I may be picking your brain about gardening and canning. I've only done herbs, which are easy because they just grow like weeds. I haven't done any vegetable gardening other than a few things many, many years ago.
I have almost no yard so I am very limited. I have been reading and watching Youtube videos on Square Foot Gardening. That seems like the way to go for me and that's not likely to produce a whole lot of each thing but, maybe enough to can some of it.
I want to be able to move out of the suburbs when I retire (hopefully in 8 years) and garden more.
