Companion planting is a popular strategy among gardeners seeking to maximize the health and productivity of their gardens. By strategically placing certain plants together, gardeners can enhance growth, deter pests, and improve soil conditions. But can you plant onions, zucchini, and lavender together? This article explores their compatibility, offering insights into their growing requirements, benefits, challenges, and best practices for planting.

Compatibility Analysis

Can you plant onions, zucchini, and lavender together? The short answer is yes, with some considerations. While these plants can coexist in the same garden bed, their compatibility hinges on understanding their individual needs and how they interact.

Onions are known for their pest-repelling properties, which can benefit zucchini by deterring insects.
