Why Are My Pothos Leaves Turning Yellow?

You walk past your pothos, spot a bright yellow leaf and immediately wonder what went wrong. Fortunately, one yellow leaf isn't enough to diagnose a disaster.

Yellowing is a general sign that a plant is under stress, which means the goal isn't just to remove the yellow leaf. First, look at where the yellowing is happening, how quickly it's spreading, and what the soil feels like.

1. The soil is staying too wet

Start here, especially if several lower leaves are turning yellow at the same time.

Pothos like moisture, but their roots still need oxygen. When potting mix stays saturated for too long, the roots can become stressed and may eventually begin to rot.

What to do

Don't automatically water your pothos because a certain number of days have passed. Check the potting mix first. Let it dry moderately between waterings, then water thoroughly and allow excess water to drain from the pot.

If the soil is soaking wet and the plant is continuing to decline, check the roots. Healthy roots should feel firm rather than soft and rotten.

2. Your pothos actually needs water

Here's where plant troubleshooting gets annoying: too much and too little water can produce some of the same symptoms.

A thirsty pothos may droop before you see significant yellowing. Very dry soil may also shrink away from the sides of the pot.

3. It's not getting the right light

Pothos are famously tolerant of lower light, but tolerant doesn't necessarily mean ideal.

In very low light, growth can become weaker and the plant may lose some of its variegation. On the opposite extreme, strong direct sun can bleach or scorch foliage.

For healthy growth and good variegation, a spot with bright, indirect light is a good target for most pothos.

4. An older leaf is simply retiring

Sometimes the diagnosis is wonderfully boring.

Older pothos leaves naturally turn yellow and eventually drop as the plant ages. If one older leaf near the base of an otherwise healthy, actively growing vine turns yellow, it may simply be normal leaf turnover.

5. Too much fertilizer has built up in the soil

More fertilizer does not equal more plant.

Excess fertilizer can cause salts to accumulate in potting mix. Fertilizer or mineral salt problems may show up as discoloration, yellowing, or browning around leaf tips and margins.

If you've been fertilizing frequently, resist the urge to add another dose while you're troubleshooting. More isn't likely to fix a plant already stressed by excess fertilizer.

6. The roots need attention

Sometimes the real clue isn't on the leaf at all — it's inside the pot.

A pothos that has been in the same container for a long time may become crowded. Root problems can also develop when the potting mix drains poorly or remains wet for extended periods.

If watering and light seem reasonable but your plant continues to struggle, gently slide it from the pot and inspect what's happening below the soil line.

7. Something in its environment changed

Think about what happened before the yellow leaves appeared.

Did you move the plant? Change windows? Repot it? Bring it home from the store? Start fertilizing? Turn on the heat for winter?

Plant problems are easier to diagnose when you look for changes rather than treating the yellow leaf as an isolated symptom.

Should you remove yellow pothos leaves?

Yes. Once a pothos leaf has turned fully yellow, it isn't going to become green again. You can remove it with clean scissors or pruning shears.

But removing the leaf doesn't fix whatever caused the yellowing. Think of the leaf as the clue, not the problem itself.

Will a pothos recover from yellow leaves?

Often, yes. Pothos are resilient plants. If you identify and correct the underlying problem while the roots and stems are still healthy, the plant can continue producing new growth.

Watch the new growth after making a change. Existing damaged leaves won't repair themselves, so healthier new leaves are usually a better sign of recovery.
