Workflow
Lay Log Core and Branch Layer
1 dayStack hardwood logs (maple, oak, alder) 60 cm deep; fill gaps with branches and brush.
Apply Sheet Mulch Layers
1 dayLayer manure, compost, grass clippings, and topsoil over wood core; water each layer.
Plant Guild and Monitor Settling
1 dayPlant nitrogen fixers and heavy feeders first year; top-dress with compost as bed settles.

Hugelkultur Layer StackTable
Standard layer order from bottom to top.
| Layer | Material | Depth (cm) | Purpose |
|---|---|---|---|
| Core | Hardwood logs | 60–90 | Water retention |
| Gap fill | Branches, brush | 15–30 | Structure |
| Nitrogen | Manure, grass | 10–15 | Offset C:N ratio |
| Topsoil | Compost + soil | 15–20 | Planting medium |
Bed Volume FormulaFormula
Volume (m³) = length × width × height — procure 40% logs, 30% fill, 30% mulch/soil by volume.
Wood SelectionStandard
Use hardwood (oak, maple, alder) — avoid black walnut (allelopathic), cedar (slow rot), and treated lumber.
Rotten Is Better
Partially rotted wood holds more water and does not steal nitrogen — seek logs already colonized by fungi.
Steep Sides
45° side angle maximizes planting surface area and prevents flat-top water pooling.
Termite Risk
In termite-prone areas, keep hugel beds away from house foundations — use well-rotted wood only.
Safety Notes
- Moving logs and building tall beds is physically demanding — use proper lifting technique and get help for heavy logs.
- Never use pressure-treated or painted lumber in hugelkultur — chemicals leach into food crops.
