If you’ve noticed blackened branches or scorched-looking leaves on your trees this spring, fire blight might be to blame. This aggressive bacterial disease (not actually a fungus!) affects many common trees in Colorado, especially apple and pear species. And if left untreated, it can spread rapidly and kill large sections of a tree.

Here’s what Colorado homeowners and land managers should know about fire blight, how to spot it, and what to do next.


Is Fire Blight a Fungus?

No, fire blight is not a fungus — it’s a bacterial disease caused by the pathogen Erwinia amylovora.

This is a common misconception because it spreads and damages trees in ways that can look similar to fungal infections. But unlike fungi, which produce spores, fire blight bacteria multiply and spread through tree tissue, wounds, and blossoms, especially during wet spring weather followed by warmth.

What Is Fire Blight?

Despite its name, fire blight is caused by a bacterium called Erwinia amylovora, not a fungus. It infects trees through blossoms, wounds, and natural openings, especially during cool, wet springs followed by warm weather — which we often see across Colorado’s Front Range.

Once inside the plant, the bacteria multiply quickly and spread through the tree’s vascular system, damaging tissues and causing the “burnt” appearance that gives fire blight its name.


Trees Most at Risk in Colorado

Fire blight primarily affects members of the Rosaceae family, including:

These trees are popular throughout the state for their spring blossoms and hardiness, which unfortunately also makes them frequent fire blight victims.


How to Identify Fire Blight

Look for these telltale signs:

Often, fire blight spreads so quickly that a tree can go from healthy to heavily damaged in a single growing season.


Why It’s a Big Deal in Colorado

Colorado’s changing spring temperatures and periods of moisture can create ideal conditions for fire blight to thrive. Once the bacteria are present, pruning alone may not be enough — and improper cuts can actually spread the infection.

Because many homeowners in areas like Denver, Boulder, and the foothills plant susceptible species, entire neighborhoods can experience outbreaks that move from tree to tree.

What You Can Do: Prevention & Treatment

1. Prune infected branches.
Cut at least 8–12 inches below visible infection. Sterilize pruning tools between cuts with alcohol or bleach solution to avoid spreading bacteria.

2. Avoid excessive nitrogen fertilizer.
Too much nitrogen encourages lush, new growth — which is especially vulnerable to infection.

3. Apply a bactericide.
Copper-based sprays can help, especially if applied during bloom. However, they must be timed correctly and applied by professionals to be effective.

4. Remove severely infected trees.
In some cases, tree removal is the best way to prevent fire blight from spreading to nearby trees.

5. Call a certified arborist.
Professional tree care companies in Colorado are equipped to diagnose, treat, and manage fire blight outbreaks safely and effectively.

Defensible Space Inspection Colorado

Protect your property and Colorado’s forests with professional fire mitigation services. Splintered Forest specializes in reducing wildfire risk through strategic tree removal, defensible space creation, and expert assessment to keep your home and community safer.

Wildfires are an ever-present threat in Colorado, especially for those living in the wildland-urban interface (WUI). Creating and maintaining defensible space around your property is a critical step in safeguarding your home and community. Here’s what you need to know to get started.

As wildfires have become more frequent and more destructive in recent years in Colorado. Whether you’re located in the foothills, nestled in the forest, or near the wildland-urban interface, fire mitigation is no longer optional—it’s essential. At Splintered Forest, we help Colorado homeowners reduce their wildfire risk through professional defensible space inspections, strategic fire mitigation, and forestry services.

What Is Defensible Space?

Defensible space refers to the buffer zone you create between a building and the grass, trees, shrubs, or wildland area that surrounds it. This space is designed to slow or stop the spread of wildfire and protect your home from direct flame contact, radiant heat, and ember intrusion.

Creating a defensible space isn’t just about trimming branches. It’s about zoning your property into three strategic areas—each requiring specific treatment.

Fire Mitigation Best Practices

Defensible Space & Fire Mitigation: How Colorado Homeowners Can Stay Wildfire-Ready

Wildfires are an increasing threat across Colorado’s Front Range. As our communities grow closer to wild land areas, the need for proactive fire mitigation has never been more urgent. At Splintered Forest Tree Services, we specialize in helping homeowners, HOAs, and property managers reduce wildfire risks by creating and maintaining defensible space—a proven method for protecting structures from wildfire damage.

What Is Defensible Space? How to Protect Your House from Wildfires.

