Is that to say a colonized substrate that fruits mushrooms and excretes plant beneficial secondary metabolites while breaking down organic matter isnt alive?
IMO planting the proper fungi/w organic matter, is far more beneficial than any plant life you could pair with your garden.

I believe were talking about the mulch being alive, as in growing plants to feed the target plants. And whether the mulch is alive or dead the soil is alive fo sho. And I have to believe organic mulch provides more life than perlite, although perlite does look nice and tidy, I'll concede that.....scrappy
