A tropical plant native to Hawaii, anthurium is a low maintenance houseplant that provides unusual rubbery flowers and elongated heart-shaped leaves. The flowers resemble calla lilies, with white or yellow stamens and waxy, thick shell-shaped petals. Anthurium flowers year round. The plant dislikes cold temperature of 40 F, preferring a warm growing environment of 78 to 90 F. Keep your anthurium in a warm room and free from drafts to prevent damaging the plant with cold.
Place your anthurium in a location where it receives lots of indirect sunlight. The plant leaves can bleach if given too much direct sun. If given too little light, the plants will produce few to no flowers and the leaves may become distorted.
Water your anthurium whenever the soil becomes dry and crumbly. Stick a finger into the soil to make sure the lower levels of soil are also dry: If the soil feels cool and moist, withhold watering until it feels dry. Add water until the soil becomes saturated and water floods out the drainage holes in the plant's container. Then allow the soil to dry out again. If the leaves turn yellow, you may be watering too often.
Rotate your plant in the window twice a week, turning it one-quarter of the way around each time. This will prevent any one side from receiving too much light exposure.
Fertilize your anthurium using a 3-1-2 fertilizer. Hawaii Tropicals recommends diluting the fertilizer to 1/4 of the recommended dose range by mixing in water, then apply the solution to your plant to fertilize. Apply fertilizer three to four times a year.
Repot your anthurium when its roots fill the pot and begin growing out of drainage holes. Choose a container one size up from the one you are using. Combine equal parts peat moss, pine bark and perlite to create a potting mix. Fill your new container 1/3-full with this mix. Pull your anthurium from its container and break apart the roots with your fingers. Place the plant in the new container and cover the roots with potting mix. Fill the container within 1-inch of the top. Water the plant until water runs out the drainage holes.
