The leaves of your anthurium (Anthurium andraeanum) are starting to grow in a helter-skelter pattern, and its flowers have lost their brilliance. Prune anthurium to keep your plant in an organized and healthy shape. There are few maintenance tasks when caring for anthuriums. Water, proper light and an occasional gentle snip are all you need to keep this evergreen houseplant flourishing and producing waxy green leaves and heart-shaped flowers.
The Well-Traveled Anthurium
The tropical rain forests of Colombia, Guatemala and Brazil's Amazon region are the native habitats of the anthurium, where they attach themselves to trees. These epiphytes, or air plants, produce few roots and do not draw nutrients from the trees but from air, water and bird droppings. Replicating a tropical environment inside your home (without the bird droppings) keeps the plant growing and producing until it reaches over 20 inches in height and flourishes for at least five years.
Selecting Your Anthurium
Choose carefully when selecting which anthurium to bring into your home. A garden center's display can be hypnotizing with all the green leaves surrounding brilliantly red flowers, but further investigation is necessary before going to the cash register. The leaves should be waxy, shiny and completely green. Discolored leaves indicate too little or too much water.
The red-hued flowers, known as spathes, and the creamy yellow stalk protruding from the center of the spathe, known as a spadix, will not be discolored if the plant is healthy. The foliage should not be damaged. The plant should look free of pests, and the leaves should have no spots. An overabundance of leaves indicates that the garden center hasn't pruned or maintained the anthurium.
Anthurium’s Perfect Environment
Keeping the indoor temperature higher than 60 degrees Fahrenheit and providing ample sun and warmth year-round promotes anthurium growth and health. Keep the soil moist but not wet and cover the surface soil with moss to keep in moisture. Humidity is the lifeblood of anthurium, as the plant feeds on the water in the air. Mist the plant frequently. Consider repotting every two years in early spring to midsummer to rid the soil of minerals that were deposited by watering and to revitalize the plant.
How to Prune Anthurium
Discolored leaves and/or flowers must be pruned away from your plant. An overabundance of leaves chokes the plant. Use your hands, sterilized secateurs or gardening shears to trim away the nearly dead leaves, keeping in mind the shape of your plant. Cut off faded flowers all the way down to the base, as new flowers do not grow from the original stem. When trimming the leaves of an anthurium, don't be too aggressive. Leave at least four leaves on the plant.
If the plant is getting leggy, consider repotting it. Water before repotting to feed the roots and avoid transplant shock. Cover the bald main stem with soil to encourage new root growth and give vitality to the plant. Remove the stipules, which are those dry, brown, barklike growths that protected the leaves when they were new and no longer serve a purpose.
