I just love this. I watched it for the first time last week and was floored, mostly because I've doing beds exactly this way. I bought my first rototiller last spring, and before too long I decided I wasn't going to till the beds, but rather, till the paths and put the material up into the beds. I then mulch like crazy. When I saw that that was the technique in this video I almost fell over. I thought I had come up with it, turns out it a Fukuoka inspired method, and I had no idea. Anyway, it works very well for me, and I'd like to share. This year I might incorporate a bit more hugle into any new beds, but I'm sold on the technique for my kitchen garden. The other change I'd like to make is I'm realizing the difference the aspect of the soil makes. I'm going to try to tilt all my raised beds so the surface faces south, but maybe that's for another thread.
Enjoy!
