ABSTRACT:
A landscape material includes a plurality of fibers. Each of the fibers includes a generally uniform length, such as in a range of from about 3.0 inches to about 10.0 inches, and a generally uniform cross sectional area, so that the landscape material generally is lighter in weight and more uniform in appearance than landscape material of the prior art. The landscape material optionally includes an additive such as a colorant. A method for making landscape material is also provided. The method includes the steps of providing a wood section and cutting the wood section into a plurality of ribbons. Each of the ribbons has a generally uniform cross sectional area, and the ribbons are reduced to fibers, each of which has a generally uniform length.
