Rooting Hormone: Boost Your Propagation Success Rate

What Is Rooting Hormone?

A powder, gel, or liquid containing synthetic auxins (like IBA or NAA) that stimulate root formation on cuttings. Many formulations also include a fungicide to prevent rot at the cut site.

How to Use It Correctly

1. Take a clean cutting.
2. Dip the cut end in water (helps powder adhere).
3. Dip into rooting hormone—just coat the cut surface.
4. Tap off excess. Too much hormone inhibits rooting.
5. Plant immediately in moist rooting medium.

Why It Matters

While some plants root easily without it (pothos, spider plants), hormone dramatically improves success for woody or difficult species (ficus, dracaena, citrus). It’s inexpensive insurance for your propagation efforts.

Choosing a Product

Look for a product with 0.1–0.8% IBA and a fungicide. Powders are easiest for beginners; gels stay on better. Store in a cool, dark place and replace annually—potency fades.
