I don’t think you necessarily need acres and acres of land to grow a good amount of food. Even if it’s not 100%. You can grow
a lot on even just an acre, or even less, especially if you utilize things like square foot gardening, raised beds, pots, even those vertical growers, etc. it might not be 100% but it will still be a lot.
I think it also depends on how much you eat too because like for example, our family are really not big vegetable eaters. Last year we had a pretty big garden and lots of different vegetables and we really didn’t even eat most of it.
Partially because we don’t eat vegetables much but also just because we had soooo many cause it was producing like crazy.
And like for example, one of the articles says you need like 40 tomato plants (another says 5-8 which seems more accurate) and one says like 10 cucumbers, etc. but we usually always grow at least 10 or 15 tomatoes and end up with waaaaaaaaaayyyyyyyyy more tomatoes than we even know what to do with.
If we had 40, we would be drowning in them and they would never get eaten. Unless maybe we canned or made salsa or pasta sauce or something with them but even then probably still not.
And we only had 3 cucumber plants and had more cucumbers than we know what to do with. And was actually mostly just one plant providing most of them.
So I think a lot depends on how much you eat and also how productive your garden is. Ours was on the old chicken run plus composted some so very fertile and produced tons. If your plants or soil or whatever isn’t very productive then maybe you’d need more or maybe good to plant extra anyway in case some get diseased but even then I don’t think you necessarily need a ton of room.
And year the garden is even bigger and we’re growing even more vegetables than last year, lots of new kinds. And we’re actually making a second garden to be able to fit it all haha growing a lot in containers too.
I thought these articles were interesting. They give lots of number and footage and stuff for various plants. The first one seems more reasonable to me but it all depends. I guess if you ate a lot, the second one would be more necessary. I should also note we only have 3 people here (though do sometimes give some to DB) and if you were providing for an individual you’d probably need even less space. I also think that even if it’s just for the summer and you have to buy in winter, that’s still pretty good.
