Abstract Stimulating root formation is the key to successful cutting propagation. Natural root stimulators are eco-friendly, biodegradable and sustainable tools that prevent the environment from pollution. Horticulturists have given the role of sol-vents in natural extracts little attention. Therefore, the aim of this study was to study the effect of three extract solutions (aqueous, vinegary and ethanol) for ten natural extracts (humic, licorice roots, ginger roots, cinnamon bark, garlic bulbs, bread yeast, moringa leaves, willow leaves, willow shoots and control at a concentration of 20% on rooting of Coratina hardwood olive cuttings. Regarding the effect of solvent on rooting performance of Coratina olive cuttings, both ethanol and vinegar as a sol-vent improved the efficiency of the natural extract in rooting behavior compared to the water as solvent. Regarding the effect of the natural extracts, ginger extracts generally recorded the highest root charcgters compared to the other natural ex-tracts. As for the interaction effect, licorice vinegar extract recorded the highest root-ing percent (25%, 32.77%) followed by both humic ethanolic (27.07%, 24.67%) and vinegary (25.03%, 19.67%) extract then ginger vinegar extract (20.83%, 18%) for both seasons, respectively. According to organic farm regulation, ginger vinegar extract can be recommended followed by licorice vinegar extract.
