The answer to 'best lawn care' is to follow a comprehensive lawn care regimen that includes mowing, watering, fertilizing, and aerating your lawn on a regular schedule. This will help maintain a healthy, lush lawn that is resistant to weeds, pests, and disease.
Mowing your lawn to the proper height (3-4 inches for most grasses) and using a sharp mower blade will encourage deep root growth and a dense turf. Watering deeply and infrequently (about 1 inch per week) promotes drought-tolerance. Applying the right fertilizer at the right times of year provides essential nutrients. Aerating the soil annually helps oxygen, water, and nutrients reach the roots.
