Can You Plant Kale, Nasturtiums, and Sunflowers Together?

Companion planting is a popular strategy among gardeners seeking to maximize their garden’s productivity and health. By pairing certain plants together, gardeners can enhance growth, deter pests, and make efficient use of space. In this article, we’ll explore whether kale, nasturtiums, and sunflowers can be successfully grown together, and what benefits or challenges this combination might present.

Compatibility Analysis

Yes, you can plant kale, nasturtiums, and sunflowers together, and they can complement each other in various ways. Sunflowers, with their tall stature, can provide partial shade that kale may appreciate during the hottest parts of the day. Nasturtiums not only add a splash of color but also act as a natural pest deterrent, attracting aphids away from kale. Key factors to consider include each plant’s growth requirements, pest control benefits, nutrient needs, and spacing.

Benefits of Planting Together

Planting kale, nasturtiums, and sunflowers together offers several benefits:

• Pest Repellent Properties: Nasturtiums are known for attracting aphids, which can help protect kale. They also repel whiteflies and squash bugs.
• Improved Growth: The partial shade from sunflowers can help kale thrive in hot climates.
• Space Efficiency: Sunflowers grow vertically, allowing nasturtiums to spread at their base and kale to fill in the gaps.
• Soil Health: Sunflowers have deep roots that can help break up soil, improving water penetration.
• Pollinator Attraction: All three plants attract pollinators, enhancing the biodiversity of your garden.

Potential Challenges

While these plants can be grown together, there are potential challenges to consider:

• Competition for Resources: Sunflowers can be heavy feeders, potentially competing with kale for nutrients.
• Watering Needs: Nasturtiums prefer drier soil compared to kale and sunflowers, requiring careful watering management.
• Disease Susceptibility: Close planting can increase the risk of fungal diseases.
• Harvesting Considerations: Ensure adequate space for easy access to harvest kale without damaging nasturtiums or sunflowers.

Practical Solutions

To overcome these challenges, consider using mulch to retain soil moisture and manage watering schedules to meet each plant’s needs. Regularly check for signs of nutrient deficiency and apply organic fertilizers as needed.

Planting Tips & Best Practices

• Optimal Spacing: Plant sunflowers at the back of the bed, with nasturtiums and kale in front, allowing 12-18 inches between kale plants and 10-12 inches for nasturtiums.
• Timing: Plant in spring after the last frost. Kale can be planted earlier, followed by sunflowers and nasturtiums.
• Container vs. Garden Bed: While possible in large containers, garden beds offer better space for root growth.
• Soil Preparation: Amend soil with compost to ensure fertility and good drainage.
• Companion Plants: Consider adding marigolds or basil, which also pair well with these plants.
