Zucchinis are simple and easy to grow, making them a favorite among gardeners. However, to maximize your chances of a successful harvest, it’s important to choose the right companion plants.

Zucchinis belongs to the Cucurbitaceae family. These plants thrive in sunny, sheltered locations and are heavy feeders, requiring a lot of nutrients to produce their bountiful yields. Despite their vigorous growth, zucchinis can still fall victim to various pests and diseases, significantly impacting their productivity.

To ensure your zucchini crop remains healthy and productive, select companion plants that complement their growth requirements and offer protective benefits. Here are 15 best companion plants for your zucchini plants.
