How does chinampa gardening work?

Chinampa gardening is an ancient agricultural technique originating from the Aztecs, involving the creation of floating gardens on shallow lake beds. Farmers build rectangular plots, or chinampas, by layering mud, reeds, and decaying vegetation, which creates fertile soil above water. This method allows for year-round cultivation, as the water helps to maintain moisture and nutrients. Additionally, the canals between chinampas facilitate irrigation and transport, enhancing productivity.
