Plant Health Care
Preventive care for Minnesota's biggest tree threats, planned around the seasons and your trees.
How we approach plant health care
Plant health care is where we spend our quietest, most valuable hours. We protect ash trees from emerald ash borer with trunk injections every two years, prevent oak wilt spread with root graft barriers and careful timing, and improve compacted city soils with air spading and organic amendments.
Treatments are chosen to be targeted, not blanket. We use trunk injection and soil applications that keep products inside the tree instead of drifting into gardens, and we monitor with seasonal visits so we only treat what needs it. Most clients enroll through a care plan.

Why it is worth doing right
What affects the price
Every tree is different. These four things move the number the most.
- Trunk diameter
- Injection pricing is based on diameter at breast height.
- Treatment type
- Soil programs and root barriers differ from injections.
- Number of trees
- Multiple trees per visit lower the cost per tree.
- Care plan
- Plan members save 10 to 15 percent on treatments.
