How it works

Mould

White mould blooms on fresh organics and leaves; springtails eat it.

New jars usually fuzz white in the first weeks.
Fallen leaves and leafy or bark top dressings keep feeding it, and it creeps to the ground beside.
White mould is harmless to plants.
Springtails graze it down; without them it can cover a fifth of the floor.
Grey mould is a disease of weak plants in still, damp, dim jars.
