That's a great question! Dealing with grass and weeds poking through your garden bench can be a real nuisance, ruining the tidy look of your outdoor space. The good news is, several effective and affordable solutions can create a permanent barrier. The best method often depends on your bench style, budget, and desired aesthetic.
For a long-term, low-maintenance solution, start by removing the bench and clearing all existing grass and weeds from the area. Then, lay down a quality landscaping fabric or heavy-duty weed barrier cloth. This material blocks sunlight and physically prevents growth while allowing water to drain. Secure it with landscape staples. For a finished look, cover the fabric with an attractive layer of inorganic mulch, such as pea gravel, crushed stone, or rubber mulch. These materials won't decompose and provide excellent drainage. Another popular option is using brick pavers or flagstones set on a bed of sand or dust, creating a solid and stylish patio-like surface under your bench.
If you prefer a natural look, consider smothering the grass with several layers of overlapping cardboard topped with 3-4 inches of wood chips or bark mulch. While organic mulch needs occasional replenishing, it's very effective. Whichever method you choose, ensuring the area extends slightly beyond the bench's footprint will keep the edges neat. With a simple afternoon project, you can enjoy a clean, weed-free seating area for years to come.
