Traditionally, the Iroquois were a mix of farmers, fishers, gatherers and hunters, although most of their food came from farming. The main crops they farmed were corn, beans and squash, which were called the three sisters and were considered special gifts from the Creator. These crops are grown strategically. The food was stored during the winter, and it lasted for two to three years. When the soil eventually became less fertile, the Iroquois moved.
