The study was conducted in Bsheli and Helbako in Lattakia governorate, Syria to evaluate the effect of location and treatment with 1000 ppm concentration of indole butyric acid and aloe vera gel on the rooting of Rosa canina cuttings. The design was completely randomized in this factorial experiment. The results showed that the rooting percentage (52%) in the Bsheli was superior to Helbako (47%) while average root length in Helbako at 5.85 cm exceeded that of the Bsheli’s 4.40 cm. At the same time, location had no significant effect on the average number of roots and buds or on survival percentage. The highest rooting rate (86%) was achieved for Bsheli cuttings treated with 1000 ppm indole butyric acid concentrations for ten seconds combined with aloe vera gel, followed by those treated similarly from Helbako (79%). The lowest rates were obtained from the untreated cuttings from Bsheli and Helbako at 14.97% and 11.73%, respectively. The interaction between location and experimental treatments significantly affected average rooting percentage, number of roots, root length, and number of buds on the cuttings. The findings recommend using 1000 ppm indole butyric acid concentrations together with aloe vera gel to obtain the best rooting and highest survival percentage for the rose hip cuttings
