A material designed to suppress unwanted plant growth by creating a physical barrier between the soil and sunlight, effectively preventing weed germination and hindering their ability to thrive. For example, a woven polypropylene sheet placed over a garden bed before planting flowers acts as this type of barrier.
The implementation of such barriers offers significant advantages in landscape management and agriculture. It conserves moisture in the soil, reduces the need for herbicides, and contributes to healthier plant growth by minimizing competition for resources. Historically, methods like mulching with organic materials served a similar purpose; however, modern materials offer increased durability and effectiveness.
