A layering technique where cardboard or newspaper is placed on existing vegetation, then topped with compost and other materials to create a new garden bed in place without digging.
In plain terms
Lay cardboard or newspaper over existing grass or weeds, overlap pieces, wet thoroughly. Layer compost, leaves, and aged manure on top (like lasagna layers). Water well. The bottom layer kills grass/weeds; the layered materials compost down into rich soil. You can plant immediately into top layers or wait 3-6 months for full decomposition. It's the lazy gardener's dream: new beds without digging.
Why this matters
Sheet mulching eliminates digging, kills existing vegetation, and creates rich soil in one process. It's ideal for lazy composters and quick bed creation.
In practice
Examples
New bed created over lawn: cardboard, compost layers, plant immediately in top compost; grass killed, new soil created.
Large area sheet-mulched: thick layers over two seasons; area transforms from weedy to productive.
Fall sheet mulching: by spring, materials mostly decomposed; ready to plant in rich new soil.
Weedy patch sheet-mulched: eliminates digging out weeds; new bed ready to plant next season.
Practical applications
Cardboard from appliances or grocery stores works great (remove tape and staples).
Overlap cardboard 6-12 inches to prevent weeds escaping edges.
Layer compost (2-4 inches), leaves, aged manure, compost again (builds height and nutrients).
Water each layer as you go; helps materials settle and decompose.
Plant into top layers immediately or wait for more decomposition; both work.
