Spike 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. Spike aerators can be manual or powered, making them suitable for various garden sizes. Using a spike aerator is beneficial for lawns and gardens that experience compacted soil. Compaction can hinder plant growth by limiting access to essential resources. Regular aeration helps maintain a healthy lawn and encourages a thriving garden ecosystem.
