Guardians Under Threat: Understanding the Top 10 Hard Truths About Dutch Elm Disease In Edmonton

In the serene landscapes of Edmonton, a silent threat looms, targeting one of nature's steadfast guardians—the majestic Elms. As urban greenery battles against the unseen adversary, it becomes imperative for locals to grasp the essence of Dutch Elm disease in Edmonton, a menace silently encroaching upon the city's arboreal heritage.

Dutch Elm Disease is a deadly condition that affects all Elm Tree species in Alberta. Caused by a fungus, it clogs the tree’s water conducting system and kills the tree. This disease is spread by 3 different beetle species, which seek out weak adjacent trees to breed. Once matured, the adult beetles fly from tree to tree and spread the fungus.

Read on as we unravel the top 10 hard truths about Dutch Elm disease that demand our attention, prompting reflection on the preservation of these towering sentinels.

1. Silent Invader, Stealthy Destroyer:

Dutch Elm disease, generated by the fungus Ophiostoma novo-ulmi, is a silent marauder, infiltrating the heartwood of Elm trees through the unsuspecting sticky spores and channels of bark beetles and fungal disease. Unseen and often underestimated, this pathogen jeopardizes the very foundation of Edmonton's green canopy.

2. Recognizing Early Symptoms Of Infection:

Watching for early signs and external symptoms of Dutch Elm disease is the first line of defence. From wilted leaves to the characteristic "flagging" of an infected branch, understanding these symptoms can be the key to early intervention and protection.

3. Citywide Impact:

The threat is not confined to isolated pockets; Dutch Elm disease poses a citywide risk due to its rapid spread. Vigilance is paramount, urging communities to unite in a shared effort to safeguard Edmonton's urban forests from this relentless adversary.

4. Eradication vs. Preservation Dilemma:

Balancing the need for eradication with the preservation of Edmonton's Elm trees presents a profound dilemma. The city has to strike a harmonious equilibrium between protecting its natural heritage and preventing the disease's relentless spread. In the early stages, preservation of the infected elm tree is possible, but in the later stages, once the beetle has overtaken, leading to dead branches and more, then eradication is necessary as the risk of infection to healthy elm trees is very high.

5. Civic Responsibility:

The fight against Dutch Elm disease is not the sole responsibility of arborists and city officials; every citizen plays a vital role. From reporting suspicious symptoms to adhering to quarantine measures, Edmontonians collectively bear the mantle of preserving their green legacy through public awareness.

6. Strategies for Resilience:

Understanding the disease's dynamics equips Edmonton with strategic resilience. Through diversified planting, strict pruning regimes, and fostering tree diversity, the city can fortify its green corridors against the persistent threat.

7. Economic Ramifications:

Beyond ecological implications, Dutch Elm disease exerts a tangible economic toll. The removal and replacement of infected trees, coupled with the potential decline in property values, underline the urgency for a proactive stance against this arboreal menace.

8. Educational Imperatives:

Fostering awareness and education becomes paramount in the battle against Dutch Elm disease. A well-informed public serves as a formidable line of defence, nurturing a culture that cherishes and protects the vital green lungs of the city.

9. Innovative Technologies and Research:

Harnessing the power of innovation and research is crucial in outsmarting Dutch Elm disease. From advanced diagnostic tools to exploring resistant Elm varieties, Edmonton must invest in cutting-edge solutions to stay ahead in this ecological chess game.

10. Community Engagement and Collective Action:

The heart of Edmonton beats in the unity of its citizens. Harnessing this collective spirit, fostering community engagement, and instigating a sense of pride in preserving the city's arboreal legacy will be the linchpin in the fight against Dutch Elm disease in Edmonton.

The battle against Dutch Elm disease is not just a struggle for survival between trees and fungus; it is a collective endeavour to safeguard the very essence of Edmonton's identity. As the city stands at the precipice of a green revolution, the time is now to rise, united, against this silent nemesis and secure a vibrant and resilient future for generations to come.

Can You Actually Treat Dutch Elm Tree Disease In Edmonton?

Treating Dutch Elm disease involves a complex decision-making process. While there are some fungicidal treatments available, they are often most effective in the early stages of infection. Once the disease has progressed significantly, especially in mature trees, the chances of successful treatment diminish.

Tree removal becomes a necessary step in cases where the disease has advanced to the extent that treatment is ineffective or the disease has progressed to the point of posing a risk to surrounding elms. Removal is crucial to prevent further spread, as the fungus can be transmitted by bark beetles attracted to infected elms in the area.

Early detection, timely treatment, and professional assessment are essential in determining whether a diseased tree can be saved or if removal is the most prudent course of action. Regular monitoring and swift intervention are key elements in the ongoing battle against this destructive disease. Once the tree has reached the point of needing removal, our experts follow a meticulous approach to the safe removal and preservation of surrounding elm trees. Read on to learn more about our specialized services.

How Do You Ensure A Safe Elm Tree Removal?

Ensuring safe and effective elm tree removal when infected with Dutch Elm disease involves a systematic process by a professional arborist. The way to execute the safe removal of a Dutch elm tree diseased with infectious fungus and elm bark beetles is:

Professional Assessment:

Engage certified arborists or tree removal experts to assess the extent of the infection and evaluate the tree's overall health. Professional expertise ensures a comprehensive understanding of the situation and informs the decision-making process.

Permitting and Regulations:

Check local regulations as well as obtain any required permits for tree removal. Municipalities often have specific guidelines about the removal of infected elms to prevent further spread of disease.

