• Pollinator Attraction: Zinnias are known for attracting bees and butterflies, essential for pollination.

Potential Challenges

While these plants can coexist well, there are potential challenges:

• Competition for Resources: Ensure adequate spacing to prevent competition for light and nutrients.
• Different Watering Needs: Monitor soil moisture to cater to the specific needs of each plant.
• Disease Susceptibility: Tomatoes are prone to blight, so maintain good air circulation and practice crop rotation.
• Harvesting Considerations: Be mindful of the space needed for harvesting tomatoes without damaging nearby plants.

To overcome these challenges, consider mulching to retain soil moisture and using drip irrigation for precise watering.

Planting Tips & Best Practices
