Why Are My Pothos Leaves Turning Brown?

Brown leaves mean about eleven different things, which is why every article you’ve read on this has given you a list of causes and left you no closer to knowing which one is yours.

So this isn’t a list. It’s a process of elimination.

Here’s the thing nobody tells beginners: reading a plant from its leaves is a skill, and it takes a while to develop.

Experienced growers aren’t recognising brown patches from a mental catalogue. They’re asking a series of questions and ruling things out until only one answer is left. That’s learnable, and it’s what this article is going to walk you through.

One reassurance before we start. A brown leaf is not an emergency, and a plant with a couple of brown leaves is usually a perfectly healthy plant.

Damaged leaves also never heal, so a leaf that turned brown three months ago and hasn’t changed since is a historical record, not an active problem.

First: is this actually a problem?

Three quick checks that resolve a surprising number of cases.

Is it one small mark on one leaf? Then it’s nothing. Plants get blemishes. A leaf can catch on something, get knocked in transit, or simply develop a small imperfection for no reason you’ll ever identify. That’s just the way plants be. If you look closely enough at any plant in any nursery, you’ll find similar marks on half of it.

Was the leaf brown when it first came out? New Pothos leaves emerge rolled inside a sheath, and occasionally one unfurls already marked. That damage happened while the leaf was forming, weeks ago, and it tells you nothing about how the plant is doing now.

Is it the oldest leaf on the vine? Plants shed old leaves on purpose. If the lowest, oldest leaf is going brown or yellow while everything above it looks fine, that’s the plant retiring a leaf it no longer wants to pay for.

If none of those apply, keep going.

The questions, in order

1. How many leaves are affected?

One leaf, or a few in the same spot: something happened to that leaf. Physical damage, something touching it, a pet, a knock. Local cause.

Leaves scattered across the whole plant: something is wrong with the plant’s conditions. Watering, roots, light, temperature. Systemic cause.

This single question splits the diagnosis in half and it’s the one most people skip.

2. Where on the leaf is the brown?

Just the very tips. Usually watering related, and the least alarming pattern there is.

The edges, going inwards. Often dryness, heat or draught.

Large patches in the middle or across the leaf. Sunburn or serious root trouble.

Small discrete dark spots rather than solid brown areas. That’s a different symptom with different causes, and it has its own article.

3. What does the brown bit feel like?

Get your fingers on it. This is the single most useful test in this article.

Soft, mushy, wet. That’s overwatering. When a plant takes up more water than it can move out through its leaves, the cells swell until they rupture, and you get soft brown patches with no crispness at all.

Dry, crispy, papery. That’s the plant not getting enough water to that leaf. Which does not automatically mean you’re underwatering, and I’ll come back to that, because it’s the single biggest trap in this whole diagnosis.

4. Has anything changed in the last few weeks?

Moved it to a new spot. Repotted it. Heating came on. Window started being left open. New radiator. Different room.

Plants respond to change on a delay, so the brown leaves you’re looking at today are often reporting something that happened a fortnight ago. If you moved the plant three weeks ago and forgot, that’s your answer.

5. Is it touching anything?

Leaves pressed against cold window glass in winter will brown where they touch. Same for a leaf resting on a radiator, a hot windowsill, or a wall. It’s an extremely common cause and an extremely easy fix.

6. Do you have a cat?

You’d be amazed. Chewed leaves brown at the damage site and it looks nothing like a bite by the time you notice it.

Cats, dogs, toddlers and hoovers cause a substantial share of mystery leaf damage. If the marks are at one height, on the leaves nearest the edge of the shelf, or on the vines that hang lowest, you have your culprit. Ask me how I know that this is the first thing experienced growers check.

7. What do the roots look like?

If the browning is spread across the plant and nothing above has explained it, take it out of the pot and look.

Healthy Pothos roots are firm. Note that some Pothos have naturally darkish roots, so colour alone isn’t the test. What you’re looking for is mushy and unpleasant. If you find it, you have your answer and there’s a whole article for it.

Root Rot In Pothos: Can You Save It?

The causes, once you’ve narrowed it down

Watering, in both directions

The trap here is that overwatering and underwatering can produce similar-looking brown leaves, because both end with the plant not getting water to its foliage.

Overwatering does it by damaging the roots so they can’t take water up. Underwatering does it by there being no water to take. The plant looks thirsty either way, which is why so many people water a struggling plant more and make it worse.

