The average age of gardeners in America is about 45 years old; they usually fall somewhere in the middle class. But the fastest growing groups are city dwellers. Urban residents are finding ways of gardening even in their crowded areas. Many go to large public gardeners, as a place designed by the city for garden, and you can actually ranch your own plot.
