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/m3). 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.
