When Margaret Park moved from rural North Carolina to downtown Salt Lake City, she needed to come up with new methods of vegetable gardening in her small urban backyard. Over four years, she experimented with tighter seed spacing, vertical growing supports, multiple cropping through the year and composting with EM bokashi to arrive at a highly productive system to grow a lot of food in a small space. Margaret Park is the author of four children's books. She was a 2012 Grow America finalist.
