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.
I neglected my worms when I had my third child and was so sure they had died. 18 months later my worm tower was full to bursting with alive worms ready to be fed. It amazed me. 18 months without food and they continued their lifecycle without any inputs from me. It was a very happy day for me.
