I love the idea of a food forest, when my wife and I moved into to our property several years ago we started buying foraging books for edible and medicinal uses an it turns out there are hundreds and thousands of plants that grow wild out here to eat and use. In the spring and summer we can pretty much live off the land with the help of our garden but then storage becomes an issue in the winter along with less growth. Thanks for posting that video it was pretty cool, also I have gotten a lot of information from plantabundance and edible acres on YouTube if anybody else was interested in this kind of thing
We've been trying to invest in jarring supplies for if or when our local shelves become empty but the stuff is kind of expensive!
