Water: The soil should be kept slightly moist all time and never allowed to dry out completely. Use mineral water. Allow the top of the soil to dry out to the touch before watering again.
Nutrients/Fertilizer: Use a fertilizer high in phosphorus, and dilute it to 5% pf soltion to feed the plants every two weeks or so. Any other balanced fertilizer will work also.
Light: Flowering anthurium needs bright, indirect light (direct sunlight will scorch the leaves and flowers). Low light will slow growth and produce fewer, smaller flowers.
