In an incredibly ironic twist, a suburban home garden is now a sign of wealth too. Having a sunny space large enough to grow food, and even more importantly, having the time to tend to it.
I'm from South America, and my grandma's house had: mango, peach, lime, orange, grapevine, berries, coconut, jaboticaba, pitanga, acerola, atemoia (native fruits), and many types of spices (including a bay laurel tree). All that in a lot that barely parked 3 cars.
Once setup it's low daily maintainance, pull weeds when seen and throw them in the compost, lots of things self seed or come back when leftovers + compost are turned over in a clean bed.
The layout dates back to the 1930s and was planned to be self sufficient with no "grid" as such.
Now it's much as it was with solar panels, big batteries, and fibre + home lab.
We have two three sided "bunkers" 2 metre x 2 metre square x 1.5 metre high that we fill with weeds and then cover every spring (on rotation), once covered they cook pretty hot which kills most things within, reduce them to juice and worm food and when respread a year later they grow good veggies.
We've just today finished spreading three double axle trailer loads (each about 1.5 tonne) of donkey poo and straw .. that's got a lot grass seed and digested grassy fecal matter in it .. it'll make great figs and probably grow grassy weeds under the fig tree .. that'll get pulled and thrown in the heaps also.
Pretty much the only things that don't go in the compost piles are metal, rocks, plastic, etc - if it's organic, it's in.
