What once was a garden is now overgrown with weeds. I started a cardboard/mulch smothering project before I realized I had access to a rototiller. I will most likely keep it there. The overall space is 14 yards by 14 yards. I'd like to add raised beds for perennials and a sitting area. I'm hoping for advice on arrangement. I live in MA. The photos of the space are left to right and then straight on.
