How can I effectively use mulch for garden paths to enhance the aesthetics and functionality of my outdoor space?

To effectively use mulch for garden paths, spread a layer of mulch about 2-3 inches thick on the path. This will help suppress weeds, retain moisture, and create a neat appearance. Choose a mulch that complements your garden's aesthetic, such as wood chips or gravel. Make sure to replenish the mulch as needed to maintain its effectiveness and appearance.