Defensible space is the area between a building and the surrounding vegetation that’s strategically managed to reduce fire danger. Creating this buffer slows the spread of wildfire, reduces fuel, and provides firefighters with a safe zone to defend your home.

The Colorado State Forest Service and Wildfire Partners recommend a zoned approach, dividing your property into three defensible zones based on their proximity to your home.

🔥 Zone 1: Immediate Zone (0–5 feet from your home)

🔥 Zone 2: Intermediate Zone (5–30 feet)

🔥 Zone 3: Extended Zone (30–100 feet and beyond)

Why Fire Mitigation Matters in Colorado

Colorado’s arid climate, wind-prone weather, and dry vegetation make it highly susceptible to fast-moving wildfires. Many homes lost to wildfire are ignited by embers, not direct flames—meaning preparation around your home’s perimeter is crucial.

Defensible space isn’t just a suggestion—it’s often required. Many counties in Colorado now require fire mitigation inspections for new construction, property sales, or insurance compliance. Splintered Forest offers county-approved defensible space assessments that meet local regulations and help you stay compliant.

Plant Health Care and the Emerald Ash Borer Life Cycle in Colorado Ash Trees

From Egg to Invading:  The Full Emerald Ash Borer Life Cycle

The Emerald Ash Borer or more commonly referred to as EAB goes through many cycles before emerging as a mature adult.  Continue reading to learn more about each part of the invasive pests life cycle. 

Life Cycle of the Emerald Ash Borer

The life cycle of the emerald ash borer repeats annually:

Understanding this cycle is key to preventing infestations and maintaining the health of ash trees. The emerald ash borer life cycle is synchronized with seasonal changes, meaning effective management must be timed correctly.

EAB Ash Borer life cycle

EAB Eggs

Eggs are approximately 1mm in size and laid by females in the cracks and crevices of the bark of ash trees. Females can lay anywhere from 40 to 200 eggs that will hatch about two weeks later. Upon hatching the larvae will then burrow into the trees inner bark layers and begin to feed.

The emerald ash borer egg is a critical but often overlooked stage in the EAB life cycle. These eggs:

Since EAB eggs hatch quickly, preventive treatments should be applied in early spring before larvae emerge.

Emerald Ash Borer Eggs

EAB Larvae

The larval stage is the most dangerous stage of the beetles life. Larvae tunnel into the bark upon hatching from their eggs. They then spend all of their time eating tissues that the tree would need to transport water and nutrients. This damage of vital tissues can quickly become deadly to the ash tree because of the number of larvae doing damage and their aggressive nature.  As they feed their movements form a distinct S-shaped pattern which can be seen when bark is removed. This is the stage most often selected to chemically treat an infestation as the larvae will feed on treated wood and then die. 

Emerald Ash Borer Larva

Emerald Ash Borer Larva

The emerald ash borer larva is the most damaging stage of the EAB life cycle.

Once larvae are present, systemic insecticides or tree removal may be the only options.

Overwinter

After feeding on tree matter for one to two years, the larvae will overwinter and begin to pupate in the spring. This overwintering in the tree keeps the larvae and pupae safe from cold weather and potential predators. 

Pupae

The pupa is the final form before emerging as a mature adult. It merely is a stage to facilitate metamorphosis to the final adult beetle stage. 

Adults

Adults can emerge any time between late-May and September, but the majority of them will emerge by July and begin to mate and lay eggs. As they exit, they form D-shaped exit holes which can be used to identify the beetle’s presence in a tree. The adult form does minimal damage to the tree as they usually feed on the leaves of the tree and mate before dying, but their ability to fly up to a quarter mile aids in their spread.

 

Understanding Emerald Ash Borer Damage: Signs, Treatment, and Prevention

The Emerald Ash Borer (EAB) poses a significant threat to ash trees, causing extensive damage throughout its life cycle. Recognizing the signs, exploring treatment options, and understanding preventive measures are crucial for preserving these valuable trees.

Signs of Emerald Ash Borer Damage

Identifying signs of EAB damage is vital for early intervention. Look for distinct D-shaped exit holes left by emerging adults, as well as canopy thinning, bark splits, and epicormic shoots—new growth arising from the tree’s base or trunk. Recognizing these indicators early can be instrumental in minimizing the impact on ash trees.

