I also try to put a minimum of effort into the garden and do not use chemical control agents. Now I am harvesting beans, they have grown a little smaller than their seeds. But I didn’t fertilize it with anything and, apart from weeding a couple of times, I didn’t do anything to it. Good harvest.
Beans went crazy this year for me.
But I fertilize. Even the beans.
I have access to a lot of animal poop, though.
