In progress: these aren’t exactly "raised" yet, but we’re moving in that direction.

Question by Stuck in the Middle Ages: Any ideas on how to create a raised vegetable garden bed on a slanted backyard?
We’d like to have a raised bed, but there’s a slant to the yard that would require one side be higher than another. I’d like to simply use a kit, but I’m not sure if that’s really feasible with the slant.

Thanks.
