Pothos is one of the toughest houseplants around, and a classic recommendation for beginners. Even so, "I looked over and the leaves had turned yellow" is a surprisingly common problem — even with a plant this resilient.
There are 4 main causes of yellowing leaves, and the right fix for one can be the exact opposite of the right fix for another. So the first step is telling them apart correctly.
In this article, we'll walk through the 4 causes of yellowing pothos leaves, what to do for each one, and how long recovery typically takes.
Cause 1: Overwatering (the most common)
The most common reason pothos leaves turn yellow isn't too little water — it's too much.
What it looks like:
- Leaves turn yellow starting from the bottom (new growth at the top still looks fine)
- Yellowing leaves stay soft and limp rather than crispy
- The soil is always damp
- The pot feels heavy, or moss and mold are appearing on the surface
Pothos grows as a climbing plant in tropical rainforests, so its roots are surprisingly tolerant of drying out. Constantly wet soil actually stresses the plant.
What to do:
- Stop watering immediately and let the soil dry out completely
- Cut yellowed leaves off at the base (they won't recover, and removing them saves the plant's energy)
- Check that water drains from the bottom of the pot, and empty any water sitting in the saucer
- After 1–2 weeks, return to a normal rhythm: water only once the soil surface has dried out
Cause 2: Too little light / too much direct sun
Pothos prefers "bright shade." Either extreme can cause yellowing.
Not enough light
- The whole plant fades, turning yellowish-green to yellow
- Leaves come in smaller, and stems look stretched out (long gaps between leaves)
- On variegated varieties, the variegation fades
What to do: Move it near a window with a sheer curtain. Avoid direct sunlight.
Too much direct sun
- Parts of the leaf bleach to a pale color, then turn brown or black
- Yellowing appears at the same time
- Leaves feel thin and crispy to the touch
What to do: Move it out of direct sunlight right away. Be especially careful with sunny windowsills in summer.
Cause 3: Cold
Pothos is sensitive to cold — below 10°C (50°F), leaves turn yellow and drop.
What it looks like:
- Happens in winter or right after a sudden temperature drop
- Yellowing often starts from the leaf edges
- Dark spots may appear on the stems as well
What to do:
- Move it somewhere that stays above 15°C (59°F)
- Keep it away from windows (nights near the glass get much colder)
- Keep it out of the direct blast of a heater
- Trim back the yellowed leaves
Even after cold damage, pothos often bounces back with new growth once things warm up — so don't give up on it too soon.
Cause 4: Natural turnover of old leaves
Not all yellowing is a problem.
Plants naturally shed old leaves to make room for new ones, and during the growing season (spring through summer) it's completely normal for one or two lower leaves to yellow and drop.
Signs it's just natural turnover:
- New growth is coming in at the same time and the plant looks healthy overall
- Only old lower leaves are yellowing, about 1–2 per month
- There are no other warning signs
This is healthy metabolism — nothing to worry about. Let the leaves drop on their own, or snip them off at the base if the look bothers you.
A checklist for narrowing down the cause
When leaves turn yellow, run through these checks in order:
| Check | If YES, likely cause |
|---|---|
| Is the soil always damp? | Overwatering (most likely) |
| Has it been somewhere cold recently? | Cold |
| Is it getting strong sun, like a midsummer windowsill? | Direct sun |
| Is it sitting in a dark spot? | Not enough light |
| Healthy new growth, and only 1–2 leaves a month? | Natural turnover (normal) |
If more than one applies, fix the most likely environmental factor first — one change at a time. If you change everything at once, you won't know what actually helped.
How long recovery takes
Once the cause is fixed, here's the typical pace at which pothos gets back on its feet:
- Mild overwatering → new leaves start appearing in 2–3 weeks
- Severe root rot → repotting needed, recovery takes 1–2 months
- Cold damage → new growth about a month after things warm up
- Low light → leaf color starts returning in 1–2 weeks
Pothos has remarkable staying power — as long as the stems are still green, there's a good chance it will recover. If the stems haven't turned black and mushy, keep watching and don't give up.
Preventing yellow leaves
Habits worth building into your routine:
- Water only after the soil surface has dried (never water while it's still damp)
- Empty the saucer every time you water
- Keep the room around 15–25°C (59–77°F)
- Place it in bright shade (behind a sheer curtain)
- Once a month, lift the pot to check its weight
Green Logs lets you track watering with a window of a few days rather than a single fixed date — an easy way to keep up the "dry first, then wait a little longer" rhythm without having to remember it yourself.
