How To Plant A Three Sisters Garden

Last Updated: September 11, 2022

Did you know that corn, beans, and squash are called the “three sisters”?

A number of Native American tribes interplanted this trio because they thrive together, much like three inseparable sisters.

Here’s how to plant a three sisters garden.

The Three Sisters Garden

By the time European settlers arrived in America in the early 1600s, the Iroquois had been growing the “three sisters” for over three centuries.

The vegetable trio sustained the Native Americans both physically and spiritually. In legend, the plants were a gift from the gods, always to be grown together, eaten together, and celebrated together.

Each of the sisters contributes something to the planting.

Together, the sisters provide a balanced diet from a single planting.

  • As older sisters often do, the corn offers the beans needed support.
  • The beans, the giving sister, pull nitrogen from the air and bring it to the soil for the benefit of all three.
  • As the beans grow through the tangle of squash vines and wind their way up the cornstalks into the sunlight, they hold the sisters close together.
  • The large leaves of the sprawling squash protect the threesome by creating living mulch that shades the soil, keeping it cool and moist and preventing weeds.
  • The prickly squash leaves also keep away raccoons and other pests, which don’t like to step on them.

Together, the three sisters provide both sustainable soil fertility as well as a heathly diet. Perfection!

How to Plant the Three Sisters

Before you Plant

Three Sisters Garden

  1. Conduct a soil test, and prepare the garden site.
  2. Add compost or other materials such as peat moss or manure to the soil. This will improve the soil structure and add nutrients.
  3. If you have grown a green manure cover crop such as winter rye, turn it under two to three weeks before planting.


  1. Plant corn in late May. It is best if the ground has warmed and is no longer cold and wet. Iroquois tradition holds that planting begins when the leaves of a dogwood are the size of a squirrel’s ear.
  2. Soak corn seeds for several hours, but not more than eight hours, before planting. (Soaked seed may dry out quickly, so keep the seeds well watered for the first week or two if the soil is not kept moist by rain showers.)
  3. Prepare low hills that are 3 to 4 feet apart within and between the rows.
  4. Place five to seven corn seeds, evenly spaced to a depth of I to I ‘/2 inches.
  5. Cover with soil.

There are many corn varieties to choose from.

Dent, flint, and flour corns are especially suited to this system, while popcorn often does not get tall enough and may be overwhelmed by the beans and pumpkins. If you care to follow Iroquois custom, plant the seeds with kind thoughts three days before the full moon.


  • After young corn plants come up, begin removing weeds.
  • As you are weeding, gently mound, or hill, the soil around the young plants.
  • When the corn plants are about 6 inches high, pole beans and pumpkins can be planted around the corn plants. Genuine Cornfield or Scarlet Runner bean and Connecticut Field or Small Sugar pumpkins are heirloom, non-hybrid varieties that are readily available, yet “authentic” crops for your project.

After thoroughly weeding, plant four or five bean seeds in each hill.

  • Plant four or five pumpkin seeds in every seventh hill, placing them around the young corn plants. (Planting pumpkins in every hill would quickly overwhelm your site with viney growth)

Your plants will need water each week. If it does not rain at least an inch per week, the planting will need to be irrigated. If you are using presoaked seed, remember to water more frequently at first.

Most of the nitrogen converted by the beans will nor be available to the corn and pumpkins the first year; the bean roots have to break down to release nitrogen.

Corn is a heavy nitrogen feeder, so sidedressing with fertilizer is necessary to achieve satisfactory yields. You can use manure. compost, or commercial fertilizer.


If you are hoping to keep a variety pure–for example, an heirloom variety of corn you will need to isolate the corn from other varieties. If isolation is not possible, you need to hand pollinate.

This is a challenge, but it is fun to experiment to see what results you can get.

To hand pollinate, place waxed paper lunch bags over the newly forming silks to keep out unwanted pollen.

When the plants are tasseled 2 inches out, remove the bags briefly and shake the desired pollen on the silks, then replace the bags. Your desired pollen may be that of the same variety.

If you are experimenting with crosses, however, the pollen must come from another variety. You can use brown paper lunch bags to collect pollen from the tassels of the desired variety. Be sure to keep track of which plants you have hand pollinated so you can compare them with those that have cross-pollinated.

Harvesting & Storage

Harvest and store your corn, beans. and pumpkins with care.

When the corn husks are dry, pick the ears and spread them out in a dry place.

To prevent mold, do not store the ears when they are first harvested.

If you plan to grind the corn. let it dry for several weeks.

If you plan to save seed, choose seed from your most vigorous, uniform plants from the center of the ear.

After you have shelled the kernels, keep them in a cool, dry place in covered containers or plastic bag. Following Iroquois tradition, do not let a single kernel go to waste!

You can harvest your beans when they are green or after the pods have shriveled and dried. Pick pumpkins when their color changes.


  • Try cooking a new food from the corn, such as hominy or succotash.
  • Save the husks to make baskets or dolls.
  • Weave a basket; create a corn mosaic. ​
  • Use the plants to decorate your mailbox, a flagpole, or a tree trunk.
  • Compost the remaining plant material.

At the end of the season, have a harvest festival, Celebrate Thanksgiving with the fruits of your labor and appreciate your rich American heritage.
