My friend LOVES her keyhole gardens. She has them everywhere
She has them in quite a few shops too. I don’t think she
puts her wigglers in those, though. Right now she’s planted, I think 16 different vegetables in 2 of her gardens. We’ve seen pictures of keyhole gardens made of stone, bricks, curved aluminum, wood. Our Community Garden was once a Wagon Repair shop, then a farm with horses & cows, chickens, you name it. We’ve found parts of wheels, all sorts of metal parts for something or other, chards of plates, bowls, pieces of kitchen sinks, tiny, tiny bottles, bricks, pieces of bricks, and other stuff. We’re going to make a keyhole garden from some of this stuff, plus pieces of found broken concrete, and arrange is “artistically” hubby says “if it can be artistically arranged. I’ve even found quite a few old marbles. I still have some marbles I had as a child, so I know old marbles, even my steeley.
