Can You Plant Carrots, Nasturtiums, and Calendula Together?

Companion planting is a well-regarded practice among gardeners seeking to enhance plant growth and deter pests naturally. Carrots, nasturtiums, and calendula are often considered for this technique due to their potential compatibility. In this article, you’ll learn whether these plants can thrive together, the benefits and challenges of planting them in proximity, and best practices for successful cultivation.

Compatibility Analysis

Yes, you can plant carrots, nasturtiums, and calendula together. These plants complement each other well in a garden setting. Carrots benefit from the pest-repelling properties of nasturtiums and calendula, which can deter aphids and other insects. Additionally, nasturtiums attract beneficial insects such as pollinators, which can enhance the overall health of your garden.

Key factors that contribute to their compatibility include similar sunlight and soil requirements, as well as their ability to coexist without competing excessively for resources. Carrots grow underground, while nasturtiums and calendula spread above ground, making efficient use of space.
