Does Monstera Like Humidity?

Last Updated on August 4, 2022 by Stephanie

Monsteras are well-known for their huge leaves that have attractive splits and holes.

It was previously used as an a great addition to garden beds in the backyard. However, in recent times, this climbing vine is now popular being used as a houseplant.

In general, all varieties of Monstera arent difficult to cultivate inside. However, they can be somewhat picky about the humidity of their surroundings.

Monstera likes to be in humid conditions in which it is ideally able to enjoy an average humidity of 40% and 60 percent. It is not possible in certain areas, so testing the level of humidity and implementing the right humidity levels is crucial for the growth of Monstera.

How Does Humidity Affect Monstera

Monstera is a tropical plant where humidity levels are greater than what you are used to at home. This is why it is essential to replicate the environment of Monstera to provide the conditions for growth that allow it to flourish.

Apart from it being true that Monstera is naturally a fan of humid environments The most compelling reason why your plant is attracted to humidity is because it helps keep the water levels in check during photosynthesis.

If Monstera isnt receiving sufficient water supply, the stomata could shut. If this happens carbon dioxide is blocked, and photosynthesis will cease.

Because Monstera is a large-leaf plant, it needs an enormous quantity of intake, which can be achieved by ensuring that you regularly meet its water requirements.

The most effective way to help Monsteras watering requirements Monstera is to place it in a moist environment.

How Much Humidity Does Monstera Need

Monstera is usually at its best when there are the humidity of 60% or more. However, your home may not be as humid.

Dont worry, Monstera will still survive even if the humidity is reduced to 40%..

It is also recommended to keep your room at 60-80degF (15 to 26 degC) in conjunction with the optimal humidity level.

How to Measure Humidity in Your Home

If youre unsure whether your Monstera isnt getting the proper humidity, then you have to determine the humidity of your home.

Here are a few methods you can check the humidity levels of your home.

Ice Cube Testing

This method doesnt provide any precise measurement or level of humidity. However, it is a reliable method of determining whether your home is dry or humid.

Follow these easy steps when conducting ice cube test.

  • Make an ice cube and a glass of water. Ice cubes.
  • You must go to the area or room where youd like to take the test. This is technically the area where you develop your Monstera.
  • Place up to five or four cubes of ice in your glass, and place the glass on the table in the room.
  • Let it sit for 5 to 10 minutes.
  • When the time is up Check the glass. If you notice a lot of water forming outside the glass, it means that its likely that the humidity relative is very high. If there are only a few or no evidence of moisture, then the air is dry.
  • This is merely an ideal method to begin testing. If you are looking for exact results, you should buy a humidity tester from the nearest hardware store or.

Hygrometer Testing

A hygrometer is a test instrument that determines the levels of humidity in an environment. The scientific basis behind this instrument is simply measuring the quantity of vapor that exists in the surrounding.

The majority of hygrometers come with built-in thermometers as temperature can affect the level of humidity. Go here to purchase one.

To provide you with a greater understanding of how to use the hygrometer, I have gave a step-by-step guide on how to utilize it.

  • When youre installing a wall mounted hygrometer, choose a suitable spot in which you can put it. It is best to place it in the middle part of the room so that it will cover the entire area.
  • Switch on the meter and then wait for a few minutes for the instrument to be calibrated.
  • The meter should be set to the desired humidity level and choose the units you prefer to show.
  • Record the reading and monitor it every one or two hours. Note the minimum and maximum percentage readings youll get.
  • Check that the hygrometer is properly mounted to prevent injuries and damages.

There is the option to carry either a wall-mounted or hand-carry hygrometer. There is no distinction between the two kinds in regards to their use. They differ only in how youll use them.

A wall-mounted hygrometer can be employed to monitor the humidity levels of a specific space from time to time.

Then, a hand-carry hygrometer can be used for checking the minimum and maximum relative humidity levels for large regions.

It could be an ideal idea to install an hygrometer that is mounted on the wall if you are trying to determine if your Monstera gets the proper humidity at times.

Helping Monstera to deal with high humidity

While Monstera likes places with high humidity, excessive amounts of it could cause your plant to be vulnerable to infections that can cause pathogens. This is usually the case during winter months.

If you discover that your home is getting too humid, apply the following methods to decrease humidity.

Avoid Excessive Watering

If the humidity begins to increase over the acceptable range for your Monstera plant, it is necessary to reduce the frequency of watering. Although your plant is a lover of humidity but too much humidity can cause excessive water, which will eventually encourage the growth of fungi that infest the roots of your plant.

If humidity is increasing the amount of water you give your plant once every 10 days during summer and stop watering in winter.

It is also possible to check the drainage system of your pot to make sure theres no water accumulation happening beneath.

Improve Indoor Air Circulation

Here are some suggestions for providing good indoor circulation of air for your Monstera and other houseplants.

