The answer to 'how to maintain aeration' is to regularly aerate your lawn to improve soil health and promote grass growth. Aeration involves punching small holes in the soil to allow air, water, and nutrients to reach the grass roots more effectively.
For best results, aerate your lawn once or twice a year, typically in the spring or fall when the grass is actively growing. Use a core aerator machine to remove small plugs of soil, leaving behind holes that will help the lawn breathe. Be sure to avoid aeration during hot, dry weather or when the soil is very wet, as this can damage the lawn.
