Beans, peas and lentils are all legumes and are among the most versatile and nutritious foods available. Legumes are typically low in fat and high in fiber, folate, potassium, iron and magnesium. Beans and other legumes can be a healthy substitute for meat, which has more fat and cholesterol. Black beans are a staple in many Mexican and Brazilian dishes.

Many factors help plants to grow, including light, soil, water, and nutrients. What many gardeners overlook are the beneficial relationships that exist between plants, a growing method known as companion planting.
For example, one plant may deter garden pests that harm another species, while in return, that other species might enhance soil nutrients. Vegetables in particular see better yields, flavor, and pest and disease resistance when sited next to good neighbors. Conversely, certain combinations can result in poor performance.
Companion planting isn’t an exact science. Some combinations work better than others; factors such as weather and regional differences can impact effectiveness. Understanding how plants, insects, and organisms work together can reduce or eliminate the need for inorganic remedies, increase your gardening successes, and influence your plant choices.
Here are some key vegetables and herbs to consider, along with their beneficial helpers and plants to avoid. These are general recommendations; results may vary.

HISTORY OF COMPANION PLANTING:
THE THREE SISTERS
The concept of companion planting goes back hundreds of years. Indigenous Peoples planted corn, beans, and squash together, a symbiotic combination known as the Three Sisters.
Corn provides a natural trellis for climbing beans, while bean vines anchor the corn stalks, making them less prone to being blown over. Beans attract beneficial insects while boosting nitrogen levels in the soil, helping corn and squash to grow. The large leaves of squash suppress weeds and provide shade to cool the soil, slowing water evaporation. Tiny spines along the stems and leaves of squash deter predators and insect pests.
At the end of the growing season, the spent plants are worked back into the soil to provide nutrients for the following year.
