I garden with many different methods and never really stick to one, but if you're into organic gardening then sooner or later you're going to come across permaculture.
The wikipidia definition of permaculture is:-
"Permaculture is a set of design principles centered around whole systems thinking simulating or directly utilizing the patterns and resilient features observed in natural ecosystems. It uses these principles in a growing number of fields from regenerative agriculture, rewilding, community, and organizational design and development."
