Three factorial experiments with various combinations of N, P or K were conducted over 3 years with Schlumbergera truncata (Haw.) Moran. Blooming was influenced by fertilization. Number of blooms was reduced by both low and high fertilization. Nitrogen appeared to be the most influential element, with high levels decreasing time to bloom and number of blooms. Potassium had no effect, and an increase in phosphorus decreased time to bloom and number of blooms.
