Denver Landscaping Companies Share Tips for Successfully Watering Your Trees

April 18, 2018

Your landscaping is the first thing people notice about your property. When it’s properly maintained and your trees look their best, people can’t help but be impressed. However, like your grass and flowers, your trees need regular watering in order to produce the shade and new growth you want to see. If you’re like most homeowners, understanding how to properly care for and water your trees can seem like a bit of a mystery. Here are a few tips from your trusted Denver tree service to ensure that your trees get the care and attention they need to thrive.

Consider the Age of Your Trees

Older trees are more established in your yard and are often more tolerant to changing soil or weather conditions. This means they’ll need less water than newly planted trees in order to produce the same amount of growth each year. With newly planted trees, you’ll want to water around the roots frequently to keep the soil moist and help the roots spread throughout the yard. The more the roots can grow, the more nutrients the tree will receive. Keep in mind that you’ll need to avoid overwatering the trees as too much moisture can lead to root rot and mold growth, destroying what should otherwise be a healthy plant.

Keep an Eye on the Weather

Late winter and early spring can be volatile along the Front Range. Snows can turn to rain as early as February or continue well into May. This means keeping an eye on the weather patterns is especially important when you’re looking to keep your trees healthy. Pay attention to the weather forecast and watch for upcoming storms or dry spells and plan your watering routine accordingly. During frequent storms or extremely cold conditions, consider turning off your irrigation system. Remember, melting snow will do a great job of keeping the roots hydrated and leaving the system on can do long-term damage to the system’s plumbing. Should Denver go without moisture for a few weeks, bust out that watering can or turn the sprinklers back on a few times each week.

Make Use of Mulch

Mulch does more than make a garden look nice—it protects the roots and soil from damage due to erosion or improper drainage. Even if your trees are well established, using mulch around the roots can only help them grow. Over time, the wood used in the mulch breaks down, depositing nutrients in the soil without the use of chemical-based fertilizers. This helps rejuvenate the soil around established trees, making it easy for them to continue to grow well throughout the year. The more available nutrients trees have access to, the stronger their roots will become and the more resistant they’ll be to common hazards like pests, diseases, and drought.

Incorporate Fertilizer Into Your Watering Efforts

Though water helps trees grow and thrive and mulch helps improve the condition of the soil, it may not always be enough. In some cases, mixing a small amount of fertilizer with water is a great way to kill two birds with one stone. Not only are you providing the tree with the hydration it needs, but you’re also giving your tree additional nutrients. In appropriate amounts, fertilizer can strengthen the tree. Keep in mind that fertilizing is not a substitute to regular watering. In fact, it should only be done occasionally and is best handled by a professional landscaper who can assess the overall condition of the tree.

Trees Need Their Own Irrigation System

While your sprinklers may be enough to keep your lawn hydrated even during drought-like conditions, they may not be enough for your trees. Traditional sprinkler systems can lose up to 50 percent of the water they put out to evaporation. While this is effective for grass and other plants with shallow roots, it’s not ideal for trees and large bushes with deep roots. Relying on sprinklers alone will not only increase your water bill, but it will also keep your trees from getting the water they need to grow properly. Over time, this can result in stunted growth, disease, or even death of the plant. Instead, you’ll want to supplement your sprinkler system by either hand-watering the trees or installing an underground drip irrigation system which can maintain moisture in the soil without losing water to evaporation. Best of all, drip irrigation systems are low maintenance and reduce your landscaping’s water consumption by depositing water exactly where it’s needed.

Get Rid of Dead Growth

Regular tree trimming is good for your landscaping, but it can also bolster your watering efforts. Well-hydrated roots transfer nutrients from the soil to the rest of the tree. When the canopy is filled with dead or damaged limbs, the nutrients get spread thin throughout the tree, depositing in the damaged areas and depriving healthy parts of the tree. By scheduling a tree trimming appointment in early spring, your tree will be able to send those nutrients where they need to go more easily.

Don’t Be Afraid of Making a Hard Choice

Droughts are never entirely predictable and what may start out as a minor drought can quickly turn to a major dry spell that results in water restrictions across the county. If the situation gets bad enough that you’re forced to choose between your grass and your trees, always choose your trees. Remember, sod can be replaced easily, but an established tree takes time to grow and develop. It’s far better to preserve your property’s shade trees and reserve your irrigation water for them than it is to maintain a lush green lawn.

