I’m quoting here from an email promoting the Kitchen Gardeners International newsletter: “One part Victory Garden, one part American Idol, the Grow-Off Show-Off pits gardeners against one another in a friendly, light-hearted creativity competition to see who can come up the cleverest and most effective ways of singing the praises of home-grown foods.”
Billed as “no holds barred.” Isn’t there a gardening or growing metaphor that would work there?

Friendly or “no holds barred,” it’s got to be interesting: an organic gardening competition.
