Decision guide for treating or removing ash trees faces emerald ash borer

NEW LONDON, Minn., Sept. 4, 2026 /CourierPR/ -- In a new article for HelloNation, lawn and tree care expert Guy Mayhew of Tree-n-Turf Services provides insights on the decision between treating and removing ash trees, a common concern among homeowners in the Willmar area.

Ash trees have long been valued for their shade and structural beauty, but with increasing concerns about declining health due to the emerald ash borer, many homeowners face difficult decisions. The article identifies several key factors to consider when making this choice, including tree size, overall health, safety, timing, and cost.

According to Mayhew, larger, established ash trees that provide functional or aesthetic value may be worth treating. Smaller trees, on the other hand, may be more economical to replace if they are already under stress. The article emphasizes that tree health is another crucial factor. Trees with full leaf growth, stable canopies, and intact bark are more likely to respond well to treatment. Trees showing signs of thinning leaves, bark splitting, or branch dieback may be too far gone and may require removal.

Safety is also a significant consideration, particularly for ash trees located near homes, sidewalks, or high-traffic areas. A declining tree in a risky location may need to be removed to prevent accidents. Timing is essential, as emerald ash borer treatment is most effective when applied before visible signs of decline become severe. Preventive care can help preserve tree health for years, but waiting too long can limit treatment options and increase the likelihood of removal.

Cost is another factor that influences the decision. Ongoing treatment requires periodic attention and resources. For a healthy tree, this investment can be justified. However, for trees with a poor long-term outlook, the article suggests that removal may be more practical. Comparing the total cost of treatment versus removal helps homeowners make better financial decisions.

The article also highlights the environmental and visual benefits of mature trees, such as supporting local shade, cooling, and neighborhood appeal. These less tangible benefits can influence whether emerald ash borer treatment is worth pursuing. Tree size and location are central to these evaluations.

Ash tree removal, while sometimes necessary, brings its own challenges. Large trees may require heavy equipment, especially in hard-to-access areas. The article advises that planning removal in advance, before the tree becomes unstable, can save time, reduce risk, and prevent property damage.

Regardless of the decision made, the article stresses the importance of ongoing monitoring. Trees receiving treatment should be watched for signs of improvement or further stress. Trees slated for removal should be scheduled early to avoid emergency situations. This proactive approach, especially in the Willmar area, helps homeowners stay ahead of issues related to ash tree health.

Ultimately, the article concludes that deciding between emerald ash borer treatment and ash tree removal is a personal decision shaped by tree size, condition, cost, and safety. There is no one-size-fits-all answer. A careful evaluation of each tree helps ensure responsible and informed outcomes.
