Do Philodendrons Like Humidity? Effects and Recommendations

The Philodendron is a popular houseplant due to their beautiful appearance and mild tolerance to situations that aren’t perfect.

When it comes to humidity levels, the plants can be tolerant of a variety of moisture levels, however they will flourish when you maintain them in the optimal conditions.

It’s surprisingly simple to accomplish if you change a few things to the way you take care of your plants.

The majority of homes are maintained in humidity levels that are just below the ideal conditions for Philodendron. However, it is possible to increase the humidity level in the area of your plants.

Philodendrons can tolerate a broad variety of levels of humidity. However, as you’ll see it’s also simple to increase or decrease the humidity to ensure that you can grow your plants in the best conditions. This will ensure that your Philodendron producing at its best and producing more flowers as well as healthier leaves.

What is the effect of humidity on the Philodendron?

In the ideal humidity Philodendrons absorb nutrients by absorbing them in a dissolvable shape through its roots, and then releasing the excess moisture through pores-like spaces, referred to as stomata , which are located on the underside on the leaf.

If the process is disrupted due to either excessive humidity or not enough humidity, it can impact the general health of the plant.

When the levels of humidity are too low, the plant will begin to show symptoms of stress. The rate of transpiration increases, and the plant is unable to take in enough nutrients.

The first thing you’re likely to notice is the brown tips of the leaves, followed by the margins of the leaves becoming yellow. As the issue becomes more pronounced, both the leaves and flowers begin to shrink and become dry.

When the humidity levels are excessively high, the rate of respiration is decreased because the plant is holding excessive water.

What you’ll begin to notice is a gray-colored mold that appears on the leaves, and then on the flowers themselves. The stems and leaves eventually begin to rot when the issue isn’t taken care of.

How to Measure Humidity in Your Home?

I have to admit that for a long time I didn’t really check the humidity levels in my home. My plants appeared to be doing well so I believed that I was having the humidity just exactly.

My plant collection was beginning to expand and became more important a part of my décor I was able to see that it would be beneficial to take an approach that is more scientific to this issue.

It was also clear to me that I was now quite deeply invested in my houseplants, so it was sensible to take care of the health of my plants.

Nowadays, it is possible to buy digital hygrometers at a fraction of the cost amount of money. These tiny and affordable instruments measure temperature as well as humidity with an impressive level of precision.

The majority of suppliers say that they’ll be out by 1 to 3 percent. Since they are cheap they are easy for me to have some scattered around the plants that comprise the indoor gardens I have.

How Much Humidity Does the Philodendron Need?

They are native to tropical rainforests and they require a high level of humidity.

Between 65 to 80 percent is a great target however, that can be lowered to 55 percent over the course of the night.

The majority of homes have humidity levels which range from 40 to 60 percent. The plants can tolerate this, but I prefer to bring my plants in their natural levels to ensure that they reward me with the highest growth and flower production.

Due to this, there is an extreme difference in the way plants work in regards to humidity. As for what the homeowner prefers it is simple to understand the possibility of problems developing.

How to Use a Humidity Meter?

Hygrometers that are digital are very simple to use since all you have to do is to switch them on.

It is important to note that it takes about two hours for them to adapt to their surroundings and begin giving precise readings. I have several of them in my planters and another further away from the room.

This provides me with a general view of the humidity surrounding the plants as well being a general view of the humidity levels in the room itself.

If there is a significant distinction between the area the area where they are taking their roots and the rest of the room, I am aware that I’ll soon have to take the appropriate steps.

The low humidity throughout the space, like is likely to translate into lower levels of humidity around the plants. Both environments aren’t completely distinct from one another.

Aiding Philodendron to deal with high humidity

If you can see on your hygrometer that the humidity is increasing, you’ll need to make changes that reduce the amount of moisture in the air.

If you don’t own an hygrometer, and you begin to notice signs of mold on the plant or the surface of the soil in which it is potting, you must adhere to these steps also.

Avoid Excess Watering

A large portion of the moisture that is that is in the atmosphere around your philodendron is likely to result from the moisture present in the soil of the potting and released by the plant during the process of transpiration.

Letting your philodendron dry slightly between waterings will lessen the amount of water needed.

The Philodendron will also be grateful to you for the reduction in excess water around its roots.

It is possible to get an precise measurement of how moist the soil in your potting pot is by poking your finger in the top 2 inches. Do not water until you sense that it is completely dry to the point of.

There isn’t a precise time date for when this will occur since it will depend on the temperature, transpiration speed and the retention of water in the soil. Regularly checking the soil is the only sure-fire method.

Improve Indoor Circulation

If the air inside the room is stagnant, it creates perfect conditions for the growth in humidity levels.

It’s not just harmful to the philodendron itself, it’s not very healthy for your health either. This issue can be fixed by simply opening a window or two for a few hours every day.

The improved circulation will eventually reduce the humidity within the room. Additionally, having doors at every end of the room allows air circulation to flow more freely.

Place Your Plant Near a Window

The air surrounding the window is typically the air most likely to move and thus less susceptible to become excessively humid.

Philodendrons do not like direct sunlight , so pick windowsills that provide plenty of light, however, not too much sunlight otherwise your plant could be burned.

If the temperatures outside are hot and the windows are open for a short time can reduce the humidity around the Philodendron.

Choose an Appropriate Potting Soil

It’s at first that the notion that potting soil can boost humidity may seem absurd. If you consider it but you will realise that potting soil that is damp is likely to be one of the areas that are most water-retentive within your home.

Philodendrons aren’t fond of having their feet wet, therefore, even if the humidity is not excessively high it is recommended to choose a medium for potting.

Mixing a great garden potting soil and 50 percent of perlite. The water will evaporate quickly, while providing an adequate amount of moisture for your plant.

