In hindsight , I should ’ve train a picture of my Three Sisters garden when it was just getting started ; I simply had n’t considered how tight it would grow ! The image above was only a week old at the time I wrote this article , yet those squash vine had already grown several more feet and the Indian corn stalks had formed silks and tassels .
And just a couple of weeks after that , I was able-bodied to harvest from that once - overleap 4×6 bed that had been revive over winter through theno - excavation horticulture method . ( Proof that you do n’t need to buy bagful of expensive soil to begin constitute ; you could make your own ! )
But I ’m getting forward of myself here . If you ’ve never hear of a Three Sisters garden , you might be wondering what this vast cluster of planting is all about , and why it ’s holler the Three Sisters .
Who are the Three Sisters?
root in Native American history , the Three Sisters garden is the original basis for companion planting , a useful technique in gardening where sure vegetables are farm together to take vantage of their natural tendencies and relationship — a descriptor of reciprocal tending companionship , if you will .
The Three Sisters were the main agricultural crops that sustain the Haudenosaunee ( also have sex as the Iroquois ) for centuries before European colonist ever arrived : maize ( corn ) , dome , and squash .
This ancient method of closely interplanting three companion crops created a sustainable ecosystem , in which the corn grew tall to provide the noodle a anatomical structure to climb , the beans stabilized the Zea mays stalks andfixed nitrogen in the soilfor heavily - alimentation squash , and the squash vine sprawled across the bed to shade the dirt and suppress the weed ( in effect , acting as an comestible reason cover ) .
The Iroquois believed that the Three Sisters could only mature and flourish together in community , as they complement each other not just agriculturally , but nutritionally as well . Corn was a reservoir of saccharide , beans were deep in protein , and squash provide vitamins and mineral — a well - rounded diet to supplement the hunter / accumulator life . These three crops could also be dried and used as food twelvemonth - pear-shaped .
While these trait are less important today , they were so important in the past that they became the major cultivated crops of Indigenous peoples . In our current world of monocropping and overworking the soil , we can still learn a lot from this arrangement to practice companion planting and ameliorate grease fertility .

Varieties to plant
The Three Sisters method acting entails the keep abreast fellow plants operate together :
Corn
This should be a tall potpourri to give the bean plenty of room to go up ( and to ensure the beans do n’t overcrowd the corn ) . Some former varieties are shorter plants that mature apace , so they wo n’t work for a Three Sisters garden . Go with your favorite sweet corn , dent maize , or even popcorn here .

Beans
Beans should be a climbing character ( also called pole noggin ) and not bush types , which stay compact and do n’t need support . Lima , runner , yardlong , and common bean form well , as you want non - vigorous crampoon and bushy pole types that wo n’t take over the clavus .

prompt crest : Before you plant beans , you shouldinoculate the soil with rhizobiato maximize the amount of N the attic can determine .
Squash
Squash can be summer or wintertime types , or a combining of both . But pay attention to what you plant : Some summer squash , like zucchini , are bush types that stay relatively small and erect . These work great in a raised bed or other compact infinite , but in general , you want the vines on your squash vine plants to circularise at least a few feet to properly“mulch ” the soil .
On the snotty-nosed side , be cognisant that smartly vining winter mash likePink Bananacan acquire up to 15 feet recollective , so it can rapidly overwhelm the other two Sisters if you have a minor garden . I typically look for squash vine varieties with vine between 4 to 8 foot long .

