Bare Earth

• A simple solution involves leaving bare earth between the stones. This can work as planting beds, with flowers and other greenery planted in between and around the stones. The walkway enables a gardener to get to the plants without having to walk on the bare earth.
  
  

Grass

• Allowing grass to grow between the stones of a walkway provides a garden with a lawn. Arranging the stones to lead to entrances, exits and features in the garden ensures that people will use the path. This protects the grass infill from the wear and tear of people walking on it, which helps to keep the lawn in good condition.
  
  

Wood Chips

• To provide a garden with a rustic appearance, wood chip infill material can prove a good choice. This material is attractive and releases nutrients to the plants as it slowly erodes over time. Wood chips also absorb water, and will subsequently release this to the soil below.
  
  

Stone Chips

• Stone chips can provide a garden with a variety of different looks, depending on the type of material used. River stones have a smooth, rounded appearance, while material such as slate and marble, has a more angular appearance. Stone chips also come in a variety of colors, and while this can include natural browns and greens to blend into a garden, blue and red colors can provide a splash of color around a walkway path.
  
  

Crushed Glass

• Crushed glass can provide a more unusual look for infill material. This lends itself well to landscaping a small area around the stones of a walkway, and can provide a distinctive, contemporary appearance. Care should be taken not to overuse this material, especially in homes that have younger children.
  
  

Sand and Gravel

• Using sand and gravel materials as infill around walkway stones can create a Japanese garden style. This can produce a minimal appearance for a garden, although raking the sand and gravel into patterns can provide an overall attractive look.
