Manual aerators are gardening tools designed to improve soil health by creating small holes in the ground. These holes allow air, water, and nutrients to penetrate deeper into the soil, promoting better root growth for plants. Manual aerators typically come in two forms: spike aerators, which use pointed spikes to puncture the soil, and plug aerators, which remove small plugs of soil to create space for air and moisture. Using a manual aerator is a straightforward process. Gardeners push the tool into the soil, either by stepping on it or using a handle, and then pull it out to create the necessary holes. Regular aeration can enhance the overall health of lawns and gardens, making it an essential practice for maintaining vibrant grass and plants.
