Tiffany Grenkow has made it her life's mission to feed as many people as she can. Her gardening is focused on creating abundance, and the results are shared throughout her community. Meanwhile, her tenacity in gardening research, leads her beyond current scientific thinking to pioneer a new technique of propegating sweet potatoes. In 1995, Bob Duncan planted the first citrus trees in the ground in Canada. Decades later, he continues to grow hundreds of varieties of oranges, lemons, and other exotic Mediterranean tree fruits. His methods are developed through extensive testing and a simple yet effective technique of overcoming the winter frost.
