Can You Plant Cabbage, Sweet Potatoes, and Tarragon Together?

Gardening enthusiasts often explore companion planting to enhance their vegetable gardens’ productivity and health. This technique involves growing different plants together to benefit from their symbiotic relationships. In this article, we’ll explore whether cabbage, sweet potatoes, and tarragon can be successfully planted together, examining their compatibility, benefits, and potential challenges.

Compatibility Analysis

Can you plant cabbage, sweet potatoes, and tarragon together? The short answer is NO. While cabbage and tarragon can coexist without significant issues, sweet potatoes present challenges due to differing growth requirements and potential competition for resources.

Growth Requirements and Compatibility

1. Cabbage prefers cooler temperatures and requires full sun with consistent moisture. It thrives in well-drained, fertile soil with a pH between 6.0 and 7.5.

2. Sweet Potatoes need warm temperatures, full sun, and sandy, well-drained soil with a pH of 5.0 to 6.5. They are sprawling plants that require ample space.

3. Tarragon grows well in full sun to partial shade and prefers well-drained soil with a pH of 6.5 to 7.5. Tarragon can withstand drier conditions compared to cabbage and sweet potatoes.

Key Factors

• Growth Requirements: Cabbage and tarragon share similar soil pH needs, but sweet potatoes prefer more acidic conditions.
• Pest Control: Tarragon can deter some pests, benefiting cabbage.
• Nutrient Needs: Sweet potatoes are heavy feeders, which may lead to competition with cabbage.
• Spacing: Sweet potatoes’ sprawling vines can overshadow cabbage and tarragon, limiting their growth.
