Can You Plant Onions, Limes, and Geraniums Together?

Companion planting is a popular gardening technique where different plants are grown together to enhance growth, deter pests, and maximize space. This article explores whether onions, limes, and geraniums can be planted together, providing insights into their compatibility and offering practical gardening advice.

Compatibility Analysis

Yes, you can plant onions, limes, and geraniums together, but with some considerations.

While these plants have different growth requirements, they can coexist with proper planning. Onions are known for their pest-repellent properties, which can benefit lime trees by deterring insects. Geraniums, on the other hand, attract pollinators, which can improve lime fruit production. However, it’s crucial to understand their individual needs to ensure a harmonious planting arrangement.

Key Factors

• Growth Requirements: Onions thrive in full sun, like limes, but geraniums can tolerate partial shade. Ensure your garden spot meets these light conditions.
• Pest Control: Onions repel aphids and other pests, benefiting limes. Geraniums attract beneficial insects, supporting the ecosystem.
• Nutrient Needs: While onions and limes prefer well-drained soil, geraniums can adapt to various soil types.
• Spacing: Adequate spacing is essential to prevent competition for nutrients and water.
