Part of what makes Martinelli's vegetables so extraordinary is the permaculture methods he uses to grow them. An agricultural movement begun in Tasmania about 24 years ago, permaculture rejects the typical farming practice of subduing and altering nature in favor of working with the land's ecology. Rather than leveling a hill to make room for a field of carrots, Martinelli plants right on the slopes. He uses ditches to regulate the amount of rainwater running down the incline, slowing soil erosion and protecting the seedlings. Instead of chopping down trees to clear the land, Martinelli plants mizuna under the boughs. The shade prevents the greens from turning bitter. He also cultivates watercress in springs, its prime natural habitat.
Waters appreciates Martinelli's approach: "Pete's vegetables have a life in them that translates to the plate. He understands that vegetables need to be at their best, but he sees the big picture as well and is committed to preserving the natural resources of his farm."
