Gardening in America

Believe or not, 43,000,000 Americans are gardening. That is about one in six. Gardeners, of course, come in many varieties. Not surprisingly, most of them are people who live in the suburbs, and enjoy planting flowers, or maybe a small vegetables garden.
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 gardens, as a place designed by the city for garden, and you can actually ranch your own plot.
Still other people use their balconies or roof tops, wherever they can find the space to plant small patches of green.
