Can You Plant Garlic, Calendula, and Cosmos Together?

Companion planting is a popular gardening technique that involves growing different plants together to enhance growth, deter pests, and maximize space. Gardeners often wonder if garlic, calendula, and cosmos can be planted together. This article will explore their compatibility, growing requirements, benefits, challenges, and best practices for planting these three plants together.

Compatibility Analysis

Yes, you can plant garlic, calendula, and cosmos together! These plants are generally compatible due to their complementary growth requirements and benefits. Garlic is known for its pest-repelling properties, calendula attracts beneficial insects, and cosmos adds aesthetic appeal with its vibrant blooms. However, understanding their individual needs is crucial for successful companion planting.

Growth Requirements

• Garlic: Prefers full sun, well-drained soil, and moderate watering. It thrives in a pH range of 6.0 to 7.0.
• Calendula: Enjoys full sun to partial shade and requires regular watering. It grows well in neutral to slightly acidic soil (pH 6.0 to 7.0).
• Cosmos: Needs full sun and tolerates poor soil conditions. It prefers a slightly acidic to neutral pH (6.0 to 7.0) and requires minimal watering.

Pest Control and Nutrient Needs

Garlic’s natural sulfur compounds repel pests like aphids and beetles, benefiting both calendula and cosmos. Calendula attracts pollinators and predatory insects that control aphid populations, while cosmos provides a habitat for beneficial insects. These plants do not compete heavily for nutrients, making them suitable companions.

Spacing Considerations

Proper spacing is crucial to prevent competition for resources. Garlic requires about 6 inches between plants, calendula needs 12 inches, and cosmos should be spaced 12 to 18 inches apart. This spacing allows each plant to access sufficient sunlight and nutrients.
