Potential Challenges

• Competition for Resources: Tomatoes and sunflowers may compete for sunlight and nutrients, so proper spacing and fertilization are crucial.

• Different Watering Needs: Carrots require consistent moisture, whereas sunflowers are more drought-tolerant. Mulching can help balance these needs.

• Disease Susceptibility: Tomatoes are prone to fungal diseases, so ensure good air circulation by spacing plants appropriately.

• Harvesting Considerations: Harvesting carrots can be tricky if they’re planted too close to the large roots of sunflowers.

Solutions: Use mulch to retain soil moisture, practice crop rotation to prevent disease buildup, and ensure proper spacing to reduce competition.

Planting Tips & Best Practices

• Optimal Spacing: Keep tomatoes 18-24 inches apart, carrots 2-3 inches apart, and sunflowers 12-18 inches apart to ensure adequate space and resources.

• When to Plant: Plant sunflowers and tomatoes after the last frost, and carrots can be sown earlier in cooler soil.

• Container vs. Garden Bed: If space is limited, consider using deep containers for carrots and sunflowers, and a trellis for tomatoes.
