Scale insects are somewhat more difficult to get rid of and will require an organic pesticide. You can water two or three times a week during hotter months but thats not advised during colder times. If the leaves of Anthurium appeared brown spots, they began to wilt, turn yellow and dry, most likely it is not properly cared for. A drop of water becomes a lens, concentrating the light, as a result, the leaves appear burned in the form of brown spots. Field sanitation, which involves removal of leaves showing early infections and elimination of systemically infected plants, was the principal method of reducing anthurium blight in early years (42). Norman, D., and Alvarez, A. Spider mites are common to indoor anthuriums grown in too wet conditions. Anthurium leaves are pretty with their bright green hue and glossy shine, but it's the flowers that really earn this tropical houseplant rave reviews.