Watering your trees should always be a priority, but it doesn’t have to be confusing. At Arbor Garden, our experienced tree trimming and maintenance team wants to help you keep your trees healthy and happy, no matter the season. We’ll assess the health of your trees before starting any work and can make recommendations on proper plant care throughout the year to help you keep your property looking its best. Don’t wait until the growing season begins in earnest. Contact us today to schedule a maintenance appointment before the weather warms up.

Denver Tree Service Calendar For Pests and Diseases

April 4, 2018

Pests and diseases can damage or kill the beautiful trees in our environment. As a homeowner, one of your responsibilities is making sure common pests and diseases do not affect the trees in your yard. But, it can be difficult to keep an eye out for pests and diseases if you don’t know what time of year they are most likely to attack your trees. Make it easier by referencing this Denver tree service calendar for common pests and diseases:


Pests and diseases are typically not active during January and February, so March is the first month that many of them appear. The ash borer is one type of pest that makes its first appearance in the month of March. The ash borer’s larvae begin burrowing into the trunks of ash trees, slowly causing internal damage that can eventually lead to the tree’s death.  

The Dutch elm disease also is present in the month of March. This fungal disease can cause the leaves on elm trees to turn yellow and then brown before prematurely falling off. The fungus quickly spreads down the trunk of tree, causing many of the infected trees to die within one season. Learn more about Dutch elm disease.


The ash sawfly, which feeds on ash tree leaves, tends to appear starting in April. Feeding on the leaves of a tree may not sound harmful, but these pests can actually quickly devour all of the leaves on an ash tree, leaving it completely bare.

The crown borer is another pest that homeowners should watch for in April, but this pest usually only attacks fruit trees. Many people may not recognize the crown borer when they see it because it looks so similar to a bee or wasp at first glance.

The Zimmerman pine moth is yet another pest that often shows up in April. The larvae feed on the inner bark of pine trees, severely weakening the tree. Because the larvae typically target the areas around the branches, a Zimmerman pine moth infestation could cause the branches to die and separate from the rest of the tree. It’s important to take care of this pest infestation right away to prevent branches from falling unexpectedly and possibly injuring someone who is in the wrong place at the wrong time.

During the month of April, homeowners should also start to look for powdery mildew on their trees and grass. Powdery mildew is a fungus that causes grass to turn slightly gray and leaves to look as if they have been sprinkled with a light colored powder. Fortunately, treating powdery mildew is not as difficult as treating other diseases.


The bronze birch borer is one pest that typically starts to cause problems during the month of May. The bronze birch borer larvae dig into the trunks of the trees, where they feed on the inner bark. If left untreated, this pest can eventually kill the tree by cutting off its ability to transport nutrients.

The elm leaf miner is also known for making an appearance in May. Despite its name, this pest can affect many trees and plants besides the elm, including boxwood, hawthorn, and roses. Elm leaf miner larvae hatch within new leaves, leaving a small brown spot behind. If you notice these spots start to appear on tree leaves in your yard, call a tree service company right away.


The cottonwood borer may start to affect cottonwood, poplar, and aspen trees in your yard during the month of June. This pest drills deep into the bark, where it can prevent the flow of nutrients and slowly kill the tree. But, this pest usually only targets trees that have already been weakened by other pests or diseases.

The fireblight is a disease that is present in June, although it usually makes its first appearance much earlier in the year. This bacterial disease affects mountain ash, hawthorn, apple, pear, and peach trees and needs to be treated as quickly as possible. Compared to other diseases, the fireblight is rather aggressive, so it will spread through the tree quickly and cause a great deal of destruction.


Adult Japanese beetles are usually spotted for the first time during July, however the grub can appear months earlier. The Japanese beetle is one of the newest pests to come to the Denver area, and so far, it seems to target any type of plant or tree.

Another pest that is new to the area is the red-headed ash borer, which targets all types of ash trees. Similar to the cottonwood borer, the red-headed ash borer drills holes into the bark of ash trees, eventually causing enough damage to kill the tree. Unlike the cottonwood borer, the red-headed ash tree does not only target trees that have been weakened.


If you have walnut trees, one disease that you should look for in the month of August is the 1000 canker disease. This vicious disease is transmitted by the walnut twig beetle, which is a small brown beetle that has a pill-like shape. The beetle burrows into the bark, where it introduces this fungal disease to the tree. Exposure to the fungal disease will kill the surrounding tree bark tissue, leaving what is known as a canker. Walnut twig beetles can create a lot of these cankers in a short period of time, which is why this disease is known as the 1000 canker disease.

