Benefits of Planting Together

Planting sweet potatoes, sage, and nasturtiums together offers several advantages. Nasturtiums can repel aphids and attract pollinators, enhancing the overall health and productivity of the garden. Sage’s aromatic leaves deter certain pests, providing natural pest control. Additionally, the diverse growth habits of these plants maximize space efficiency, allowing you to make the most of your garden area. The combination can also improve soil health by promoting biodiversity and reducing disease risk.

Potential Challenges

Despite their compatibility, there are some challenges to consider. Sweet potatoes’ extensive root system may compete with sage and nasturtiums for nutrients and water. Additionally, these plants have slightly different watering needs, which could complicate maintenance. Disease susceptibility, particularly for sweet potatoes, may also be a concern.

To overcome these challenges, ensure proper spacing and monitor soil moisture levels. Mulching can help retain moisture and prevent weed growth, while regular observation will help identify potential issues early.

Planting Tips & Best Practices

• Optimal Spacing: Ensure adequate space between plants to minimize competition. Sweet potatoes need about 12–18 inches, sage 18–24 inches, and nasturtiums 10–12 inches.
• Timing: Plant after the last frost when the soil has warmed up, typically late spring.
• Container vs. Garden Bed: While garden beds are ideal, containers can work if they are large enough to accommodate root growth.
• Soil Preparation: Use well-drained soil enriched with organic matter. Avoid waterlogging by ensuring good drainage.
• Additional Companions: Consider adding marigolds or beans, which also pair well with these plants and offer additional pest control benefits.
