In order to maximize energy and space in the garden, many gardeners choose to co-plant multiple crops together in the same field. In the Beach flats garden, corn beans and squash are planted together in various formations according to each gardener’s experience and traditions. Corn beans and squash co-planting is known as a three sister garden and is common in many indigenous planting traditions. There are two ways in which corn and beans are commonly co-planted in the Beach Flats Garden. The more common method involves planting the corn 1 to 2 months ahead of the beans, so the corn has time to grow. This method produces a larger yield from the corn in exchange for a smaller quantity of beans. The other method involves planting them at the same time and allowing the beans to climb over the corn as it grows. The bean yield is greater while the corn is reduced. As the beans grow they feed the soil to the benefit of the corn beans and squash in the parcel. The third sister, squash, can be seen growing in the rows. The squash plants reduce evaporation and weed growth by making shade in the parcel. Vine squash can be trained to grow down the rows to maximize the effect. However a gardener chooses to plant, if the garden has corn beans and squash, its a happy garden.
