When I started my aquaponics setup, I dug a smallish (4 foot x 8 foot x 3 foot)
pond. Ended up using a different tank so I decided to use that for
hugelkultur. I filled it with wet logs and decomposed matter, mostly oak limbs and bamboo. Next, a friend and I built a retaining wall out of 2" hickory lumber from a
local mill. Filled that with a dead oak that was razed a year ago. Next I put a bunch of hedge trimmings on top until they were mounded slightly above the bed. I'm adding
compost and manure, though I only have one bag of each so it won't go far. Anyway, it is off to a start.
