It is important to follow the manufacturer's instructions for the specific fertilizer you are using and to water the lawn thoroughly after applying fertilizer to help it absorb the nutrients. Additionally, regular mowing, aeration, over seeding, weed control and soil testing can all help to maintain a healthy and beautiful lawn.
