The Mitzels of The Prepared Homestead have a couple of videos on their Youtube channel about victory gardens. Their homestead is a colder zone in Idaho. They give a little history of victory gardens, how supply chains work and why you would have a garden yourself. In the part two video, they get into how to start, what to grow, how to read seed catalogs and so forth. If you aren’t familiar with the Prepared Homestead already, they have a lot of herbal and permaculture knowledge in addition to what they’ve learned homesteading.
