Hi Permies,
Here is another hugelkultur construction photo-tutorial (I am just sharing experiences, not teaching):
Data: Area 1 m x 2,20 m; Depht 30+ cm; Height 60+ cm.
Brown (Carbon): wood from apple, prunus, maples and figs.
Green (Nitrogen): a brush pile of bushes, vines and green tree prunings from the garden. I also added 5 Kg of dry organic manure for extra NPK.
Mulch: grass clippings (I am going to add wood chips and grass clippings when needed through the season).
First sowing: a lot of snap beans (N-fixers). In July I am going to transplant a big population of brassicas among the dying beans.
I am sure you know that the big plant in the foreground is a Mullein. It is a big guy and takes one of the best spots in my small garden, but I could not get rid of it. I'll let it bloom.
