An all natural soil conditioner manufactured by blending sawdust with Loop (Bio-solids-A byproduct of waste water treatment plants). GroCo™ is blended together and composted for over one year, during this time temperatures are recorded and the material is turned several times. Before sale the material is tested in compliance with Federal Code Of Regulations 40CFR-Part 503 and Washington State Department Of Ecology Regulations. Which includes Pathogens, enteric viruses, and heavy metals. GroCo™ contains many micro and macro nutrients that northwest soils lack, but are required for healthy growth of plants.

Application: As a soil conditioner, loosen the existing soil, spread 1” to 3” of GroCo™, and then till or spade into the soil. As a mulch spread 1” to 3” deep on flower beds and vegetable gardens. After several rain events or waterings, stir lightly with a rake to prevent crusting. As a mulch GroCo™ provides a rich, dark soil color. As a potting soil, mix 1/3 GroCo™ with sandy garden soil.
