Save Your Minnesota Ash Tree From Emerald Ash Borer
If you live in the Minneapolis & St. Paul metro, there is a good chance you have an ash tree. This common tree species was frequently planted in landscapes and boulevards before 2009. Unfortunately, all unprotected ash trees are at a high risk of dying from the invasive emerald ash borer (EAB). Rainbow can still protect your large, well-placed, healthy ash tree so you can retain the benefits of a mature tree and help preserve our urban canopy.
With over 60,000 ash trees under protection in the Twin Cities, the experts at Rainbow Treecare are committed to saving the urban forest — one tree at a time. Schedule your ash inspection, and take action before it is too late!
What can you expect from our emerald ash borer protection service?
The first step in our emerald ash borer service is an inspection of your ash tree by one of our tree experts. We will evaluate your tree to determine if treatment is still an option. Treatment considerations include:
- Tree size greater than 10” in diameter
- Tree is not competing with other trees, buildings, or infrastructure
- Tree shows no more than 30% of canopy decline if an infestation is suspected
Is Your Ash Worth Protecting?
If your ash tree is healthy, we recommend treating your tree as soon as possible. Please keep in mind, we can only treat ash trees from approximately late May through early September when your tree has green leaves. Our licensed technicians perform EAB treatments by injecting a treatment product into the tree’s trunk above the soil line. The product is then taken up naturally by the tree’s vascular system, the same way nutrients and water are moved throughout a tree. This process allows the product to reach the tree’s living parts, including the leaves, twigs, branches, and trunk.
We can also provide tree and stump removal if that is the recommended option for your ash tree. Prompt removal is critical, as dead ash trees become brittle quickly and pose a safety risk.

Additional frequently asked questions about emerald ash
The emerald ash borer (EAB) is an invasive beetle from Asia. EAB was first discovered in the United States in 2002 near Detroit, Michigan, and has since spread throughout the country. It was found in St. Paul in 2009, and every county in the Twin Cities has infestations. EAB has quickly become one of the most destructive and costly forest insects in urban forest history.
EAB larvae feed on the inner bark of ash trees, which disrupts the tree‘s ability to transport water and nutrients. EAB populations can grow exponentially yearly because the beetle has few natural predators, and our ash trees have limited natural defenses. Once an ash tree is infested, it has almost zero chance of survival. Proactive treatment is the only proven and reliable method of saving an ash tree.
With an estimated 1 in 5 trees in the Twin Cities metro area being an ash tree, losing this many of them is comparable to a natural disaster with a significant environmental and economic impact. When EAB is not managed, annual ash tree deaths can quickly overwhelm the resources required to remove dead and dying trees. This results in a large number of hazardous dead trees, along with a significant financial burden to both property owners and cities.

The cost of treating your tree is based on the size of the tree. Tree size is determined by measuring the DBH (diameter of the tree at breast height, or 4.5 feet off the ground). Treatments typically range from $70 to $200 per tree in the metro area and are recommended every two years. Protection costs significantly less than removal and replacement, and you retain the value of a mature tree on your property.
Rainbow Treecare partners with over 35 cities and neighborhoods throughout the Twin Cities to treat public trees in parks and along boulevards. These partnerships also include a city-wide discount to private property owners. This discount program allows property owners to treat their ash trees at a reduced price. Find out if your city has a partnership with Rainbow Treecare!
The cost of removing a tree is based on several variables. A small tree with no obstacles may cost several hundred dollars to remove, while a large, hard-to-access tree near a structure can cost thousands. Unfortunately, trees in decline are more challenging and costly to remove. Stump removal is also an additional cost.
If you remove a tree, replanting is recommended. Depending on the size of the replacement tree and whether you hire a professional to plant it, tree replacement can cost between $50 and $400.
