Can You Plant Onions, Figs, and Nasturtiums Together?

Companion planting is a popular gardening technique that involves growing different plants close together for mutual benefits. Gardeners often consider this method to enhance growth, deter pests, and optimize space. But can onions, figs, and nasturtiums be planted together? This article will explore their compatibility, growing requirements, benefits, challenges, and best practices for planting these three diverse plants together.

Compatibility Analysis

The short answer is yes, onions, figs, and nasturtiums can be planted together, but with some considerations. While they have different growing requirements, they can complement each other when managed properly. Onions are known for their pest-repellent properties, which can benefit figs by deterring unwanted insects. Nasturtiums can attract pollinators and serve as a trap crop for aphids, benefiting both onions and figs. However, differences in water and soil needs must be addressed to ensure all plants thrive.

Key Factors

• Growth Requirements: Onions prefer full sun and well-drained soil, figs need ample sunlight and slightly acidic to neutral soil, while nasturtiums thrive in poorer soils and can tolerate partial shade.
• Pest Control: Onions repel many pests, nasturtiums attract beneficial insects and can serve as a sacrificial plant for pests.
• Nutrient Needs and Spacing: Proper spacing ensures that each plant receives adequate nutrients and sunlight.
