Companion plants help your zucchini to grow better, taste better, and have fewer pest problems. In this post, I listed some best companion plants that you can grow with zucchini to protect them from pests and problems.

Let’s get started:

There are two types of squash that you can grow in the garden. One is a summer squash that is yellow squash or zucchini and the other is a winter squash that is pumpkins, butternut, and candy roster to name a few.

The popular three-sister method is the most efficient way to grow squash. This method was first used by North American tribes and it is still used for the great harvest.

In the three-sister gardening, we plant squash along with corns and beans. Corns and squash have similar soil requirements that make it easier to grow them together.

Beans are planted beside corn which grows with corn support. Actually, beans fix nitrogen in the soil that is beneficial for both zucchini and corn.

The winter squash planted around the corn helps to keep weeds down and helps to reduce pests like raccoons from damaging the corn.

Many experienced gardeners also claimed that planting three sisters together also increases the flavor of all three companions.
