Yep. They’re pretty much set up on Square Foot Gardening.
It’s a good system that works, in my experience. I refer to my book, often. Great planting time charts in it for extending the growing season with multiple plantings. :)
I’d like to go with it for some things like strawberries and other low growers but using untreated wood around here just doesn’t work and I don’t want to use treated wood. Moisture and termites destroy wood touching the ground in less than a year. Thought about molding up some concrete panels that attach together somehow. Just one of hundreds of things on my To Do list(s).
