When growing anthurium indoors, place the plant 5 to 8 feet from an eastern- or southern-facing window to provide the plant with bright, diffused light. Choose a well-draining growing medium - such as peat moss, pearlite and pine bark in equal parts - and place a layer of pebbles in the bottom of the container to encourage proper drainage. Mist the plant daily, water every three to four days, and repot the plant if it dries quickly after watering.
Western-facing windows are also suitable for anthurium if you cover the window in the late afternoon to prevent exposure to direct sunlight. Move the plant to a brighter area if flower production slows, and move the plant away from the window if the leaves become discolored.
Anthurium thrives in temperatures that range from 60 to 85 F but can withstand temperatures up to 90 F during the day. Do not place the plant near vents, radiators or drafty areas, and avoid exposing the plant to freezing temperatures.
Apply a diluted, low-nitrogen fertilizer every six to 12 days or during every third to fourth watering. When repotting anthurium, choose a container that is one size larger than the current container, and use a pot with drainage holes to prevent root rot.
