PERMACULTURE ** Design Principle #6 – Make MINIMAL CHANGES to achieve MAXIMUM EFFECT when working to improve a system

This principle makes great time and energy saving sense, but first, before I could put it into practice I had to understand what was meant by a “system”. To understand the term “system” in a gardening context, it helps me to think of the human body and the integrated systems that keep it functioning.  The digestive, nervous and immune systems all work together to sustain one living organism. Gardens, orchards, neighborhoods and cities flourish when viewed as integrated living systems rather than isolated, separate, unconnected components.

After wrapping my brain around what a “system” was I started experimenting. Observation of those experiments made it possible to identify key leverage points. I then made a few changes to get the maximum benefit from each system. These changes altered how each system worked together to support the productivity of the whole garden. This is not a onetime deal. I’m always looking for ways to simplify, improve and streamline systems to create sustainable integrated gardens, fruit tree guilds and wild lands.

Often, when moving to a new garden location the systems that have been installed before our arrival are not designed to support sustainable gardening efforts. This was the case when I converted the existing 660 square foot backyard lawn into a vegetable garden. The lawn had a conventional pop-up sprinkler system installed which sprayed precious water into the air to be carried away by evaporation while creating an unhappy environment for veggies that do not like wet leaves. Happily, through the UC Master Gardener program, I had a class on irrigation options. I discovered I could convert the existing sprinkler system to drip line irrigation. With limited expense, using the existing pipes and timer, I was able to revamp the system to meet the needs of my vegetable garden. Considering the effort and waste of installing a whole new irrigation system I was happy to make this relatively small change that had a big effect on the amount of water being used and the overall health of the vegetable garden.

Identifying systems, observing them and making minimal changes for maximum benefit has made gardening easier and more productive for me overall!
