In the paper, we present vegetative propagation opportunities by cuttings in five species of Pelargonium in a private area in Giarmata, Timiş County, Romania. We monitored four species of Pelargonium rooting in various culture substrates, and as a control variant, we used sand. Research took place over a period of two years, 2019 and 2020. The rooting of the cuttings was made in the first half of July of each year, and the verification of the rooting was made in the second half of August. The plants were laid in boxes and left to hung in warm greenhouses and, in March, the rooted cuts were planted in a mixture of barbel and sand, in pots having a diameter of 10 cm. From each species, we took 20 pots and monitored the number of rooted cuttings from each species and substrate, we calculated the average and the relative value and the difference to the control. Data were processed by statistically calculus using variance analysis. Following the results, for production, we recommend the multiplication by cuttings of the zonal Pelargonium species, having as main stage attaching the cuttings in the perlite and sand + perlite substrates, in which the percentage of rooting compared to the control sand was the highest. For Pelargonium grandiflorum, we recommend multiplication by cuttings in peat and pearl + peat substrates, where higher rooting over the control was recorded. For Pelargonium peltatum, we recommend multiplication through cuttings in the peat substrate. In the species Pelargonium odoratissimum, we recommend multiplication with cuttings planted in the sand substrate, where the best results for Pelargonium production were obtained.
