These landscape features, typically constructed from materials like plastic, metal, or wood, serve as circular borders around the base of trees. Their primary function is to create a defined planting area, separating the tree’s immediate environment from surrounding turf or landscaping. For example, a homeowner might install one of these structures to contain mulch and prevent grass from encroaching on a newly planted sapling.
The significance of employing such borders lies in their ability to protect trees from lawnmower damage and weed trimmer contact, thereby safeguarding the trunk’s delicate bark. Furthermore, these structures aid in moisture retention by creating a basin effect that concentrates water near the root system. Historically, similar bordering techniques have been employed in landscaping and agriculture to improve plant health and maintain organized garden beds.
