The Three Sisters is a traditional companion planting technique developed by Native Americans. It involves planting three crops—sweet corn, runner beans, and squash (usually pumpkin or squash varieties)—together in a symbiotic relationship that benefits each plant.
The sweet corn serves as a natural support for the runner beans to climb. The beans, in turn, help the corn by fixing nitrogen from the air and enriching the soil with this essential nutrient. Nitrogen is vital for plant growth and is often a limiting factor in crop production. The beans' ability to fix nitrogen benefits not only themselves but also the corn, which requires nitrogen for healthy growth.
The third sister, the pumpkin or squash, is planted between the corn and beans. Its trailing vines spread across the ground, acting as a natural mulch. The large leaves of the squash plants shade the soil, suppressing the growth of weeds and reducing moisture evaporation from the soil surface. This shading helps maintain soil moisture, benefiting both the corn and beans by reducing water stress.

Additionally, the sprawling nature of the squash plants creates a living ground cover that helps to smother competing weeds, reducing competition for resources such as light, water, and nutrients. The dense foliage of the squash also helps to prevent soil erosion by protecting the soil from heavy rains.
The combination of the Three Sisters provides a sustainable and mutually beneficial planting system. The corn provides a support structure, the beans enrich the soil with nitrogen, and the squash suppresses weeds and conserves moisture. This approach exemplifies the principles of companion planting and demonstrates how different plants can work together to enhance overall productivity and create a balanced ecosystem in the garden.
In Nigeria, a variation of the Three Sisters planting technique can be practiced using crops that are well-suited to the local climate and conditions. Here are some examples of crops that can be grown as the Three Sisters in Nigeria:
Corn (Maize): Corn is a staple crop in Nigeria and can serve as the main sister in the Three Sisters planting. Varieties such as the Oba Super 2, DMR-LSRW, or Suwan-1 are popular choices.

Beans (Cowpeas): Beans are commonly grown in Nigeria, and cowpeas specifically are well-suited for the Three Sisters planting. Varieties like the IT84S-2246, Sampea 11, or Ife Brown are suitable options.
Pumpkin or Squash: Several varieties of pumpkin and squash can be grown in Nigeria, providing the trailing and ground-covering sister in the trio. Some common varieties include, Ugu Pumpkin, and Butternut squash.
By planting these crops together, you can harness the benefits of the Three Sisters planting system, including nitrogen fixation, weed suppression, and moisture conservation. It's important to consider the specific local conditions and select crop varieties that are adapted to the region for optimal growth and productivity.

Soil preparation is essential for the successful cultivation of the Three Sisters crops. Here are some steps to prepare the soil for the Three Sisters planting in Nigeria:
Clear the area: Start by clearing the planting area of any existing vegetation, weeds, and debris. Remove rocks, sticks, and other obstacles that may hinder plant growth.
Soil testing: Conduct a soil test to assess the soil's nutrient content and pH level. This will help you determine if any amendments are needed to optimize the soil conditions for the crops. Contact your local agricultural extension service or a soil testing laboratory for assistance.

Soil amendment: Based on the soil test results, you may need to amend the soil with organic matter and fertilizers. Adding compost, well-rotted manure, or other organic materials can improve soil fertility and structure. Additionally, adding a balanced organic fertilizer can provide essential nutrients for plant growth.
Tilling and leveling: Use a garden tiller or a hand tool to till the soil thoroughly. Break up any clumps and remove large rocks or debris. Level the soil surface to create a smooth planting bed.
Mound formation: For the Three Sisters planting, create mounds or raised rows to provide proper drainage and aeration for the crops. Form the mounds by pushing soil together in rows or circular shapes, leaving space between the mounds for planting.

Mulching: Apply a layer of organic mulch, such as straw or dried leaves, around the mounds. Mulching helps suppress weed growth, retain moisture, and regulate soil temperature.
Irrigation: Ensure that the planting area has access to adequate water. Depending on the specific rainfall patterns and irrigation infrastructure available, plan for regular watering to keep the soil moist but not waterlogged.
The timing and method of planting the Three Sisters crops may vary depending on the specific climate and growing conditions in Nigeria. However, here are general guidelines for planting the Three Sisters:
Timing: The Three Sisters crops are typically planted during the warm season when the soil has warmed up and there is no longer a risk of frost. In Nigeria, this is usually in the early to mid-rainy season or when temperatures are consistently above 18°C (64°F).

