Why Are My Pothos Leaves Turning Yellow? (And How to Fix It) | Good Garden

Pothos has a reputation as one of the easiest houseplants to keep alive, which is exactly why it's so unsettling when yours starts turning yellow anyway. The good news: yellowing is almost always fixable once you know what's actually causing it.

Here's how to figure out which of the common causes applies to your plant and what to do about each one.

1. Overwatering (The Most Common Cause)

If the yellow leaves are soft, mushy or turning yellow starting from the base of the plant, overwatering is the most likely culprit. Pothos roots need oxygen as much as water and soil that stays constantly wet suffocates the roots, which shows up above the soil as yellowing.

How to check: Stick a finger into the soil up to the second knuckle. If it's still damp more than a couple of inches down, you're watering too often.

Fix: Let the soil dry out significantly between waterings. Pothos actually prefers to dry out almost completely before its next drink. If the pot has no drainage hole, that's worth fixing before anything else.

2. Underwatering

Less common than overwatering, but it happens especially if a plant gets forgotten during a busy week. Underwatered yellowing tends to come with crispy, dry leaf edges rather than the soft, mushy texture of overwatering.

Fix: Water thoroughly until it runs from the drainage hole, then get back on a more consistent schedule.

3. Too Much Direct Sun

Pothos is a low-to-medium light plant by nature. Direct, harsh sunlight especially through an unfiltered south or west facing window can scorch leaves, which sometimes shows up as yellowing (with brown, crispy patches) rather than classic sunburn.

Fix: Move it a few feet back from direct light, or filter it with a sheer curtain.

4. Natural Aging

Not all yellow leaves are a problem. Pothos regularly sheds its oldest, lowest leaves as it grows this is completely normal and not a sign anything is wrong, as long as it's just one or two older leaves at a time and the rest of the plant looks healthy.

Fix: Nothing needed. Just remove the yellowed leaf once it's fully yellow.

5. Nutrient Deficiency (The Most Overlooked Cause)

Here's the one that gets missed most often: a Pothos that's watered correctly, positioned correctly and still yellowing across multiple leaves not just the oldest ones is frequently just hungry. Pothos in a pot exhausts the nutrients in its soil over time and without replenishing them, growth stalls and leaves pale out even when everything else about its care is right.

This is the exact situation Growth Booster is built for, it's formulated specifically to push new leaf growth and bring stalled or yellowing plants back to active growing rather than just treating a symptom.

Putting It Together

If you've ruled out watering and light and your Pothos is still yellowing, nutrition is very likely the missing piece and it's the one cause that watering schedules and window placement can't fix on their own.

This is also a good moment to think about where your plant actually is in its growth cycle rather than treating every issue the same way. A Pothos that's rootbound and just repotted needs a very different kind of support than one that's rooted and simply stalled which is the whole idea behind our 4-stage growth ritual. If your Pothos has healthy roots already and just needs to get growing again, Growth Booster is stage two of that system feed it, give it a couple of weeks, and new growth should follow.
