough to prevent this problem. But, even if the person who mows your lawn does go over the area, mulch adds another layer of protection and prevents the blades from reaching the roots.

Soil Erosion

Without mulch, soil may begin to erode during a heavy rainstorm. The water can cause the layer of topsoil to break apart and slowly disperse. Since the topsoil contains organic matter that is beneficial to your trees, you should take action to prevent soil erosion. Fortunately, it’s not difficult to do so. Simply apply a layer of mulch around your trees to keep the soil in place so your trees can continue to absorb nutrients.

Reduces Competition

Tree roots compete with other plant roots underground for the nutrients and moisture that they need to survive. If you have recently planted new trees in your yard, it’s imperative that you reduce competition to ensure that the new tree roots receive enough nutrients to grow. To do so, apply a layer of mulch around the base of the tree that is about four inches deep. This is enough to prevent weeds and other unwanted grasses from sprouting up around the tree and competing with its roots for nutrients.


Besides keeping trees healthy, mulch also improves the overall appearance of your tree landscaping. The right type of mulch can make your entire yard look neater, healthier, and more vibrant. In fact, real estate agents often advise sellers to put down a fresh layer of mulch before listing their homes to improve the curb appeal.

How to Apply Mulch Around Trees

As you can see, mulch plays an important role in keeping trees healthy and strong. But, it must be applied properly or your trees won’t reap these rewards. You may think that putting down a layer of mulch is simple, but it’s actually more complicated than it may appear.

First, choose the right type of mulch. There are several different types, but it’s recommended that you stick to hardwood bark, which comes in small or large chips. This type of mulch is safe, attractive, and long lasting, so it’s viewed as one of the best options. If you don’t choose hardwood, the very least you should do is make sure that the type you choose is organic. Organic mulches will break down and provide nutrients to the soil, but inorganic mulches won’t.  

One of the biggest mistakes that you can make with mulch is applying it in the shape of a mound around the base of your tree, so it starts very thick and then becomes thinner as you move further away from the tree. Mulch should not actually come in contact with the base of your tree or it will cause moisture to accumulate on the trunk, which leads to pest infestations. Instead, leave a distance of a few inches between the tree trunk and the mulch. Then, apply the mulch all the way out to the drip line of the branches. The mulch should never be more than four inches deep. Learn more about mulching trees and shrubs.

Once mulch has been applied, make sure you check it frequently to see if it needs to be replenished. Hardwood mulch should only need to be replaced a few times every year, so this isn’t shouldn’t be much of a hassle. You should also check to ensure the mulch has not become matted. If it has, take a rake and gently run it over the mulch, otherwise the roots may be deprived of water and other nutrients.

Many people only use mulch during certain times of the year, but it’s best to use it year-round. Therefore, if you ever remove old mulch from around your trees, be sure to replace it quickly so tree roots don’t have to adjust to new conditions.

Denver Tree Services and What to Know About the Japanese Beetle

June 28, 2017

There are a number of different pests that may harm the trees and shrubs in your lawn, but there are few that are as destructive as the Japanese beetle. This pest originates from Japan, however it has natural predators in Japan that keep the population in check. Unfortunately, these natural predators are not in the U.S., so Japanese beetles are free to destroy greenery. It’s important that you learn about this pest so you know how to spot an infestation and when to call a Denver tree services company for help.

What Does A Japanese Beetle Look Like?

Japanese beetles are very small—around ½ of an inch—but they are brightly colored, which makes them easier to spot despite their size. These bugs have metallic bluish green heads, copper colored bodies, and white hairs on their abdomen. It’s possible that you will spot one of these beetles before seeing any signs of damage, so keep an eye out for bugs that match this description.
Adult beetles lay eggs in the soil that will soon turn into grubs, which are beetles that are still in the larvae stage. Grubs are small and white with six legs and brown bodies. It’s unlikely that you will see them as they stay in the soil over the winter and only emerge when they are adults.

What Plants Do Japanese Beetles Destroy?

It’s estimated that adult Japanese beetles feed off of 300 different kinds of plants, so it’s very likely that you will have at least one plant in your yard that interests these bugs. Some of the most common plants that Japanese beetles feed off of are roses, beans, grapes, and raspberries. However, they also are attracted to black walnut trees, cherry trees, dahlias, elm trees, chestnut trees, and mountain ash trees, among many others.
It may seem like this beetle will eat anything, but that’s not the case. Certain plants, such as dogwood, juniper, green beans, and holly, are not appealing to Japanese beetles. If possible, try to mix these plants into your landscaping so beetles aren’t as attracted to your yard. Learn more about Japanese beetles.

How Can You Spot Damage Caused by Japanese Beetles?

Japanese beetles quickly devour foliage, leaving only skeletonized leaves behind. If you see leaves that just have the veins left, this is a sign that your yard is infested with Japanese beetles. Signs of an infestation will be different if the bugs are attacking the trees in your yard. Trees that have been attacked by these bugs will look almost as if they have been burned by fire.
It’s also common for Japanese beetles to begin at the top of the tree or plant and work their way down to the bottom. Therefore, if you notice damage on the top of your plants, this could be a sign that your plants are currently being attacked by Japanese beetles.
Although adult Japanese beetles begin feeding in June, grubs start to feed on grass roots in the winter.

How to Prevent Japanese Beetle Infestations

There are a few things you can do to prevent Japanese beetles from taking over your yard. As previously mentioned, it helps to place plants that are not attractive to Japanese beetles next to those that are. This may reduce the amount of damage that the beetles do if they do make it to your yard.
If you’ve had a Japanese beetle problem in the past, be proactive by spraying your yard with a solution of two tablespoons of soap diluted in one gallon of water. Do this during the late spring or fall, which is when the beetles are still in the larvae stage.
Pest management experts also recommend keeping your landscaping as healthy as possible to prevent an infestation. This means removing dead or diseased trees and fruits that are ripening prematurely as soon as possible.
Even if you follow all of these steps, it’s still possible for Japanese beetles to creep into your yard. Fortunately, there are ways to control an infestation with the help of a professional.

