Learning garden layout.

I am in 8a/8b in southwest France and thinking about the upcoming season.

So far, I have planted my crop just following the first idea that came to my mind, and it somehow worked, I had veggies. But I guess I could do better with some reading and learning about good practices.

Just yesterday I came across a video on YT that is just brilliant : https://www.youtube.com/watch?v=ETo6sJT_OJE

Looking for more like this. Be it in video, book or blog form.

Thanks!
