Stim-Root 5000 1L
Liquid Stim-Root’s effectiveness comes from higher concentrations of Indole-3-butyric acid (IBA), more uniform application to cuttings, and better penetration into woody cuttings. Better rooting than with powders, occurs with many hard-to-root species.
The carrier used for Liquid Stim-Root has greater potential to burn compared to Stim-Root Powder. A trial on a small number of cuttings at different concentrations is always recommended.
