An over application of Scotts Turf Builder Lawn Food may cause damage to your lawn. Two things will determine the extent of the damage - the amount of excess product that was applied, and the temperatures you are experiencing. The best way to help minimize the damage to the treated areas is to water the lawn 2 to 3 times each week for the next 3 to 4 weeks, for 30 to 45 minutes each time. Continuing to water will help the lawn get through the stress of an over-application and encourage recovery. You may want to check to make sure your spreader is calibrated correctly if possible. We want you to be confident in our products. For this reason, we offer a product guarantee to our consumers. At your earliest convenience please contact us to see what can be done.