Quarantine Measures:

Implement quarantine measures to prevent the transportation of infected wood, as this can contribute to the spread of the disease. This involves securely bagging and sealing branches and wood before removal.

Safety Precautions:

Prioritize safety during the removal process. Use proper safety gear, including helmets, goggles, and gloves. Ensure the area is cordoned off to protect bystanders and follow industry best practices for safe tree removal.

Proper Equipment:

Utilize appropriate equipment for the removal, including chainsaws, ropes, and rigging equipment. Having the right tools ensures efficiency and safety during the tree removal process.

Tree Felling or Sectional Removal:

Depending on the size and location of the tree, choose between felling the entire tree or removing it in sections. Professional arborists often use a systematic approach to dismantle the tree safely, especially in urban areas where space is limited.


Dispose of the infected wood carefully to prevent the spread of the deadly disease. Since it is full of disease, it cannot be used as firewood in the summer months. Some municipalities have bylaws that prohibit the movement of firewood and have designated areas or procedures for disposing of trees infected with Dutch Elm disease.

Stump Removal:

After the tree is removed, consider whether to remove the stump. Stump removal can prevent potential regrowth of the disease or attract native elm bark beetles, minimizing the risk of further infections.

Soil Sterilization:

Consider soil sterilization in the area where the infected elm wood was removed. This additional step can help eliminate any remaining fungal spores in the soil, reducing the risk of future infections.

Replanting and Future Prevention:

After the removal, consider tree planting with disease-resistant healthy trees. Implement preventive measures, such as regular monitoring of nearby trees, to detect and address potential infections early on.

By following these steps, property owners can ensure the safe and effective removal of an Elm tree affected by Dutch Elm disease, contributing to the overall health as well as resilience of the urban forest. When you aren’t sure how to follow some of these processes, or you just want a professional to take care of it, then reach out to your local licensed arborist, and we will ensure the entire process is handled and followed, as well as ensuring local regulations and permits are followed. Let's protect the arboreal giants to stop the spread of Dutch elm disease.

We had a crew from Trusty Tree Services trim three trees on our property a few weeks ago, sorry for the late review. Couldn't be happier with the whole process. From the estimate to the final clean up, everything went very well. I contacted other companies for estimates, didn't even get a call back. Thanks again Trusty Tree for a great job!

Trusty Tree Services came out and pruned our Amur Cherry tree in Fort Saskatchewan and did a great job. The technicians were knowledgeable and gave me tips on how to better take care of our tree.

We had an amazing experience with Trusty Tree. They gave a prompt estimate for some very difficult trees in our campground. They arrived on time and began work immediately. Their expertise shone through as they brought down the trees on point! Friendly, informative, professional and outstanding workmanship. I would recommend them in a heartbeat. Shout out to Colton, Joe and Adrian - great work!

We had Trusty Tree out this year to shape and thin 4 trees and 3 Mugo Pine shrubs. I was impressed with a quick appt for the quote and then quick response for booking. Our trees were pruned earlier in the season as this was the recommended timeframe, and the Mugo Pine shrubs pruned later in the spring after the new growth appeared. I'm pleased with the crew that came out, they were polite, professional and experienced. We are happy with how our trees and shrubs look and feel the price was fair. We would definitely recommend Trusty Tree and will have them back in the future. Thanks for taking extra time with us to talk about proper pruning too!

I am a new widow and my yard work is so overwhelming, I called Trusty tree to come over and give me a quote. Because my husband who has slways been in love with taking great care of our home,has passed I am here to do it alone.Trusty tree are the most professional people I dealt with..And they actually had the most professional quote,they took pictures of my Tree to elaborate on what needed to be done,and explained why everything had to be done in a certain way...after 3 other companies coming out I realized that Trusty Trees quote was extremely fair. So when the Trusty Tree crew arrived to prune my beloved tree, they were ready, and really understood the sentimental value of my tree that my late husband and I used to sit under every night. The crew members Joe and Shane collaborated beautifully brought down the required amount of my tree..They had a fantastic chipper on site and they also cleaned up the yard so beautifully after the cutting was done...If anyone reads this review,please understand how much that tree meant to me and my late husband. Joe and Shane gave it a loving and caring trim, and they where not only hard working but very informative of the process,and very just great guys,they included their sense of humor to make the trimming process easier on me. THEY were so compasionate and understanding . I thank them for that..... If you are thinking of pruning your gorgeous beloved tree, Trusty Tree has got be your only choice. THESE GUYS ARE THE BEST!!! My name is Christine and if anyone wants to contact me about what a great job this crew did..please do!!!

This was the second time I've used this company for mature tree removal. This time 4 fully grown columnar Aspen trees located close to fencing, a deck and between 2 houses were successfully removed with no damage to the aforementioned structures but also nearby concrete curbing. Work was done as scheduled, quickly and neatly. Very satisfied with the work.

When Trevor came to quote my yard at my new house, he helped me identify all the trees and shrubs, and clearly explained what work needed to be done. When the day came to do the work, Kolton and Carl were friendly and also walked me through what they were doing and why (I'm interested in these things and was asking questions). They did their best to save my cherry that is infected with black knot. Looking forward to having them come back to continue tree maintenance in the future.

We had a tree in our yard that had died a few years earlier and wasn’t sure who to call. We called Sunstar who recommended Trusty Tree to us. Trevor came out to look at our tree. We didn’t realize we had another Tree that was diseased. He sent us a quote very quickly. He was able to book a time for tree removal, stump grinding, as well as planting our new trees. The project was done in the timeline provided. The crews showed up on time or earlier than expected which was amazing! They were very professional. I would hire Trusty Tree again!