The cankers may not be immediately obvious due to their size and location. Many homeowners notice the yellowing of the leaves on the tree prior to recognizing the signs of cankers on the bark.

Common Tree Care Mistakes to be Aware of in Denver

March 21, 2018

The ideal environment for trees to grow in is one that is free from obstacles and is one where they are able to thrive without much intervention. Trees thrive in natural environments where they can grow in their natural habitat. Trees that grow in an urban and suburban environment are not as well adapted to the elements that come with city living. Growing conditions in a city environment are not as ideal for a plant, and it can require additional care and attention. As a result, it is important to be aware of the common mistakes people make when trimming their trees in Denver.

Planting too deep

Regardless of if your tree was planted last year or a decade ago, if it was planted too deeply, it may still be suffering from the effects of being too far in the ground. Tree roots do much better in shallow soil, as it allows for ample oxygen, water, and warmth. By planting your tree too deeply, it will be deprived of these elements and its growth will suffer as a result.

For planting purposes, your tree’s root flare, which is the part where the roots begin to widen, should be planted at ground level or slightly above ground to allow for optimum growth conditions. If the roots of your tree have been planted below the surface of the ground, it is recommended to excavate the area to allow for more root exposure.

Roots may also begin to grow back towards the trunk, which creates a ‘girding root’. This root can encircle the plant, causing a restriction in the movement of water and other nutrients. If you come upon a girding root, it should be carefully removed for the benefit of the tree.

Damage from equipment

In the process of caring for a lawn, heavy equipment can sometimes interfere and damage your trees. If a tree has been scrape hard enough, it can permanently damage the bark and cambium area. If the cambium layer has been damaged, it can restrict the flow of water and nutrients from the roots to the branches, which can negatively affect the overall health of the plant.

A wounded area from mechanical damage can also be an entry point for pests and diseases, and this leaves the plant vulnerable to decline. By employing a protective area of mulch around your tree, it can not only be a benefit to the soil but it can also be a constant reminder to landscapers and anyone else who make work on your yard that your tree to keep equipment away. Young trees are particularly vulnerable to damage from equipment, which can heighten the need to have some sort of barrier around them.

Over or under irrigation

Trees need the proper amount of moisture to thrive, and supplying your tree with too much or too little water can lead to poor health. The ultimate result from having improper water inputs is that your tree will not go through enough photosynthesis to stay in optimal conditions. Many gardens and properties employ automated watering systems, which can be a great way to maintain consistent watering schedules. However, this is not always perfect, as weather and plant conditions may necessitate an increase or decrease in the amount of water the plant receives.

The amount of water required depends on the specific species requirements, as well as changes in weather conditions. In this way, it is important to consider the placement of species, as you don’t want to place a tree that requires a lot of water next to a shrub that requires very little water. When placing your irrigation system, give special attention to where the water hits the tree, as you don’t want the water to be consistently hitting the trunk and leaves, as this can lead to decline of the plant.

Too Much Mulch

Having too much mulch around your tree can be a negative factor for your tree. Although the practice of volcano mulching can look aesthetically pleasing, it is harmful for the health of the tree. Volcano mulching keeps the bark moist, which can lead to fungi and pests attacking the plant.

Wood chips can be a great choice to utilize as a form of mulch. A layer of 3-4 inch high mulch can be all that is needed in order to conserve moisture and maintain the temperature of the soil.

Poor Pruning Practices

Another way in which your tree can be harmed is due to poor pruning practices. This can be when you prune too much, or make improper cuts that is ultimately detrimental to the health of the plant. Pruning not only changes the shape of the plant, it also affects how the plant will continue to grow and thrive.

Removing too much from a tree can result in poor growth and can lead to the tree being permanently damaged. Improperly trimming your tree can result in dead wood and branches that are not growing to their full potential.

It is important to employ qualified arborists who take time to prune your plant to the best shape and form, not only for the look of the plant but for the overall health of the plant. During the course of any pruning project, the general rule is that you don’t want to remove more than 25% of the crown, as this can be harmful to the tree. Your arborist should take care not to remove too many live branches, and should focus on removing the ones that are dead or are in poor decline as much as possible.

