What Makes Good Companion Plants for Zucchini and Squash
The best companion plants for zucchini and squash include beans and corn, a classic combination that benefits all three plants. This combination of plants has long been known as the “three sisters” approach and was practiced by the Seneca branch of the Iroquoian American Indian nation for centuries before Europeans arrived in North America and were taught the method.
Radishes, peas, peppermint, dill, parsley, oregano, and even flowers like marigolds or nasturtiums are a few other options for gardeners. Most importantly, zucchini and squash should grow with plants that also need regular watering but dont take up too much space.
Both zucchini and summer squash (members of the Cucurbia pepo species) require a lot of room in the garden, making it essential to find companion plants with opposite traits. They are also heavy feeders. Their broad leaves and vining nature offer shade which helps keep weeds in check and retain soil moisture which will benefit companion plants with those requirements. With this in mind, you can successfully choose plant companions that will thrive alongside these popular summer vegetables.
When plotting out your garden and choosing which plants to place near one another, youll want to to focus on selecting plants that have different growth habits so that they do not out-compete each other for sun and nutrients. For small gardens, strategic companion planting is recommended in order to conserve space and create as bountiful a yield as possible in a small footprint.
The Three Sisters
Beans, corn, and squash are the ultimate companion plants in the gardening world. This top-notch trio is typically planted together in indigenous peoples gardens and is collectively known as “the three sisters.” Legend describes these three plants as “gifts from the gods,” noting they should always be planted, eaten, and cherished together.
Each “sister” adds her own unique offering to the garden ecosystem. The beans (or any legume, including peas) pull nitrogen from the air and fix it into the soil. Nitrogen-fixing plants benefit all other plants—especially heavy feeders like zucchini and squash—by providing the nutrients they need to grow. Corn, with its tall, sturdy stalk, gives vining plants like beans a backbone on which to trellis themselves.
Additionally, both corn and squash have the same moisture and soil fertility requirements, making them impeccable neighbors. The ample growth of squash and zucchini plants shade the soil and prevent the infiltration of weeds, while their spiny leaves deter rodents who may enjoy a bean or sweet corn snack.
