General Organics Diamond Black

Diamond Black™ is derived from mined Leonardite, a naturally occurring form of carbon drawn from prehistoric peat bogs.

Containing an exceptionally high percentage of plant-active humates, Diamond Black™ supports beneficial microbial activity in soils and may increase micronutrient availability. Diamond Black™ can be added to all kinds of garden soils and potting mixes and used with a wide variety of plants during all phases of growth.
