My favourite quote recently is from the host of Gardening Australia. Yeah, I’m watching a few more housey programs since we got back. Anyway, this guy, Peter Cundall, is in his late seventies, and a bit of a comedian as TV gardeners go. He said: “If you cut a worm in two with a shovel, you don’t get two worms, you get one dead one. And they don’t forgive you.”
So use a garden fork, and don’t risk the wrath of the worms.
