A core aerator is a gardening tool designed to improve soil health by creating small holes in the ground. It removes plugs of soil, allowing air, water, and nutrients to penetrate deeper into the soil. This process helps reduce compaction, promotes root growth, and enhances the overall health of lawns and gardens. Core aerators can be used on various types of grass and soil, making them versatile for different landscapes. They are often used in conjunction with other lawn care practices, such as overseeding and fertilization, to achieve optimal results. Regular aeration can lead to a lush, green lawn over time.
