I also have a small patch to work with and it is so rewarding. I started reading about permaculture because I hated the idea of added npk fertilizers to make plants grow. It felt so unintuitive and daunting to me.
The moment I read about dynamic accumulation, soil life cycles and guilds it was like a bomb went off in my head. I was so excited I had to read everything I could. I love the idea of a mostly closed cycle and reusing as much of what the garden and my kitchen waste could provide.
