The Three Sisters
The thee sisters consist of the following plants and provide us with essential nutarians:
Corn is a good source of carbohydrates, dietary fiber, and vitamin B6. It also contains small amounts of other vitamins and minerals, including thiamin, niacin, folate, and potassium.
Beans are a good source of plant-based protein, dietary fiber, and a range of vitamins and minerals, including folate, iron, magnesium, and potassium. They are also rich in antioxidants and phytonutrients, which have been linked to a range of health benefits.
Squash is a good source of dietary fiber, vitamin C, and several minerals, including potassium and magnesium. It is also rich in antioxidants, which can help to protect the body against damage from free radicals.
Soil Benefits:
Nitrogen fixation: Beans are nitrogen fixers, meaning they have the ability to convert atmospheric nitrogen into a form of nitrogen that plants can use. This process adds nitrogen to the soil, which is a critical nutrient for plant growth.
Soil fertility: Squash plants have wide leaves that provide shade, which helps to retain soil moisture and keep the soil cool. As the squash plants decompose, they add organic matter to the soil, which improves soil fertility.
Soil structure: The deep root systems of the three sisters help to break up compacted soil, which improves soil structure and allows water and nutrients to penetrate more easily
The three sisters planting method can help to control pests in several ways:
Physical barriers: The prickly leaves of the squash plant can act as a physical barrier to deter pests from accessing the other plants in the garden. The leaves can also provide shade, which can reduce the likelihood of pest infestations by keeping the soil cool and moist.
Companion planting: The three sisters planting method involves planting corn, beans, and squash together in the same garden bed. This companion planting technique can help to reduce pest populations by creating a diverse ecosystem that is less favorable to pests. For example, beans can release chemicals that repel pests, while corn can provide a support structure for the climbing beans.
Biological controls: The three sisters planting method can also help to promote the presence of beneficial insects and other organisms that can help to control pest populations. For example, ground beetles are natural predators of pests like slugs and snails, while ladybugs and lacewings can help to control aphids.
