Can You Plant Onions, Peaches, and Nasturtiums Together?

Companion planting is a gardening technique that maximizes growth, health, and productivity by strategically pairing plants. Gardeners often wonder about the compatibility of different plants, such as onions, peaches, and nasturtiums. This article will explore whether these three can thrive together, considering their growth needs and benefits.

Compatibility Analysis

Yes, you can plant onions, peaches, and nasturtiums together, but with some considerations. These plants can complement each other, though they have different growth requirements and benefits.

• Onions are excellent companion plants due to their pest-repellent properties, deterring pests like aphids and beetles.
• Peaches benefit from pest control but require more space and specific soil conditions.
• Nasturtiums attract beneficial insects and repel pests, making them a natural partner in the garden.

Key Factors

• Growth Requirements: Onions and nasturtiums have similar sunlight and soil preferences, while peaches need more space and a slightly different soil pH.
• Pest Control: Onions and nasturtiums provide natural pest deterrents, which benefit peaches.
• Nutrient Needs: Onions and peaches may compete for nutrients, requiring careful soil management.
• Spacing: Peaches need more space, so plant onions and nasturtiums at the tree’s periphery.
