@gsuberland@chaos.social To be clear, I use the phrase 'raised beds' but it's a little different from your usual (high-effort, robust, solid) raised beds; because you basically never interact with the soil it doesn't need to be rigid or robust, so sticking a bunch of branches into the ground to create a 'fence' that holds back the soil (maybe with a little metal wire around the whole thing) is pretty much enough to tick the box 🙂
(That may still be too much effort for you, just wanted to make it clear that I don't mean the fancy nice-wood things you usually see as raised beds)