Quick steer : Because of their interchangeable growth drug abuse , other cucurbit ( like melons and gourd ) can be substituted for the squash racquets . Consider growing these crop in position of or in increase to the Three Sisters depend on what you wish to eat and revel grow .
The other sisters
While corn whisky , beans , and squash are the principal crops in a Three Sisters garden , sunflowers and amaranth were also authoritative to the aboriginal American the great unwashed . They can offer a little shade to the other Sisters in the heat of the good afternoon , ply more stalks to climb , and pull more pollinators with their heyday .
you’re able to add these fourth ( and fifth ) babe to your garden bed as complementary plants and increase the biodiversity of your thousand ( which , in tour , reduces plague and diseases in other plants ) .
When to plant the Three Sisters
Corn , beans , and squash are strong - time of year plant and wo n’t tolerate frost . ( Check yourfirst and last frost dateshere to verify you plant at the appropriate clock time for your climate . ) You ’ll want to get germ in the earth once nighttime temperatures are consistently 55 ° F and above , but not after June 1 .
The plant will also need an area that fetch at least six hour of direct sun each 24-hour interval . ( More is better for sun - sleep with squash . )
In areas with very red-hot , dry summers , like the American Southwest , it ’s of import toplant the cornso that the pollen loose during the corn whisky ’s tasseling point ( anywhere from 30 to 70 days after planting , depending on the variety ) happens before the time of year hits peak temperature ( typically in other July ) . High heat or depleted humidity during tasseling can lead to the pollen being sterile or much less effective , which then leads to ears of corn with missing kernels .
It ’s in force to mastermind sow seeds in the garden , since all these plant ( edible corn , edible bean , and squash ) do n’t graft well . That said , youcantransplant seedlings if you have a short growing season ; just attempt not to vex their roots too much , since transplant daze can set them back a bit .
So, in what order should you plant?
constitute the Three Sisters in the monastic order of1 ) corn , 2 ) bean , and 3 ) squashwill ensure they grow and mature together ( and not grow at the expense of another sister harvest ) .
By plant the corn first , it has a fortune to develop nice and improbable above the other crops .
Bean ejaculate should be sow two to three weeks later once the corn is a few in tall — this ensure the Indian corn stalks are tall and sturdy enough by the clip the bean send out tendril and want to go up .
Sow squash seeds two weeks after the edible bean have evolve ; this render the beans and clavus clip to develop heavy so they ’re not out - vie by the squash .
How to plant a Three Sisters garden
There are many different ways to institute a Three Sisters garden , whether you have flaxen grunge or hard clay , have a slew of soil or are restricted to a raised layer . That said , the principal thoughtfulness will be the amount of outer space you have . You desire to give each single flora enough elbow room to grow , yet maturate enough plant to facilitate pollination .
Corn is pollinated by wind and tolerate a better prospect of bring out nice , full auricle of clavus the more corn whiskey plants you have . It ’s substantially grown in clusters , blocks , or stagger rows ( rather than a single straight run-in ) to ensure enough pollen stick around to all the plants .
Squash is pollinated by insects , so growing multiple crush plants in proximity will draw more insect activity once they start bloom . ( In a apprehension , you could alsohand - pollinate squash vine if pollinator are scarce . )
Beans are ego - cross-pollinate and will produce beans even with just one plant , but in an intensively implant garden bottom like a Three Sisters , they tend to have a slightly blue yield so you ’ll get more beans the more plants you have .
you may found the Three Sisters in a analog or circular formation , count on your space .
My 4×6 seam in these images model against a wall , so I sowed the corn across the back first , place a seed in a staggered run-in every 8 inches . Once the maize seedlings grew 4 to 6 inches improbable , I sow the beans about 6 column inch in front of them , placing a seed every 3 to 4 inches , and then the squash racquets along the edge of the bed every 2 feet , letting the vines eventually spill over the side .

The bean started climb the corn stalk as presently as they were grandiloquent enough , but the vine and tendrils can be trained by hand to latch on in the beginning . They ’ll chop-chop spin around the stalks as they climb higher , a natural tendency that helps keep the top - heavy stalks from blowing over in the wind .
For gardeners with arenaceous soil , it ’s good to grow the Three Sisters in a slight well , as oppose to a Benny Hill in the traditional method . A well will prevent piddle from tend off too quick .
For strong cadaver , a hill ( basically a heap of grime that sit 4 to 6 inches high ) will amend drainage .
If you ’re planting in a raised bottom , just verify your soil is well improve and well draining — you do n’t need to mound the soil since it ’s already mounded ( it ’s just smother by walls ) .
Sample garden layouts
Here are a few more prompting for planting your Three Sisters garden . There is no single “ correct ” way to do it , as long as the clavus provides accompaniment for the beans and the squash spreads across the dirt to assist keep moisture .
Use your creativity and see what work with the quad you have . If you commence your Three Sisters now , you ’ll have Zea mays that ’s “ knee high by the Fourth of July , ” as the saying goes !
