Neon Pothos (Epipremnum aureum ‘Neon’) is a popular houseplant, known for its bright, chartreuse foliage that can add a vibrant touch to any indoor space. While generally low-maintenance, owners sometimes observe their plant’s distinctive leaves turning brown. Understanding the causes is key to restoring the plant’s health and maintaining its vibrant appearance.
Identifying the Type of Brown Leaves and Their Causes
Crispy, Dry Brown Edges or Tips
Crispy, dry brown edges or tips often indicate insufficient moisture. This commonly results from underwatering, where the plant doesn’t receive enough water to hydrate its extremities. Low humidity in the surrounding environment also contributes, as the plant loses moisture faster than it absorbs it. Too much direct sunlight can also scorch leaf tissue, leading to browning along the margins.
Soft, Mushy Brown Spots or Entire Leaves
Soft, mushy brown spots or entirely brown, soft leaves frequently point to overwatering. Excess soil moisture deprives roots of oxygen, leading to root rot. This prevents the plant from absorbing water and nutrients, causing leaves to become waterlogged and collapse.
Yellowing Leaves with Brown Spots or Patches
Leaves that yellow before developing brown spots or patches can signal various issues. A common cause is nutrient deficiency. Pest infestations also lead to these symptoms, as insects feed on plant sap, causing discoloration and tissue damage. Insufficient light can weaken the plant, making it more susceptible.
Overall Browning and Drooping
Extensive browning and drooping across multiple leaves suggest significant stress. Prolonged underwatering causes severe dehydration, wilting the plant and browning leaves. Extreme temperature fluctuations, like sudden drafts or cold exposure, can shock the plant, resulting in widespread browning. Advanced root rot from severe overwatering also compromises the plant’s ability to sustain itself, leading to general decline.
Solutions for Brown Neon Pothos Leaves
Correcting Watering Issues
To address browning from improper watering, allow the top inch or two of soil to dry completely before watering. Ensure water drains through the pot’s drainage holes. If severely underwatered, a thorough soaking can rehydrate the roots.
Optimizing Light Conditions
Neon Pothos thrives in bright, indirect light, promoting vibrant color and healthy growth. Position your plant several feet from a window receiving direct sunlight to prevent leaf scorching. If light levels are too low, move the plant to a brighter spot or supplement with a grow light.
Increasing Humidity
Increasing humidity helps alleviate dry leaf edges and tips. Misting leaves regularly with room-temperature water provides temporary relief. Placing the pot on a pebble tray filled with water, ensuring the pot doesn’t sit directly in it, creates a humid microclimate. A small room humidifier also raises ambient humidity.
Addressing Nutrient Deficiencies
If nutrient deficiency is suspected, fertilize your Neon Pothos with a balanced liquid houseplant fertilizer during its growing season, typically spring and summer. Dilute the fertilizer to half strength to avoid over-fertilization, which can also cause leaf browning. Fertilize every 2-4 weeks during active growth, and reduce frequency in fall and winter.
Managing Pests
Regularly inspect your Neon Pothos for common houseplant pests like spider mites or mealybugs. If detected, gently wipe them off leaves with a damp cloth or a cotton swab dipped in rubbing alcohol. For persistent infestations, use an insecticidal soap or neem oil spray according to product instructions.
Preventative Care for Healthy Neon Pothos
Consistent care prevents future browning of Neon Pothos leaves. Regularly checking soil moisture and adjusting watering frequency based on environmental conditions helps avoid both overwatering and underwatering. Providing stable temperatures and avoiding sudden drafts supports the plant’s well-being. Ensuring the plant is in an appropriately sized pot with good drainage allows for proper root development and aeration.
