No-Dig (No-Till) Gardening

No-dig gardening means you stop turning or tilling the soil and instead feed it from the top with compost and mulch. Soil life — fungi, worms, microbes — does the mixing for you, the way it happens in a forest floor.

Tilling destroys soil structure, kills fungal networks, and brings buried weed seeds to the surface to germinate. Leaving soil intact keeps it spongy, well-drained, and full of life, so plants root deeply and you pull far fewer weeds over time.

On an existing bed, lay cardboard over weeds and wet it down. Spread 2–4 inches of compost on top. Plant straight into the compost layer. Each season, add another inch or two of compost on the surface — never dig it in. Keep the soil covered with mulch or living plants year-round.

Quality compost is the engine of a no-dig bed, so source the best you can. Weeds that do appear pull out easily from the loose surface. It can take a season or two for the soil biology to fully wake up — the results compound year after year.
