No, onion is not a good rooting hormone. While onions are known for their antimicrobial properties and contain some compounds that may promote growth, they lack the specific hormones that are essential for root development.
Rooting Hormones and Their Functions
Rooting hormones, also known as auxins, are plant hormones that stimulate root growth. These hormones, like indole-3-butyric acid (IBA) and naphthalene acetic acid (NAA), are specifically formulated to encourage root formation in cuttings and seedlings.
Why Onion Doesn't Work as a Rooting Hormone
Onions contain sulfur compounds that can inhibit root growth. These compounds are beneficial in other ways, such as protecting the plant from pests and diseases, but they are not effective as rooting hormones.
Alternatives to Onion for Rooting
Instead of using onion, consider using commercially available rooting hormones. These products are specifically designed to promote root growth and are readily available at garden centers and online retailers.