  • Do not place your plants too close to the walls. Leave a space between the wall to ensure that air circulation can be facilitated across the entire area of your plants.
  • Set aside up to six inches of space among your plants.
  • Make use of an air-conditioner to let air circulate across the space. This will keep moisture from accumulating on the leaves. Its not recommended to put your fan directly on plants. Keep a distance of at least one or two meters.
  • If you can, put in an exhaust system in the space. This can improve the circulation of air by getting rid of old air, allow new air as well as carbon dioxide circulate frequently.

Place your Monstera near the window

The placement of your Monstera close to the window will prevent it to a sufficient quantity of sun. This helps the plant reduce the amount of moisture it receives from its surroundings.

In addition to getting sunlight, the areas surrounding the window are surrounded by air that prevents an excessively humid environment.

Monsteras prefer direct sunlight that is bright, so the placement of it inside a window facing south is a great option. If you find it is getting too much light is too excessive for the plant, you can try placing it in an alternative window or using blinds to block the entrance of sunlight.

It appears that this technique isnt effective in winter. Actually, you must take your Monstera off of the window panes because cold temperatures could result in excessive water to the leaves of your plant.

Use the Right Type of Soil

In general, a well-drained, well-aerating and moisture retention type of potters mix is the best for Monstera to flourish. It is also a great mix for potting to help the plant in times of high humidity.

It is recommended to mix the perlite with orchid bark, coco chips, coarse sand, and perlite into a peat-based potting mix. This way, it will be able to hold a small amount of moisture , while also providing a well-draining and excellent aerating capabilities simultaneously.

You can also include compost in order to increase the organic quality and make it more nutritious.

Grow Lights for Monstera

If you provide a sufficient amount of sunshine the transpiration of humidity and plants will likely to reduce. But, this may not be achieved in the absence of an ideal spot to get sunlight , or in the winter months. This is where the lights can help.

When using grow lights, you must at a minimum match the hue of the sun and strive at low-medium lighting levels. Minimum 75-200 feet candles.

Take a look at our grow light bulb as well as the LED Grow Lights for top-quality grow light alternatives.

Signs Your Monstera Needs More Humidity

If you think your Monstera needs more humidity, youll notice the following.

  • The leaves then become tough and break easily. Because Monstera is a plant that loves water it will absorb more water than youve provided. In the end, the leaves turn dry as a sign of a water shortage.
  • If you look further youll also notice some wilting and drooping leaves.

All of these are signs that your plant isnt getting enough water intake, and you may want to determine whether youre giving your plant with the frequency of watering that it requires.

Methods for Improving Humidity Levels

If your home isnt able to provide the humidity levels that Monstera requires Dont give up just yet. There are still ways you can use to assist your plant in achieving the required humidity.

Grouping Plants

In their own way, plants release water through their leaves. This process is known as transpiration. So, placing your plants near to one another can make a humid atmosphere. You can group the Monstera together or mix the plant with houseplants that need high humidity.

Gravel Trays

This is a great method to boost the humidity within your plant.

Heres how to accomplish it.

  • With a clean tray, make sure to fill it with gravels or pebbles that are at least one inch in height.
  • Place water in the tray to at least half the height of the pebbles or gravels.
  • Set your pot on top of the gravel, making sure that it doesnt directly into the water.
  • Make sure to regularly clean the tray to prevent the growth of pathogens.

Use Humidifier

This method doesnt require any additional explanation. Simply put a humidifier around five to four feet from the plants. This will boost the humidity in the space, which is essential to allow Monstera to flourish.

Indoor Greenhouse

If the method you tried before isnt working, consider purchasing an indoor planter to your Monstera. Make sure you are aware of the size of your space prior to purchasing one.

Go here to purchase an Indoor Greenhouse on Amazon!

In general, a greenhouse is humid because that the inside air is hot. The more humid the air, there is more water it will retain.

The plants are also tightly joined inside a greenhouse enclosure which means that they produce and maintain humidity is ideal within.

Install your greenhouse next to an east-facing window so that it will receive a sufficient amount of sun.

It is also possible to add grow lights in case your home isnt able to receive light.


As humidity is essential to allow your Monstera to flourish You might think about misting as a great option to test. But, I strongly disagree with the use of this method due to obvious reasons.

If you live in a humid area, misting could result in excessive moisture on the leaves of your plants, which could cause pathogenic infections.

If youre in a humid area, misting may aid a bit but it wont suffice. Therefore, youll need to spray the Monstera each 15 mins in order to attain the desired humidity. Thats tedious, isnt it?

So, its recommended to find other methods to solve the problem, for instance using those previously mentioned methods earlier.

Final Words

In the end, Monstera definitely loves to be in humid conditions. But, it is important to establish boundaries so that it can remain within its optimal range. Here are a few tips you should keep in mind regarding the humidity levels of Monstera:

  • Be sure that the humidity level does not fall below 40%.
  • Utilize a hygrometer for a precise determine the level of humidity in the room.
  • Try using humidifiers, gravel trays, indoor greenhouses, or ways to group the humidity of your home.
