ABSTRACT:
A landscaping system for the building of retaining walls for decorative borders comprised of landscaping units which are interlocked and secured together to form various regular and irregular formations. The landscaping units include two identical timber members which are fastened together in an overlapping, but longitudinally offset, relationship, which thereby define a projecting portion which extends outwardly at each end of the unit. In forming the designs, the projecting portions of different units are overlapped and joined together to form the border or wall.
