An "Edger" is a gardening tool used to create clean, defined edges along pathways, flower beds, and lawns. It helps maintain a neat appearance by cutting through grass and soil, preventing overgrowth and encroachment of plants into unwanted areas. Edgers can be manual or powered, with electric and gas options available for larger tasks. Using an edger can enhance the overall look of a garden or yard, making it easier to manage landscaping. Regular edging can also promote healthy plant growth by reducing competition for nutrients and water. Proper use of an edger contributes to a well-maintained outdoor space.
