Use recycled wine cork keychains to create a charming border for your garden beds. Dig a shallow trench along the edge of your garden bed and place the cork keychains vertically in the trench. Backfill the trench with soil, ensuring the cork keychains are securely in place. The cork adds a natural and rustic look to your garden while also serving as a barrier to prevent grass or weeds from encroaching on your plants. This eco-friendly garden border is a creative way to repurpose wine cork keychains.
