Keeping the area under your outdoor benches weed-free doesn't have to be a constant chore. The best approach combines a physical barrier with a decorative top layer. Start by clearing all existing weeds and grass. For a highly effective solution, lay down a quality landscaping fabric or woven geotextile. This material blocks sunlight and smothers weeds while allowing water to drain. Secure it with landscape staples.
On top of the barrier, add a 2-3 inch layer of mulch, gravel, or crushed stone. Organic mulches like bark chips suppress weeds and improve soil as they decompose, but need replenishing. Inorganic options like pea gravel or river rock are longer-lasting and provide excellent drainage. For a natural look, consider using ground cover plants like creeping thyme or sedum in the surrounding area to outcompete weeds.
Avoid using plastic sheeting, as it traps moisture and causes drainage problems. For a permanent bench, pouring a concrete or paver base is the ultimate weed-proof solution. Regular maintenance, like quickly removing any sprouting weeds, will keep your seating area tidy and inviting all season long.
