Product Description
Bioretention Soil Mix is a blend of 60% medium-fine sand like Fairway Top Dressing Sand and 40% fine compost. It’s used as a planting medium in areas that require drainage due to water runoff.

According to the Low Impact Development (LID) Toolkit for Local Governments, bioretention refers to “a shallow landscaped depression with a designed soil mix (the bioretention soil mix or ‘BSM’) and plants adapted to local climate and soil moisture conditions.”

Our blend is based on City of Seattle specifications.

Product Applications
Bioretention Soil Mix can be used in rooftop gardens, rain garden basins, and bioswales. It can also be used around retention ponds.
