Potential Challenges

While there are benefits to planting these crops together, challenges can arise:

• Resource Competition: Sweet potatoes’ extensive root systems may compete with onions and strawberries for nutrients and water.
• Watering Needs: Although all three require moderate watering, sweet potatoes may need more frequent watering during hot spells.
• Disease Susceptibility: Strawberries can be prone to fungal diseases, which may spread if not managed properly.
• Harvesting Considerations: Harvesting onions and strawberries may disturb sweet potato vines, so careful planning is needed.

To overcome these challenges, consider using raised beds or containers to better manage space and resources.

Planting Tips & Best Practices

• Optimal Spacing: Ensure proper spacing to prevent overcrowding—plant onions 4-6 inches apart, strawberries 12-18 inches apart, and sweet potatoes 12-18 inches apart.
• Timing: Plant onions in early spring, strawberries in early spring or fall, and sweet potatoes after the last frost.
• Containers vs. Garden Beds: Containers can help manage space and soil conditions, especially for sweet potatoes.
• Soil Preparation: Amend soil with organic matter to improve drainage and nutrient content.
• Additional Companions: Consider adding marigolds or nasturtiums to further deter pests and attract pollinators.
