Yields of Rose (Rosa)and Hibiscus(Hibiscus rosasinenis) flowering plants were made by irrigated with distillery spent wash of different concentrations. The spent wash i.e., primary treated spent wash (PTSW), 1:1, 1:2, and 1:3 spent wash were analyzed for their plant nutrients such as nitrogen, phosphorous, potassium and other physical and chemical characteristics. Experimental soil was tested for its chemical and physical parameters. Rose and Hibiscus sets were planted in different pots (50 cm ht and 30 cm dia) and irrigated with raw water (RW), 1:1, 1:2 and 1:3 spent wash. The nature of yields of flowers was studied at their maturity. It was found that the yields of both flowers plants was very good (100%) in 1:3 SW irrigation, while very poor (25%) in 1:1 SW, moderate (80%) in 1:2 SW and 95% in RW irrigation growth. Soil wastested after harvest of flowers found no adverse effect on soil characteristics. This concludes that the diluted spent wash serves as an eco-friendly in irrigation medium
