The best way to keep your lawn healthy and green is to mow it regularly. Make sure you cut no more than one-third of the grass at any given time, and use a sharp blade for a clean cut. Water your lawn deeply but infrequently, allowing the soil to dry out before watering again. Aerate your lawn by pulling plugs of soil up from the ground with a spade or similar tool. Finally, fertilize your lawn every few months to ensure that it stays healthy and green.
