ByRimon Chowdhury Updated on

There’s nothing quite like the sight of a magnificent, fenestrated Monstera leaf unfurling in your home. It’s a moment of pure plant parent pride! So, it’s completely understandable to feel a jolt of panic when you notice a once-perfect monstera leaf curled up and looking distressed.

But please, don’t worry! Take a deep breath. A curling leaf isn’t a death sentence; it’s your plant’s primary way of communicating with you. It’s sending an SOS signal, and with a little detective work, you can easily figure out what it needs.

I promise, by the end of this guide, you’ll feel confident in your ability to “speak Monstera.” We’ll walk through the most common reasons for curling leaves, from simple thirst to uninvited pests, and provide you with actionable, easy-to-follow steps to bring your green friend back to its glorious, thriving self.

Why Is My Monstera Leaf Curled Up? Decoding the Signals

Before we dive into solutions, it’s helpful to understand why a leaf curls. Think of it as a defense mechanism. When a Monstera is stressed, it curls its leaves to conserve moisture and protect itself from further harm, like excessive sun or pests. It’s a brilliant survival tactic!

The trick is figuring out what the specific stressor is. This is one of the most common problems with monstera leaf curled up issues, but the causes are usually straightforward. Most of the time, the culprit is one of five things:

  • Watering Issues (too much or too little)
  • Improper Light Exposure
  • Low Humidity or Temperature Stress

    • * Pesky Pests

  • Nutrient or Soil Problems

Let’s break down each of these possibilities in this complete monstera leaf curled up care guide so you can diagnose your plant like a pro.

The #1 Culprit: A Deep Dive into Watering Woes

In my experience, nine times out of ten, a curled Monstera leaf is pointing to a problem with water. Your plant is either desperately thirsty or drowning in kindness. Figuring out which one it is is your first and most important step.

Underwatering: The Thirsty Curl

This is often the easiest problem to identify and fix. When a Monstera is thirsty, its leaves will curl inward, almost like they’re cupping their hands to catch rain. The leaves might also feel limp, droopy, and the edges can start to look a bit crispy.

How to check:

The finger test is your best friend! Stick your index finger about two inches deep into the soil. If it comes out completely dry and clean, your plant is thirsty. You can also lift the pot; a dry pot will feel significantly lighter than a well-watered one.

The Solution:

Give your Monstera a thorough, deep drink. Don’t just splash a little water on top. Take it to a sink or bathtub and water it until you see liquid flowing freely from the drainage holes. This ensures the entire root ball is saturated. Let it drain completely before returning it to its saucer. Your plant should perk up and its leaves start to uncurl within 24 hours!

Overwatering: The Suffocating Curl

While it comes from a place of love, overwatering is far more dangerous than underwatering. When roots sit in soggy soil, they can’t access oxygen and begin to rot. A monstera leaf curled up from overwatering might also be accompanied by yellowing leaves (especially lower ones), soft brown or black spots, and a musty smell coming from the soil.

Again, use the finger test. If the soil is damp or soggy two inches down, even though you haven’t watered in a while, you may have an overwatering problem. Check the drainage holes to ensure they aren’t blocked.

The Solution:

If you catch it early, simply allow the soil to dry out completely before watering again. If you suspect root rot, you’ll need to act fast. Gently remove the plant from its pot and inspect the roots. Healthy roots are firm and white; rotten roots are brown, mushy, and may smell foul. Trim away any rotten parts with sterile scissors and repot the plant in fresh, well-draining soil.

Let There Be (the Right Kind of) Light

Monsteras love bright, indirect light. They hail from the jungle floor, where they receive dappled sunlight through the canopy. Replicating this is key to their happiness.

Too Much Direct Sun

If your Monstera is sitting in a window that gets blasted with direct afternoon sun, its leaves will curl to protect themselves from getting scorched. You’ll likely see sunburn spots (crispy, brown patches) or a bleached, washed-out color in addition to the curling.

The Solution: It’s simple—move your plant! A spot a few feet back from a south- or west-facing window is perfect. An east-facing window that gets gentle morning sun is also an excellent choice. Sheer curtains can also help diffuse harsh light.

Not Enough Light

While less common, insufficient light can also cause issues. The plant may not have the energy to support its large leaves, causing them to droop or curl slightly. You’ll also notice slow growth, smaller leaves, and a lack of the iconic splits (fenestrations).

The Solution: Move your Monstera to a brighter location. If you don’t have a naturally bright spot, don’t worry! These plants do wonderfully under a simple full-spectrum grow light.

Creating a Tropical Paradise: Humidity and Temperature

Remember, your Monstera is a tropical queen! It craves warmth and humidity. A dry, drafty environment is a common source of stress that can lead to curling leaves.

