Introduction

Companion planting is a method that enhances garden productivity by strategically growing plants together. Garlic, cauliflower, and nasturtiums are often considered for this practice due to their unique characteristics. In this article, you’ll learn whether these plants can thrive together and how to optimize their growth.
