A compost (pronounced “compohst” in Americanese) heap is a thing of true beauty.
We have 3.
One that’s active – sling in any organic matter from the kitchen, grass clippings, vegetation from the garden after it’s been through the garden shredder
One that’s composting with the help of a large families of worms, bacteria and other micro-organisms
One that’s turned everything in the first heap into a nutrient rich friable end-product.
Sieve it to remove the bits that haven’t decayed (they go back to the first heap…), mix with commercial potting mix 50:50, plant your lettuce plugs and jump back to avoid getting hit as they start growing instantly.
