Additionally, sunflowers attract pollinators and beneficial insects that can help with pest control.

Key Factors:

• Growth Requirements: Lettuce and kale prefer cooler temperatures and can benefit from the shade provided by taller sunflowers.
• Pest Control: Sunflowers attract beneficial insects that prey on pests affecting lettuce and kale.
• Nutrient Needs: All three plants have moderate nutrient requirements, but sunflowers can be heavy feeders, so soil fertility should be monitored.
• Spacing: Adequate spacing is crucial to prevent competition for light and nutrients.
