Keyhole Raised Beds
Interesting shape for a raised bed.
"Anybody who’s ever grown vegetables in a raised bed garden knows how awesome they are at producing an incredible yield that eclipses that of a traditional garden. But no matter how productive your design has been, chances are that it’s not as productive as the one I’m about to share with you. What’s it called? A keyhole garden. Intrigued? Read on.
A keyhole garden is round, roughly six feet across and has waist-high walls. The name comes from the distinctive shape of the garden, which has a round column in the center and a slot jutting out on one side, making it resemble a keyhole. As much as I’d love to say I came up with this method of raised-bed gardening, it is believed to have originated in areas of Africa in which communities had very poor soil and a long dry season and, as such, were seeking a means of growing fresh veggies as economically as they could."
I like how its waist high, good for someone like me that's older and has trouble bending. I'm guessing that the wire cylinder in the center is a composting pile.
The circular design does waste some floor space but there are square designs too. Might be a way to camouflage your composting piles in a urban setting too, where neighbors might gripe about any imagined smells.
