Can You Plant Tomatoes, Onions, and Figs Together?

Companion planting is a popular gardening technique that involves growing different plants together to enhance growth, improve flavor, and deter pests. If you’re considering planting tomatoes, onions, and figs together, you’re likely curious about their compatibility and the benefits of this combination. In this guide, we’ll explore whether these plants can thrive together and provide tips for successful companion planting.

Compatibility Analysis

Can you plant tomatoes, onions, and figs together? The answer is mostly NO for optimal growth. While tomatoes and onions can be excellent companions, figs are a different story due to their distinct growth requirements and potential to overshadow smaller plants.

Why Tomatoes and Onions Work Together

• Pest Control: Onions can repel pests that typically target tomatoes, such as aphids and certain beetles, making them a beneficial companion in the vegetable garden.
• Nutrient Needs: Both tomatoes and onions have similar nutrient requirements, thriving in well-drained, fertile soil.
• Spacing: Onions can be planted between tomato plants, maximizing space and improving air circulation.

Why Figs Are Not Ideal Companions

• Growth Requirements: Figs require more space and have a sprawling growth habit, which can overshadow and compete with smaller plants like tomatoes and onions.
• Nutrient Competition: Figs have deep roots that can outcompete other plants for nutrients and water.
• Sunlight Needs: All three plants require full sun, but figs’ height and spread can limit sunlight for the other two.
