Growing Requirements Comparison Table

Benefits of Planting Together

• Pest Repellent Properties: Dill attracts beneficial insects like ladybugs and parasitic wasps, which help control aphid populations on tomatoes. Petunias deter pests such as leafhoppers and aphids.
• Improved Growth: Dill can enhance the growth of tomatoes by attracting pollinators and beneficial insects.
• Space Efficiency: The upright growth of tomatoes and dill, combined with the spreading habit of petunias, allows for efficient use of garden space.
• Soil Health: These plants can contribute to soil health by preventing erosion and maintaining organic matter.
• Pollinator Attraction: Petunias and dill flowers attract pollinators, which can improve overall garden productivity.

Potential Challenges

• Competition for Resources: Ensure adequate spacing to prevent competition for sunlight and nutrients.
• Different Watering Needs: While they have similar water requirements, monitor soil moisture to meet each plant’s needs.
• Disease Susceptibility: Tomatoes are prone to blight; ensure good air circulation to minimize disease risk.
• Harvesting Considerations: Dill can grow tall and may need staking to prevent overshadowing tomatoes.
• Solutions: Use mulch to retain moisture and consider vertical gardening techniques to optimize space and airflow.

Planting Tips & Best Practices
