Why Are My Monstera Leaves Curling

Your monstera leaves are curling because the plant is stressed by an environmental factor that’s throwing off its moisture balance.
 
When you notice monstera leaves curling, it’s almost always a cry for help related to water, humidity, light, or temperature.
 
The good news is that curling is usually reversible if you catch it early and adjust your care routine.
 
In this post, we’ll dig into why monstera leaves curl, how to fix each cause, and how to keep your plant happy long-term.
 
Let’s get your monstera back to its flat, glossy, and gorgeous self.
 

Why Are My Monstera Leaves Curling? The Main Culprits

The short answer to why your monstera leaves are curling is that the plant is losing water faster than it can take it up, or it’s being damaged by a sudden change in its environment.
 
When monstera leaves curl, they’re trying to reduce the surface area exposed to the air, which helps them conserve moisture.
 
Let’s break down the most common reasons so you can pinpoint the exact issue.
 

1. Underwatering Is the Most Common Trigger

If you’ve been asking why your monstera leaves are curling, underwatering should be your first suspect.
 
When the soil dries out completely, the roots can’t deliver enough water to the leaves.
 
The leaf cells lose turgor pressure, which is the internal water pressure that keeps them firm and flat.
 
As a result, your monstera leaves curl inward, often looking crispy or dry at the edges.
 
Check the top two inches of soil; if it’s bone dry and pulling away from the pot sides, your monstera is thirsty.
 
Give it a thorough soak until water runs out the drainage holes, and you should see improvement within a day or two.
 

2. Low Humidity Makes Monstera Leaves Curl

Monstera plants are native to tropical rainforests, where humidity hovers around 60–80%.
 
In our homes, especially during winter or in air-conditioned rooms, humidity can drop to 30% or less.
 
When the air is too dry, monstera leaves curl to minimize moisture loss through their pores.
 
You might also notice brown, crispy tips alongside the curling.
 
To fix this, mist your plant daily, place a humidifier nearby, or set the pot on a pebble tray filled with water.
 
Grouping your monstera with other plants can also create a microclimate with higher humidity.
 

3. Overwatering Can Also Cause Curling

It may seem counterintuitive, but overwatering is another answer to why your monstera leaves are curling.
 
When the roots sit in soggy soil, they can’t absorb oxygen, and root rot sets in.
 
Damaged roots can’t uptake water properly, so the leaves curl even though the soil is wet.
 
In this case, the curling is often accompanied by yellowing leaves, mushy stems, and a foul smell from the soil.
 
If you suspect overwatering, let the soil dry out completely before watering again.
 
You may also need to repot your monstera in fresh, well-draining soil and trim away any black, rotten roots.
 

4. Temperature Stress Makes Leaves Curl

Monstera leaves curling can also be a reaction to temperature extremes.
 
These tropical beauties prefer temperatures between 65°F and 85°F (18°C to 29°C).
 
If your monstera is near a drafty window, an air conditioning vent, or a heat source, it will curl its leaves as a protective response.
 
Cold drafts are especially problematic, as they can cause sudden water loss from the leaves.
 
Move your plant to a spot with stable, moderate temperatures, away from direct blasts of hot or cold air.
 

5. Too Much Direct Sunlight

While monstera loves bright, indirect light, direct afternoon sun can scorch the leaves.
 
When exposed to harsh rays, your monstera leaves curl up to shield themselves from excess light and heat.
 
You might also see bleached patches or brown, sunburned spots on the foliage.
 
If your plant sits in a south- or west-facing window, filter the light with sheer curtains or move it a few feet back.
 
The ideal spot is near an east-facing window or a few feet away from a bright, indirect light source.
 

How to Fix Curling Monstera Leaves Step by Step

Now that you know the why, let’s talk about the how to fix it.
 
The good news is that monstera leaves curling is rarely fatal, and most plants bounce back within a week of proper care.
 
Here’s a simple action plan to address the issue.
 

1. Assess the Soil Moisture First

Stick your finger about two inches into the soil.
 
If it feels dry, water your monstera deeply and thoroughly.
 
If it feels soggy, hold off on watering and let the top layer dry out.
 
A moisture meter can also give you a more accurate reading if you’re unsure.
 

2. Increase Humidity Around the Plant

A humidifier is the most effective way to boost moisture levels.
 
Alternatively, you can fill a shallow tray with pebbles and water, then place the pot on top (ensuring the bottom isn’t sitting in water).
 
Misting is helpful, but it only provides temporary relief, so pair it with a more permanent solution.
 

3. Check the Roots for Damage

If you’ve ruled out underwatering and low humidity, it’s time to inspect the roots.
 
Gently slide your monstera out of its pot and examine the root ball.
 
Healthy roots are white or light tan and firm, while rotten roots are brown, black, or mushy.
 
Trim away any damaged roots with clean scissors, then repot in fresh, well-draining soil.
 

4. Adjust Light and Temperature

Move your monstera to a spot with stable temperatures and indirect light.
 
Keep it away from heating vents, air conditioners, and drafty windows.
 
If the curling was caused by too much sun, the new leaves should come in flat and healthy once the plant acclimates.
 

So, Why Are My Monstera Leaves Curling?

So, why are your monstera leaves curling?
 
Your monstera leaves are curling because of an environmental stressor, most commonly underwatering, low humidity, overwatering, temperature extremes, or excessive direct sunlight.
 
Once you identify the exact cause and correct it, your plant will recover quickly.
 
Remember to check the soil moisture first, then adjust humidity, and finally rule out root or lighting issues.
 
With a little patience and observation, you can prevent monstera leaves from curling and keep your plant thriving for years to come.
 
Hope this guide helps you crack the case of the curling leaves and get your monstera back to its lush, joyful self.
 
Happy planting!
