I am really loving the hugelkultur principle & method! The more information I can acquire for my soon to be mine homestead, the better. This is truly intriguing! Question: I just may not have come across it, but does hugelkultur require mounds? OR can you simply bury the wood? I'm getting this from the video I'm sharing, but often I see mounds. Can it be preference & what you have to work with in regards to space/land? Thanks! --Tess
