“Hügelkultur” is a German word meaning “hill culture,” or “mound culture.” A hügelkultur mound consists of a raised plant bed built up over decaying wood and other compostable materials. A practice that has been used for generations by German and Eastern European peoples, it is now getting some serious attention from permaculture aficionados for its excellent results.
I was not familiar with this but check out the Proven Winner post. It a great idea!
