Can You Plant Tomatoes and Corn Together?

Companion planting is a popular gardening technique that involves growing different plants close together to enhance growth, deter pests, and maximize space. Tomatoes and corn are two common garden staples, but are they compatible companions? In this article, you’ll discover whether planting these two together is beneficial, along with tips and solutions for successful gardening.

Compatibility Analysis

Can you plant tomatoes and corn together? The short answer is: No. While both tomatoes and corn are beloved in gardens, they are not ideal companions. The main reason lies in their growth requirements and susceptibility to pests and diseases.

Tomatoes and corn both require full sun and well-drained soil, but corn is a heavy feeder that competes for nutrients, potentially depriving tomatoes. Moreover, both plants are susceptible to the same pests, such as the corn earworm and tomato hornworm, which can lead to increased pest pressure. Additionally, corn can overshadow tomatoes, inhibiting their growth due to its height.

• Space Efficiency: Maximizing garden space by interplanting.
• Soil Health Benefits: Diverse plantings can improve soil health.
• Pollinator Attraction: Companion plants can attract beneficial insects.

Potential Challenges

• Competition for Resources: Corn’s heavy nutrient needs can outcompete tomatoes.
