Jim Cortese and Tom Perry, arborists with Cortese Tree Services in Knoxville, donated their time to perform an experimental injection of sugars into Toomer's Oaks in late March. If you live around here, you may have heard a few radio commercials for Cortese discouraging people from practicing tree topping . . . these are real tree people, not just someone selling something.
Cortese is a UT Forestry alum. A full update on Toomer's Oaks can be found at the link below (the injection slide says 2011, but the news articles indicate this just happened).
