Imagine a small garden that produces an above-average harvest, yet needs minimal water, fertilizer, and weeding—and, as a bonus, leaves your soil more fertile at the end of the growing season. Some might call that a dream come true, but what it’s really called is a Three Sisters Garden.
Yet this remarkably savvy strategy for growing corn, beans, and squash wasn’t developed by a Ph.D. in a modern research garden. Instead, it began centuries—perhaps millennia—ago as a Native American agricultural tradition.
What is a Three Sisters Garden?
Unlike today’s gardens where plant varieties are separated by straight rows, a Three Sisters Garden allows corn, bean, and squash plants to grow together and benefit from each other.
The beauty of a Three Sisters Garden comes from the symbiotic relationship between these three crops.
