Noticing your Monstera leaves curling can be concerning for any plant parent. These tropical beauties are known for their stunning fenestrated leaves, but when those leaves start to curl inwards or downwards, it’s a clear sign your plant is trying to tell you something. Curling leaves are your Monstera’s defense mechanism – a way to reduce surface area and minimize water loss when facing stress. Whether it’s improper watering, low humidity, or pest problems, identifying the specific cause is the first step toward helping your plant recover.
In this guide, we’ll explore the six most common reasons for Monstera leaves curling and provide actionable solutions to restore your plant to its full, lush glory.
Understanding What Your Curling Leaves Are Telling You
Before diving into solutions, it helps to understand what different types of leaf curling indicate. The direction of the curl often provides valuable clues about what’s troubling your plant.
Different types of Monstera leaf curling and what they indicate
Leaves Curling Inwards
When your Monstera leaves curl inwards or upwards toward the top of the leaf, it typically indicates a hydration issue. The plant cells are losing moisture and structure, causing the leaf to curl in on itself as it tries to conserve water. Common causes include:
- Underwatering
- Low humidity
- Root problems limiting water uptake
Leaves Curling Downwards
When your Monstera leaves curl downwards or droop, it usually signals stress from environmental factors or nutrient issues. The cells lose internal pressure, and the leaves cannot maintain their natural shape. Common causes include:
- Heat stress
- Excessive direct sunlight
- Nutrient deficiencies
Tip 1: Fix Watering Issues
Improper watering is the most common cause of curling Monstera leaves. Both underwatering and overwatering can lead to this problem, though they affect the plant in different ways.
Using a moisture meter helps determine if your Monstera needs water
The Problem
Underwatering
When your Monstera doesn’t receive enough water, the cells in the leaves begin to dry out and lose their structure. This causes the leaves to curl inward as a way to conserve moisture. You might also notice:
- Dry, crispy leaf edges
- Soil pulling away from the sides of the pot
- Drooping leaves
Overwatering
Overwatering leads to waterlogged soil that suffocates the roots, preventing them from absorbing nutrients and water properly. This can cause:
- Yellowing leaves that also curl
- Soft, mushy stems near the soil
- Root rot (roots appear brown and mushy instead of white and firm)
The Solution
- Check soil moisture before watering. Insert your finger 2-3 inches into the soil – if it feels dry, it’s time to water.
- Water thoroughly until water flows from the drainage holes, then allow excess water to drain completely.
- Allow the top 1-2 inches of soil to dry out between waterings.
- Adjust your watering schedule seasonally – water more frequently in summer and less in winter.
Pro Tip: Get a Reliable Moisture Meter
Take the guesswork out of watering with a soil moisture meter. These affordable tools provide accurate readings of soil moisture levels, helping you water at exactly the right time.
Tip 2: Increase Humidity Levels
As tropical plants, Monsteras naturally thrive in humid environments. In their native rainforest habitats, humidity levels often exceed 60%. When grown indoors in drier conditions, Monstera leaves may curl as the plant tries to reduce moisture loss through its foliage.
A humidifier can significantly improve conditions for your Monstera
The Problem
Low humidity causes excessive transpiration (water loss through leaves), leading to curling as the plant tries to conserve moisture. This is especially common in:
- Winter months when indoor heating dries the air
- Air-conditioned spaces
- Naturally arid climates
The Solution
Misting
Lightly mist your Monstera’s leaves every 1-2 days using room temperature water. While this provides temporary humidity, it needs to be done consistently.
Humidity Tray
Place your plant on a tray filled with pebbles and water. As the water evaporates, it creates a humid microclimate around your plant.
Humidifier
The most effective solution is using a plant humidifier near your Monstera. Aim to maintain humidity levels between 40-60%.

