Many gardeners wonder whether asparagus and onions, two popular vegetables, can be planted together. This blog post will delve into the compatibility of these two vegetables, providing a comprehensive guide to their companion planting.
Benefits of Companion Planting Asparagus and Onions
When planted together, asparagus and onions can offer several benefits:
- Pest control: Onions release a pungent odor that repels insects, such as aphids and spider mites, which can damage asparagus plants.
