For those that don't know, muck is a type is a self-adhering, clay like mud used in bonsai, kusamono, kokedama, etc. It mostly seves as a sort of molding/modeling clay for holding together mounds of actual substrate on rock slab plantings or plantings where you want to create a mound that rises above the lip of the pot. Most recipes I'm aware of use peat, LFS, and clay, but I would imagine that the minerals in the clay would not be good for CPs. I have a design idea for a dish/container bog garden that would really benefit from some muck, but I don't know of many recipes that use an inert substitute for the clay. I did find one that mentions using a corn starch slurry, but I'm not sure if it'll end up killing my plants. Any thoughts from you guys? Thanks in advance!
