Shown above is a time-lapse of a hand-dug hugelkultur mound.
Hugelkultur means mound culture in German. The wood/soil/compost mixture encourages mycelium growth which assists plants in nutrient absorption, and retains adequate soil moisture all year.
I chose this site as there is a convenient source of horse manure nearby and I had leftover branches from the thinning of mushroom logs. I even inoculated oyster mushroom spawn inside the exposed logs.
