Case In Point The Three Sisters When European settlers arrived in America in the early 1600s the Iroquois had been planting three sisters gardens for more than 300 years The Iroquois discovered important practical reasons for growing corn beans and winter squash together The tall corn plants serve as poles for bean plants to climb Bean roots add nitrogen to the soil fertilizing the corn Squash mulches or covers and protects the soil around the corn and bean plants Although mulches are often dead organic materials such as decaying leaves or straw the huge leaves of living squash work well too They provide insulation meaning water is retained sun does not bake the soil and weeds cannot grow At the end of the season the dead squash plants can be left in place to add nutrients to the soil In these ways the three plants thrive together improve the soil and make the gardener’s work much easier When grown together the plants require less weeding and watering Letting the beans grow upward means there is no need to bend to pick them There is less need to fertilize because the bean plants and remains of all plants add nutrients and organic matter to the soil Together the three sisters make a nearly complete human diet beans provide protein corn provides carbohydrates squash provides vitamins and squash seeds and corn provide oil Before the Industrial Revolution most European Americans were farmers Farms in the 1800s were small producing small amounts of many crops Farm families planted gardens and raised chickens cattle and hogs some of which they butchered for meat Except for flour salt and sugar farmers grew all the food they needed to feed their families 8
