FINDLAY, Ohio (AP) — A university in northwest Ohio is being forced to replace almost all its grass after weedkiller was accidentally applied to lawns instead of fertilizer.

University of Findlay spokeswoman Brianna Patterson said the chemical was applied to campus lawns during the last week of April and it will take several weeks to reseed and re-sod the affected areas.

Patterson told the Findlay Courier the mistake is unfortunate because of how hard the university works to keep the campus looking nice.

Findlay University did not release the name of the company that made the mistake but is working with the business’ insurance company to pay for it to be fixed.

The university says grass was killed on as many as 54 of the campus’ 72 acres.
