From what I can understand, classical hugelkultur consists of piling up logs and branches, filling over with topsoil and planting on top. The decaying wood adds fertility and heat to the heap, which is good for the plants growing above, and it also provides some heat to the heap. I'd never heard of hugelkultur until I read about it on Craving Fresh , I thought at the time that it was an interesting concept, especially when we have such cold winters here, but I wasn't sure what to do with it. Then someone from our permaculture group sent around another link with some great pictures and I was even more interested, but still not sure what to do. The problem is that we lack topsoil as it is, and I wasn't going to buy any. We do have plenty of logs that are too big for the mulcher though, so I was still interested. Then we went to a permaculture techniques day with our permaculture group, and looked at some hugelkultur and swales at the Bottle Tree Hill Organics farm.
