Anthurium is genus of flowering plant with over 800 different species spread over Central America to South America. Anthurium plants are native to tropical regions from Mexico, the West Indies and Argentina. In most regions of the U.S. anthuriums must be grown indoors as they are only hardy to U.S. Department of Agriculture hardiness zones 10 to 11 in most cases.
Since anthuriums are tropical plants, they need to be kept in constantly warm conditions. Most anthuriums grow best with a day time temperature between 78 to 90 degrees Fahrenheit and a night time temperature from 70 to 75 degrees Fahrenheit. Keep the humidity around the anthuriums high by spraying them with water several times a day.
Since it is too cold to grow anthuriums outdoors in most of the U.S., they are usually used as houseplants. Anthuriums need a well-drained pot in which to grow. It is best to fill the pot with your own mixture of one part peat moss, one part pine bark and one part perlite. Place the anthuriums in indirect sunlight but make sure they get about 500 foot-candles of light a day.
Anthurium has a moderate drought tolerance and can handle having its roots dry for short periods of time. It is best to water the anthuriums so the water seeps out of the bottom of the container, then allow the growing medium to dry out slightly, about 3 to 4 inches deep, before you water again.
Anthurium plants need light fertilization from time to time. Add a slow release 3-1-2 fertilizer to your anthurium plant every few months, but dilute it by one-fourth to ensure you don't over fertilize.
