These mats are designed to encircle a plant, letting air and water permeate while blocking sunlight from reaching the soil so weeds cannot take hold around the plant.
Each has a T-shaped slit to let you place it around the base of established plants or small trees; adding a layer of mulch is all that is required to secure it. Made from woven polyethylene, they can be reused for multiple growing seasons or left in place for up to four years.
Sold in packages of six ready-to-use mats in 15" or 23" diameters. An effective, chemical-free way to control the spread of weeds.
