Can You Plant Tomatoes, Dill, and Calendula Together?

Companion planting is a popular strategy among gardeners looking to maximize their space and improve plant health. By strategically placing plants that benefit each other, you can create a thriving garden ecosystem. In this article, we’ll explore the compatibility of tomatoes, dill, and calendula, and provide practical tips for growing them together.

Compatibility Analysis

Yes, you can plant tomatoes, dill, and calendula together. These plants complement each other well in a garden setting. Tomatoes, with their tall and bushy growth, provide shade and support for dill, which can grow tall and feathery. Calendula, a low-growing plant, acts as a natural mulch, helping to retain soil moisture and suppress weeds. This trio works harmoniously by meeting each other’s growth requirements and offering pest control benefits.

Key Factors

• Growth Requirements: Tomatoes and dill thrive in similar conditions, preferring full sun and well-drained soil. Calendula is adaptable and can grow in partial shade if needed.
• Pest Control: Dill attracts beneficial insects like ladybugs and predatory wasps, which help control tomato pests. Calendula can repel aphids and nematodes.
• Nutrient Needs: All three plants have moderate nutrient requirements, making them compatible in terms of soil fertility.
• Spacing: Proper spacing ensures each plant has enough room to grow without competing for resources.
