( Fig. 1A ). Moderate symptoms included greater discoloration and more prominent upward leaf curling as well as necrosis of the leaf tips. At advanced stages of the deficiency, whole leaves and the apical meristem became necrotic ( Fig. 1B ). Plants

, deficiencies that might merely cause twig dieback in dicots can be fatal in palms, which have only a single apical meristem and no lateral meristems. Thus, proper fertilization for palms is important for palm health and survival, as well as for aesthetics. As
