I feel like I'll be reposting this video a lot, but I love ✨LEAF MOLD✨
In my garden, I took some chicken wire, a few stakes, and made a place for leaves, about 3-4 feet across.
Just like compost, mix it every few days and moisten it to the level of a damp sponge (appropriate for your climate). After a year (yes, a year), you'll have a pile of broken down organic matter, and a lovely leaf mold environment.
Also, Leaf mold breaks down leaves way faster when you already have a starter pile of it to add to from last year.
