To build a Hügelkultur bed, you’ll need a variety of materials that are readily available in most natural environments. Essential materials include logs, branches, and twigs, which form the core structure of the bed. You’ll also need organic matter such as leaves, grass clippings, straw, and compost to layer over the wood. Finally, a top layer of soil is required to cover the entire bed. Optional materials include cardboard or newspaper to suppress weeds at the base and rocks or stones to outline the bed’s perimeter. It’s important to choose untreated wood to avoid introducing harmful chemicals into the soil.
