Can You Plant Peas, Broccoli, and Lemongrass Together?

Companion planting is an age-old gardening practice that involves growing different plants together for mutual benefits such as improved growth, pest control, and efficient use of space. In this article, we explore whether peas, broccoli, and lemongrass make good companions in the garden and provide practical advice for successful planting.

Compatibility Analysis

Yes, you can plant peas, broccoli, and lemongrass together, but with some considerations. These plants have varying growth requirements and benefits that can complement each other when managed properly.

• Peas: Legumes like peas fix nitrogen in the soil, which benefits heavy feeders like broccoli.
• Broccoli: This plant can benefit from the nitrogen provided by peas and may deter some pests that affect lemongrass.
• Lemongrass: Known for its aromatic properties, lemongrass can repel pests that might otherwise target peas and broccoli.

Key Compatibility Factors

• Growth Requirements: Peas and broccoli thrive in cooler temperatures, while lemongrass prefers warmth. This requires strategic planting times.
• Pest Control: Lemongrass can deter pests, while peas and broccoli have fewer pest issues when grown together.
