To maintain your lawn on your own, follow these steps:- 1. Mow regularly, avoiding cutting over one-third of the grass's height. Adjust the mower height based on the grass type and season. 2. Water deeply and infrequently to encourage deep root growth. Water in the morning to prevent evaporation and fungal growth. 3. Apply slow-release fertilizer according to the season and grass type, being careful not to over-fertilize. 4. Remove weeds by hand or use herbicides that don't harm the grass. 5. Promote root growth and alleviate soil compaction through lawn aeration in the spring or fall when the soil is moist. 6. Reseed bare or thin spots in the lawn in the spring or fall. 7. Determine soil pH level and nutrient content through soil testing. Amend the soil as necessary to ensure proper grass growth.
