What Are My Choices if I have an Ash Tree?
If you have an ash tree, now is the time to decide what to do. Ash trees can either be protected or removed. Rainbow recommends that homeowners treat large, well-placed, healthy private ash trees to preserve our urban forest, One Tree at a Time.
Considerations for Treatment:
- Is the size of your tree is greater than 10” in diameter?
- Is your tree competing with other trees or infrastructure?
- Does your tree show no more than 30% of canopy decline if an infestation is suspected?
Did you know?
- 1 in 5 trees in the twin cities is an ash
- One mature ash tree will intercept 2,216 gallons of storm water in one year
- Trees can increase property values by 20%

The loss of ash trees would make a substantial impact to our urban environment. Additionally, treating an ash tree is more cost-effective than removal. Best of all, you maintain the tree benefits and value of a mature tree to your property!
