What is pressure treated edging?

Pressure treated edging refers to landscape borders made from wood that has been treated with preservatives to resist rot, insects, and weathering. This type of edging is commonly used in gardens and landscaping to define spaces, create clean lines, and support soil retention. The pressure treatment process involves forcing chemical preservatives deep into the wood fibers, enhancing its durability and lifespan compared to untreated wood. As a result, pressure treated edging is a popular choice for long-lasting outdoor projects.
