Wondering how many people here like growing shit. it's great, been doing it for a couple years now. Started with a few outdoor weed plants sometime after CA got legal and i just kept potting more and more stuff. Herbs are so easy, so long as you water them often and know how much sun they need. We had a big heatwave here last year and I moved a few inside but the bigger crop got annihilated, like burnt to crisp bad. Going to keep those ones near a fan inside this summer. I dig it more than I thought I would though. I got some tomatoes, green onions, a few hot peppers, random herbs, and a small lemon tree now. All super easy to take care of, highly recommend it.
yeah my grandma has a small tangerine plant too and it's only like maybe 2x2x5feet maybe half a foot wider each at most, and it yields a few dozen of them! you can do it in smaller spaces. They require a bit more love than lemon i think though, but they are awesome. Just get the right soil cause citrus does need a richer soil and they also need a lot more water than a lot of plants to fruit well.
IDK offhand if kaffir limes can be grown like that or if they'd enjoy the climate, but that'd be a neat plant to have around. Something I can't just get at the grocery, plus it has those crazy leaves
