Here's a reason not to cart those vegetable peelings to the curb:
Woman Discovers Lost Wedding Ring Growing on Carrot
A woman in Sweden found her wedding ring, sixteen years after losing it in the kitchen, growing on a carrot in her garden. She thinks the ring accidentally went out to the compost pile all those years ago, and made its way into the soil.
(I lost a small diamond out of my engagement ring in the garden a number of years back, and unfortunately it has never turned up in my harvest; I don't wear the ring while gardening any longer. Spoons quite often seem to turn up in my compost pile; jewelry, never. Oh well.)
