Legacy Tree Project

Annual ash treatment to begin this week


About 200 ash trees in Worthington will receive their annual experimental treatment for the emerald ash borer this month.

Tree experts this week were expected to begin the application of a commercial product called Safari, which is provided at no cost to the city through the Legacy Tree Project, according to city spokeswoman Anne Brown.

The trees are on city property, either in the right of way along streets or in parks.

This will be the fourth of five annual treatments to the ash trees.

In 2010, Worthington was selected as one of a dozen Midwest cities, towns and villages to participate in the Legacy Tree Project, sponsored by Valent Professional Products.

According to Worthington service and engineering maintenance superintendent Tom Gilkey, the treatments seem to make a difference in protecting the ash trees from the deadly beetle.

"You can really see the difference between the LTP trees and the untreated trees in the immediate area," Gilkey said.

When the project was started in 2010, the city already was losing trees to the ash borer, so some of the trees being treated already were under stress, he said.

Applications are done by certified professionals from the Davey Tree Expert Co.

Residents living near the ash trees scheduled for treatment will receive fliers further describing the treatment.
