Welcome, neighbors. In 2011 it occurred to me, as I heard more and more about the Emerald Ash Borer making its way closer and closer to Columbus that we have 43 large ash trees on our street. It quickly became apparent that if someone didn’t do something about it, we might lose the trees. I spoke to arborists, etymologists at Ohio State, a botanist, a micro-biologist and several other scientists. I finally got into contact with the gentleman who headed up the Emerald Ash Borer task force in Ohio. Incredibly, through all my research, I learned that although there are many invasive and costly treatments out there that require special certification to perform, studies showed that a soil drench treatment, that can be performed by homeowners, shows just as much efficacy against the EAB as the other treatments. I am happy to report that our efforts have been effective and our trees are healthy two years later.

I think we have created a streamlined and cost-effective process that anyone can execute, and I would love to share the process with other residents. The cost ends up being about $2-4 per tree, but the key is to mobilize, because the cost-effectiveness only comes into play if 25-50 trees are treated (and the chemical is bought in bulk).

Please do not hesitate to email me at cmcolucy@hotmail.com if you are interested in organizing a group. I have dealt primarily with trees in the city right-of-way, but I strongly encourage residents to treat their yard ashes at the same time. Any ash tree left untreated has a death sentence. The clock is ticking, folks. Our trees are part of what makes Clintonville Clintonville, and we are the stewards of our trees.
