Can You Plant Radishes, Cabbage, and Sage Together?

Companion planting is a popular gardening technique where certain plants are grown together to enhance growth, deter pests, and maximize space. This article explores whether radishes, cabbage, and sage can be successfully planted together, offering insights into their compatibility, benefits, and challenges. By the end, you’ll have a clear understanding of how these plants interact and practical tips for growing them in your garden.

Compatibility Analysis

The short answer is: Yes, you can plant radishes, cabbage, and sage together, but with some considerations. Companion planting is not just about proximity; it’s about understanding the symbiotic relationships between plants. Radishes and cabbage belong to the Brassicaceae family and have similar growth requirements, making them good companions. Sage, an aromatic herb, can help repel pests that often target cabbage, such as cabbage moths. However, you must consider spacing and resource competition to ensure all plants thrive.

Key Factors

• Growth Requirements: Radishes and cabbage require full sun and well-drained soil, while sage prefers slightly drier conditions.
• Pest Control: Sage acts as a natural pest deterrent, helping to protect cabbage from common pests.
• Nutrient Needs: Cabbage is a heavy feeder, requiring more nutrients, while radishes and sage have moderate needs.
• Spacing: Proper spacing is crucial to prevent competition and ensure healthy growth.
