Pothos sunburn usually appears after leaves receive more direct light than they were prepared to tolerate. The damaged area may look pale, bleached, tan, brown, thin, or papery. It is often concentrated on the side of the plant facing a bright window or on leaves that were newly exposed after the plant was moved.
Sunburned tissue will not become healthy green tissue again. Treatment is therefore about stopping further injury and supporting undamaged leaves and new growth. Before moving the plant, confirm that the pattern fits sunburn rather than disease, pests, or root stress.
How to Recognize Pothos Sunburn
A history of changed exposure is one of the strongest clues. Ask whether the plant was recently:
- moved closer to a window;
- placed in direct afternoon sun;
- taken outdoors from an indoor position;
- moved from a shaded shop or greenhouse;
- exposed after a curtain, blind, or neighboring plant was removed.
University of Minnesota Extension specifically warns that pothos can scorch when moved too quickly into stronger spring sunlight. Pale patches or crisp edges following that transition support a light-injury diagnosis.
RHS guidance describes excessive-light injury as brown scorched patches and a washed-out appearance. Damage is often most apparent on directly exposed tissue.
Sunburn or Something Else?
Do not diagnose from brown color alone. Compare the pattern and recent plant history.
Fungal or Bacterial Leaf Spot
Leaf spots may be dark, water-soaked, irregular, or surrounded by discolored tissue. They can arise on leaves that were not facing the light and may continue appearing after exposure is corrected.
The UF/IFAS pothos disease guide describes several diseases with dark lesions, wilting, stem discoloration, or spreading tissue damage. Disease becomes more plausible when damaged areas expand under stable light conditions or several plants develop similar symptoms.
Chemical Injury
Some sprays can bleach or burn pothos foliage, especially when applied during bright or hot conditions. Consider any recent pesticide, cleaning product, foliar feed, or other spray. UF/IFAS reports that certain chemical applications can cause bleaching and tip burn on pothos.
Water or Salt Stress
Underwatering and soluble-salt injury more often affect tips and margins broadly rather than only the window-facing surface. Overwatering can cause yellowing, wilting, or root decline. Check the potting mix and roots instead of increasing water merely because a leaf looks dry.
The PlantGrail guide to Pothos overwatering explains how to evaluate wet mix and root symptoms.
Pests
Inspect both leaf surfaces and stem joints. Fine stippling or webbing suggests mites. Cottony clusters suggest mealybugs, while fixed raised bumps may be scale. Pest damage is not limited to the brightest side of the plant.
What to Do Immediately
Move the plant out of strong direct exposure while keeping it in useful, bright indirect light. Do not move it into a dark corner. Pothos can tolerate lower light, but a severely reduced light level may slow growth and weaken variegation.
Then stabilize the rest of its care:
- Check the potting mix before watering.
- Water thoroughly only when the root zone needs it.
- Allow excess water to drain.
- Keep the plant away from hot glass, heaters, and abrupt drafts.
- Avoid foliar sprays while the diagnosis is being clarified.
- Watch new leaves rather than expecting old damage to reverse.
Penn State Extension recommends moderate to bright light while avoiding direct sun. That is the useful target during recovery.
Should You Remove Burned Leaves?
Keep a damaged leaf when it still has substantial healthy green tissue and is not deteriorating. The remaining tissue can still support the plant.
Remove a leaf when it is almost entirely dead, becomes soft or diseased, or interferes with inspection and airflow. Use clean scissors and avoid removing a large share of the plant at once. Cutting a cosmetic brown patch is optional and does not treat the cause.
Do not apply fertilizer in an attempt to repair burned tissue. Fertilizer cannot reverse dead cells and may add stress if the roots are already compromised.
How to Increase Light Safely
When stronger light is desirable, increase exposure in stages. Begin with filtered light or a position farther from the window. Observe the plant, then make smaller changes rather than one abrupt move.
Window direction is not a complete prescription. Season, latitude, glass, nearby buildings, curtains, and distance from the window all affect exposure. Use the plant’s response:
- Healthy compact growth supports adequate light.
- Stretching and smaller new leaves suggest insufficient light.
- New pale or papery exposure-sided patches indicate too much light or a transition that was too abrupt.
If using a grow light, follow the fixture manufacturer’s placement guidance and begin conservatively.
Preventing Repeat Sunburn
- Acclimate pothos after moving it indoors or outdoors.
- Filter intense window light with a sheer curtain.
- Avoid spraying foliage immediately before strong exposure.
- Reassess the position as seasonal sunlight changes.
- Keep roots appropriately watered without leaving the pot waterlogged.
- Inspect new growth for fresh damage.

Frequently Asked Questions
Can a sunburned Pothos leaf recover?
The dead or bleached area will not become green again. Undamaged portions can remain useful, and later leaves can grow normally after exposure is corrected.
Should I water more after sunburn?
Not automatically. Check the potting mix. Extra water does not repair burned foliage and can create a separate root problem.
Is a brown spot always sunburn?
No. Consider its location, texture, progression, and the plant’s recent history. Spreading wet lesions, pest signs, or root symptoms point toward other causes.
Can Pothos tolerate direct sunlight?
Pothos prefers moderate to bright light without strong direct exposure. Gentle exposure may be tolerated in some settings, but abrupt or intense sun can scorch previously shaded leaves.
