Why Are My Pothos Leaves Turning Yellow? (7 Causes + Easy Fixes)
You walk past your pothos and notice it — a leaf that was green yesterday is now unmistakably yellow. Then you notice another. Then another. The good news: yellow leaves on pothos almost always have a fixable cause, and once you know which one you’re dealing with, the fix is straightforward.
This guide walks through every cause of pothos yellowing — from the most common to the less obvious — with clear signs to help you distinguish between them and concrete steps to fix each one.
Quick Diagnosis: What Pattern Are the Yellow Leaves?
| Yellow pattern | Most likely cause |
| Lower leaves yellowing, soil stays wet | Overwatering or root rot |
| Entire leaves yellow, soil bone dry | Underwatering |
| Pale, washed-out yellow on all leaves | Too little light |
| Yellow with brown edges, white soil crust | Over-fertilizing or salt buildup |
| Yellow with tiny spots or webbing | Pests (spider mites) |
| 1–2 old lower leaves yellowing, plant otherwise healthy | Natural aging — completely normal |
Cause 1: Overwatering (Most Common)
Signs This Is Your Problem
- Yellowing starts with lower, older leaves
- Soil feels wet or damp even when you haven’t watered recently
- The pot feels heavy
- Stems near the soil may feel soft or mushy
How to Fix It
Stop watering immediately and let the soil dry out completely before watering again. Remove the plant from its pot and check the roots — healthy roots are white or light tan; rotted roots are brown, black, and mushy. If you find rot, see Cause 6 below.
Going forward: water only when the top 1–2 inches of soil feel dry. A moisture meter makes this foolproof — water when the reading drops to 3 or below. Make sure your pot has drainage holes and empty the saucer within 30 minutes of watering.
Cause 2: Underwatering
Signs This Is Your Problem
- Leaves yellow and the plant looks wilted or droopy
- Soil is completely dry and pulling away from the pot edges
- Crispy brown tips alongside the yellowing
- Pot feels very light
How to Fix It
Water thoroughly until water flows from the drainage holes. If the soil is very dry and compacted, it may repel water — let it sit in a tray of water for 30 minutes to rehydrate from the bottom, then drain. Most pothos recover from underwatering within 24–48 hours of a good drink.
Cause 3: Too Little Light
Signs This Is Your Problem
- Leaves are more pale yellow-green than bright yellow
- Variegated varieties losing their pattern, reverting to green
- New growth is small and the plant grows very slowly
- Plant is in a dark corner or a room with no natural light
How to Fix It
Move the plant closer to a window with bright indirect light. A spot 3–5 feet from a south or east-facing window is ideal. If your space genuinely lacks natural light, a grow light set 6–12 inches above the plant for 12–14 hours a day will compensate effectively.
Cause 4: Nutrient Deficiency
Signs This Is Your Problem
- Yellowing appears between leaf veins (interveinal chlorosis) — veins stay green while the tissue between them turns yellow
- Plant has been in the same soil for 2+ years
- You rarely or never fertilize
How to Fix It
Feed with a balanced liquid fertilizer (10-10-10 or 20-20-20) diluted to half the recommended strength. Fertilize monthly during spring and summer. If the plant has been in old, depleted soil for years, consider repotting into fresh potting mix with added perlite.
Cause 5: Temperature Stress or Cold Drafts
Signs This Is Your Problem
- Yellowing appeared suddenly, especially in winter
- Plant is near an exterior door, drafty window, or air conditioning vent
- Leaves may have dark patches alongside the yellowing
How to Fix It
Move the plant away from cold drafts and vents. Pothos handles temperatures down to about 55°F (13°C) but suffers with sudden cold exposure. Keep it in a stable spot where temperatures stay consistently between 65–85°F.
Cause 6: Root Rot (Serious)
Signs This Is Your Problem
- Multiple yellowing leaves despite correct watering
- Stems near the soil are soft, black, or smell musty
- Roots are brown, black, or mushy when you check
- The plant continues to decline despite letting soil dry out
How to Fix It
Remove the plant from its pot. Rinse the roots under water. With sterile scissors, cut off all brown and mushy roots — cut back to where the root is healthy and white. Let the roots air-dry for an hour. Repot in fresh, well-draining potting mix in a clean pot with drainage holes. Don’t water for 3–5 days after repotting to let any cut ends callous.
Cause 7: Normal Aging — Don’t Panic
If one or two of the oldest, lowest leaves on your pothos turn yellow and fall off while the rest of the plant looks healthy and is putting out new growth — this is completely normal. Plants shed old leaves as part of their natural growth cycle. No action needed; just remove the yellow leaf and move on.
Should I Cut Off Yellow Pothos Leaves?
Yes. Yellow leaves won’t turn green again — the damage is permanent. Remove them with clean scissors or pinch them off at the stem. This improves the plant’s appearance, prevents any potential fungal issues, and lets the plant redirect energy to healthy growth. Always cut as close to the main stem as possible.
Frequently Asked Questions
How quickly can yellowing pothos leaves be fixed?
The yellow leaves themselves can’t be fixed — they won’t turn green again. But if you identify and fix the underlying cause, new healthy leaves should emerge within 2–4 weeks. The plant’s overall condition should visibly improve within 1–2 weeks of correcting the problem.
Why is my pothos turning yellow even though I water it correctly?
If watering isn’t the issue, check light (most common overlooked cause), temperature exposure, and pests. Inspect the undersides of leaves carefully with a magnifying glass for spider mites — they’re tiny and easy to miss. Also check if roots are severely pot-bound.
Can I save a severely yellowed pothos?
Usually yes, as long as some healthy green stems remain. Identify the cause, fix it, and the plant will produce new growth from healthy nodes. Even a pothos that’s lost most of its leaves can recover if at least a few nodes with healthy tissue remain on the stems.
