Can You Plant Onions, Garlic, and Oranges Together?

Companion planting is a popular gardening technique that involves growing different plants together to maximize their growth potential, deter pests, and enhance flavors. Many gardeners wonder if onions, garlic, and oranges can be planted together. In this article, we will explore their compatibility, growing requirements, benefits, challenges, and best practices for planting these crops together.

Compatibility Analysis

The short answer is NO, onions, garlic, and oranges are not ideal companions for planting together. While onions and garlic are compatible with each other, they have different requirements compared to oranges.

Onions and garlic, both members of the allium family, thrive in similar conditions and can benefit from each other’s pest-repelling properties. However, oranges, being citrus trees, require different growing conditions. Key factors affecting their compatibility include:

• Growth Requirements: Onions and garlic prefer cooler climates and well-drained soil, while oranges require warm temperatures and well-drained, slightly acidic soil.
• Pest Control: Onions and garlic can repel certain pests, but oranges have specific pest issues that alliums do not address.
• Nutrient Needs: Oranges need more nutrients and space to grow than onions and garlic.
• Spacing: Oranges, being trees, require significantly more space and have a different growth habit compared to the bulbous onions and garlic.
