7 Causes of Monstera Leaves Curling

Find out the reason for your Monstera leaves curving or are they small leaves first examine the soil to see if it is too wet or dry.

It is important to check if your beast is receiving enough indirect light and the right amount of space to expand. Additionally, you should examine for indications of insects or diseases.

Anything that causes water loss or preventing plants from absorbing the required amount of water is the reason for the leaves of monstera to curl. To make it easier to understand, Ill go over every possible cause, and then the ways to address the issue and return your monstera back to its ideal form.

Monstera Leaves Curling Due to Underwatering

This is the main reason behind Monstera leaf curving. If your Monstera isnt receiving enough water to carry out the normal physiological process , it will notify you by curling the leaves. How can you know if it is due to an absence of water?

Check out the potting soil , if the topsoil isnt dry, then check for leaves becoming brown, crisp edges to the leaves, or tips that are brown.

If you have any of these indicators, its a guarantee that youre drowning your monster. Another method that is easy to implement is to feel the weight of the pot. when its dry, it will feel much more light.

If you submerge your monstera, it naturally defends itself to conserve water and live. It decreases the area for transpiration (through which plants lose the water) process by curving the leaves.

Solution to Underwatering Monstera

Take a look at the following suggestions to water an submerged Monstera and to keep your plant well-hydrated all year long:

  • To fix the moisture problem immediately, soak the soil in water for a couple of minutes and then let it rest until the water has drained completely.
  • In lieu of following a specific frequency instead, you should use an established routine to determine whether it requires a drink. As you water it, slowly increase the amount of water till it starts to flow through drain holes. Clean the tray as soon as it is empty. Make sure you soak the soil in water directly, instead of watering the leaves.
  • There are several methods to determine if your plant is thirsty prior to watering. Use your fingers or a wooden stick about 2 inches deep in the dirt.
  • If its dry and dries, the Monstera has a thirsty stomach! If its moist and appears with soil clumps its probably best to have a few more days.
  • You could also purchase an moisture gauge to ensure that youre not relying on your intuition.

Chemicals present in City Tap Water Can Cause Monstera Leaf Curling

If youre using tap water to make your monstera, you could be creating a problem that can cause a variety of problems, including wrinkled and curly leaves. You might be wondering how do you even make that happen and why its not possible! Heres how:

Water from the tap or city water is contaminated with fluoride and chlorine mixed into it. To kill germs in the water, these chemicals are added.

If youre drinking this water frequently, the chemical is likely to kill beneficial microbes that live in the soil. They are the monsteras ally because they aid in the decomposition of organic matter and help make nutrients available to the roots to take in.

If youre using tap water to treat your monstera on a regular basis and it accumulates salts and harm your root system. In the end, your monsteras biological function will be affected. It will result in curly leaves on your favourite monstera plant.

Solution to Tap Water Problem

If youve already caused the damage, you must follow these steps to correct the issue:

  • Since the soil has been contaminated with the chemicals of tap water, it is necessary to completely change the soil. Make sure you have a drainage capacity that is adequate for your soil.
  • Cut off the root damage and then plant them in the soil that you have created.
  • Make sure you use water that is filtered for your monstera.
  • If you are still planning to tap water, ensure that it is free of chlorine and other chemicals. Maintain the temperature at room temp and and let it rest for a night. Within 24 hours, the chlorine will disappear out of the water.
  • The melting snow or rainwater is another alternative for watering safely.

If youre using store-bought filters, make sure you change them on a regular basis. If you dont, youll be one of the elements that can harm your drinking water, instead of getting rid of them!

Monstera Leaves Curling Due to OverFertilization

This is a crucial thing to know for container-growing monstera. I believe that the doses of fertilizer listed on the packaging are more than needed.

This is why I suggest applying a balanced fertilizer each one week, at a half, or even less than recommended dosage. I am confident that it wont deplete your beasta.

The plant requires more nutrients while creating new buds and leaves. This is the stage of growth. In winter, you dont have to fertilize all of your plants, including monstera.

If youre being too generous, it could cause death to your monstera, and yes, over-fertilization could be fatal. If you fertilize too much, the roots get burned or damaged. You will notice signs such as curling of the foliage.

The problem is how do you determine if youre feeding your monstera hungry? You dont have to conduct any complicated laboratory test. Its simple to determine by looking around.

If you notice any white, crusty deposits around the edges in the containers or the soils surface then its a certain possibility that youve committed the wrong thing by overfeeding.

How to Fix Overfertilizing Issue

  • If youve identified the problem of overfertilization, then stop fertilizing.
  • Repotting is essential with a new soil mix.
  • Always remember that it is better to fertilize less than you overfertilize.

Monstera Leaves Curling Due to Overwatering

If, a week later, after youve watered the soil, it appears wet, its likely that youve overwatered. This could cause the water to swell and then suffocate the roots.

