This study was conducted in Çanakkale province (North-West Anatolia) to find the optimal auxin dosages (IBA 2000 ppm and NAA 1000 ppm) and rooting medium (soil, peat, and cocopeat) for cutting propagation of lavender, which has great industrial and commercial value. Hemus, Sevtopolis and Drujba varieties belonging to the Lavandula angustifolia species and Super A variety belonging to the Lavandula intermedium species were used as study materials. The experiment was set up with 3 replications according to the split-plot trial design divided into random plots. As a result, the Super A variety of Lavandula intermedium species cultivated in cocopeat medium following IBA 2000 ppm administration had the highest rooting rate (88.33%) and rooting status (17.67 units). The Sevtopolis variety of the Lavandula angustifolia species produced the highest root number (15.33 pieces), root length (9.88 cm), shoot number (20.93 pieces), and shoot length (15.35 cm) values when grown in cocopeat medium with IBA 2000 ppm application. According to these results, cocopeat medium and IBA 2000 ppm auxin application came to the fore in the propagation of lavender by cuttings.