The feel test in question three is how you tell them apart. Mushy means too much. Crispy means too little.

Root problems

Brown leaves scattered across an otherwise established plant, with soil that never seems to dry, is root rot until proven otherwise.

Physical damage

One-off, localised, doesn’t spread, doesn’t change. Nothing to treat. The leaf will carry that mark for the rest of its life and the plant does not care.

Cold and draughts

Pothos handle cool conditions better than people expect, but they don’t enjoy a cold draught, and browning at the edges of leaves nearest a door or a draughty window in winter is a common pattern. Cold stress also makes a plant more attractive to pests, which is a separate reason not to leave it there.

Sunburn

Yes, a Pothos can scorch, usually as pale bleached patches that go brown, on the leaves most directly exposed.

But I want to be careful here, because this is where a lot of people go wrong. Reading “sunburn” and moving the plant into a dark corner is a much worse outcome than a couple of scorched leaves.

Sunburn is a nuisance, not a catastrophe. The scorched leaves won’t recover, but the plant adapts. Growth that develops in brighter conditions is physically built for it, and a Pothos that has acclimated to a bright spot will be a substantially better plant than the one sulking away from the window. If you’ve just moved a plant somewhere much brighter, expect a few casualties on the old leaves and judge the decision by what grows next, not by what got damaged in the transition.

Pests

Thrips and spider mites both produce damage that dries out and browns. Look for the finer pattern underneath: silvery or bronze patches and stippling rather than solid brown areas, and check the undersides.

Brown tips do not mean you need to mist

This one gets its own section because it’s the most common wrong answer on the internet for this exact symptom.

Brown crispy tips get blamed on low humidity constantly, and the recommended fix is always misting. It doesn’t work. Misting raises the humidity around a plant for a few minutes and then it evaporates, which changes nothing about a leaf tip that browned over several weeks.

Brown tips on a Pothos are far more likely to be about watering, roots, or a draught. Those are the things to investigate. If you want the full argument on humidity, it’s here.

Pothos Humidity: What You Need To Know (And Why Misting Does Nothing)

Should you cut the brown bits off?

You can, and it does no harm, but understand what happens.

When you cut into a leaf, the plant seals the wound to stop infection getting in, and that seal is itself brown. So you trim off the brown edge and the leaf grows a new, thinner brown edge along your cut line.

Cosmetically it’s usually an improvement, particularly if you follow the leaf’s natural shape. Just don’t expect a leaf that looks untouched, and don’t do it expecting a health benefit, because there isn’t one.

If a leaf is more brown than green, take the whole leaf off at the stem instead. It isn’t contributing anything and the plant will stop spending resources on it.

Frequently asked questions

Why are my Pothos leaves turning brown at the tips?

Most often watering related, either too much or too little, and sometimes a draught or a heat source nearby. If the tips are crispy and dry the plant isn’t getting enough water to the leaf edges, which can mean underwatering or damaged roots that can’t take water up. It’s rarely about humidity, despite what you’ll read.

Will brown leaves on a Pothos turn green again?

No. Leaf damage is permanent. Once a section of leaf has browned, those cells are dead and won’t recover. Judge whether a problem is fixed by what the new growth looks like, not by whether old damage improves.

Should I cut brown leaves off my Pothos?

Only if you want to. Trimming brown sections is cosmetic and the plant will seal the cut, which leaves a thin brown line along the edge. If a leaf is mostly brown, removing it entirely is worthwhile since the plant stops spending resources maintaining it.

Are brown leaves a sign of overwatering or underwatering?

Both are possible, which is why the texture matters. Soft and mushy brown patches point to overwatering, where cells have taken on more water than they can hold. Dry and crispy brown patches point to the leaf not receiving enough water, from underwatering or from roots too damaged to supply it.

Can too much light cause brown leaves on a Pothos?

Yes, as bleached patches that turn brown on the most exposed leaves. It’s worth keeping in perspective. Scorched leaves don’t recover, but the plant acclimates and new growth will be adapted to the brighter position. Moving a Pothos into a dark corner to avoid burn causes far more problems than the burn does.

Do brown leaves mean my Pothos is dying?

Almost never. A few brown leaves on a plant that’s still producing new growth is a plant that’s fine. The signal worth worrying about is not the damaged leaves but whether new leaves are still appearing, and whether they’re appearing undamaged.
