Can You Plant Broccoli, Petunias, and Calendula Together?

Companion planting is a popular gardening technique that involves growing different plants together to enhance growth, deter pests, and improve overall garden health. In this article, we’ll explore whether broccoli, petunias, and calendula can be successfully planted together. You’ll discover their compatibility, benefits, potential challenges, and practical tips for planting.

Compatibility Analysis

Yes, you can plant broccoli, petunias, and calendula together. These plants can coexist harmoniously, each offering unique benefits to the garden ecosystem. Broccoli, a cool-season vegetable, thrives with companions that deter pests and enhance growth. Petunias, known for their vibrant blooms, attract beneficial insects and repel certain pests. Calendula, with its bright flowers, also attracts pollinators and can help improve soil health.