Incorrect pruning cuts can lead to your tree having a canopy that is too dense or too barren, and can make your tree look unsightly. This makes the importance of selecting an arborist who is experience and knowledgeable all the more important, as the health of your tree is something you shouldn’t take lightly.

Your Denver Tree Service Shares a Few Simple Ways to Prepare Your Trees for Spring

March 7, 2018

Springtime in Colorado is beautiful. The plants start blooming, the temperatures rise, and the promise of summer is always on the air. However, with those changing conditions come spring storms that can wreak havoc on your landscaping, trees, and even your home. The last thing any homeowner should have to deal with is damaged landscaping at the height of the growing season. Your trusted Denver landscaping companies want to help. Here are a few simple tips to get your yard ready for all that springtime weather can throw at it.

Inspect Your Trees

The first thing every homeowner should do is visually inspect their trees before spring is in full swing. Look for cracks in the trunk that could house pests or turn into weak spots during a windstorm. Inspect the canopy for damaged branches and limbs that might become a hazard during one of the Front Range’s notable windstorms. If you see anything that looks like a possible hazard, schedule an appointment with a tree trimming service. They’ll be able to assess the extent of the damage and develop a proper solution to protect your home.

Clear Away Debris

Winter weather can take its toll on tree health. When the temperatures start to rise, take the time to pick up any debris and limbs that may have fallen during the colder months. This will help prevent pests and insects from taking up residence in your trees, keeping them healthier for the spring growing season. Remember, insects like termites and beetles can do long-term damage to even the healthiest trees. When left unchecked, infested trees can become a major safety hazard, often weakening to the point of collapse in gusty conditions. Though removing fallen limbs is not the only thing you’ll need to do to protect your trees from common insects and diseases, it will still help significantly.

Add Supports

For younger trees, especially ones you planted in the last year or two, you’ll want to make sure they have the support they need to continue growing. Remember, it takes time for root systems to anchor themselves in the soil. If the tree is too young, it may lose its footing after a heavy rainstorm or windstorm. Rather than leaving it up to chance, install supports around the trunk of the tree. This will give the tree something to brace against during high winds and keep the trunk upright without doing damage to either the bark or the root system.

Schedule an Inspection with an Arborist

Some signs of damage are difficult to spot unless you’ve seen the problem before. For many homeowners, this means they’re leaving potentially dangerous trees on their property without taking the proper precautions to keep their house and surrounding property safe. Scheduling an appointment with an experienced arborist will give you the peace of mind knowing that your trees are safe enough to leave for the growing season. Should anything be damaged or have underlying issues, an arborist will be able to develop a plan of treatment or discuss removal options. Arborists pride themselves on doing what’s best for the trees and they’ll work to make sure your yard looks its best without putting your home at risk for damage.

Make Sure Your Home is Ready

While trees more often do damage to nearby structures, flying debris from the house can do damage to the trees. Inspect your roof for damaged shingles and loose roof flashing. When these items get carried off by high winds, they can cut into the bark of nearby trees or, worse, do damage to parked vehicles and other parts of your home. If you notice any issues, have them repaired as soon as possible. This is both beneficial to your home and your landscaping and can save you money down the road.

Knock Snow Off Low-Hanging Limbs

Let’s face it—springtime often brings heavy snows, even with temperatures starting to warm up. Anyone who has lived in the Denver area for more than a few years knows that May snows can be incredibly wet and heavy. If you wake up to several inches of the white stuff, check your trees. Gently knock the snow off of low-lying branches to alleviate some of the stress on the limbs. This will help reduce the risk of cracked and broken branches that can destroy the way your landscaping looks once the growing season is in full swing.

Care for Other Plants

Though trees are a large part of your landscaping, the garden beds, shrubs, and smaller features still need attention, especially as we transition from winter into spring. Mulch the soil with a high-quality wood mulch to protect the nutrient-rich dirt from erosion and wind. The same method can be applied around the roots of younger trees to help insulate their root systems during the final frost of the year. Should temperatures drop below freezing, cover young plants, flowerbeds, and shrubs with lightweight blankets to keep the frost off the plants.

Schedule Preventative Trimming

Get a jumpstart on tree maintenance and keep your yard and house safe by scheduling preventative trimming with your tree service. By letting an expert take care of overgrowth and potentially damaged or dying limbs before the growing season, you’ll set your trees up for a more successful spring, improve the appearance of your shade trees, and prevent damage during the last few frosts. Best of all, tree trimming at the appropriate time helps trigger growth, encouraging the trees to produce leaves quickly and consistently through spring and into summer.