What Should You Do If You Suspect A Japanese Beetle Infestation?

If you have reason to believe that your yard is being infested by Japanese beetles, contact a tree services company as soon as possible. There are several steps that a professional may follow to remove Japanese beetles from your yard. First, he may remove all of the adult Japanese beetles that he can find by hand and destroy them by placing them in a bucket of warm, soapy water. This is typically done in the early morning when Japanese beetles tend to be the most active. This step of the process is only recommended in cases where the tree service professional suspects that there are not many bugs in your yard yet.
Second, the tree service professional may recommend weeding your yard and keeping it tidy. Japanese beetles are attracted to weeds, so keeping these out of your yard may help with the infestation problem.
Finally, a pesticide will be applied to the areas of your yard that have been affected. The tree service professional may need to use special tools to ensure he has thoroughly sprayed the tops of tall trees that are being destroyed by Japanese beetles. The bugs will make contact with the pesticide when they land on a plant to feed, so this should be effective in destroying large populations of Japanese beetles.
Getting rid of these bugs may seem simple, but it’s no easy feat. Once the bugs have been removed from your yard, it’s possible that they will come back if your neighbor’s yard is also infected. That’s why it’s important to work with a professional who can work one-on-one with you to manage your pest problem.

Tree Services in Denver For the Summer

June 14, 2017

As the seasons change, so do the needs of the trees in your yard. Now that summer is right around the corner, it’s important to learn what tree services in Denver you will need to properly care for your trees. Here’s a look at how you can keep your trees healthy all summer long:

Lay down fresh mulch.

One of the easiest ways to keep your trees healthy during the summer is by putting down a fresh layer of mulch around the bases of the trees. Mulch is important because it prevents weed growth and controls the soil temperature. More importantly, it helps the soil retain water. This means that less water will be lost to evaporation, which becomes very important as the temperatures start to rise. The roots of your trees will be able to absorb water from the soil before it evaporates into thin air if you apply a fresh layer of mulch.
You can find bags of mulch at any hardware or gardening store. There are many different options, but it’s recommended that you look for shredded hardwood mulch. Once you bring the bags home, apply a circle of mulch around the base of the tree. Make sure that the layer of mulch is about three to four inches thick so your trees can reap all of the benefits listed above.

Turn on the sprinklers.

Summer weather can be brutal on trees, especially if they are young or recently planted. It’s estimated that trees need about one inch of water every week, so if you don’t feel your trees are getting this, you may need to water your trees during the summer to keep them healthy.
It’s best to water your lawn in the morning as opposed to the afternoon or evening. In the morning, there usually isn’t any wind to blow away the water droplets before your trees get a chance to absorb them. Temperatures are also cooler in the morning, so you don’t have to worry about the water evaporating before your trees can absorb it. Temperatures are lower in the evening as well, but it’s not wise to water your lawn during this time. If you turn on your sprinklers in the evening, the water that is not absorbed will cling onto your plants and could cause fungus growth. Learn the smarter way to water your lawn.

Look for pest problems.

Many pests, including the magnolia scale, Japanese beetle, and spider mites, are more common in the summer, which means they could slowly begin to infect your trees in the next few months. Get into the habit of frequently inspecting your trees for signs of pest infestations so you can contact a tree service professional as soon as possible.
Of course, you will need to learn the signs of pest infestations if you want to be able to catch them early. Sometimes, you can spot the pests right on your tree. This is true of scale insects, which tend to travel in large packs and leave colorful spots on the barks of trees. You may also notice a sticky substance on your tree or the presence of mold. These are both signs of pest infestations, so if you spot them, contact a tree company within your community right away.

Be prepared for the storms.

Summer is typically a fairly stormy season in Colorado, so it’s smart to work with a tree company to determine if any of your trees need to be trimmed before the storms hit. A tree trimming professional can inspect your trees to identify any weak or dead limbs that need to be removed. He can also ensure that your trees are not leaning too close to your home or any other structure on your property. If you don’t do this, it’s possible that your trees could damage your home or car during a heavy storm with high winds.

Fertilize your trees.

Give your tree fertilizer so it can fight off pest infestations and remain strong during the summer season. There are a few different types of fertilizers, but it’s recommended that you use granulated fertilizer if you are applying it yourself because it’s the easiest one to use. Be sure that you don’t apply the fertilizer on the trunk of the tree. Instead, move about one foot away from the trunk and begin applying the fertilizer on the ground. You should stop once you have reached the area beneath the outermost tips of the tree’s branches.
It’s best to water the area that you just fertilized as soon as you are done. This will ensure that the fertilizer is quickly dissolved so the tree’s roots can absorb the nutrients right away.

Prune your trees.

Most tree trimming does not take place in the summer, but there are a few reasons why you will need to prune your trees during this season. First, pruning can remove any dead or weakened limbs on your trees so they don’t hurt anyone or damage your property if they fall. You will also need to prune any trees that flower during the spring, such as lilacs and magnolias. These trees will need to be pruned in the first part of summer, preferably right after they have finished blooming.
Remember, it’s best to leave pruning up to the professionals instead of trying to handle this task on your own. You will need special equipment so you don’t injure yourself or the tree, and it’s likely that you don’t have the equipment at home. It can also be dangerous to prune large trees if you’re not properly trained to do so. Don’t spend your summer vacation healing from an injury that you sustained while pruning a tree in your yard—let the professionals help.
