Description
Rhizopon Chryzotop Green 25g is a professional-grade rooting powder containing 0.25% indole-3-butyric acid (IBA) as the active ingredient, formulated for the propagation of softwood and semi-hardwood cuttings. We have been recommending Rhizopon to UK horticulturists and growers since 2017 as the professional-standard rooting hormone powder used by nurseries, plant propagators, and serious home growers who want reliable, fast rooting of cuttings across a wide range of plant species.
How Rhizopon Chryzotop Green Works to Stimulate Rooting
Indole-3-butyric acid (IBA) is the most widely researched and consistently effective auxin for stimulating adventitious root formation in plant cuttings. When applied to the cut base of a stem, IBA triggers the hormonal cascade that initiates root primordium formation — the cluster of cells that develops into the new root system. Chryzotop Green at 0.25% IBA concentration is matched to the rooting requirements of a broad range of softwood and semi-hardwood cuttings including herbs, houseplants, fruit bushes, ornamental shrubs, and many vegetable species. The powder formulation has several advantages over liquid and gel alternatives: it provides a dry, adherent coating that stays on the cut surface during insertion without washing off, it has a long shelf life when stored correctly, and it is easy to apply consistently every time. The talc carrier in the powder absorbs cut-surface moisture and ensures good contact between the IBA and the wound tissue where root initiation occurs.
How to Use Rhizopon Chryzotop Green for Propagation
Take cuttings at 7–15cm length from healthy, disease-free parent material using a sharp, sterile blade. Make the basal cut just below a node at 45 degrees. Pour a small amount of Chryzotop Green onto a clean surface or into a small container — never dip directly into the main pot. Dip the moist cut end approximately 1cm into the powder, tap gently to remove excess, then immediately insert into moist propagation medium. Maintain humidity above 75% and temperature at 20–25°C. Rooting typically occurs within 2–4 weeks depending on species. Store Chryzotop Green in a cool, dark, dry location and check the expiry date before use to ensure hormone potency.
Combine Rhizopon Chryzotop Green with a quality propagator, heat mat, and starter nutrient such as Formulex for a professional propagation setup with consistently high success rates.