Treatment for Emerald Ash Borer

Timely treatment is essential to combat EAB infestations. Various methods, including chemical treatments and insecticides, are available. Chemical treatments during the larval stage can effectively control the population by targeting feeding larvae. Consulting with arborists or plant health care professionals is recommended to determine the most suitable treatment approach for specific situations.

Preventive Measures and Tree Treatment

Implementing preventive measures is crucial in areas prone to EAB infestations. Regular inspections, early detection, and prompt treatment can help protect ash trees. Consider systemic insecticides that are absorbed by the tree, providing long-term protection against EAB. Establishing a proactive treatment plan can significantly enhance the resilience of ash trees.

Mapping EAB Presence and Spread

Stay informed about the geographical distribution of EAB through maps tracking its presence. Understanding the areas affected can guide proactive measures and help prevent the spread of this invasive species.

Origins and Spread of Emerald Ash Borer

Knowing where the EAB originated is essential for understanding its introduction to new regions. The beetle is native to Asia and likely arrived in the United States through international trade. Tracking its spread provides valuable insights for managing and mitigating its impact.

Colorado’s Battle Against Emerald Ash Borer

Colorado, including the Denver Metro area, has witnessed the invasion of EAB. Being aware of local infestations, understanding treatment costs, and collaborating with professionals is crucial for effective management.

Before and After: Assessing Emerald Ash Borer Damage

Examining the transformation of ash trees before and after EAB damage showcases the severity of infestations. Utilizing visual aids, such as damage maps, illustrates the impact and emphasizes the importance of proactive measures.

What Do EAB Beetles Look like?

Distinguishing between EAB and similar-looking beetles is essential for accurate identification and treatment. Identify EAB look-a-likes:

See the University of Nebraska EAB Look-a-likes chart. EAB adults are smaller than a penny approximately 8-13 mm long. They are about the size of a cooked grain of rice: between 3/8- and 1/2-inch long and 1/16-inch wide. Due to their size, they can often go undetected, but they can be seen on ash bark and leaves during warmer months, at this time they might attract woodpecker activity.

Before and After Emerald Ash Borer Damage

Do you live in the Denver Metro area? Do you have an ash tree on your property? The EAB has been detected most recently in the Littleton area and continues to spread.

Benefits of Using Wood Chips in Your Garden – Wood Chip Mulch (Bulk Delivery) Landscaping 

There are several advantages to incorporating wood chips into your garden:

  1. Mulching: One of the primary benefits of using wood chips in your garden is their ability to act as a natural mulch. When spread over the soil surface, wood chips create a protective layer that helps retain moisture, regulate soil temperature, and suppress weed growth. This mulching effect is particularly beneficial in areas with hot summers or cold winters, as it helps to insulate the soil and protect plant roots.
  2. Soil Improvement: As wood chips break down over time, they release nutrients into the soil. This gradual decomposition process enriches the soil, improving its overall quality. The organic matter provided by wood chips enhances soil structure, promotes better drainage, and increases the soil’s ability to retain moisture. Additionally, the nutrients released by the wood chips nourish plants, supporting their growth and vitality.
  3. Erosion Control: Wood chips play a crucial role in preventing soil erosion. By reducing water runoff and maintaining soil structure, they help to stabilize the soil and prevent it from being washed away during heavy rain or wind. This erosion control is especially important on slopes or areas prone to erosion, as it helps to maintain the integrity of the landscape and protect against soil loss.

Fruit trees can be a valuable part of any landscape. Whether it’s for their fruit or just their flowers it is important to care for your trees to make sure they are around for years to come.

 

PRUNING FRUIT TREES IN COLORADO

Planting fruit trees in Colorado can be incredibly rewarding, but the unique climate and growing conditions require careful planning and maintenance. With the right tree selection, proper pruning techniques, pest management strategies, and ongoing care, you can enjoy fresh fruit from your own backyard for years to come.

Pruning your fruit trees is a key part of caring for your fruit tree.

Mature trees: Maintaining good airflow and structure in older trees is the most important thing. Over pruning can be harmful to your tree so keeping cuts to a minimum and avoiding unnecessary cuts is the goal.

 

Young trees: Young trees are easier to work with in terms of pruning because of their faster growth patterns and lack of older mature branches. Young trees can also be pruned to fit specialty structure methods like espalier.

