Phaseolus, commonly known as beans, are versatile annual legumes that can be grown in a variety of climates and soil types. When selecting companion plants for Phaseolus, consider plants that can complement their growth habit, provide contrast in color, texture, and height, and improve overall growing conditions. Here are some suggestions for companion plants:
Corn: Beans can use corn stalks as natural trellises to climb, while beans help fix nitrogen in the soil, benefiting the corn. This combination is part of the “Three Sisters” planting method, a traditional Native American companion planting technique.
Squash: When planted together with beans and corn, squash forms the third component of the “Three Sisters” planting method. The large, broad leaves of squash help shade the soil, conserving moisture and suppressing weeds.
Marigolds: These brightly colored flowers can help repel pests like bean beetles and nematodes, while attracting pollinators to your garden. They also add a pop of color to your bean planting.
Nasturtium: These flowers can help deter pests like aphids and bean beetles, while their bright blooms attract pollinators. They can also provide a beautiful contrast to the green foliage of beans.
Potatoes: Beans can help fix nitrogen in the soil, benefiting the growth of potatoes. Additionally, beans can help repel Colorado potato beetles.
Tomatoes: The strong scent of tomatoes can help repel pests that may target beans, while beans help fix nitrogen in the soil, which can benefit tomatoes.
Peas: Both peas and beans are legumes that fix nitrogen in the soil, and they can be grown together to create a lush, productive planting.
Lettuce: The low-growing habit of lettuce makes it a good ground cover, helping to suppress weeds and conserve soil moisture around bean plants.
Carrots: Beans can help fix nitrogen in the soil, benefiting the growth of carrots, while carrots can help break up compacted soil, improving root growth for beans.
Borage: The blue, star-shaped flowers of borage can create a stunning contrast with the green foliage of beans, while attracting pollinators and beneficial insects to your garden.
When choosing companion plants for Phaseolus, consider their sunlight, water, and soil requirements to ensure compatibility. Additionally, be mindful of the potential for competition for resources between the companion plants and your beans, ensuring that both have enough space to grow and thrive. It’s also essential to avoid planting beans near members of the onion family (Alliums), as they can inhibit bean growth.
