Scoria (Volcanic Slag)

Garden Natura Scoria is a volcanic-origin, high-durability natural mineral aggregate.

It is used in professional nursery production of seedlings, ornamental plants, olive and fruit saplings, as well as in landscaping applications to provide drainage, aeration, and physical support.

Thanks to its dense and hard structure, it maintains volume in mixtures and preserves its form over time.

Its porous internal structure increases air circulation around the root zone and helps excess water to drain away.

With these properties, scoria is ideal especially for high-drainage growing mixes and cool-climate production environments.
