Hugelkultur is raised garden beds that reduce or eliminate the need for irrigation and fertilizer.
This video shows the why and how of this type of raised garden bed. Hugelkultur can be built by hand or with machinery; urban lots or large acreage farms. The focal point of this video is a project in Dayton, Montana where Sepp Holzer installed nearly a kilometer of hugelkultur beds in early May of 2012. Then the video shows the results in mid September.
Michael Billington is currently the land manager there. He explains how the beds have not been irrigated and goes into some detail of the qualities of the food from the different aspects of the hugelkultur: the north side tends to be sweeter and the south side tends to have more bite (lettuces tend to be more bitter and mustards tend to be hotter).