Maintain Perfect Humidity
A quality plant humidifier with adjustable settings will keep your Monstera and other tropical plants thriving year-round.
Tip 3: Adjust Light Exposure
While Monsteras need bright light to thrive, too much direct sunlight can cause stress that leads to curling leaves. In their natural habitat, these plants grow under the canopy of larger trees, receiving dappled, indirect light.
Ideal light placement: bright indirect light filtered through a sheer curtain
The Problem
Excessive direct sunlight causes several issues that lead to leaf curling:
- Increased water evaporation from leaves
- Leaf scorch and sunburn
- Heat stress that reduces cell turgor pressure
The Solution
- Position your Monstera where it receives bright, indirect light for 6-8 hours daily.
- If near a south or west-facing window, place the plant 3-5 feet away from the window or use sheer curtains to filter the light.
- Rotate your plant quarterly to ensure even growth and prevent it from leaning toward the light source.
- Monitor for signs of both too much light (curling, yellowing, brown spots) and too little light (slow growth, smaller leaves, fewer fenestrations).
Light Meter Tip: If you’re unsure about light levels, consider using a light meter app on your smartphone. Monsteras prefer light levels between 10,000-20,000 lux during the day.
Tip 4: Address Nutrient Deficiencies
Proper nutrition is essential for healthy Monstera growth. When essential nutrients are lacking, Monstera leaves may curl as the plant struggles to maintain normal cellular functions.
Regular fertilization helps prevent nutrient deficiencies in Monstera plants
The Problem
Monsteras require several key nutrients to maintain healthy growth. Deficiencies in these nutrients can cause specific symptoms:
| Nutrient | Role | Deficiency Symptoms |
| Nitrogen | Leaf growth, chlorophyll production | Yellowing of older leaves, stunted growth, leaves curling inward |
| Phosphorus | Energy transfer, root development | Dark green leaves that curl under, purplish stems |
| Potassium | Water regulation, enzyme activation | Yellow leaf edges, brown spots, leaves curling downward |
| Calcium | Cell wall structure | Distorted new growth, leaf tip curling |
The Solution
- Use a balanced liquid fertilizer (NPK 20-20-20 or similar) diluted to half the recommended strength.
- Fertilize your Monstera every 4-6 weeks during the growing season (spring and summer).
- Reduce fertilization to once every 8-12 weeks during fall and winter when growth slows.
- Flush the soil thoroughly every 3-4 months to prevent salt buildup from fertilizers.
Nourish Your Monstera
Give your Monstera the perfect balance of nutrients with a specially formulated houseplant fertilizer that promotes lush growth and prevents leaf curling.
Tip 5: Improve Soil Conditions and Repot When Needed
Poor soil conditions can significantly contribute to Monstera leaves curling. Over time, soil breaks down, becomes compacted, and loses its ability to properly drain and hold nutrients.
Repotting with fresh, well-draining soil helps prevent root problems
The Problem
Several soil-related issues can cause Monstera leaves to curl:
- Compacted soil restricts oxygen to the roots and prevents proper water absorption
- Poor drainage leads to waterlogged conditions and potential root rot
- Depleted nutrients in old soil cannot support healthy growth
- Root-bound plants with circling roots cannot effectively take up water and nutrients
The Solution
- Repot your Monstera every 1-2 years, preferably in spring when growth is active.
- Choose a pot 2-3 inches larger in diameter than the current one with ample drainage holes.
- Use a well-draining soil mix: combine 2 parts quality potting soil, 1 part orchid bark, and 1 part perlite.
- Gently loosen bound roots before placing in fresh soil to encourage outward growth.
- Between repottings, aerate compacted soil by gently poking it with a chopstick or similar tool.

Tip 6: Identify and Treat Pest Infestations
Pests can be a hidden cause of Monstera leaves curling. These tiny invaders suck the sap from your plant’s leaves, causing moisture loss and stress that results in curling foliage.
Spider mites are tiny pests that can cause significant damage to Monstera plants
The Problem
Several pests commonly affect Monstera plants:
Spider Mites
Tiny arachnids that leave fine webbing and cause stippling on leaves. They thrive in dry conditions.
Thrips
Slender insects that cause silvery patches and black specks (their droppings) on leaves.
Aphids
Small, pear-shaped insects that cluster on new growth and leave sticky honeydew behind.
The Solution
- Isolate the affected plant immediately to prevent spreading to other houseplants.
- Rinse the plant thoroughly with lukewarm water, focusing on the undersides of leaves where pests hide.
- Treat with insecticidal soap or neem oil solution, applying weekly for at least 3-4 weeks.
- For severe infestations, consider systemic insecticides that work from within the plant.
- Increase humidity around the plant, as many pests (especially spider mites) prefer dry conditions.
Regular treatment with neem oil can help prevent and treat pest infestations

Keep your Monstera pest-free with organic neem oil – a natural solution that’s safe for your plants and home.
Frequently Asked Questions About Monstera Leaves Curling
Can curled Monstera leaves recover?
Yes, in most cases curled leaves can recover if you address the underlying issue quickly. Newer leaves are more likely to return to normal than older, severely damaged leaves. Very crispy or brown curled leaves may not recover fully, but new growth should be healthy once the problem is fixed.
How long does it take for curled Monstera leaves to uncurl?
Recovery time varies depending on the severity of the issue and how quickly you address it. Minor curling from underwatering might improve within 1-3 days after proper watering. More severe problems like nutrient deficiencies or pest damage may take 2-4 weeks to show improvement as the plant recovers and produces new growth.
Should I cut off curled Monstera leaves?
Only remove leaves that are severely damaged, crispy, or brown. Leaves that are just curling but still green are still photosynthesizing and providing energy to your plant. Focus on fixing the underlying issue rather than removing leaves unless they’re clearly dead or diseased.
Why are my new Monstera leaves curling?
New Monstera leaves naturally emerge in a curled position and gradually unfurl as they mature. This is normal and can take 1-2 weeks. However, if new leaves remain tightly curled or curl after initially unfurling, this indicates a problem with growing conditions that needs addressing.
Revive Your Monstera with Proper Care
Curling leaves on your Monstera don’t have to be a cause for panic. By systematically addressing each potential cause – from watering habits to humidity levels, light exposure, nutrition, soil conditions, and pest control – you can restore your plant to its full, tropical glory. Remember that consistency is key when it comes to plant care, and small adjustments can make a significant difference in your Monstera’s health.
With the right care routine in place, you’ll not only fix your current leaf curling issues but also prevent future problems, allowing your Monstera to thrive with those beautiful, fenestrated leaves that make it such a beloved houseplant.
