This study was conducted to assess the influence of gibberellic acid (GA₃) and arbuscular mycorrhizal fungi (AMF) on the flowering and quality of <i>Zantedeschia albomaculata</i> (Hook.) Baill ‘Albomaculata’ plants. Before planting, the rhizomes were soaked in water or an aqueous solution of GA₃ at a concentration of 150 mg dm⁻³ for 30 min. A mixture of AMF was applied to the rhizomes a week after planting. The AMF treatment increased the yield of inflorescences of the ‘Albomaculata’ cultivar by 100%. AMF and GA₃ had a favourable effect on the quality of inflorescences, expressed by the length of peduncles, whereas AMF individually positively affected the length of the spathes. AMF and GA₃ had no effect on the level of macroelements in calla lily leaves, with the exception of calcium (Ca). The leaves of mycorrhized plants had a high content of sodium (Na) and micronutrients, except for iron (Fe). The results of the study showed that GA₃ could be replaced by mycorrhizal inoculation when applied to Zantedeschia plants.
