Several years ago I put in several traditional raised beds on top of our hard clay soil. These worked well but they didn't produce nearly as well as the woody beds I created after learning about hugulkulture. So this fall I picked up some alleve and went to work converting my raised beds to hugul beds:

This experience  taught me the value of clay and how it can be a super valuable addition to your soil composition. Has anyone else on the forum converted their beds? It's a lot of work but the long term value will be huge!

I just built a new raised bed on top of some rotten logs. Since it is built on a slope, it allowed me to fill the space on the bottom with chunks of wood, where a soil could be wasted.
The exposed rocks, that the frame is resting on, also serve as heat accumulators.









I am preparing it to be a cold frame and grow some greens in early 2017.
