4FT x 300FT Weed Barrier Fabric

The 4FT x 300FT Weed Barrier Fabric covers 1,200 square feet with a heavy 5.8 oz woven landscape mat.

This 4 ft wide by 300 ft long weed barrier fabric is built for serious landscaping work: long bed runs, large garden plots, pathway underlays, and commercial mulched zones. The 5.8 oz woven construction blocks sunlight to stop weed germination while staying permeable, so water, air, and nutrients still reach the soil below. Black UV-resistant fibers help the mat hold up under exposed mulch beds and full-sun areas.

Why this Weed Barrier Fabric works

• 1,200 sq ft coverage: One 4 ft x 300 ft roll covers most residential beds, walkways, and side yards in a single purchase.
• 5.8 oz woven build: Heavy weave resists puncture from sticks, root tips, and stake corners during install.
• Blocks weed growth: Opaque black fabric starves weeds of sunlight while letting moisture pass through.
• UV-resistant: Stabilized fibers handle direct sun exposure when used under mulch or in partial-cover applications.
• Breathable: Woven structure lets water, air, and nutrients reach plant roots and soil microbiology.
• Easy to cut: Sharp shears or a utility knife trim the fabric to any bed shape, including curves around shrubs and trees.

Frequently asked questions

How long will it last outdoors?
Service life depends on UV exposure and traffic. Under a mulch top layer, a 5.8 oz woven barrier typically holds up for multiple seasons. Direct sun exposure shortens service life, so cover with mulch, gravel, or stone where possible.

Will water and nutrients pass through?
Yes. The woven mesh is permeable, so irrigation water, rainfall, and dissolved nutrients pass through to the soil and roots. Roots can still access oxygen, which keeps plant health intact.

How do I secure the fabric?
Use landscape staples or pins every 12 to 24 inches along seams and edges, then weight down with 2 to 3 inches of mulch, gravel, or decorative stone. On windy sites, add extra pins around corners and seams.

Can I plant through it?
Yes. Cut a small X over each planting location, fold the flaps back, plant, then fold the flaps in around the stem before topping with mulch. This keeps the rest of the bed weed-resistant while making room for desired plants.
