The invention provides a cutting propagation method of pelargonium graveolens and belongs to the technical field of plant propagation. The cutting propagation method includes following steps: 1), building a pelargonium graveolens scion female parent nursery in a greenhouse; 2), from middle March to middle October, cutting one-year-old semi-carnificated twigs from the female parent nursery, and disinfecting to obtain cutting wood; 3), soaking the cutting wood obtained in the step 2) in a rooting agent solution of 500-750ppm for 5-10s, and performing cottage; 4), immediately after cottage in thestep 3) is completed, spraying water, maintaining 32-48d, then hardening seedlings. By utilizing the method, if one female parent plant is cut for 3-4 times and 60-80 scions are obtained each time, seedling survival rate is higher than 90%, and propagation coefficient is about 162-288. The method is simple in operation, low in cost, high in propagation speed and stable in hereditary character ofseedlings, and only 39-58 days are needed from cutting to formation of commercial seedlings.
