My garden is basically in 4 distinct sections and they even have micro climates - my backyard can be several degrees cooler in temperature than my front yard. My garden is roughly 90% California natives, but I also have a lemon tree, two apple trees, an olive tree (you must drink fresh olive leaf tea!) and a bottle brush which started growing on it's own. I garden for the pollinators and birds and any wild creature who wants to live there or travel through. Because I have at least 4 very distinct gardens I have one of these beautiful electro gardening stakes in each one. I move them around every few months as things grow, or die back for the season, or get trimmed back. It's fun to move them around as it connects me even more deeply, allows me to talk to my plants, flowers and trees asking them where I should move their copper helper to.
I plan to get more for my many potted outdoor plants to help them get more of Earth's magnetic medicine.
