Roots begin to weaken, and leaves turn pale and wilt.Ī saline soil does not support plant growth, and unless the mixture is rinsed of excess salts and nitrogenous compounds, your Anthurium plant will not sustain for long. Similarly, a highly saline soil mixture with a significant accumulation of salts prevents adequate water uptake by roots. However, this can prove to be detrimental to your plant’s health.įertilizers contain high concentrations of chemical compounds, which can severely disrupt the soil mixture’s pH, making it too acidic or alkaline.Īs a result, the enzyme activity in plant cells takes a toll and leaves begin to brown. Outdoor and Indoor Gardeners are often tempted to increase the fertilizer dosage to promote faster growth and grow bigger plants. 2.Overuse of Fertilizer or Saline SoilĪnthuriums are beautiful plants with bright blossoms and large leaves. If the plant is persistently exposed to direct sunlight, brown leaves shrivel up and die. Intense sunlight exposure scorches the leaves, and over time the tips and edges turn brown. Too little sunlight can hinder the plant’s healthy growth, lead to a slower rate of photosynthesis, and consequently cause very few new leaves and blossoms to sprout.Īt the same time, since these plants are ideally grown in the shade, placing them under the open sky beneath the glaring sun or directly in front of a south-facing window is even more harmful. 6 Factors That Lead to Brown Leaves on Anthurium 1.Intense Sunlight ExposureĪnthurium plants thrive in generous amounts of indirect sunlight. These include measures like placing your plant in a shaded area and maintaining proper plant hygiene. Although brown leaves are not a highly concerning issue if addressed at an early stage, you can save your plant from shedding all leaves and dying. Other causes include pathogenic infections and attacks from pests, like spider mites. Some of the reasons include prolonged exposure to harsh sunlight and excessive use of fertilizers. There are a series of reasons why your Anthurium plant may have brown leaves.
