Anthurium plants are very popular house plants that have broad leafs with red, pink or white blossoms. They are very easy to maintain, but will have some problems with diseases. Here is a quick guide to help you determine which disease is invading your plant.
This is the most devastating disease to anthuriums. Most common in areas of high rain, it is also called spadix rot, or black nose. It causes severe damage to the spadix, and the flowers are no longer viable.
During the rainy season, if you notice that the plant is beginning to droop and the leaves are losing their color quickly, the plant is being attacked at the root by a fungal bacteria. Root rot will cause severe damage if not treated quickly.
When gray mold begins to set in, it will appear as a brown discoloration of the leaves and stems. After some time, it will begin to take on a gray discoloration and the affected areas will begin to whither and turn in. Remove the affected area, and watch for any signs of the disease returning.
Much like the common cold, anthuriums can catch virally transmitted diseases. Check for signs of mosaic colors and malformation of the leaves. This can be transmitted by grafting a piece of another plant in with another stem.
