carrots don’t get tall….but, it’s alot easier to grow them in raised beds where you can make the right soil, or…....
you can till up a particular section in the “big” garden and do exactly the same thing.
Additionally, if you don’t give climbing things something to climb they don’t climb. If you do then they cllimb. I can give my beans something to climb in the “big” garden just as easily as I would in a square foot.
Why use soil at all? Why not use hydroponics? Why not grow tomatoes upside down….
As I said before no single system is perfect. There’s always a particular system that will suit the individual and his or her situation. sq.ft. is one particular organized system. So is hydroponics, so is row cropping. If it works for you, then use it.
But then I haven’t met a book yet that I couldn’t reduce to about one tenth it’s size by editing out all the fluff. I don’t like paying $20 for a 200 page book that has about 20 or so pages of useful info.
