Compatibility Analysis

Can beans, lavender, and petunias be planted together? The answer is a qualified yes, but with some considerations. Each plant has unique growth requirements, and understanding these is key to successful companion planting.

• Beans are nitrogen-fixing plants that enrich the soil, benefiting surrounding plants. They prefer full sun, well-drained soil, and regular watering.
• Lavender thrives in full sun and well-drained, slightly alkaline soil. It is drought-tolerant and prefers less frequent watering.
• Petunias enjoy full sun and well-drained soil. They require regular watering, especially in hotter climates.

These plants can coexist if their specific needs are met. The key is to manage their differing water requirements and ensure proper spacing to avoid competition for nutrients.
