If this looks to you like a mirage (or a Photoshopped photo) you're not alone. I could hardly believe my eyes when I opened the following video of a sub-irrigated rain gutter garden. Well, it's not a mirage and this "edible Garden of Eden" is located somewhere in the California desert. It looks a bit like a lunar landscape.
If you're wondering about the structure, it makes the garden safe from desert animals. Wait until you see what's inside. I'm sure the local animals salivate when they see the green feast beyond their reach.
It baffles me that all of the rain gutter SIP gardens I've looked at are in the country or suburbs. I've seen none in the city where lush, productive gardens like this are precious assets. It seems that gardeners outside our cities are better able to think on their own and garden outside the box so to speak.
The only urban rain gutter garden I know of in NYC is the one we built on the PS 133 Urban Green Campus. If anyone has information about an urban sub-irrigated rain gutter garden please share it with us.
This video does a good job of showing the piping and connections. As you will see, it is really quite simple.
