Abstract
Spathiphyllum ‘Petite’ and Dieffenbachia ‘Camille’, two popular foliage plants sensitive to excess salts, were grown using 9 levels of water-soluble fertilizer in a 3-1-2 ratio of N-P2O5-K2O. The range for maximum growth occurred at 100–200 ppm (mg/1) N for Spathiphyllum and 200–400 ppm (mg/1) N for Dieffenbachia on a constant-feed basis. Spathiphyllum showed more noticeable leaf bum symptoms compared to Dieffenbachia when the concentration of fertilizer in the irrigation water increased above the range that yielded maximum growth.
