Can You Plant Tomatoes, Cabbage, and Rosemary Together?

Companion planting is a time-honored gardening practice that involves growing different plants together to enhance growth, deter pests, and maximize space. When considering planting tomatoes, cabbage, and rosemary together, it’s crucial to understand their compatibility and how they can benefit—or hinder—each other’s growth. In this article, you’ll learn about the compatibility of these plants, their growing requirements, and the benefits and challenges of planting them together.

Compatibility Analysis

Can you plant tomatoes, cabbage, and rosemary together? The short answer is NO. While tomatoes and rosemary can thrive together, cabbage is not an ideal companion for either. Here’s why:

• Tomatoes and Rosemary: These two plants can coexist well. Rosemary can help deter pests that commonly affect tomatoes, such as aphids and hornworms, thanks to its strong aromatic oils. Both plants prefer full sun and well-drained soil, making them compatible in terms of growth requirements.

• Cabbage: Cabbage, on the other hand, has different needs and can attract pests that are harmful to tomatoes, such as cabbage worms. Additionally, cabbage requires more water and can create a more humid environment, which is not ideal for rosemary.

Key Compatibility Factors

• Growth Requirements: Tomatoes and rosemary both prefer full sun and well-drained soil, whereas cabbage can tolerate partial shade and prefers more moisture.
• Pest Control: Rosemary can deter pests from tomatoes, but cabbage can attract pests that harm tomatoes.
• Nutrient Needs: Cabbage is a heavy feeder and can compete with tomatoes for nutrients, whereas rosemary is less demanding.
• Spacing: Cabbage’s large leaves can overshadow tomatoes and rosemary, limiting their access to sunlight.
