Curling Monstera leaves can look alarming, but in most cases it's your plant's way of signaling a simple imbalance in water, light, or humidity. Take a breath — this guide will help you pinpoint the exact cause and fix it before any lasting damage occurs.
Quick Diagnosis
| What you see | Most likely cause | First fix |
|---|---|---|
| Leaves curling inward with dry, crispy edges | Underwatering or low humidity | Check soil moisture and water thoroughly |
| Leaves curling with yellowing and soft, mushy stems | Overwatering or root rot | Check roots, let soil dry out |
| New leaves emerging small and curled, little growth | Too much direct light or heat stress | Move away from harsh sun |
| Leaves curling plus pale or faded color | Too little light or nutrient deficiency | Increase light, check fertilizer schedule |
Cause 1: Underwatering and Low Humidity
The most common reason Monstera leaves curl inward is simple thirst. When roots can't pull up enough moisture, the plant reduces leaf surface area by curling to slow water loss — a defense mechanism, not a sign of permanent harm. Check the soil by pushing a finger two inches deep; if it's bone dry, that's your answer.
Monsteras are tropical understory plants, so they also appreciate humidity above 50%. In dry winter air or air-conditioned rooms, leaves can curl even when the soil is adequately moist. Grouping plants together, using a pebble tray, or running a humidifier nearby can make a noticeable difference within days.
When you do water, soak the pot thoroughly until water runs from the drainage holes, rather than giving small sips. For a deeper dive into getting your watering rhythm right, see our guide on how often to water houseplants.
Cause 2: Overwatering or Root Rot
Ironically, too much water causes curling too — but it looks different. If curling is paired with yellowing leaves, dark or mushy stems, or a sour smell from the soil, root rot is the likely culprit. Damaged roots can't absorb water properly, so the leaves curl and wilt even though the soil feels wet.
Gently slide the plant out of its pot and inspect the roots. Healthy roots are firm and white or tan; rotten ones are brown, black, and mushy. If you catch it early, trim away affected roots, let the remaining ones air dry briefly, and repot into fresh, well-draining mix. Our article on how to save a houseplant from root rot walks through the full recovery process step by step.
To prevent recurrence, always use a pot with drainage holes and a chunky, aerated potting mix. A moisture meter takes the guesswork out of watering and is especially helpful for Monstera owners prone to overwatering out of love.
Takes the guesswork out of watering so you can avoid both underwatering stress and root-rot-causing overwatering.

If your Monstera sits near a south-facing window with direct sun hitting the leaves for hours, curling can be a heat-stress response rather than a watering issue. Direct, intense light causes rapid transpiration, and the plant curls its leaves to reduce exposed surface area and conserve moisture — similar to underwatering symptoms, but the cause is light intensity rather than soil dryness.
Look for other clues: bleached or crispy patches, leaves facing away from the window, or curling that's worse on the sun-facing side of the plant. The fix is usually simple — move the plant a few feet back from the window or add a sheer curtain to diffuse the light. Monsteras thrive in bright, indirect light, not harsh direct rays. For a refresher on matching light levels to your space, check our guide on how much light houseplants need.
Heat from nearby radiators, vents, or sunny glass can compound the problem, so also consider the plant's proximity to these heat sources, not just light intensity.
Cause 4: Nutrient Deficiency or Low Light
Sometimes curling shows up alongside pale, small, or slow-growing new leaves rather than crispy edges. This pattern often points to insufficient light or a nutrient shortfall, particularly nitrogen or potassium. In low light, Monsteras can't photosynthesize efficiently, which stresses the whole plant and affects leaf development, including unusual curling in new growth.
If your plant hasn't been fertilized in a while, especially during the active growing season (spring through early fall), it may be running low on nutrients. Feed with a balanced, diluted liquid fertilizer every 4-6 weeks during the growing season — more isn't better here, as over-fertilizing can burn roots and worsen leaf problems. Our houseplant fertilizer guide covers dosing and timing in more detail.
If light is the issue, aim for bright, indirect light for at least 6 hours a day. A spot a few feet from an east or west-facing window, or a filtered south window, usually works well.
Frequently Asked Questions
Is it normal for new Monstera leaves to emerge curled?
Yes — new Monstera leaves naturally emerge rolled up like a cigar and unfurl over several days to a week. This is a normal part of growth, not a stress symptom, as long as the leaf eventually opens fully.
Will curled Monstera leaves uncurl on their own?
Mature leaves that have curled due to stress generally won't flatten back out completely, but new growth should emerge normally once the underlying issue is fixed. Focus on correcting watering, light, or humidity rather than waiting for old leaves to recover.
