Can You Plant Onions, Tarragon, and Pomegranates Together?

Companion planting is a popular gardening technique that involves growing different plants together to enhance growth, improve flavor, and deter pests. In this article, we explore whether onions, tarragon, and pomegranates can be successfully planted together. You’ll learn about their compatibility, growing requirements, and potential challenges, as well as gain practical tips for a thriving garden.

Compatibility Analysis

The short answer is NO; onions, tarragon, and pomegranates are not ideally suited for planting together. This is primarily due to their differing growth requirements and potential competition for resources.

Onions and tarragon can be good companions as they share similar sunlight and soil preferences, and onions can help repel pests that might otherwise target tarragon. However, pomegranates are a different story. They are woody shrubs or small trees requiring different care than the herbaceous onions and tarragon. Pomegranates have a more extensive root system and different water needs, which can lead to competition and stress on the smaller plants.

Key Factors

• Growth Requirements: Onions and tarragon thrive in similar conditions, while pomegranates need more space and different care.
• Pest Control: Onions can repel certain pests, benefiting tarragon but not significantly affecting pomegranates.
• Nutrient Needs: Onions and tarragon have similar nutrient requirements, but pomegranates demand more nutrients due to their size.
• Spacing: Pomegranates require more space, potentially overshadowing smaller plants.