The Humidity Factor

Most homes have a humidity level around 30-40%, but Monsteras prefer it closer to 60%. When the air is too dry, moisture evaporates from their leaves too quickly, causing them to curl up and develop crispy brown edges.

Here are some easy monstera leaf curled up tips for boosting humidity:

  • Group Your Plants: Plants naturally release moisture through a process called transpiration. Grouping them together creates a wonderfully humid microclimate.
  • Use a Pebble Tray: Place a tray filled with pebbles and water underneath your plant’s pot. As the water evaporates, it will increase the ambient humidity. Just make sure the pot isn’t sitting in the water.
  • Invest in a Humidifier: This is the most effective way to control humidity, especially in dry winter months.
  • Misting: While it provides a temporary boost, misting isn’t a long-term solution and can sometimes encourage fungal issues if done improperly. It’s a nice treat, but not a substitute for consistent humidity.

Temperature Stress

Monsteras are not fans of sudden temperature fluctuations. Keep them away from drafty windows, doors, and air conditioning or heating vents. They are happiest in a stable environment between 65-85°F (18-29°C).

Uninvited Guests: A Guide to Common Monstera Pests

Sometimes, the cause of a curled leaf is a pest infestation. These tiny critters suck the sap from the leaves, causing them to deform, discolor, and curl. A regular inspection is one of the monstera leaf curled up best practices to catch them early.

Identifying and Treating Spider Mites

These are tiny arachnids that are almost impossible to see with the naked eye. The tell-tale sign is fine, delicate webbing on the undersides of leaves and where the leaf meets the stem. You may also see tiny white or brown dots (the mites themselves) and a stippled, discolored appearance on the leaves.

The Solution: Start with a gentle, sustainable monstera leaf curled up treatment. Take your plant to the shower and give it a good rinse to physically dislodge them. Follow up by spraying the entire plant—tops and bottoms of leaves—with a solution of insecticidal soap or neem oil.

Banishing Thrips

Thrips are tiny, black, winged insects that are a bit larger than spider mites. They cause significant damage, leaving behind silvery patches and tiny black specks (their excrement). New growth may emerge distorted and curled.

The Solution: Thrips are notoriously difficult to eliminate. Isolate the plant immediately. A thorough cleaning and repeated applications of neem oil or insecticidal soap every 5-7 days are necessary to break their life cycle. For severe infestations, a systemic insecticide may be required.

A Proactive Monstera Leaf Curled Up Guide: Prevention is Key

The best way to deal with a curled Monstera leaf is to prevent it from happening in the first place! Once you understand how to monstera leaf curled up issues arise, you can create a care routine that keeps your plant happy and resilient.

Here is your preventative checklist:

  1. Water Consistently: Don’t stick to a rigid schedule. Instead, check the soil every week and water thoroughly only when the top two inches are dry.
  2. Provide Bright, Indirect Light: The right light gives your plant the energy it needs to thrive. An east-facing window is often the sweet spot.
  3. Maintain Humidity: Group your plants or use a pebble tray. Your Monstera (and other tropicals) will thank you for it.
  4. Inspect Regularly: Once a week, take a close look at your plant. Check under the leaves and in the crevices for any signs of pests. Early detection is everything!
  5. Use Quality Soil: Plant your Monstera in a chunky, well-aerating aroid mix. This promotes healthy roots and helps prevent overwatering.

Frequently Asked Questions About Monstera Leaf Curling

Should I cut off a curled Monstera leaf?

Not necessarily! If the leaf is curled due to thirst, it will likely uncurl and recover after a good watering. However, if the leaf is yellow, heavily damaged by pests, or crispy brown, it won’t recover. In that case, it’s best to prune it off with clean shears so the plant can redirect its energy to new, healthy growth.

Why are my new Monstera leaves curled up and not unfurling?

This is usually normal! New leaves emerge tightly coiled and take time to unfurl. This process can be slowed by low humidity. If the leaf seems “stuck” for more than a couple of weeks, try increasing the humidity around the plant to help it along. Be patient and avoid trying to unroll it manually, as this can damage the delicate new growth.

Can a curled leaf uncurl itself?

Absolutely! The benefit of noticing a monstera leaf curled up early is that the damage is often reversible. Leaves curled from underwatering or minor temperature stress will typically flatten back out once the issue is corrected. Leaves that are physically damaged by pests or sunburn, however, will remain scarred.

Your Monstera is Talking—Are You Listening?

Seeing a curled leaf on your beloved Monstera can be alarming, but I hope this guide has shown you that it’s simply a form of communication. By methodically checking your plant’s water, light, environment, and health, you can quickly diagnose the problem and get it back on the road to recovery.

Remember to be patient with your plant, and with yourself. Every gardener learns through observation and experience. You’ve got this!

Happy growing!
