• Soil Health Benefits: The combination of shallow and deep roots helps improve soil structure and nutrient cycling.

• Pollinator Attraction: Sweet potato flowers can attract pollinators, indirectly benefiting nearby lettuce by creating a thriving garden ecosystem.

Potential Challenges

While there are benefits, there are also challenges to consider:

• Competition for Resources: Although they have different nutrient needs, competition for water can be an issue if not managed properly.

• Different Watering Needs: Lettuce requires consistent moisture, whereas sweet potatoes are more drought-tolerant. Adjust watering practices accordingly.

• Disease Susceptibility: Both plants can be susceptible to fungal diseases in overly wet conditions, so ensure proper spacing and airflow.

• Harvesting Considerations: Care must be taken not to disturb sweet potato vines when harvesting lettuce.

To overcome these challenges, consider using mulch to retain soil moisture and manage water distribution effectively.
