Can You Plant Garlic, Beets, and Cosmos Together?

Companion planting is a time-honored gardening practice that involves growing certain plants together to enhance growth, deter pests, and maximize space. In this article, we’ll explore whether garlic, beets, and cosmos can be successful companions in your garden. You’ll learn about their compatibility, growing requirements, benefits, challenges, and tips for planting them together.

Compatibility Analysis

Can you plant garlic, beets, and cosmos together? Yes, these plants can be grown together, but with some considerations. Garlic and beets are excellent companions, as garlic can help repel pests like aphids that often target beets. Cosmos, while not directly beneficial to garlic or beets, adds beauty and attracts pollinators, which can benefit the overall garden ecosystem.

Key Factors

• Growth Requirements: Garlic prefers well-drained soil and full sun, which aligns with the needs of beets. Cosmos also thrives in full sun and can tolerate poorer soil conditions, making it a flexible companion.
• Pest Control: Garlic acts as a natural pest deterrent, which is beneficial for beets. Cosmos attracts beneficial insects, such as ladybugs and lacewings, which can help control pest populations.
• Nutrient Needs and Spacing: While garlic and beets have similar nutrient requirements, cosmos may need additional nutrients if the soil is poor. Proper spacing is crucial to prevent competition for resources.
