Short answer
Brown spots on a Golden Pothos are most commonly caused by inconsistent watering, which leads to localized tissue death at the leaf margins or tips. To resolve this, establish a consistent routine where you allow the top two inches of soil to dry out completely before watering thoroughly.
Brown spots on Epipremnum aureum usually appear as crisp, dry, or dark brown patches on the leaf blades, often accompanied by yellow halos. While these spots are rarely fatal, they detract from the vine's aesthetic and serve as a vital signal that your watering or humidity routine requires adjustment.
Pothos are prone to brown spotting when the soil fluctuates too dramatically between bone-dry and saturated. This stress prevents the roots from consistently transporting water to the leaf edges, leading to necrosis.
Check: Check the soil moisture level using your finger or a meter to see if the plant is swinging between extremes.
Fix: Water when the top 50% of the soil is dry, ensuring you saturate the root ball until water drains from the bottom.
While Pothos tolerate average household humidity, indoor air in winter or near vents can become too dry. This causes the delicate leaf tips to desiccate and turn brown.
Check: Look for crisp, brown tips on new growth while the rest of the leaf remains supple and green.
Fix: Place the plant away from AC or heating vents and group it with other plants to create a microclimate.
If the spots are circular with distinct borders or watery centers, it may indicate a fungal infection. This usually happens if leaves remain wet after misting or poor air circulation.
Check: Observe if the spots grow rapidly or have a fuzzy texture under magnification.
Fix: Remove infected leaves immediately, improve air circulation, and avoid misting the foliage directly.
When to worry
You should take urgent action if the spots are spreading rapidly or if the stems at the base of the plant become mushy, as this indicates root rot which can kill the entire vine.

Diagnose my Golden PothosYes, you can trim away the brown parts with clean, sharp scissors for aesthetic reasons. Avoid cutting into the healthy green tissue, as this creates a new wound for potential infection.
Direct sunlight can cause 'sunburn' which appears as bleached or crispy brown patches, typically on the leaves facing the window. If you see this, move the plant to a spot with bright, indirect light.
Over-fertilizing can lead to salt buildup in the soil, which burns the root tips and manifests as brown leaf edges. If you have been fertilizing weekly, flush the soil with water to leach out excess salts.