The water molecules are a part of those pores in the soil, which means there is no oxygen available to roots. This means that the Monstera isnt able to absorb nutrients and oxygen. This can cause …you probably guessed it…curling of the plants leaves.

Since stagnant water can be an ideal source of fungal infections like root rot. If your plant is affected by root rot, your root system wont function effectively to provide the necessary water and nutrients to other areas of the plant.

How to Fix Overwatering Problem

  • Be sure to water your plant when your plant is in need of water. Use the previously mentioned finger method to determine the level of moisture.
  • Utilize the alternate method of drying to water your beasta. The process of letting the soil dry between watering is known as the alternative drying method.
  • Make sure that the drainage holes are functioning correctly to drain any excess water.
  • In the event that your soil appears very hard and has poor drainage capacity, then you should consider using a high drainage soil.
  • Make the soil more loose through the addition of perlite, sand, vermiculite, mulch, or compost for better drainage capacity.

Monstera Leaves Curling Due to Temperature Stress

Rapid changes in temperature could cause leaves to curl. The temperature of the room should be between 65degF and 85degF (18degC-30degC) and should not be lower than 60 degrees (15degC). Monstera is an invasive tropical plant, and temperatures that are too cold can result in stress due to temperature.

MOsntera growth slows in low temperatures, but however, when temperatures rise, the process of physiological growth is speeded up and the plant attempts to cool itself by transpiring or shedding more water through its leaves.

This can result in the plants leaves curling to help conserve the water by reducing leafs exposure to heat and light sources.

How to fix the temperature stress Problem

  • Make sure to keep them from the vents for air conditioning, fireplaces and drafty doors or windows.
  • A lot or not enough exposure to light can damage the Monstera plant. The direct sunlight can actually cause burns to the leaves of the plant, causing them to curl upwards. The leaves tips can change color to brown.
  • The east-facing window is the most ideal location for the gianta plant to flourish. The plant can be battling heat waves in the summer months.

Fungal Diseases Can Cause Curling Leaves

The fungal infection occurs in the event of a moist situation or stagnant water in the pot. Insufficient or excessive drainage are the primary causes for this illness.

It can be difficult to recognize the illness at its earliest stage. When the soil appears sloppy or damp and leaves are curled, then it is possible to examine your root systems.

If you notice soft and brown roots, with an unpleasant smell emanating from them, you are most likely suffering from root rot. Healthy roots are usually solid and white.

How to Fix Root Rot

  • Remove the plant from the pot and wash the root system using tap water.
  • Remove the infected or rotten parts using a disinfected scissor.
  • Then let the plant air dry for a day.
  • Repot in an entirely new container, with fresh soil.

Insect Infestation

There are a few bugs that could be a threat to monsters and cause damage. However hard you try, its almost impossible to eliminate bugs completely. But, this article will offer solutions to common bugs.

Thrips, spider mites, Aphids are the most common sap-sucking insects that you might see in your garden. They suck the rich nutrients-rich sap from the leaves, resulting in curled leaves.

These insects are small in size, so you must be attentive to spot them and then take action. Find them on the upper and underneath of the leaves.

How to Eliminate Insects

I favor a non-chemical or organic method to get rid of pests on my the houseplants. Dishwashing liquid soap or rubbing alcohol, as well as Neem oil is a great option to fight these kinds of soft-bodied insects. If you have a large infestation, then you should consider chemical solutions.

Monstera Leaves Curling Due to Low Humidity

Monstera thrives on moderate levels of humidity in the room. Because it is a tropical plant, it cannot withstand low humidity. What happens when the humidity is not high?

You are already aware of the process of water release in plants called transpiration. If the humidity is low, your plant loses more water than usual, resulting in curled leaves.

You can determine the level of humidity with a hygrometer, or by forecasting the weather using your phone. While the humidity in a room will vary from the outside humidity but youll be able to get an idea.

Low humidity signs and underwatering signs are nearly identical. Utilizing a digital hygrometer can remove all confusion. The humidity level must be between 40% - 60 percent, if your homes humidity falls within the range, then humidity isnt the problem.

How can you help Monstera with Low Humidity

Here are a few strategies you can employ to boost the humidity of your monstera:

  • The most effective method is to make use of an humidifier.
  • Another method is to group all your plants is to increase the overall humidity. The humidity increases because of water vapor that is released from plants.
  • It is a Pebble tray is a different DIY way to boost the humidity of your huge. Simply place some pebbles on the tray, then pour water over it, then put the plant on top. You have pebble tray.
  • Many people suggest misting in order to boost humidity, but Im not a big fan of this technique. Misting may attract fungal growth on your monstera leaves.
  • Read this article about increasing humidity in monstera to find out more.

New Leaves

It is important to remember that the new leaves on monstera can curl, that is normal. The leaves will naturally fall off when it gets bigger.

Final Words

Low humidity are the two most frequent causes of curly leaves in monstera plants. Before you get into the details it is important to keep these two issues in your mind.
