Can You Plant Sweet Potatoes, Strawberries, and Cosmos Together?

Companion planting is a time-honored technique that gardeners use to enhance plant growth, deter pests, and maximize space. Sweet potatoes, strawberries, and cosmos are popular choices for many gardens. But can these three be planted together successfully? This article explores their compatibility and offers practical tips for gardeners.

Compatibility Analysis

Yes, you can plant sweet potatoes, strawberries, and cosmos together, but with some considerations. These plants can coexist harmoniously if you manage their specific needs.

Cosmos, a flowering plant, attracts pollinators and can tolerate diverse conditions, making it a good companion for both.

Key Factors:

• Growth Requirements: Sweet potatoes and strawberries both enjoy full sun, while cosmos can adapt to partial shade.
• Pest Control: Cosmos attracts beneficial insects that help control pests affecting strawberries and sweet potatoes.
• Nutrient Needs: While sweet potatoes are heavy feeders, strawberries and cosmos have moderate nutrient requirements.
• Spacing: Sweet potatoes need ample room to spread, whereas strawberries and cosmos can be planted more densely.
