Edging
Hardwood is commonly used for the edging of gardens or paths. It provides a transition between the soft and hard elements.

Edge boards are typically fixed to driven timber pegs. Timber edging may be run in straight lengths or curved to suit the design. For tight turns the inside face of the edging may be notched to assist installation.

Since the timber is in contact with the ground it is exposed to high decay hazard and therefore requires consideration of its durability.
