I've always been very curious about people in the garden who have tried the three sisters method for planting corn, beans and squash in the space space. I decided to do a little research to learn how to do it.
On the webiste, Runee's garden, she says, "According to Iroquois legend, corn, beans, and squash are three inseparable sisters who only grow and thrive together. This tradition of interplanting corn, beans and squash in the same mounds, widespread among Native American farming societies, is a sophisticated, sustainable system that provided long-term soil fertility and a healthy diet to generations. Growing a Three Sisters garden is a wonderful way to feel more connected to the history of this land, regardless of our ancestry." (http://www.reneesgarden.com/articles/3sisters.html)
Most websites advise to plant the corn seeds once we've finished having frost at night. Once the corn has grown several inches (advice seems to go from 4 to 8 inches), the plant the bean and squash seeds around the corn plants. As the corn grows, the squash and beans will grow around it.
Would love to hear comments from any one in the garden who has tried this--were you successful or not? How does it work in an urban setting like 6/15 green?
