Can You Plant Tomatoes, Peas, and Calendula Together?

Companion planting is a popular strategy among gardeners to enhance growth, deter pests, and maximize space. This article explores whether tomatoes, peas, and calendula can thrive together in your garden. You’ll discover their compatibility, growing requirements, and the benefits and challenges of planting them together.

Compatibility Analysis

Yes, you can plant tomatoes, peas, and calendula together. These plants complement each other well due to their differing growth habits and benefits they offer. Tomatoes and peas are classic companions; peas fix nitrogen in the soil, which tomatoes, heavy feeders, utilize. Calendula, known for its pest-repellent properties, adds another layer of protection and beauty to the garden.

Key Factors
