Overwatered Pothos: Signs, Fixes and How To Not Do It Again

Overwatering kills more Pothos than anything else. It’s not dramatic or sudden — it happens slowly, while you’re trying to do the right thing, which is what makes it so frustrating when you finally realise what’s been going on.

The good news is that an overwatered Pothos is recoverable in most cases, sometimes even when things look pretty dire.

Here’s how to tell if yours is in trouble, and what to do about it.

Signs Your Pothos Is Overwatered

The tricky thing about overwatering is that its symptoms overlap almost entirely with underwatering.

Drooping leaves, yellowing, stalled growth — all of it can point to either problem.

This is why checking the soil is always step one.

The soil is wet or damp when it shouldn’t be. This is the big one, and it’s surprising how many people miss it. If your Pothos is looking rough and you go to water it and the soil is already wet — that’s your answer right there.

Yellow leaves, especially on the lower, older leaves. Some yellowing is normal as leaves age, but if multiple leaves are going yellow at once, overwatering is near the top of the suspect list. [Full guide to yellow Pothos leaves here.]

Drooping even though the soil is wet. A wilting plant sitting in damp soil is a classic sign that the roots are struggling. More on drooping here.

Mushy stems at the base. If the stem feels soft or looks discoloured where it meets the soil, root rot has progressed to the point where it’s affecting the stem itself. This is more serious.

Brown, mushy leaf tips or patches rather than the dry, crispy brown you’d get from underwatering or low humidity. [More on brown leaves here.]

Fungus gnats. These small flies breed in consistently moist soil. If you’ve suddenly got tiny flies hovering around your plant, it’s a strong sign the soil has been staying wet too long. They’re annoying but not particularly harmful to the plant directly — the overwatering causing them is the real problem. Don’t panic, just fix the watering.

Mushrooms. Less common, but it happens. Finding a small mushroom growing in your Pothos pot is a sign that the soil has been wet enough, long enough, to support fungal growth. Not dangerous to the plant, just a firm message from your Pothos that things need to dry out.

Why Overwatering Is So Easy To Do

Most overwatering isn’t caused by pouring too much water in at once. It’s caused by watering again before the soil has had a chance to dry out from the last time.

The “water once a week” advice that gets repeated everywhere is a big part of the problem. Watered once a week in summer when the plant is actively growing and the soil dries quickly? Probably fine. Watered once a week in a dim room in January when the plant is barely growing and the soil takes weeks to dry out? Classic overwatering setup.

Pots without drainage holes make this worse. Water has nowhere to go and just sits at the bottom, keeping the lower roots permanently wet. If your Pothos is in a pot without drainage, that needs to change. Use it as a decorative cachepot and put a plastic pot with drainage holes inside it instead.

How To Fix An Overwatered Pothos

How you fix it depends on how bad things have got.

Mild Overwatering (Soil Is Wet, No Root Rot Yet)

If you’ve caught it early and the roots are still firm and white or pale tan, you don’t need to do much. Stop watering, move the plant somewhere with better light and airflow if possible, and wait. Let the soil dry out completely before you water again. Then [adjust your watering routine] so you’re checking the soil rather than following a schedule.

Moderate To Severe (Root Rot Has Set In)

If the roots are brown, black, or mushy when you check them, root rot has started. This needs more active intervention.

Here’s what I do, and it works nine times out of ten, even when the root situation looks pretty grim:

1. Take the plant out of its pot and shake off as much of the old soggy soil as you can.
2. Cut off every rotten root — brown, black, mushy, smelly. Cut back to healthy white or firm tissue. Don’t be precious about it. Leaving rot behind means it spreads.
3. If there are only a few short root stubs left after cutting, that’s fine. Pothos roots regrow readily.
4. Put the plant in a jar or vase of clean water rather than repotting it straight back into soil. Water makes it easy to monitor root regrowth — you can see exactly what’s happening without disturbing the plant. (Note: roots grown in water are structurally different to soil roots, so when you eventually move it back to soil, expect a short adjustment period while it adapts.)
5. Change the water every few days to keep it fresh, keep it somewhere bright but not in direct sun, and wait. New roots usually start appearing within a couple of weeks.
6. Once you’ve got a decent amount of new root growth, pot it into fresh, well-draining soil.

When It’s Really Bad (Rot Spreading Up The Stem)

If the rot has moved out of the roots and up into the stem itself, you’re in nuclear option territory. The affected stem isn’t coming back, but the plant might.

I had one that got to this point — the rot was visibly creeping up the stem and there was no saving the root system. What I did was take cuttings from the healthy stem growth above the rot, let them callous for a few hours, and then set them up in damp moss in a clear plastic box with a few air holes poked in the lid. The high humidity inside the box encourages root development without the cutting having to work too hard. It takes longer than water propagation but it works well for cuttings that are already a bit stressed.

Healthy nodes with no sign of rot, into damp moss, in a humid environment, out of direct sun. It’s slower than you want it to be, but it works.

How To Stop Overwatering Your Pothos

The fix is the same as the fix for getting watering right generally: check the soil before you water, rather than watering on a schedule.

The soil should be almost completely dry before you water again. Not the top inch — all the way through. Use a moisture meter if you’re using standard potting compost (stick it into the middle of the pot, wait until it reads 2 or 3 before watering). If you’re using a chunky mix, the lift test is more reliable: pick the pot up and feel how heavy it is. Once you know what bone dry feels like versus freshly watered, it becomes second nature.

A few other things that help:

Make sure there are drainage holes. Every time, no exceptions.

Don’t go up too many pot sizes when repotting. A small plant in a huge pot of soil will sit in damp compost for weeks because there aren’t enough roots to absorb the moisture. One pot size up is enough.

Increase light. More light means the plant is more active and uses water faster, which means the soil dries out at a more reasonable rate. A Pothos in a dim spot is always going to be more at risk of overwatering than one in a bright spot, because the soil just doesn’t dry out fast enough.

If you’re someone who loves to water, self-watering pots are genuinely useful. The plant draws up moisture from a reservoir as it needs it, so you get to water (filling the reservoir) without waterlogging the roots. [More on self-watering pots here.]
