Companion planting has become more popular in recent years because it helps to maximize available garden space and provides a sustainable environment for better crop production.
The truth is companion planting methods have been around for a very long time. In fact, the Native Americans might be some of the earliest known gardeners to use companion planting.
They used a planting technique called “The Three Sisters Method“.
Companion planting with the Three Sisters Method is a wise way of using available garden space and maximize yields.
What Is the Three Sisters Method?
Each vegetable is interplanted together so they benefit one another while growing and producing fruit.
The corn stalk provides a climbing support for the pole beans to grow up, the pole beans provide nitrogen in the soil for the corn, and the squash creates a living mulch to block out weeds and to conserve soil moisture for the pole beans and corn.
They are known as the “sisters”. A trio that works in complete harmony.
How to Plant a Three Sister Garden
For best results using the Three Sisters Garden, you will need an area that receives full sun and large enough to create a mound of soil that is about four square feet.
Mound up the soil about one foot high and two feet wide.
Flatten the top of the mound to create a level planting surface. You can also use a raised bed for the Three Sisters method if you have poor soil or drainage.
If you plan to create more than one make sure they are at least four to six feet apart.
In the center of the mound, plant the corn in a circle with the seeds spaced about six to seven inches apart. Water the seeds well after planting and continue to water each day until the seeds have sprouted in a couple weeks.
Once the corn has reached a height of ten to twelve inches sow the pole bean seeds in a circle six inches outside of the corn stalks.
The pole beans should sprout in seven to fourteen days. Remember to keep the mound well watered during this time.
A week after the pole beans have sprouted it is time to sow the squash seeds. Sow six squash seeds in a circle that is about twelve to fifteen inches away from the pole beans. Keep the entire mound watered well and the squash should pop up in about a week.
Make sure to train the pole beans to begin climbing up the corn stalks. You may need to begin wrapping the pole bean vines around the corn stalks to get them going in the right direction.
In just a few weeks the squash leaves will begin spreading out, shading the area and keeping the soil cool and moist.
