Why Monstera Leaves Turn Yellow (And How to Fix It)

A yellowing monstera leaf is almost always a watering problem — most often too much water sitting in dense soil, occasionally too little. But not always. Where the yellow leaf sits on the plant, how fast it turned, and whether the yellow is uniform or patchy will tell you which cause you're dealing with. Start by feeling the soil two inches down.

First, check the soil before you change anything

Push a finger into the potting mix up to the second knuckle, roughly two inches. Don't judge by the surface — the top half inch of a monstera pot dries out within a day or two of watering while the root zone underneath stays soaked for a week.

If the soil at two inches feels cool and damp and clings to your finger, the plant is holding more water than it can use. If it's dry, crumbly, and pulls away from the sides of the pot, you've gone too long between waterings. If it feels barely moist, like a wrung-out sponge, watering isn't your problem and you should look at light and nutrients instead.

Also lift the pot. A monstera that's just been watered is noticeably heavy; the same pot a week later, when it's ready for water again, feels obviously lighter. Doing this for a month teaches you more about your plant's actual needs than any watering schedule.

Overwatering: the most common cause by far

Overwatering yellow looks like this. The affected leaves are usually the lower and older ones, closer to the soil. The yellow is soft and uniform — the whole leaf goes a flat pale yellow rather than developing patches. Often there's a brown spot in the middle of the yellow with a yellow halo around it, and the leaf feels limp and slightly squishy rather than papery. New growth slows down or stops. Sometimes a new leaf unfurls smaller than the last one, or emerges already yellowing at the tip.

What's happening underground is that waterlogged soil has pushed the air out of the pockets between particles. Monstera roots need oxygen as much as they need water. When they can't get it they start dying back, and the plant, unable to take up water through dead roots, drops its oldest leaves first to cut its losses. That's why overwatering and underwatering can look so similar at the leaf — both end in a plant that can't move water. We cover the telltale differences in overwatering vs underwatering.

To confirm, slide the plant out of its pot. Healthy monstera roots are firm and pale — white to light tan — and snap rather than smear when you bend them. Rotting roots are brown or black, mushy, and the outer layer slips off between your fingers like a wet sock, leaving a thin string inside. Healthy soil smells earthy and faintly sweet. Root rot smells sour and swampy, a bit like a vase of flowers left too long.

What to do about it

If most of the roots are still firm, you can often fix this without repotting: stop watering, move the plant somewhere brighter and with a little air movement, and let the pot dry down to properly dry at two inches before the next drink. That may take two or three weeks. Empty the saucer every time you water — a pot standing in a centimetre of water never really drains.

If a significant share of roots are mushy, repot. Shake off the old soil, cut away every soft root with clean scissors, and put the plant into a pot only slightly larger than the remaining root ball, in a chunky mix — regular potting soil cut with orchid bark, perlite, or coco chips at roughly one part chunk to two parts soil. Use a pot with drainage holes. A monstera in a pot two sizes too big stays wet for weeks because there are no roots in most of that soil to drink it.

Leaves that have already turned yellow will not turn green again. Cut them off at the base of the petiole once they're more yellow than green; they're costing the plant more than they contribute.

Underwatering: less common, but it happens

A thirsty monstera yellows differently. The leaf edges and tips go brown and crisp first, and the yellowing spreads inward from there. The leaf feels dry and papery, not limp. The whole plant droops in a way that perks up within hours of a thorough watering. The soil has shrunk away from the sides of the pot, and when you water, it runs straight down that gap and out the bottom without wetting the middle.

If that's your plant, don't just splash water on top. Fix the channelling by bottom-watering: stand the pot in a sink or basin with a few inches of water and leave it for twenty to thirty minutes until the surface of the soil darkens with moisture, then drain it fully. Do that once and go back to normal top-watering after.

Light problems look different again

A monstera that isn't getting enough light yellows slowly and evenly, usually across many leaves rather than one or two, and the new leaves come out small and without splits or holes. This yellow is more of a pale, washed-out green than a real yellow, and it's accompanied by long stretched stems reaching towards the window.

