Can You Plant Peas, Cabbage, and Lemongrass Together?

Companion planting is a popular gardening technique that involves strategically growing different plants together to improve growth, deter pests, and maximize garden space. Gardeners often wonder if they can plant peas, cabbage, and lemongrass together. In this article, we’ll explore the compatibility of these plants and provide practical tips for growing them successfully in your vegetable garden.

Compatibility Analysis

Can you plant peas, cabbage, and lemongrass together? The short answer is yes, but with some considerations. Each plant has unique growth requirements and benefits that can complement one another when managed carefully.

Growth Requirements

• Peas thrive in cool weather and prefer well-drained soil with a pH of 6.0 to 7.5. They enjoy full sun but can tolerate partial shade.
• Cabbage also favors cool weather and requires rich, well-drained soil with a pH of 6.0 to 7.5. It needs full sun for the best growth.
• Lemongrass prefers warm climates and well-drained soil with a pH of 5.0 to 8.0. It requires full sun and thrives in warmer temperatures.

Pest Control and Nutrient Needs

• Peas can benefit from the pest-repellent properties of lemongrass, which deters insects with its strong scent.
• Cabbage may benefit from the nitrogen-fixing properties of peas, which enrich the soil.
• Lemongrass acts as a natural pest deterrent, making it a good companion for both peas and cabbage.

Spacing

Proper spacing is crucial to ensure that each plant receives adequate sunlight and nutrients. While peas can climb, cabbage and lemongrass need more ground space.
