Can You Plant Peas, Corn, and Calendula Together?

Companion planting is a popular gardening technique where different plants are grown together to enhance growth, deter pests, and improve yields. In this article, we explore whether peas, corn, and calendula can be successfully planted together, offering insights into their compatibility and practical tips for your garden.

Compatibility Analysis

Yes, you can plant peas, corn, and calendula together, and they can complement each other in various ways. Corn provides a natural trellis for peas to climb, while calendula acts as a pest deterrent. However, understanding their growth requirements and how they interact is crucial for success.

Growth Requirements

• Peas thrive in cooler temperatures and need support for climbing.
• Corn requires full sun and warm temperatures to grow tall and strong.
• Calendula prefers cooler weather but is versatile in different conditions.

Pest Control

Calendula attracts beneficial insects and repels pests, providing a natural defense for peas and corn. Peas can fix nitrogen in the soil, benefiting the corn’s growth.

Nutrient Needs and Spacing

Peas enrich the soil with nitrogen, which corn can utilize. However, ensure proper spacing to prevent competition for nutrients and sunlight.
