To care for a Vriesea 'Splenriet' bromeliad, provide bright, indirect light and maintain high humidity by misting or using a humidifier. Water the central cup with filtered water, emptying and refilling it every couple of weeks to prevent stagnation, and keep the soil lightly moist. Fertilize monthly with a half-strength liquid fertilizer during the growing season, and wait to remove pups until they are at least one-third the size of the mother plant.
