Can You Plant Eggplant, Lemons, and Nasturtiums Together?

Companion planting is a popular technique among gardeners aiming to maximize their garden’s health and productivity. When considering whether to plant eggplants, lemons, and nasturtiums together, one must evaluate their compatibility. This article will guide you through their compatibility, benefits, challenges, and best practices for growing these plants together.

Compatibility Analysis

The short answer is YES, you can plant eggplant, lemons, and nasturtiums together, but with some considerations. These plants can complement each other under the right conditions, primarily due to their differing growth habits and benefits they offer each other.

• Eggplants thrive in full sun and require well-draining soil. They are susceptible to pests like aphids and flea beetles.
• Lemons also prefer full sun and well-draining soil. They can act as a natural barrier due to their larger size.
• Nasturtiums are excellent companions as they repel pests and attract beneficial insects. They can tolerate partial shade and are not demanding in terms of soil quality.

Key Factors

• Growth Requirements: All three plants prefer sunny locations, but nasturtiums can tolerate some shade.
• Pest Control: Nasturtiums repel pests that commonly affect eggplants, such as aphids.
• Nutrient Needs: While eggplants and lemons have higher nutrient needs, nasturtiums are less demanding.
• Spacing: Adequate spacing is crucial to prevent competition for nutrients and sunlight.

Benefits of Planting Together

• Pest Repellent Properties: Nasturtiums act as a trap crop, attracting aphids away from eggplants.
• Improved Growth: The diverse root systems help in utilizing different soil layers, improving nutrient uptake.
• Space Efficiency: Nasturtiums can fill in spaces between larger plants, maximizing garden space.
• Soil Health: Nasturtiums improve soil health by fixing nitrogen.
• Pollinator Attraction: Nasturtium flowers attract bees and other pollinators, benefiting lemon trees.

Potential Challenges

• Resource Competition: Eggplants and lemons may compete for nutrients if not spaced properly.
• Different Watering Needs: Lemons may require more water than nasturtiums.
• Disease Susceptibility: Overcrowding can lead to increased humidity and disease spread.
• Harvesting Considerations: Ensure easy access to each plant for harvesting.
• Practical Solutions: Use mulch to retain moisture and plant nasturtiums on the periphery to minimize competition.

Planting Tips & Best Practices

• Optimal Spacing: Ensure at least 18 inches between eggplants and 10 feet for lemon trees. Nasturtiums can be interplanted closer.
• Timing: Plant after the last frost when the soil has warmed up.
• Container vs. Garden Bed: Container planting is feasible for eggplants and nasturtiums but challenging for lemon trees.
• Soil Preparation: Enrich soil with compost before planting to provide necessary nutrients.
• Companion Plants: Consider adding basil or marigolds for additional pest control and flavor enhancement.
