Can You Plant Cabbage, Fennel, and Calendula Together?

Companion planting is a popular strategy among gardeners looking to maximize their garden’s potential. By understanding which plants thrive together, you can create a harmonious garden that benefits from natural pest control, improved growth, and resource efficiency. In this article, we’ll explore whether cabbage, fennel, and calendula make good companions and provide practical tips for growing them together.

Compatibility Analysis

The short answer is: No, planting cabbage, fennel, and calendula together is not ideal. While calendula is a beneficial companion for cabbage, fennel tends to be a poor companion for many plants, including cabbage. Here’s why:

• Cabbage and Calendula: Calendula is known for its pest-repelling properties, making it an excellent companion for cabbage. It attracts beneficial insects like ladybugs and hoverflies, which help control pests such as aphids.

• Fennel: Fennel is a notorious loner in the garden. It secretes a substance that can inhibit the growth of many plants, including cabbage. Its allelopathic properties make it incompatible with most vegetables.

• Growth Requirements: Cabbage and calendula share similar growth requirements, such as full sun and moderate water needs, whereas fennel prefers drier conditions and can compete for nutrients.
