No-dig gardening: building beds without tilling

No-dig gardening skips tilling or double-digging in favor of layering organic matter on top of the existing ground and letting worms and soil life do the mixing. It disturbs soil structure far less than digging, and for many home gardens it is also simply less work.
The idea behind it
Undisturbed soil keeps its structure, its fungal networks and its population of worms and microbes largely intact. Digging or tilling breaks that structure up every time, which can improve a badly compacted bed once but does ongoing damage if repeated every season.
Starting a new bed
Lay cardboard or several sheets of newspaper directly over grass or weeds to block light and smother them. Cover it with several inches of compost or well-aged manure — deep enough to plant straight into (six inches or more works well for most crops). The cardboard breaks down within a season.
Maintaining it year to year
Instead of digging the bed over, top-dress with an inch or two of compost between crops or at the start of each season. Avoid walking on the beds — keep dedicated paths — since compaction from foot traffic undoes much of the benefit.
Where it works less well
Heavy clay that badly needs one-time amendment can benefit from an initial dig-in before switching to no-dig maintenance. Converting a large area fast also usually calls for some tilling; no-dig tends to suit converting and maintaining beds one at a time.
