Before you plant a couple of tomato plants together, here is what you need to know and keep in mind.

Planting Multiple Tomato Plants Together

  • Theory: Planting two tomato plants close together in a larger hole might increase root mass, potentially enhancing water and nutrient uptake.
  • Concerns: Reduced space per plant could limit growth and decrease sunlight exposure due to shading from adjacent plants. There’s a balance between increased root space and the potential drawbacks of restricted growth conditions.

Growing Different Varieties Together

  • Spacing: About two feet is recommended between tomato plants to ensure they get enough nutrients and space to grow robustly.
  • Cross-Pollination: While tomatoes generally self-pollinate, different varieties planted close together might cross-pollinate due to insect activity or other factors. This is a crucial consideration if you’re saving seeds, as it might affect the genetic purity of future plants.
  • Diversity Benefits: A mix of tomato varieties can yield a diverse and interesting harvest, offering various colors, flavors, and textures.

Cross-Pollination and Disease Resistance

  • Importance of Diversity: Mixing varieties might help manage disease spread, as some varieties are more resistant to certain pathogens. This strategy could safeguard against total crop loss.
  • Growth Habits and Requirements: Varieties have unique needs and habits. Proper spacing is vital for air circulation, reducing disease risk and supporting healthy plant development.

Research Insights on Spacing

  • General Guidance: Adequate spacing is crucial, with two feet or more suggested to promote good air flow and disease prevention.
  • Density Considerations: Some studies suggest that staked tomatoes might be planted closer within rows if rows are spaced adequately apart. This method could impact fruit flavor positively, as some believe stress from closer spacing enhances taste.
  • Study Findings: Research varies, but some indicate no significant difference in yield, maturity, or fruit size with spacing ranging from one to three feet, particularly for early, small-vined varieties. Closer spacing might sometimes advance maturity or affect fruit size.

The Conclusion

The cultivation of tomatoes, whether planting multiple plants together or managing different varieties in proximity, involves careful consideration of spacing, potential for cross-pollination, and variety-specific growth needs.

The goal is to balance the benefits of increased root space or variety diversity with the potential challenges, such as reduced sunlight exposure, disease management, and ensuring genetic integrity for seed saving.

At the end of the day, you will need to try this yourself and learn from your own experiences whether you want to plant 2 to 3 tomato plants together.
