Permaculture takes inspiration from naturally occuring patterns and systems.
It is an ethical design approach which aims to create abundant, healthy, and harmonious landscapes which meet the needs of people and the earth's ecosystems.
Gardening with permaculture principles includes:
working with nature so that nature can work for you
creating and using microclimates
encouraging a rich diversity of plants
using passive energy systems
designing low maintenance structures and grounds
self sufficiency and minimising external energy needs
water conservation