 

DISEASE AND PEST MANAGEMENT

Fruit trees can be difficult to care for in terms of diseases and pests as some varieties are prone to common diseases like fireblight and cytospora canker. These diseases can add extra cost to the care of your trees, but are avoidable if you care for your tree properly. Preventative sprays can help to mitigate repeat infections from fireblight in the chance that your tree becomes infected, but the best method for protection is timed pruning in the dormant season.

 

Important things to remember:

Pruning Fruit Trees in Colorado

Pruning is one of the most important steps in maintaining the health and productivity of your fruit trees. It helps shape the tree, encourage better fruit production, and prevent disease by improving airflow and sunlight penetration. However, improper pruning can do more harm than good, so it’s important to follow best practices based on the tree’s age and growth stage.

Mature Trees: Prioritizing Airflow & Structure

Older fruit trees require pruning to maintain structure, reduce overcrowding, and ensure that branches get adequate airflow and sunlight. Without proper pruning, excessive growth can lead to weaker limbs, reduced fruit production, and increased susceptibility to disease.

Young Trees: Shaping for Long-Term Growth

Pruning young trees is essential for developing strong branch structure and establishing a solid foundation for future growth. Young fruit trees tend to recover quickly from pruning and can be shaped using specialty techniques.

Pruning should always be done during the dormant season (late winter to early spring) before new growth begins. Summer pruning is only recommended for removing minor deadwood or shaping the tree slightly.

Disease & Pest Management

Colorado’s climate can present challenges for fruit tree growers, particularly when it comes to common pests and diseases. Many fruit tree varieties are susceptible to bacterial and fungal infections, as well as insect infestations, so proactive care is essential.

Common Fruit Tree Diseases to Watch For:

Pest Control Strategies for Fruit Trees

Regular monitoring, proper pruning, and well-timed applications of organic or chemical treatments can keep fruit trees healthy and productive.

Ash trees are a popular native tree species in the United States and are often planted as street or landscape trees. Ash trees are part of the Fraxinus genus and there are various species of ash trees in Colorado, including green ash and white ash. It is common to confuse an Ash tree with various other trees that look similar, such as black walnut, maple, boxelder, hickory, or dogwood trees. To correctly identify ash trees, you will need to closely examine various parts of the tree.

Ash Tree Branches

To start identifying an ash tree, you can look at its branches. You can either pick up a dead stick that has fallen to the ground or pull down a branch so you can get a close look at it. Check to see if the branches have opposite branching. This means that when branches grow from the main branch, they all start at the same position. Other trees feature alternate branching, with branches growing from the main branch alternating left and right. For example, maple, dogwood, and boxelder trees have opposite branching, while oak, cottonwood, and hickory trees have alternating branches. You can also look for fresh branch buds. On ash trees, the buds will be directly across from or opposite each other. Here are more Useful Tree Resources to explore.

Ash tree leaves

Ash Tree Leaves

Another way to confirm that you have an ash tree is to look at its leaves. The leaf structure of an ash tree is compound rather than single.  From this point you can count the number of leaves. You will either see a single leaf or 5 to 7 (some varieties have up to 11) smaller leaflets that branch out from it. A single leaf tree, such as a maple tree, has one big leaf that extends from the branch. Both ash trees and boxelder trees have compound leaves, so be careful with getting them confused. Another characteristic of ash tree leaves is that they have either smooth or finely toothed edges.

Ash Tree BarkIdentify ash tree bark - https://splinteredforesttreeservices.com/useful-tree-service-resources/

If you are looking at a mature ash tree, the bark can help with identification, too. Ash trees will have a diamond-shaped bark pattern on both white ash and green ash trees. This helps differentiate them from maple trees. Young ash trees may not have this distinctive bark pattern, but you should be able to rely on other characteristics if this is the case.

Ash Tree Seeds

Ash tree pods

An ash tree will have either light green or brown clusters of seeds (known as a Samara). The seeds on an ash tree are paddle-shaped and resemble small leaves and dangle from the tree in big clusters. Don’t assume that a tree that lacks seeds isn’t an ash tree. Some ash trees are seedless. Only in late autumn and early winter can seed clusters develop. Boxelder/maple seeds are similarly clustered, although they resemble wings rather than paddles.

Why Is Identifying Ash Trees Important?

Knowing whether or not you have an ash tree on your property is important, especially in the state of Colorado. The Emerald Ash Borer (EAB) made its way to Colorado in 2013, and this pest has become a serious threat to ash trees. If you have an ash tree that has been infested with the Emerald Ash Borer, you will want to contact a professional to treat infected trees as soon as possible. EAB can be prevented, so if you live within 15 miles of a known EAB infestation, you may want to consider treating your ash trees.

