Stim-Root is Plant Products proprietary rooting hormone. Used and trusted by generations of growers, Stim-Root has been relied upon to help cuttings establish quickly. Indole-3-butyric acid or IBA, is the active ingredient that encourages the cutting to develop roots when it otherwise would not.
Plant Products offers Stim-Root as a powder in 3 different concentrations, and as a liquid solution in 3 different concentrations. Simply dip the lower ½” of the cutting, tap to remove excess powder or liquid and stick the cutting.
0.8% IBA is ideal for hardwood plants and for rooting difficult to
propagate plants such as evergreens and dormant leafless cuttings.
