How to Get an Anthurium to Bloom
Vivid blooms and ease of care make anthuriums popular houseplants. However, many people find that they cannot induce their anthurium to bloom every year, which can be disappointing. Fortunately, you can find simple solutions to this problem, since the issue nearly always lies in the location of the plant.
Adjust the watering schedule by season. During the summer, you should water your anthurium every day. The rest of the year, it still needs to be watered three to five times a week. Anthuriums live in rainforest conditions naturally and are accustomed to getting a lot of moisture. This is not a plant that you should wait to water until the soil is dry.
Make sure that you anthurium is getting the right kind of light. Anthuriums like strong but slightly diffused light that makes them feel like they are at home in the treetops of the rainforest. They need to be in sunlight nearly all day, but that sunlight does not have to be direct. Placing them in a window that receives sun should do the trick, or you can place them in a room that remains filled with natural light for most of the day.
Use a sunlamp to supplement your anthurium's light exposure. If you simply cannot get your plant enough natural light, then a sun lamp on a timer should do the trick. Nine hours should be plenty, but do not position the lamp too close to the plant or it will bake. Across the room should be close enough.
Place the anthurium in a tray of pebbles. This will help your plant feel like the air in your home is more humid than it actually is. Spread the pebbles out one-deep in the cookie tray and add about a cup of water. Refresh the water about twice a week as it evaporates.
Mist your anthurium regularly. Keep a spray bottle full of water near your anthurium. When you pass, mist the plant. This will help keep it healthy and happy, which can result in year-round blooms.
