3 forms of composting in one picture ->
1) Vermicomposting tower: 4 layers with mixtures of cardboard food and clippings. Goal is to let them break down the materials while also producing worm castings that are great for the garden - I've been mixing them with water to uppot things
[ID: 4 visible levels of a black tower, with an open spigot at the bottom pouring into a purple gardening can]
[ID: Worm castings on top of visible grass clippings and worms]
2) Compost ball: Provides an enclosed space that insects & moisture can move in and out of but rodents and my dogs cannot. I use this to break down any food items until they're no longer desirable to any mammals, and then layer them into the main compost pile
[Blue sphere with a closed lid and small holes in it, surrounded by grass clippings and with long dried stalks to its right]
3) Main compost: Shallow hole filled with successive layers of leaves, cardboard, grass and weeds, straw, biochar, decomposed food, broken down stalks and very old wood, and sometimes manure if I have access to any that needs aged.
[ID: A black multi-level worm composting tower on the left, a large pile with cardboard and grass clippings visible in the center, and a blue sphere on top of that with holes throughout.]
