The "Three Sisters"
Companion Planting Method
Companion planting is a gardening technique where certain vegetables are grown together to take full advantage of their natural tendencies and relationships. While there are many different types of companion planting, the three-sisters method has been used for centuries by Native American tribes.
The “three sisters” are a combination of these three plants working together:
“Sister Corn” provides support for beans vines to climb up.
- Plant your favorite sweet corn, dent corn, popcorn, or even a combination.
“Sister Beans” deposit nitrogen from the air into the soil, in a form that the plants can use.
- Plant pole beans such as Blue Lake, Scarlet Runner, or Italian Snap, or any climbing bean. (not bush beans)
- The beans will use the corn as support, so wait to plant the beans until the corn is about knee-high.
“Sister Squash” shades the ground with its large leaves.
- Squash can be winter or summer types, or a combination of both.
- The squash provides shade that chokes out weeds that might compete for resources and keeps the ground moist.
