Pebbles are currently very trendy, with landscape designers using them as mulches, in mosaics and paving, and to surface paths and driveways. Using them in a garden brings different colors and textures to the garden. Pebbles can also fill up otherwise empty space in the garden, leaving a visual that might be considered more interesting and aesthetic than simple dirt, soil or mulch.
Moreover, it can serve other purposes, such as creating a decorative border or a landscaped path, providing a pretty ground and soil cover, and providing dry garden beds. Pebble a garden with a mix of pebbles and minerals that complement the vegetation in the yard.
