Can You Plant Peas, Radishes, and Cabbage Together?

Companion planting is a popular strategy among gardeners seeking to optimize their vegetable gardens. By selecting compatible plant pairings, you can enhance growth, deter pests, and make efficient use of space. In this article, you’ll learn whether peas, radishes, and cabbage can be planted together and how to maximize their benefits.

Compatibility Analysis

Yes, you can plant peas, radishes, and cabbage together, and here’s why. These three crops complement each other well due to their differing growth habits and requirements. Peas, being legumes, enrich the soil with nitrogen, which benefits heavy feeders like cabbage. Radishes grow quickly and can be harvested before the cabbage matures, minimizing competition. Additionally, radishes can deter common pests that affect cabbage.

Key Factors

• Growth Requirements: Peas prefer cooler temperatures and can provide shade for the soil, benefiting radishes and cabbage.
• Pest Control: Radishes can repel flea beetles, which are known to attack cabbage.
• Nutrient Needs: Peas fix nitrogen, improving soil fertility for cabbage.
• Spacing: Proper spacing ensures each plant receives adequate sunlight and nutrients.
