I was very glad to read, in this Permaculture Explained article, that part of the principle of 'obtaining a yield' is ''enjoyment''... so no matter what it looks like, how well its done, what anyone else thinks.... if you like it, you get enjoyment from doing it or looking at it... you're a success. This does make me happy because part of my garden is flowery, shrubby, pretty, with a path... and I love it, so now I can also explain it as productive, because it produces Enjoyment. Happy. 😁
Heather Jo Flores, author of Food Not Lawns, runs a free permaculture course(which I am following) and also a paid diploma course, online. Here are a couple of links for examples of that course.
