Hormodin 3 Rooting Hormone Powder - 0.8% IBA - 8oz

Maximum-Strength IBA Rooting Powder, 0.8%

Dormant leafless cuttings and the hardest-to-root evergreen and ornamental varieties often fail to root even with a standard hormone dip, because the cutting simply needs a stronger initiating dose than easier stock does. Hormodin 3 is formulated at 0.8% IBA, the highest concentration in the Hormodin line, specifically for that difficult-to-root category.

This 8oz container is sized for propagators working with difficult-to-root evergreens, ornamentals, and dormant leafless cuttings rather than general-purpose softwood or semi-hardwood propagation.

Key Features & Benefits

• 0.8% IBA concentration — the strongest formula in the Hormodin line, built for the hardest-to-root plant material.
• Formulated for difficult-to-root evergreens and dormant leafless cuttings — targets plant material that a lighter hormone dose often fails to root.
• Dip-and-stick application — no mixing, soaking, or pre-treatment step before sticking the cutting into the rooting medium.
• Reduces propagation bench time and plant loss — matching maximum-strength hormone to the hardest cuttings improves take rate on stock that would otherwise fail.

Who Should Use This

This fits growers propagating difficult-to-root evergreens, woody ornamentals, and dormant leafless cuttings that haven't rooted reliably with a lighter hormone concentration.

Frequently Asked Questions

How do I use Hormodin 3

Dip the cut end of the cutting into the powder, tap off any excess, and stick it into your rooting medium, the same dip-and-stick method used across the Hormodin line. No mixing or pre-soaking is required.

What makes a cutting difficult enough to need Hormodin 3

Difficult-to-root evergreens, many woody ornamentals, and dormant leafless cuttings often fail to initiate roots with a lighter hormone dose, which is why Hormodin 3 is formulated at 0.8% IBA, the highest concentration in the line. If Hormodin 1 or 2 hasn't produced a reliable take rate on a given variety, the stronger formula is the next step.

What is the re-entry interval for Hormodin 3

The labeled REI is 0 hours, meaning there's no mandatory wait before re-entering a treated propagation area. Review the full label for complete application and handling directions.

Is Hormodin 3 too strong for easy-to-root cuttings

It can be more concentration than soft herbaceous or easy-rooting cuttings need, which is why OHP offers Hormodin 1 and 2 at lighter IBA doses for that material. Matching concentration to how hard a specific cutting roots is generally the better approach than defaulting to the strongest formula across the board.
