Can You Plant Tomatoes, Nasturtiums, and Calendula Together?

Introduction

Companion planting is a time-honored gardening technique that combines different plants to improve growth, deter pests, and optimize space. Tomatoes, nasturtiums, and calendula are popular choices for this method. In this article, you’ll discover whether these plants thrive together and how to maximize their benefits in your garden.

Compatibility Analysis

Yes, you can plant tomatoes, nasturtiums, and calendula together. These plants complement each other well, making them excellent companions in the garden. Tomatoes require full sun and well-drained soil, conditions that both nasturtiums and calendula can tolerate. Nasturtiums are known for their pest-repelling properties, particularly against aphids, which can be beneficial for tomatoes. Calendula, on the other hand, attracts pollinators and can help improve soil health by acting as a trap crop for pests.

Key Factors

• Growth Requirements: All three plants prefer full sun and can adapt to similar soil conditions.
• Pest Control: Nasturtiums repel aphids and other pests, while calendula attracts beneficial insects.
• Nutrient Needs: They have compatible nutrient requirements, ensuring they don’t compete excessively for resources.
• Spacing: Adequate spacing is crucial to prevent overcrowding and ensure healthy growth.
