I think it's great you did this experiment and found out the technique is not for you. That's one of the keys to
permaculture, maybe even a principle, to try different things and see what works for one's own situation. I have pondered these beds myself and can't see where I would put them in the landscape of my
yard. I've hauled literally tons of rocks making my buried wood kitchen garden, so the hauling of the rocks just seems like regular work to me anymore. It would probably be easier to stack the rocks than to dig them up in the first place. I think this would be useful in a place where there were lots of flat rocks lying around, or in an urban area with broken slabs of
concrete to use. My
experience with any kind of untreated wood construction touching the earth is it will rot away in only a few years. And I'm not personally keen on the idea of treated wood near food plants, so for me, wooden raised beds don't make sense in my situation. I've found raised beds tend to dry out pretty fast here unless they contain a whole lot of buried wood. Did you find this raised bed dried out faster than non-raised beds? Or did it hold
water better?
