In the foreground is her tomato patch. She raised it a bit, just by adding old boards around the edge and back filling with some soil. As the boards wear out, she replaces them with new/old boards. Then she has her tomato supports - some great branches that she found in the woods. I think these are the same ones as last year, but as they break down she just gets some new ones. Simple as that. And she places flat rocks here and there in the raised bed so she has somewhere to rest her foot when she needs to lean in to weed.
In the background is the main vegetable bed. Instead of leaving the paths between each row to dirt and weeds, again she uses old boards that would otherwise be thrown away. They add order to the bed, repeat the wood "theme," and are easily movable when she lays it out for next year.
I have major garden envy. I really need to keep just this photo as my inspiration for next year.
