Scoria is a volcanic rock that is highly porous which has been formed from rapidly cooling lava. The high surface area of the rocks allows moisture and nutrients to be absorbed while also remaining porous. Scoria works well to add aeration and drainage into potting mixes, mediums or soil as an additive.

This is the Black version of our Scoria which is a dark charcoal grey colour when dry and black when damp. We also have Red Scoria available.

Scoria can also be known as Lava Rock. Scoria is similar to Pumice but is slightly heavier.
