Experiment was conducted to develop plant propagation protocol via cutting in Euphorbia milii with the basic objective to enhance branching to obtain more number of cuttings for rooting and to standardize rooting treatment and rooting media. Pinching and foliar application of plant growth retardants significantly influenced vegetative growth and branching pattern of Euphorbia milii. Reduced plant height with thickest stem and maximum branches with more number of leaves was observed in pinched plants treated with Alar at 300 mg/l (P1R6) in var. ‘Pink Bold Beauty’. Further, Maximum number of cuttings (7.19, 7.47) for propagation was obtained from pinched plants with foliar application of Alar at 300 mg/l during the experiment. Treatment of IBA (0, 250, 500, 750 mg/l) and rooting media (sand, cocopeat and cocopeat + banana pseudo stem fibers) significantly influenced rooting in cuttings of Euphorbia milii and their shoot growth. Cuttings treated with IBA (750 mg/l) as quick deep method and stumped in cocopeat media (M2I4) showed early sprouting with highest sprouting percentage. Cuttings of Euphorbia planted in cocopeat media after treatment of 750 mg/l IBA (M2I4) showed higher number of roots per cutting (14.37, 15.71), maximum root length (7.98, 9.27) and higher survival percentage (91.52, 89.03 %) in var. ‘Pink Bold Beauty’ during the consecutive years of study.
