For lots of Native American communities, three crops have carried out a big place in indigenous agricultural practices – corn, beans, and squash. Typically known as The Three Sisters, these crops show how of us can revenue from working with nature pretty than in opposition to it.
Who’re the Three Sisters?

The Three Sisters are corn, beans, and squash. Significantly, the corn varieties are sometimes flint corn meant for drying and grinding into cornmeal, the beans are sometimes pole beans which may be harvested when completely ripe and dry, and the squashes are pumpkins or completely different winter squashes that develop on a protracted vine.
The ultimate idea is that the corn acts as a pole or trellis for beans to climb, the beans add nutritional vitamins to the soil due to the nitrogen-fixing micro organism of their root nodules, and the massive leaves of the squash crops act as a pure mulch that shades out weeds and retains moisture from escaping.

Totally different crops may be grown alongside the Three Sisters and usually get referred to as a “fourth sister.”
In jap North America, the “fourth sister” is prone to be amaranth or sunflower. Inside the US Southwest, Mexico, and Central America the place corn-beans-squash is the cornerstone of the milpa agricultural system, completely different crops like chili pepper and tomato is prone to be planted as companion crops.
Apart from being tasty and/or nutritious of their very personal correct, these completely different “sisters” may provide benefits to the yard similar to attracting pollinators or repelling pests.
So why are they known as the Three Sisters? Native American custom is actually not singular, with over 500 federally acknowledged tribes throughout the U.S. alone. Truly, not every tribe makes use of Three Sisters planting, and the beliefs and customs surrounding these crops differ.
Contained in the Iroquois and the Cherokee custom, corn, beans, and squash had been known as the Three Sisters because of they nurture each other like family when planted collectively consistent with Christina Gish Hill with the State School of Iowa Three Sisters Problem.
Equally, there is a notion in plenty of Native communities that our kin is not going to be merely the oldsters to whom we’re related by blood or DNA, however as well as embrace the non-human beings who we share our environment with. We rely on them they normally rely on us.
Two-way relationships of reciprocity and care between individuals and non-humans are utterly necessary for everyone to thrive. Calling these crops “sisters” is a reminder that they aren’t merely sources to make the most of, nevertheless that they are part of our internet of relationships linked by accountability, care, and even love.
The Potawatomi botanist Robin Wall Kimmerer goes into bigger aspect about this idea of relationships of reciprocity with our non-human kin in Braiding Sweetgrass.
How the Three Sisters practice us to work with nature
Three sisters gardening is an effective occasion of strategies to work with nature pretty than in opposition to it.
In case you plant corn, beans, and squash in separate rows in a traditional yard, you have obtained a great deal of work ahead of you: it is good so as to add a bunch of fertilizer, spend a great deal of time weeding and presumably spraying pesticides, and it is good to work out a system for staking or trellising the beans.
In a Three Sisters yard, a great deal of that work is taken care of for you by the interactions between the crops. The usual methodology is to assemble a mound of soil, add compost or completely different pure fertilizer if wished, and plant quite a few corn seeds throughout the heart. As quickly because the corn is a few inches tall, the beans are planted surrounding the corn. Squash seeds is likely to be planted after the bean seedlings emerge.
Variations on this technique are moreover potential. Corn is prone to be grown in a row, with beans and squash planted to each aspect. The corn may also be grown in a grid, with beans and squash interspersed.
Three Sisters gardens are onerous to implement on a enterprise scale because of they’ll’t really be planted or harvested with tools. Nonetheless, some home gardeners and pure farmers have had success rising the Three Sisters.
One among many challenges with rising the Three Sisters is figuring out the exact varieties to utilize. As an illustration, the stalks of sweet corn varieties are usually too temporary for the beans, whereas popcorn stalks usually aren’t sturdy enough.
