A longtime Zanesville business is getting ready to close its doors. Northside Garden Center, in operation for the past 25 years, is going to be getting out of the retail business by the end of the month. Owner Don Melhorn says the plan to close has been in the works for the past two years. Melhorn says it’s getting harder and harder to stay competitive. Northside Garden center will close on June 30th. But, Melhorn says he plans to keep the wholesale side of this business going. Northside Garden center is located on state route 60, north of Zanesville.
