Sheet Mulching
A no-till method for converting lawn to bed.
Sheet mulching is the difference between killing your lawn in one weekend and killing your back killing your lawn. It uses cardboard, compost, and patience — and the result is better soil than you started with.
Sheet mulching is the lazy gardener's superpower, and the no-till purist's preferred method, all in one. It converts lawn or weedy ground to planting bed without digging, without herbicides, and without disturbing the soil biology you already have.
Step one: cut the existing vegetation low. A lawn mower on the lowest setting is enough. Leave the clippings in place — they're free organic matter.
Step two: water the area deeply. The soil and grass underneath the cardboard need to be wet when you start, or the decomposition stalls.
Step three: lay cardboard. Plain corrugated cardboard, no tape, no glossy printing. Overlap the seams by at least six inches — this is the most common failure point. Weeds find any gap.
Step four: water the cardboard until it's saturated. It should darken visibly.
Step five: top with 4 to 6 inches of compost or a compost-mulch mix. Not bark mulch — actual compost. The roots will use it.
Step six: wait six to eight weeks if you can. The cardboard breaks down, the grass dies and feeds the soil, and you can plant directly through the softened cardboard with a knife or trowel. If you're impatient, plant immediately by cutting an X in the cardboard at each planting hole — it still works.
