Why Are My Monstera Leaves Curling? (And How to Fix It)

Why Your Monstera Is Curling (Quick Answer)

A curling Monstera is almost always telling you about water — and the soil tells you which direction the problem runs. If the soil is dry and the leaves are curling inward like a taco, the plant is thirsty or the air is too dry: that's the most common cause indoors, and the leaves usually relax within a day of a proper soak. If the soil is wet and staying wet, and the leaves are curling and yellowing or drooping, the roots are the problem, not the watering can — that's root rot, and watering more makes it worse.

So before anything else, stick a finger two inches into the soil. Bone dry and pulling from the pot edge means underwatering. Soggy days after you last watered means stop and check the roots. One more thing that panics people needlessly: a brand-new Monstera leaf always emerges as a tightly rolled cigar and unfurls over several days — that's normal, not curling. If you're not sure what you're looking at, our plant diagnosis tool reads a photo and narrows it down in seconds.

Quick Diagnosis: Check the Soil, Then Match the Curl

Monstera curling splits cleanly by soil moisture, so start there. Lift the pot and feel the soil, then match what you see to the row below.

The reason the soil check works is physical: when a Monstera loses water faster than its roots can resupply, the leaf cells lose turgor (internal pressure) and the leaf rolls to shrink the surface it exposes to the air, slowing moisture loss. Rehydrate it and the pressure — and the flat leaf — comes back. That's also why the wet-soil version is so easy to get backwards.

The Common Cause: Thirst and Dry Air (Dry Soil)

Most curling Monsteras indoors are simply underwatered, under-humidified, or both. Monstera deliciosa likes its top two to three inches of soil to dry out and then a thorough drink — not frequent little sips that never reach the deeper roots. When it goes too long between waterings, the newest and largest leaves curl first because they lose the most moisture.

The fix is a real soak, not a splash: water slowly until it runs from the drainage hole, let it drain, and empty the saucer. If the mix has gone hydrophobic and water runs straight through without wetting it, bottom-water instead — set the pot in a tray of water for 20 to 30 minutes so it wicks up evenly. A properly rehydrated Monstera usually relaxes its curl within hours to a day.

Humidity is the other half. Monstera does best around 50 to 70% humidity, and when the heat comes on in winter and indoor air drops below 40%, the leaf edges roll under and crisp. A small room humidifier is far more effective than misting, which raises humidity for a few minutes and then it's gone. Group your tropicals together and keep the plant clear of heat vents and radiators, which dry the nearest leaves fastest.

"Is My New Leaf Supposed to Be Curled?"

Yes — and this trips up almost every new Monstera owner. Every Monstera leaf emerges as a tightly furled cigar or spear and slowly unrolls over several days into the flat, fenestrated paddle. A single rolled new leaf at the growing tip is healthy new growth, not a curling problem, and there's nothing to fix.

The one time a new leaf needs help is when it stalls — starts to open, then stops and stays partly stuck or crispy at the edges. That's almost always very dry air: the emerging leaf dries out before it can finish unfurling. Bump up the humidity around the plant (a humidifier or a temporary clear cover) and keep the soil evenly moist while that leaf opens. Don't force a stuck leaf apart by hand — you'll tear it. If old, fully-opened leaves are the ones curling, skip this section; that's a water or root issue, covered above and below.

When Curling Means Root Rot (Wet Soil)

This is the version people misread. A Monstera with curling, drooping, yellowing leaves sitting in soil that stays wet for days is usually overwatered, and the instinct to water a sad-looking plant digs the hole deeper. Waterlogged soil pushes the oxygen out, the fine roots suffocate and rot, and rotten roots can't move water even while they're sitting in it. The University of Maryland Extension notes that root rot causes plants to wilt "even when adequate moisture is present in the potting media" — which is exactly why a droopy, wet-soil Monstera gets watered again and pushed further into rot.

Check the stem base and smell the soil. Firm base, earthy smell: probably just needs to dry out — hold off watering and let the top few inches dry. Soft, mushy, or sour-smelling base: unpot it, rinse the roots, cut away everything brown and mushy with sterilized scissors, and repot into a chunky aroid mix (bark, perlite, a little coir) in a pot with a drainage hole. Our full root rot rescue guide walks the save-vs-restart call, and Monstera propagates so readily that a badly rotted one is often a strong candidate for the cut-and-restart route. If the whole plant is yellowing rather than curling, start with our Monstera yellow leaves guide instead.

The Other Causes: Salt Burn, Heat, and Thrips

Once you've ruled water in or out, three culprits remain:

• Fertilizer and mineral salt burn. If you feed heavily and see crispy, curling leaf margins with a white crust on the soil surface, that's salt buildup drawing moisture back out of the roots. Flush the pot with plain water several times to leach the salts, then cut back to a diluted feed during the growing season only.
• Heat and harsh sun. Monstera scorches in direct afternoon sun through a hot window and curls to reduce the light and heat hitting the leaf. Bright indirect light is the target; pull it a few feet back from the glass or filter with a sheer curtain.
• Thrips. If the old leaves are flat but the newest growth comes in twisted and puckered with silvery streaks and tiny black specks, that's thrips — Monstera's large, tender unfurling leaves are a favorite target. Treat the pest; the already-distorted leaf won't straighten, but new growth comes in normal once they're gone.

Will Curled Monstera Leaves Uncurl?

It depends on the cause. Curl from a quick, reversible stress — a thirsty plant or a temporary humidity dip — relaxes once you fix it, often within hours to a day for underwatering. Those leaves recover on their own; there's nothing to cut.

Curl from root rot, salt burn, or thrips damage is different: that tissue is damaged and the leaf usually stays curled or distorted permanently, even after you correct the cause. The plant just puts out normal new leaves going forward. You can trim a badly distorted or crispy leaf for looks, but there's no rush — a leaf that's still mostly green is still feeding the plant. Fix the underlying cause and judge your success by the next leaf, not the damaged one.
