When we moved in and had an arborist come cut down some of the plum trees we kept all the branches. When I was making my herb spiral I dug a hole to mix in compost and such and I buried some of the plum branches in a nod to Hugelculture. We also piled up most of them along the back wall and dumped dirt on it and hove things growing on it (oh, and an embedded hillside) in a more traditional hugelculture bed.
I enlarged it to include an attached bed for flowers.
I had a fantastic crop of borage, chamomile and comfrey plus some nice annuals this spring. I have prepared the bed for some new things but I’m not sure what. I already sprinkled some seeds randomly and put in a few ground cherries. There is also some lovely lovely smelling lemongrass and some valerian in there plus some basic herbs like rosemary and oregano.
Here it is June 2012:
