Mature compost, What is mature compost?
Thursday, 10 October 2013 | HOTBIN Composting
Mature compost is crumbly and dark brown and you should not be able to identify the former materials (eg a banana skin, leaf, etc). It should smell earthy / musty.
It is said to be mature, as the majority of bacteria are no longer active, (they have consumed what they can).
