More than 900 U.S. schools are competing for the chance to win an organic garden or an organic-only vending machine.

Schools compete for organic garden or vending machine

The contest, part of the Greenfield, Mass.-based Organic Trade Association’s “Organic. It’s Worth it in Schools” campaign, runs through May 1, according to an association news release.

Students, teachers, parents and others have until May 1 to vote online for their school.

The school with the most votes will get either a garden complete with seeds, soil and expert gardening support; or a vending machine stocked with organic fruit, milk, cheese, yogurt and other items.

When people vote, at www.OrganicItsWorthIt.org/school-newsletter, they’re put on a mailing list to receive an electronic newsletter devoted to organic food.
