Oh jeez, I just did it. Spent 1:43 minutes watching that video. Personally I could do without the preaching, though admittedly after a while I was starting to enjoy the repetitious opportunity to go top off my beer.
Seriously, though, yeah there's a lot of good information there. Especially if you're coming from the traditional roto-till and weeding method. I stumbled on this same technique where I had piled the chaff from splitting wood and then later needed a spot to plant some herbs close to the kitchen. I stuck them down into the soil below the chaff knowing it wouldn't grow there and had pretty good luck.
One comment on this method, I heard many times in the video where Paul talks about no inputs. Hats off to that guy and all he is doing, but there are still a serious amount of inputs. Cutting the wood, grinding it, hauling it, spreading it. If you have easy access to chips this would work great for you, but it wouldn't take long for this to catch on and the availability of chips to deplete pretty quickly. I much prefer a real no-input method- throw the seeds in, let it grow.
I had to really appreciate a part in the video about 2/3 through where Paul talks about putting too much work in, getting frustrated, and then quitting and going back later to start again. I had a day like that today and needed that reminder. Things are supposed to be easy and when we put too much effort forcing things that aren't supposed to be difficult it's time to take a breather.
Thanks for sharing that 4 seasons.
