Gardening in America: Each year, over 121 million Americans visit public gardens. From public green spaces to community gardens to private yards, gardening is a critical part of our country’s culture. Gardening in America offers an introductory overview to the state of the country’s gardening culture, contexts that inform gardening, and ways to apply gardening approaches, styles, and practices for the greater good.  

Ecological Gardening: Over 114 million American households engage in gardening. From public green spaces to community gardens to private yards, gardening is a critical part of our country’s culture. A garden is a living ecosystem that impacts the health of people, plants, animals, and the environment. Ecological Gardening is designed to share ecologically sound gardening methods and practices that promote sustainability in your own gardens that will grow a greener future.
