Very rich and earthy. Dark, almost black in colour.

Best Suited For:

Well composted mulch that has been cooked for three weeks, making it a rich blend full of beneficial microorganisms to assist plant growth and root development. Great for water conservation, extremely attractive being naturally dark, almost black in colour without being artificially spray-painted. It highlights foliage colour by adding a classy edge to contemporary gardens.