Follow these tips and help get your yard ready for the rising temperatures without compromising the health and wellbeing of your trees.

Reason to Have Your Stump Removed in Denver

February 21, 2018

When you have a tree removed, you are left with a stump, and unless you seek professional stump removal services, it will remain there for a very long time. There are a variety of reasons to consider having your stump removed in Denver, and many of them aren’t as apparently obvious as others in the grand scheme of things.


Let’s be honest: stumps are not very pretty. They are the last vestige of your wooded companion that is no more. They are the remnants of a once thriving organism that may have been with you and your family for generations. But beyond any nostalgia for the tree that once was, they also happen to be ugly and unsightly. The beauty potential of your yard is greatly reduced when you have a leftover stump.

Many people decide to leave the stump of their tree in place, as they don’t want to spend the extra money necessary to remove it. As a result, they are left with a slowly decaying piece of wood that restricts any landscaping projects in the future, and is generally a major eyesore, especially if the tree was in your front yard. Removing the stump from your property can allow you to beautify your landscape, and opens up more possibilities for gardening projects or future tree plantings.

Stumps Can Create New Tree Growth

If you decide to leave the remnants of your old tree behind by not removing the stump, you may open yourself up to having a new tree sprout up in its place. Stumps that are not removed can allow new tree sprouts to grow up in their place. These sprouts can grow up around the stump, which can look unsightly and can eventually create the need for these to also be removed.

New sprouts often times continue to come back, which can necessitate the use of chemical sprays to ensure that the sprouts do not continue to come back. This can be an added cost that is undesirable for any homeowner to have to undertake. These new trees can leach nutrients from nearby plants, ultimately doing harm to your surrounding landscape. This is a step that you do not want to have to take, and can be avoided with the removal of the stump.

Stumps are Hazardous and a Pain to Maneuver Around

Stumps are not only a pain in your side when it comes to their affect on your landscape, they can also create a hazard for you if you have small children or if anyone is not carely when navigating around them. By leaving your stump instead of removing it, children that are playing in your yard will have to avoid tripping over it. Additionally, if a neighbor trips over your stump and is injured, this can create a liability for you as a homeowner.

Stumps are also a pain to maneuver around in the course of maintaining your yard. Regardless of if you or your landscaper is the one responsible for cutting the grass and maintaining the property, having a stump in the ground will create an inconvenient obstacle to steer around. If you are weeding or mowing, you will constantly have to steer clear of your stump, which can make the chore of cutting the grass a bigger headache than it needs to be. By removing a stump out of the picture, you will not only reduce your headache, but you will save time by not having to constantly avoid the stump.

Stumps Take up Yard Space that can be Reserved for Other Projects

The presence of a stump can be a burden and a nuisance to a homeowner, specifically regarding the potential of future landscaping projects. By having a stump that is not removed, you are restricting your ability to take on new landscaping projects. If you are someone who sees their yard as a canvas to paint your personalized touch onto, having a stump in the ground will greatly reduce your ability to take on any project.

If you are gardening or want to improve your land through other landscaping projects, you will constantly have to factor in the placement of your stump when taking on any design. Having a stump in the middle of a flower or vegetable garden can not only look silly, but it can also be detrimental to the health of any plant you intend to grow nearby.

By removing your stump, you will free up precious yard space to take on that new project for your Denver home. It can open up your landscape in ways you didn’t think were possible prior to removing the stump, which can allow for your own landscaping renaissance. It may cost you a bit more in the short term to have a stump removed and ground down, but by doing so you give yourself greater wiggle room to unleash your creative mind onto your yard.

Stumps Attract Insects

By leaving a stump in your yard, you open yourself up to attracting insects and pests. Certain critters will see your rotting and decaying stump as their next meal. Termites, beetles, ants, and other wood-boring insects will dive right into your decaying stump. By attracting these pests, you may end up dealing with their presence inside of your home as well. This can lead to costly repairs and expenses far beyond the cost of removing the stump itself.

It can take many years before a stump is fully decayed and can be removed with a shovel and simple household tools. This means that for years to come, your yard may be a target of pests and other undesirable organisms. On this fact alone, it may be advisable to consider having your stump removed from your yard before it becomes a bigger problem.