Too much direct sun does the opposite: it bleaches. You'll see pale yellow or whitish patches on the parts of the leaf that face the window most directly, often with dry brown centres where the tissue has actually burned. It shows up on the top and outer leaves, not the shaded lower ones. A monstera wants bright indirect light — a spot where you can see the sky but not the sun itself for most of the day, or a couple of feet back from a south or west window.

Nutrient deficiency and old age

If watering and light are both fine and leaves are still yellowing, consider feeding. A nitrogen-hungry monstera yellows its oldest leaves first, uniformly, because the plant moves nitrogen out of old tissue to build new growth. Magnesium deficiency looks different — the veins stay dark green while the tissue between them goes yellow, giving a marbled effect, and it hits mid-age leaves. Either way, a balanced liquid houseplant fertiliser at half the label strength, every third or fourth watering during spring and summer, will resolve it within a month or two. If you haven't repotted or fed in more than two years, the mix is almost certainly exhausted.

And sometimes a yellow leaf means nothing at all. Monsteras shed their oldest leaves as a matter of course. One lower leaf yellowing every few months, while everything else looks good and new leaves keep coming, is normal. It only becomes a signal when several go at once, or when the plant isn't replacing them.

If you're not certain your plant is actually a monstera deliciosa — it's commonly confused with philodendron and with monstera adansonii, which want slightly different care — a photo ID in the Planted app will settle it in a few seconds.

A quick way to narrow it down

Look at three things in this order.

Placement. Bottom, oldest leaves only means overwatering, nitrogen, or normal ageing. Top and outer leaves means light. Scattered across the plant means pests or a root problem.

Pattern. Uniform soft yellow means water or nitrogen. Yellow between green veins means magnesium. Yellow with a brown mushy centre means overwatering. Yellow with a crisp brown edge means underwatering. Bleached pale patches mean sunburn.

Speed. Overnight collapse across many leaves points to a root problem or a sudden environmental shock — a cold draught, a radiator, a move. Slow drift over weeks points to light or feeding.

Don't forget pests

Turn a yellowing leaf over. Spider mites cause a fine yellow stippling — a scatter of tiny pale dots, as if the leaf were sprayed with a faint mist — and leave webbing where the leaf meets the stem. Thrips cause silvery streaks and distorted new growth. Both cause yellowing that doesn't match any watering pattern. Wipe the leaves down, both sides, and treat with insecticidal soap weekly for three weeks if you find anything moving.

Once you've fixed the cause, expect the plant to look unchanged for a few weeks. Recovery shows up as a new leaf, not as old ones greening back up. If a healthy new leaf unfurls a month after your intervention, you got it right. For a related problem on a different plant, the brown-spot diagnostics in fiddle leaf fig brown spots use the same placement-and-pattern logic.

Common questions

Should I cut off yellow monstera leaves?

Yes, once a leaf is more than about half yellow. It won't recover its colour, and the plant is still spending energy maintaining it. Cut the petiole close to the main stem with clean scissors. If a leaf is only slightly yellow at one edge, leave it — it's still photosynthesising.

My monstera has one yellow leaf but looks fine otherwise. Should I worry?

Probably not. A single lower leaf yellowing while the plant is pushing out new growth is routine turnover. Watch it for a few weeks. If a second and third leaf follow, or new growth stalls, then start investigating.

Can yellow leaves turn green again?

No. Chlorophyll loss in a leaf is permanent. The exception is a very mildly pale leaf caused by a nutrient shortage, which can regain some colour after feeding, but a leaf that has gone properly yellow is done. Judge your fix by the health of new growth instead.

How long after overwatering will my monstera recover?

If you caught it early and only the top of the soil was the problem, you may see a new leaf within three to four weeks. If you had to cut rotten roots and repot, expect six to twelve weeks of no visible growth while the plant rebuilds its root system. Keep it warm, bright, and on the dry side of moist during that period, and don't fertilise until you see new growth.
