摘　　要：Two are the critical factors in the commercial production of ornamental plants： the substrate and the fertilization method, since the ＂sustainable floriculture＂ discourages the use of synthetic chemical fertilizers and peat-based substrates. The aim of this paper was to test a peat/compost based substrate and a guano ＋ mycorrhizal inoculum fertilizer mixture, in order to obtain a sustainable quality yield of geranium plants. Geranium cuttings （Pelargonium zonale cv. real polaris and Pelargonium grandiflorum cv. lotus） were grown for two months in a glasshouse. Peat, in the growing substrate, was replaced with high quality compost （20% and 40% as reduction percentages）. The fertilizer mixture was made up of guano （3 g/L） and mycorrhizal inoculum （7.5 L/m^3）. Plants of Pelargonium cv. Real polaris, grown on a substrate made up of peat and 20% of high quality compost, presented the better trade features, so to satisfy the ＂sustainable floriculture＂ need.