Corn (Maize): Start by planting the corn seeds. Create small hills or mounds of soil spaced about 1.2 to 1.5 meters (4 to 5 feet) apart. Plant 2 to 3 corn seeds per mound at a depth of about 2.5 to 5 centimeters (1 to 2 inches). Space the mounds in rows with adequate distance between them to allow for bean and squash planting.
Beans (Runner Beans): About a week or two after planting the corn, sow the bean seeds around the base of the corn plants. Plant 3 to 4 bean seeds per corn mound, spacing them evenly. Push the bean seeds about 2.5 centimeters (1 inch) into the soil.
Squash (Pumpkin or Squash): After the corn and beans have sprouted and are a few inches tall, plant the squash or pumpkin seeds. Create small mounds of soil spaced between the corn and bean mounds, leaving enough room for the trailing vines to spread. Plant 2 to 3 squash or pumpkin seeds per mound, about 2.5 centimeters (1 inch) deep.
Support for beans: As the corn grows taller, the bean plants will start to climb the corn stalks. You can gently guide the bean vines toward the corn stalks to help them climb. Avoid damaging the corn plants while doing so.
Mulching and maintenance: Apply a layer of organic mulch around the plants to help conserve moisture and suppress weed growth. Keep the planting area well-watered, especially during dry periods. Regularly monitor for pests and diseases and take appropriate measures to manage them.
The three sisters—corn, beans, and squash—can be affected by various pests and diseases. Here are some common pests and diseases that may impact the three sisters and management strategies:

Corn:
Common pests: Corn earworm, armyworm, corn borer.
Diseases: Common rust, northern corn leaf blight.
Management: Regularly inspect corn plants for pest and disease symptoms. Handpick and destroy infected corn ears or caterpillars. Consider planting disease-resistant corn varieties. Use organic insecticides or biological controls if necessary.
Beans:
Common pests: Aphids, bean leaf beetles, Mexican bean beetles.
Diseases: Anthracnose, powdery mildew.
Management: Monitor bean plants for pest activity and employ physical methods such as handpicking insects. Introduce beneficial insects like ladybugs or lacewings to control aphids. Practice proper spacing between plants for good air circulation, which reduces the risk of disease. Apply organic fungicides if necessary.
Squash:

Common pests: Squash bugs, cucumber beetles, squash vine borers.
Diseases: Powdery mildew, bacterial wilt.
Management: Regularly inspect squash plants for pest damage and remove or destroy affected leaves or insects. Use floating row covers during the early growth stages to protect plants from pests. Monitor for squash vine borers and take preventive measures such as placing aluminum foil around the base of the stems. Apply organic fungicides for powdery mildew prevention.
Additionally, practicing companion planting with the three sisters can help deter certain pests. For example, interplanting marigolds or nasturtiums with the three sisters can repel pests like aphids and beetles.
How to harvest the Three Sisters crops:
Corn (Maize): Harvesting time for corn depends on the variety and maturity period, which can range from 60 to 100 days. The corn is ready for harvest when the ears feel firm and the husks have dried and turned brown. Gently pull back the husks to check if the kernels are plump and fully formed. Use a sharp knife or shears to cut the ears from the stalks, leaving a short stem attached. Harvesting corn at its peak of ripeness ensures the best flavor and texture.
Beans (Runner Beans): The beans can be harvested when the pods are filled with mature beans but still tender. This is typically about 2 to 3 weeks after the corn harvest. Look for firm, plump pods that are still green. Avoid overripe pods that have turned yellow or dried out. Hold the stem of the bean plant and carefully snap off the pods from the vines. Alternatively, you can use scissors or a knife to cut the pods.

Squash (Pumpkin or Squash): Harvesting time for squash depends on the specific variety and maturity period, which can range from 70 to 120 days. The squash is ready for harvest when the skin has hardened and developed a deep color. The stem should be tough and dry. Use a sharp knife or shears to cut the squash from the vines, leaving a short stem attached. Handle the squash carefully to avoid damaging the skin.
