Should local governments prioritize private partnerships to preserve historic trees on public property?
Bluestone Tree service treated a landmark 80-foot pin oak tree at the Monroe County Courthouse in Bloomington on October 9, 2026. The care aimed to improve the health of the 96-year-old tree after its companion tree split during a storm two years ago.
Why it matters
The soil at the site is alkaline, which prevents the pin oak from absorbing vital nutrients and water. Remediation is necessary to maintain the tree's health and prevent further loss following the death of its counterpart.
The pin oak stands over 80 feet tall and is approximately 96 years old. Soil samples analyzed in Omaha, Nebraska, confirmed that alkaline levels were inhibiting the tree's ability to thrive.
The players
Bluestone Tree service
An arboricultural firm that provides professional tree health assessments, soil remediation, and preservation services.
Monroe County Courthouse
A historic public site in Bloomington that serves as the grounds for significant landscape features and local government.
The details
Workers from Bluestone Tree service aerated the compacted soil surrounding the tree's root system to allow better oxygen flow. They then applied a nutrient-rich mixture of mulch, biochar, and compost to balance the soil chemistry. In future phases of the treatment plan, arborists will inject iron directly into the trunk to further assist the tree with nutrient uptake.

The Home Front
Managing tree health is a critical component of local property maintenance, especially when dealing with mature specimens sensitive to soil alkalinity. This intervention follows the standard arboricultural practice of soil remediation for alkaline-sensitive oaks to mitigate environmental stress.
If you have mature trees on your property that appear to be struggling, consider scheduling a soil analysis to check for pH imbalances. Consult with a licensed arborist to discuss non-hazardous aeration or amendment options that can support long-term canopy health.
The takeaway
Proactive soil care is essential for extending the life of mature trees in alkaline-prone landscapes. Homeowners should observe their trees annually for leaf discoloration and contact a local arborist if they notice a decline in canopy density.
