Benefits of Planting Together

1. Pest Repellent Properties: Parsley attracts beneficial insects that prey on pests harmful to tomatoes and beans.
2. Improved Growth: Beans enrich the soil with nitrogen, boosting tomato growth.
3. Space Efficiency: Vertical growth of beans maximizes space, allowing parsley to spread below.
4. Soil Health: Diverse root structures improve soil aeration and nutrient distribution.
5. Pollinator Attraction: Parsley’s flowers attract pollinators, enhancing fruit set in tomatoes.

Potential Challenges

• Resource Competition: Ensure adequate spacing to prevent competition for sunlight and nutrients.
• Watering Needs: Tomatoes need consistent watering; monitor soil moisture to accommodate all plants.
• Disease Susceptibility: Rotate crops yearly to prevent soil-borne diseases.
