Water your Anthurium when the top 50% of the soil is dry. Water until liquid flows through the drainage hole at the bottom of the pot and discard any water that has accumulated in the saucer. Overwatering causes yellow leaf tips and underwatering causes brown leaf tips.
Care of anthurium plants does not require too much fertilizer. The plant only needs to be fertilized with a one-quarter strength fertilizer once every three to four months. To get the best blooms, use a fertilizer that has a higher phosphorus number (the middle number). Proper care for anthuriums is not hard
Flowering Anthurium needs bright, indirect light (direct sunlight will scorch the leaves and flowers!). Low light will slow growth, dull the color, and produce fewer, smaller “flowers.” Place your anthuriums in a setting where they will receive at least 6 hours of bright indirect sunlight each day
It will do best with warm temperatures of 75º to 85ºF during the daytime, and 70° to 75°F at night, but temperatures as low as 45°F and as high as 90°F can be tolerated. Anthuriums need humidity to be at 50 percent or more, much higher than in the average home interior.
How to repot anthuriums. Carefully remove it from its current pot, trimming any brown leaves or wilted flowers. Then place it into a slightly larger pot (about 1-2 inches larger in diameter) and fill it with a light and aerated soil blend, such as a blend that is 50% peat moss and 50% coconut fiber.
