Assume you had access to a 6 by 6 balcony that faces south with a nice railing and (miraculously) endless access to water. Set whatever budget makes it interesting for you. How would you design your garden to produce as much food as possible? Could you produce enough to sustain yourself? How close could you get? What crops would you prioritize?
the book on Square Foot Gardening was what got me into balcony gardening weirdly enough!! Someone thought it’d be a great book to gift a ten year old (me) and I was obsessed with it growing up (so they were correct). Now I’m in an apartment and I’ve been thinking about that book a lot. I didn’t even think about applying it to the balcony, though
