Wood Fiber Mulch

Rainier Fiber Mulch

Rainier Fiber is a 100% wood fiber mulch made for use in hydraulic planting.  The mulch is made from clean, fresh-cut Western softwood chips. The fibers are separated by a thermo-mechanical process using high temperature steam and a rubbing action through a defibrator.  The combination of clean wood chips and heat produces the best sterile and toxic-free mulch for germination and growth of seed, stolons and sprigs.
