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 overall lawn and plant health. Core aerators can be used on various surfaces, including lawns and sports fields. They come in different types, such as manual aerators and powered aerators, making them suitable for both small and large areas. Regular aeration can lead to a greener, healthier landscape.
