Zucchini and summer squash are great companions for a variety of plants.

The Three Sisters

The Three Sisters is a term used to describe an agricultural technique that utilizes three specific plants: corn, beans, and squash. These plants are planted together in close proximity and they each benefit the other in unique ways. Nitrogen-fixing plants like beans take nitrogen from the air and deposit it into the soil, benefitting all other plants in the vicinity. Corn gives vining plants like beans a backbone on which to trellis themselves, and both corn and squash have the same moisture and soil fertility requirements, making them impeccable neighbors. They grow tall, sturdy stalks that shade the soil and prevent weed infestation.
