Anthurium plants, also known as flamingo flowers for their brightly colored blooms, are widely available as flowering houseplants throughout the year. Native to the tropical Americas, the plants cannot tolerate cold temperatures, but thrive under typical household conditions. Anthurium flowers produce blooms in shades of white, yellow, red and pink nearly year-round with proper care. The plants also tolerate relatively low light, though too little light will stunt blooming. Finding a balance is crucial to the survival of anthurium plants, but aside from this, they require only minimal care to grow and flower indoors.
Keep anthurium plants in a location that receives bright, indirect light throughout the day, such as an east- or north-facing window. Maintain a constant temperature of 70 to 80 degrees Fahrenheit for optimal growth. Typical household temperatures are usually sufficient, though cooler temperatures will stunt growth and flowering.
Mist the plants twice per day, once during the early morning and again at mid-day, to eliminate dust and temporarily increase the relative humidity of the air surrounding the plant. Use a spray bottle filled with room temperature water to prevent shocking the plant.
Water anthurium plants once every 10 days, allowing the soil to dry out slightly between applications. Add water to the container until it begins to seep from the drainage holes on the bottom, and then drain away any excess water to prevent rotting.
Feed once every two months using a 5-10-5 NPK fertilizer to provide adequate nutrients for flowering and foliage development. Water lightly before and after feeding to minimize the risk of root injury. Check the manufacturer's directions for proper dosage information.
Remove all dried and dead foliage and flowers whenever possible to increase anthurium plant's appearance and health. Pinch off the old growth near its point of origin to reduce damage to the plant and promote regrowth.
Repot anthurium plants once every two to three years, or whenever the plant appears crowded in its current pot. Increase the size of the new container by 3 to 4 inches and provide a fresh, moist potting soil to ease the stress on the plant.
