I had heard about the Three Sisters Garden practice, but didn’t know much about it until I recently found these seeds from Renee’s Garden, at Callahans. The packet contains equal parts Earth-Tones Dent Corn, Rattlesnake Beans, and Sugar Pie Pumpkins. This is what it says:
“According to Iroquois legend, corn, beans, and squash/pumpkins are inseparable sisters; precious gifts from the Great Spirit. The tradition of interplanting them in the same mounds is actually a sophisticated, sustainable system providing long-term soil fertility and healthy harvests.” You plant the corn first, which provides natural poles for the beans to climb. You then plant the pumpkins which cover the ground and act as mulch, and shade out the weeds.
I don’t currently have room for this, because you need three 10 foot rows, each 5 feet apart. But I’d like to plant a Three Sisters Garden at some point.
