Plant-Prod Stim-Root 2500 Liquid is a liquid rooting hormone for plant cuttings, designed to support fast, uniform root start during propagation. This rooting hormone is also a plant propagation hormone for growers who want reliable rooting performance from a clean, easy-to-handle liquid format.
Stim-Root 2500 Liquid is based on indole-3-butyric acid (IBA), a proven rooting hormone ingredient used to encourage new root formation in cuttings. As a liquid rooting hormone, it’s valued for more uniform application to cuttings, helping deliver consistent coverage from cutting to cutting. That consistency supports repeatable results in busy propagation areas where uniform starts matter.
Because liquid Stim-Root is designed for better penetration into woody cuttings, it’s a practical option when you’re working with firmer stems that can be slower to establish. It’s also positioned to stimulate rapid root growth while increasing root uniformity, helping you bring batches forward with a steadier, more even root profile. For growers tracking outcomes across trays, that emphasis on root uniformity and rooting percentage of cuttings is a meaningful advantage in day-to-day propagation work.
Plant-Prod also highlights that better rooting than powders can occur with many hard-to-root species, making this liquid rooting hormone a strong choice when powder-style rooting hormones feel inconsistent on tougher material. The result is a propagation tool that stays focused on what matters most: a dependable rooting response, improved early establishment, and more predictable propagation results across a range of cutting types.
Plant-Prod Stim-Root 2500 Liquid is a good fit for growers, nurseries, and hobby propagators who want a liquid rooting hormone that supports uniform cuttings, faster establishment, and consistent rooting outcomes in propagation workflows.
Indole Butyric Acid (IBA) is important because it helps cuttings form new roots faster and more reliably, which reduces wilting, stalling, and failure during propagation. It’s unique because it works as a targeted rooting signal that specifically supports root initiation instead of simply “boosting growth” in general.
