Recently I saw a small farm post about how they're growing things upside-down from hanging gardens to save space and I have to admit, it's lovely. It makes a gorgeous focal point and I think it would be gorgeous to walk through, take photos and just see all that loveliness from a new perspective. I grow my strawberries this way and they are beautiful.
That said, some of the items they have hanging include pumpkins, which gives me pause. I grow pumpkins and they can get pretty heavy. Even if you're only growing little sugar pumpkins for pie making they can still fall off the fine and knock someone in the head. Where I live, that could be a person, a chicken, a dog... So yeah, I don't think I'd feel comfortable growing pumpkins this way, but it does make sense and if you're super careful and not worried about unsuspecting people or animals under it, maybe it would work fine.
What other freaky, strange or just different types of gardens have you seen? Share them in the chat.
