Interesting title. Yes, it should attract a few people just based on the non english wording. Anyway, what is a Hugelkultur? Good question.
Well, in short I will say that it is a method of organic gardening using wood as a brown. To make a Hugelkultur you pile up branches or brush that is one to two feet deep/high and 4 to 8 feet long. Then, stomp on the pile to compact it. (I would actually dig a trench a foot or so deep and put the branches with so me grass in there.) Anyway, after stomping, put grass clippings and other compostables on top of the mound and top with an inch or two of compost then, dust with soil and plant with seeds or starts.
Apparently, potatoes love Hugelkultur (I just love typing that word ) Squashes, melons and other vining fruit thrive in this planting system as well. Also, with the mounding of the compostables, it creates more surface area to plant on.
And Rotting wood acts like a sponge to hold water. Therefore, less watering needed.
