• Harvesting Considerations: Sweet potatoes require digging, which could disturb basil and zinnias if not spaced appropriately.

Practical Solutions:

• Use mulch to retain soil moisture and reduce competition.
• Implement drip irrigation to manage water needs efficiently.
• Space plants adequately to ensure airflow and reduce disease risk.

Planting Tips & Best Practices

• Optimal Spacing: Maintain recommended spacing from the table to prevent overcrowding.
• When to Plant: Plant after the last frost when the soil temperature is consistently warm.
• Container vs. Garden Bed: Sweet potatoes need more space, so garden beds are preferable, but basil and zinnias can thrive in containers.
• Soil Preparation: Ensure well-drained, nutrient-rich soil. Consider adding compost to improve soil structure.
• Additional Companion Plants: Marigolds and nasturtiums also work well with sweet potatoes and basil, providing further pest deterrence.