How to Identify Different Types of Ash Trees

Ash trees are diverse, with several common ash species spread across various regions. By understanding the distinguishing characteristics of these trees, including their leaf shape, bark texture, and seasonal changes, you can confidently identify different types of ash trees.

Key Ash Tree Species

  1. Green Ash (Fraxinus pennsylvanica)
    The green ash, scientifically known as Fraxinus pennsylvanica, is a bright green species found widely across North America. This species is resilient, often thriving in wet soils near rivers and lowlands. Its leaves turn a vibrant yellow in fall, making it easy to spot during autumn.
  2. White Ash (Fraxinus americana)
    The white ash, or Fraxinus americana, is another prevalent ash species. Known for its sturdy wood and straight trunk, this species is highly valued in landscaping and for creating strong, durable wood products. Its leaves also turn a beautiful shade of purple in fall, contrasting with the bright green appearance it holds in summer.
  3. Black Ash
    Black ash trees, while less common than green and white ash, are native to the Northeastern United States and parts of Canada. Unlike other ash species, black ash has a thinner bark, and its wood is often used in basket-making due to its flexibility and durability.
  4. Blue Ash
    Found in the Midwest, blue ash trees are unique for their striking bluish bark when cut, giving the tree its name. This species is more drought-tolerant than other ash trees, making it resilient in drier environments.
  5. European Ash (Fraxinus excelsior)
    Although native to Europe, the European ash (Fraxinus excelsior) can be found in some North American gardens and landscapes. It’s known for its tall, graceful structure and adaptability to different soil types, making it a popular choice among landscapers.

Threats to Ash Trees in Colorado: The Emerald Ash Borer

EAB beetle with wings spread

One of the greatest threats to ash trees globally is the emerald ash borer (Agrilus planipennis). This invasive insect targets ash trees by burrowing under the bark, disrupting nutrient flow, and eventually killing the tree. The emerald ash borer has particularly impacted green ash and white ash populations, leading to extensive conservation efforts.

Recognizing Ash Trees by Color and Shape

Ash trees are often recognizable by their bright green leaves, especially in the spring and summer months. Each ash species has its unique leaf arrangement and fall colors, aiding identification:

By examining these visual clues, tree enthusiasts and landscapers can better identify each ash species and support efforts to protect them from pests like Agrilus planipennis.

Tree Removal of My Ash Tree

Schedule Tree Trimming for you Ash Tree

There are many reasons you may need to have a tree removed. At times, diseased or dying trees will need to be removed to ensure there is no damage to the house itself. Also, there are safety issues involved and otherwise perfect trees must be removed. If you must remove trees around your home, consider repurposing wood! You could use it in a variety of ways from furniture to shelving and keep elements of your once tall trees in your Denver home.

Table and Chairs

Transforming and repurposing old wood into a table is a fantastic way to add a custom style in your home. Depending on the style of your home, you can make or have a table made to fit. For farmhouse or traditional homes, consider a table made completely of wood. Create a long wooden table paired with a gorgeous color stain that helps it fit with other colors in the room. For modern or contemporary homes, consider a wood top with a metal or pipe bottom and legs. This unique style will stand out and provide flair to your home. Pair it with a pair of custom made wooden chairs. In addition to chairs, consider making wooden stools of your repurposed wood, or add a bench on one side of your table.  Have a large backyard? Consider adding a picnic table or chairs made from your old tree’s wood!

Cabinets and Shelving

Can you ever have enough storage space? Repurposing wood as a cabinet or shelf is a great addition to your home! Plus, you will have complete control and can build or have something build perfectly for an area. For instance, choose a corner cabinet to store dishes, essentials, supplies and more. Once it is built, you can add a stain to it, or paint it a color that matches other elements of the room. Next, wood shelving is a very durable option. From thick to thin shelves, you can really have fun and play with some great ideas that look great in any room. You can also put wood shelves on a grid system or using metal or steel pieces to mount them on the wall.

Bedroom Furniture

Use your reclaimed wood to transform your bedroom. Many love the way a wooden structure looks. However, that is not your only option! You can complement your current bedroom arrangement with a wooden headboard. There are so many options to customize a headboard.
