This study was conducted to determine the effect of ZPT and Covering on the Growth of Indian Waru Stem Cuttings (Hibbiscus Tiliaceus L), conducted in Senenan Village, Tahunan District, Jepara Regency from July to September 2023. The study used a factorial experiment with a basic pattern of Completely Randomized Block Design (CRBD) consisting of two factors and three replications. The first factor is zpt (Z), consisting of 3 levels, namely Z0 (without zpt), Z1 (rapid root zpt), Z2 (root up zpt). The second factor is cover (S), consisting of 2 levels, namely S0 (without cover) and S1 (covered). The observed parameters included the percentage of cutting growth, time of shoot emergence, length and number of roots, length and number of shoots, fresh and dry weight of plants. The final results showed that the treatment of zpt was significantly different in the percentage of growth, time of shoot emergence, shoot length at 8 WAP, and the number of shoots at 10 WAP. The treatment of covering significantly differed in the time of shoot emergence, shoot length at 8 WAP, and the number of shoots at the ages of 4, 8, and 10 WAP. There was an interaction between the provision of PGR and covering on the percentage of shoot growth, time of shoot emergence, number of roots, shoot length at 8 WAP, and number of shoots at 8 and 10 WAP.