Be aware that the presence of high amounts of coconut fiber or peat will improve the retention of moisture in the soil for potting.

Grow Lights

If you provide the proper quantity of sunlight, you can reduce humidity, speed up transpiration, and boost the growth of your plants. Ideally, Philodendrons prefer to get around eight hours of light and brightness every day.

In certain areas there is an adequate amount of sunlight. In dark rooms or areas that have long, harsh winters the requirements for lighting aren’t always fulfilled. This is where grow lights really become a part of the picture.

Choosing Grow Lights

The standard lighting fixtures don’t provide a wide enough range of light to meet all needs for healthy plant growth. Plants, unlike humans, require light to generate energy.

Philodendrons without light develop less efficiently and transpire less efficiently and thus encourage the increase in humidity. Lights that are effective can help address this issue.

  • Grow lights must be turned on for between eight and 10 hours per day.
  • Select a light with low energy.
  • LED white lights are the best choice.
  • Set them up directly over your plants.
  • Do not let the light sources be in contact with the foliage since it could cause burning to the leaves.
  • Combine them with a timer to maximize efficiency.

In the end Grow lights aren’t always necessary. It could be that your plants receive enough sunlight from the sun or you just need to think about their usage during the winter months when it is colder.

Signs Your Philodendron Needs More Humidity

Although the danger of excessive humidity is real, inside your home, it’s much less likely for low humidity to be more of a problem as compared to high humidity.

This is due to the fact that most of us reside in homes where humidity levels are somewhere between 40 and 60 percent.

The majority of Philodendrons can tolerate this less than average moisture level in the air, but be unable to thrive as well as they could do.

There are several reasons why you might need to increase the amount of humidity. The primary reason is that the plant’s performance will increase with increased humidity.

The other is that lower humidity can bring along with it specific health hazards like brown tips on the leaves crisp leaves, yellowing of the margins of the leaves.

If your plant isn’t showing any of these signs it is still cultivating in the same humidity that you have already provided.

Methods of Improving Low Humidity

Grouping Plants Together

It is a straightforward yet effective method to increase the humidity within the vicinity of the species or the island. The combination of their respiration releases water in the air, which creates a microclimate which is less dry.

Gravel Trays

Another trick that is simple to master is to place the Philodendron on a tray of gravel. Place a tray or saucer with pebbles or gravel and then add enough water to completely cover the plant you’ve selected.

When you put your potted plant back into the saucer, it’s sitting over, but not within, the water. When the water evaporates the humidity rises, but without the danger that the roots getting waterlogged.


The devices boost the humidity of the air. There are two options to choose from. One is to heat the water, and then releases it as steam, while the second stirs the water, releasing it in the form of mist.

By placing them within the vicinity of your Philodendron, you can alter the level of humidity according to your specific requirements.

It’s not always the best choice when you have only just one or two plants which could change if you decide to expand your collection.

Indoor Greenhouses

Mini greenhouses can be very useful, particularly when you have a huge space and are struggling to regulate the humidity levels.

In essence, they basically mini-greenhouses you can put in your home. They are made of transparent plastic or glass and typically can hold up to a dozen plants.

The less secluded environment the plants create is far simpler to create ideal growth conditions, both in terms of the temperature and humidity.


For a long time, the most popular method for increasing humidity was to spray the leaves of the plant a gentle spray of water using the squeeze bottle.

The moisture would then settle on the leaves, and the humidity would rise when it evaporated.

Recent research has altered how we view this method of practice. The new research suggests is the fact that humidity is just briefly raised before returning to its initial level again.

As a result, wet leaves are more prone to things like mold and rot, which are normally associated with excessive humidity.

Temperature Control

Philodendrons thrive best in temperatures of Between 55 and 90 degrees F (12 32 degC – 12).

The humidity levels rise when the temperature of the air is higher, because the warmer air will hold larger amounts of water.

This rule isn’t completely established. For instance hot dry areas like deserts tend to have dryer air due to the lack of water available for this hot atmosphere to soak up.

In your home, warmer temperatures could mean more humidity, particularly when there is moisture that needs to absorb, such as from potting soil that is wet or your fish tank or the accumulation of water within the saucers for your plants.

It is important to be conscious of it and monitor your moisture meters frequently.

In contrast, during winter cold it is common to warm the space with fires or central heating. This creates an unwelcoming, warm and dry environment with low humidity.

The plants aren’t adapted to the changes in climate and you’ll need to keep an eye on the humidity levels all through the all the time.

Humidity Requirement of Philodendron Varieties

There are more than three hundred varieties of Philodendron. The majority of them comply with the specifications that I have listed in this article regarding temperature, humidity, and lighting requirements.

It is important to recognize there are more exotic varieties may be more demanding when it comes to what they require to live.

I would suggest starting with the most extensively cultivated varieties, of which there are many and only when you are able to comprehend the plants can you begin to experiment with more complex varieties.

The uncommon varieties are usually much more costly due to the fact that they are more demanding with their increasing demands.

A simple plant that is extremely tolerant and has a variety of options. These are the main aspects to consider regarding humidity

  • The ideal humidity range is between 65 and 80 percent.
  • Utilize a hygrometer for the best way to measure humidity.
  • Set up a routine for watering that will allow your plant’s soil to dry out between waterings.
  • Make sure to use a potting medium that is free draining.
  • Be aware of the signs to look for in the context of both low and high humidity.
  • Consider local weather for both humidity and light levels.
  • Think about equipment like the grow light, humidifiers, as well as indoor greenhouses.
  • Select a variety that is common to start the Philodendron adventure.

Keep in mind that the more closely you can replicate the natural environment of the plant the more happy the Philodendron is likely to be.

As a result it will also grow more quickly and produce more lush foliage, blooms and will be more resistant to diseases and pests.
