Can You Plant Cabbage, Blueberries, and Calendula Together?

Companion planting is a gardening technique that pairs plants to enhance growth, deter pests, and optimize space. In this article, we’ll explore whether cabbage, blueberries, and calendula make good neighbors in your garden, examining their compatibility and offering practical planting tips.

Compatibility Analysis

Can you plant cabbage, blueberries, and calendula together? The short answer is: yes, with some considerations. While these plants can coexist, understanding their individual needs is crucial for success.

• Growth Requirements: Cabbage, a cool-season vegetable, thrives in full sun and well-drained, fertile soil. Blueberries prefer acidic soil and consistent moisture, while calendula, a hardy annual, is adaptable but favors full sun and well-drained soil.

• Pest Control: Calendula can repel pests like aphids, benefiting cabbage. However, blueberries may not gain significant pest control advantages from calendula.

• Nutrient Needs and Spacing: Cabbage is a heavy feeder, requiring nitrogen-rich soil, whereas blueberries need low-nitrogen, acidic conditions. Calendula has moderate nutrient needs and can fit into spaces between cabbage plants.

• Timing: Plant cabbage in early spring or fall, blueberries in early spring, and calendula after the last frost.
• Container vs. Garden Bed: Blueberries often thrive in containers due to their specific soil requirements.
• Soil Preparation: Amend soil for blueberries with sulfur to lower pH, and use compost for cabbage and calendula.
• Companion Plants: Consider adding nasturtiums or marigolds, which also pair well with cabbage and calendula.
