The Three Sisters method is an Indigenous companion-planting technique that's been used for thousands of years across North America. The method combines corn, beans, and squash to work together in ways that naturally support each other and reduce pests and weed issues. More and more gardeners have been looking for natural ways to replace pesticides and other chemicals. 

The scoop

One gardener, Wonderfully Ordinary (@wonderfullyordinarygardening), took to TikTok to share a video on how she set up a Three Sisters complex in her own backyard, starting by laying out cardboard boxes and mounds (and doing it in less than an hour). The long-used gardening method is low-cost and taps into ancient wisdom that continues to benefit us in the modern world. 

@wonderfullyordinary Here's how I set up a three sisters style garden. The three sisters garden is a Native American garden design that interplants corn, squash and pole beans. There are many different design options for planting, but I chose the one that I had the space and materials to setup. Here is a step by step of how I built this bed. #gardening101 #gardening #threesisters #vegetablegardening #gardensetup #corn #squash #planttok #tiktoklearningcampaign ♬ original sound - wonderfullyordinarygardening

According to the video's caption, there are "many different design options," but she chose a design that suited her space and materials. 

The gardener measured out a 10-by-10-foot area and laid down cardboard as a weed barrier before covering it in wood chips. She built 18-inch-wide mounds 4 inches deep, filled with a mix of soil and cow manure, arranged five mounds across, and then two more rows. 

They planted four corn kernels 6 inches across from each other in a diamond within each mound and three squash per pound, planning to "thin it down" to two squash per mound. The gardener planned to plant pole beans next, using the corn stalks as natural support and finishing with a garden that alternates corn and squash, just as the traditional Three Sisters technique. 

How it's helping

In practical terms, the Three Sisters technique saves both time and money since you don't need trellises or plastic mulch, and the plants protect each other naturally. 

Scientific sources note that implementing these three crops helps suppress weeds and pests as squash suppresses weeds, beans nourish the soil with nitrogen, and corn gives climbing support to the beans, according to Garden Insider.  

The method helps gardeners cut down on synthetic gardening tools and methods, which is better for not just the plant but also helps save on gardening costs. Plus, growing your own food or vegetables reduces reliance on mass-produced produce that is globally shipped and helps lower that environmental footprint. 

Research also shows that gardening provides an array of health benefits, like supporting a higher fiber intake, lowering stress levels, and improving mental health.
