Can You Plant Corn, Lavender, and Calendula Together?

Companion planting is a gardening technique that involves growing different plants in proximity to benefit one another. Gardeners often consider it to improve growth, deter pests, and maximize space. This article explores whether corn, lavender, and calendula can be planted together and what you need to know to make it work.

Compatibility Analysis

Can you plant corn, lavender, and calendula together? The short answer is YES, but with some considerations. While these plants can coexist, their differing needs require careful planning.

• Corn is a tall, sun-loving plant that demands rich, well-drained soil and consistent moisture. It grows best in warm climates and provides a natural windbreak or support for climbing plants.
• Lavender thrives in full sun and well-drained, slightly alkaline soil. It prefers drier conditions, making it a good companion for plants that do not require much water.
• Calendula is versatile, tolerating various soil types but preferring full sun and moderate water. Its bright flowers attract beneficial insects, aiding pollination.

Together, these plants can complement each other if their specific needs are managed carefully.

Growing Requirements Comparison Table

Benefits of Planting Together

1. Pest Repellent Properties: Lavender’s strong scent deters pests, while calendula attracts beneficial insects that prey on harmful bugs.
2. Improved Growth: Calendula can enhance soil health by attracting pollinators and improving nutrient availability.
3. Space Efficiency: Corn’s vertical growth allows for underplanting with lavender and calendula, maximizing garden space.
4. Soil Health Benefits: Calendula’s roots can improve soil structure, benefiting corn’s growth.
5. Pollinator Attraction: Calendula’s bright flowers draw pollinators, aiding the overall productivity of the garden.

Potential Challenges

1. Competition for Resources: Corn requires significant nutrients and water, which can compete with lavender’s preference for drier conditions.
2. Different Watering Needs: Lavender’s drought tolerance contrasts with corn’s high water demand.
3. Disease Susceptibility: Overwatering lavender can lead to root rot, especially when grown near water-loving corn.
4. Harvesting Considerations: Corn’s height may overshadow shorter plants if not spaced correctly.
5. Practical Solutions: Use drip irrigation to tailor water distribution, and apply mulch to retain soil moisture for corn while keeping lavender dry.

Planting Tips & Best Practices

• Optimal Spacing: Ensure corn is spaced at least 12-18 inches apart, with lavender and calendula interspersed to avoid shading.
• When to Plant: Start planting after the last frost when the soil is warm. Lavender can be planted slightly earlier in spring.
• Container vs. Garden Bed: Consider raised beds for better drainage, especially for lavender.
• Soil Preparation: Amend soil with compost for corn and ensure good drainage for lavender.
• Companion Plants: Consider adding sunflowers or beans, which pair well with corn and calendula.
