Can You Plant Lettuce, Radishes, and Calendula Together?

Companion planting is a time-honored gardening technique that involves growing different plants together to enhance growth, deter pests, and maximize space. If you’re considering planting lettuce, radishes, and calendula together, you might be curious about their compatibility and benefits. This article will explore whether these plants make good companions and provide practical tips for success.

Compatibility Analysis

Yes, you can plant lettuce, radishes, and calendula together. These plants complement each other well, offering a harmonious blend of benefits. Lettuce and radishes are cool-season crops that thrive in similar conditions, while calendula, with its vibrant flowers, adds a pop of color and attracts beneficial insects.

Growth Requirements

• Lettuce and Radishes: Both prefer cool temperatures and can be planted in early spring or fall. They have similar water and soil needs, making them compatible companions.
• Calendula: While calendula enjoys full sun, it can tolerate partial shade, making it adaptable to the conditions preferred by lettuce and radishes.

Pest Control

Calendula acts as a natural pest deterrent, attracting beneficial insects like ladybugs and lacewings that prey on aphids, a common pest for lettuce and radishes. Additionally, its bright flowers can distract pests, reducing damage to the vegetables.

Nutrient Needs and Spacing

Lettuce and radishes have shallow root systems, allowing them to coexist without competing for nutrients. Calendula’s deeper roots can access nutrients lower in the soil, complementing the needs of its companions.
