Black Gold Natural & Organic Potting Mix | 1cu ft - OMRI Listed - 70/PL

Earthworm-Enriched Organic Potting Mix, 1cu ft

A bagged potting mix that skips organic matter and biological activity tends to compact over a season and needs more frequent feeding to keep container plants healthy. Black Gold Natural & Organic Potting Mix builds a base of peat moss and compost, then adds earthworm castings on top of that for extra natural nutrient content, aimed at containers and raised beds that benefit from richer, more biologically active soil.

This 1cu ft bag also contains perlite and pumice for aeration and carries OMRI Listed certification for organic gardening.
