How to Start a No-Dig Garden
The short answer
To start a no-dig bed, don't dig at all: mow or chop the existing grass/weeds and leave them, cover the whole area with 4-6 overlapping layers of plain cardboard or newspaper to block light, then pile 3-4 inches of compost on top and finish with a few inches of mulch (straw or wood chips). Plant straight into the compost. The cardboard smothers the weeds and grass below, and the layers break down into rich soil.
No-till keeps the soil's structure and life intact, builds organic matter, holds moisture, and means far less weeding — because you never bring buried weed seeds up to the surface. Each season you just top-dress with more compost.
How to build a no-dig bed
- 1Knock down the growth — Mow or trample grass and weeds where the bed will go; leave the clippings in place.
- 2Lay a light-blocking layer — Cover the ground with 4-6 layers of cardboard or newspaper, overlapping edges well, and wet it down.
- 3Add compost — Spread 3-4 inches of compost over the cardboard — this is what you plant into.
- 4Mulch the top — Finish with a few inches of straw or wood-chip mulch to hold moisture and block new weeds.
- 5Maintain by top-dressing — Each year add more compost/mulch on top — never dig or turn it.
✔ Build it in fall if you can, so the cardboard and layers have all winter to break down before spring planting.
Why it works
- Keeps soil structure, fungi, and earthworm channels intact.
- Buries weed seeds too deep to germinate and smothers existing weeds.
- Adds organic matter and holds moisture like a big mulch.
- Less work: no digging, tilling, or constant weeding.
