Bill and Sal Worked for Mrs

Bill and Sal worked for Mrs.Greenlawn,a lawn-care company.One morning they attended at a new customer's residence.While in the process of applying fertilizer to the lawn,the boys mistakenly applied strong weed killer that caused the grass to turn brown and die.The boys failed to follow the employer's directive that they double check to ensure that fertilizer was being used.The owner of Mrs.Greenlawn apologized to the homeowner but indicated that it was not her fault and she would not be paying for the costs of sodding the entire lawn.Is the position taken by the owner of Mrs.Greenlawn correct at law?
