Can You Plant Eggplant and Nasturtiums Together?

Companion planting is a popular technique among gardeners seeking to enhance plant growth, deter pests, and optimize garden space. Eggplants and nasturtiums are often considered for such pairings. This article explores whether these two plants can grow harmoniously and offers practical tips for successful planting.

Compatibility Analysis

Yes, you can plant eggplant and nasturtiums together. This combination works well due to their complementary characteristics. Eggplants thrive in warm conditions and require full sun, similar to nasturtiums, which are known for their vibrant flowers and pest-repelling properties. Nasturtiums can deter aphids and other pests that often target eggplants, providing natural pest control. Additionally, both plants have similar soil and water needs, making them compatible companions in the garden.

Key Factors

• Growth Requirements: Both prefer full sun and well-drained soil.
• Pest Control: Nasturtiums repel aphids, whiteflies, and other pests.
• Nutrient Needs: Both benefit from nutrient-rich soil with moderate feeding.
• Spacing: Adequate spacing ensures both plants have room to grow without competition.

Benefits of Planting Together

Planting eggplants and nasturtiums together offers several advantages:

• Pest Repellent Properties: Nasturtiums deter common eggplant pests, reducing the need for chemical pesticides.
• Improved Growth: By attracting beneficial insects, nasturtiums can enhance pollination and growth for eggplants.
• Space Efficiency: Nasturtiums’ spreading habit can serve as a living mulch, conserving soil moisture and suppressing weeds.
• Soil Health: Nasturtiums can improve soil health by fixing nitrogen and adding organic matter as they decompose.
• Pollinator Attraction: The bright flowers of nasturtiums attract pollinators, aiding in the fruiting of eggplants.

Potential Challenges

While this pairing is generally beneficial, some challenges may arise:

• Resource Competition: Ensure adequate spacing to prevent competition for light and nutrients.
• Watering Needs: While both need moderate watering, monitor soil moisture to avoid overwatering nasturtiums.
• Disease Susceptibility: Both plants can be susceptible to fungal diseases; ensure good air circulation.
• Harvesting Considerations: Be mindful of nasturtium vines when harvesting eggplants to avoid damaging plants.

Practical Solutions

• Use mulch to retain soil moisture and reduce competition.
• Regularly prune nasturtiums to prevent them from overwhelming eggplants.
• Rotate crops annually to prevent disease buildup in the soil.

Planting Tips & Best Practices

• Optimal Spacing: Plant eggplants 18-24 inches apart and nasturtiums 10-12 inches apart to allow for healthy growth.
• Timing: Plant after the last frost date when the soil has warmed.
• Container vs. Garden Bed: Both can be grown in containers, but ensure adequate pot size and drainage.
• Soil Preparation: Enrich soil with compost before planting to provide essential nutrients.
• Companion Plants: Consider adding basil or marigolds, which also complement eggplants and nasturtiums.
