The different levels of humidity for houseplants

Humidity is the measure of water vapor in the air. The higher the humidity, the more moisture there is in the air. You can often feel the humidity in the air if you're in a warm, wet area. The air will feel heavy, sticky, and damp. Even breathing could be more difficult with very high levels of humidity.
On the other hand, you have very dry air. This will feel much lighter and it'll be quite easy to breathe. However, any moisture will also evaporate quickly, because the air can easily absorb it.
So what is the ideal range of humidity in the air for most houseplants? Somewhere in the middle! The ideal indoor humidity level for houseplants generally ranges from 40 to 60 percent relative humidity (RH). Some plants, like Ferns, even prefer higher levels like 80 percent. Relative humidity is a measure of how much water vapor is in the air compared to how much the air can hold. This sounds complicated, but luckily there are tools you can use to easily find the relative humidity in your living spaces.
Plants like succulents and cacti, on the other hand, prefer lower levels of humidity - around 30 - 40%. These lower humidity levels are perfect for these types of plants, as they natively grow in arid environments: places with very little rain and moisture.
What happens if the humidity levels are too low or too high for houseplants?
These humidity levels sound great, but do they matter for the health of your houseplants? Let's find out!
When the humidity levels are too low, your houseplants will lose water quickly, which can lead to signs of dehydration and stress. Your plants may start to lose their vibrant color, look wilted, or their leaves may droop down. If humidity levels are too high for your houseplants, they can suffer from root rot, mildew, and other diseases.
This is why it's important to keep an eye on the humidity levels of your houseplants and make sure that they are within the preferred range. Let's find out how we can make sure that our plants are and stay within these preferred humidity level ranges.
Signs of proper humidity levels
Creating a comfortable living environment for your plants goes beyond just watering and sunlight; humidity plays a crucial role in keeping them happy and thriving. Understanding the signs of proper humidity levels can help you create an oasis in your home where your green companions can flourish. From lush foliage to vibrant blooms, healthy plants provide clear indicators that they are content. Let’s dive into what you should look for and how to gauge if your humidity levels are just right.
When the humidity is ideal, healthy plants will exhibit vibrant, lush foliage. Look for leaves that are deep green and well-hydrated, without any browning tips or curling edges. Plants such as pothos, ferns, and peace lilies will often showcase full and robust growth when they are thriving in a humid environment.
You might also notice new leaves unfurling—a sure sign that your plants are feeling good! In addition to appearance, observe the overall vigor of the plant; if they seem to grow steadily and aren’t dropping leaves frequently, it’s a good indication that humidity levels are ideal for their health.
On the other hand, if your plants show signs of stress, it could be a signal that humidity levels aren’t quite right. For instance, if you notice leaf curling, browning tips, or dry, crispy edges on the leaves, these symptoms might point to low humidity levels. Excessive moisture may lead to issues like mold or mildew, especially if there’s a damp, musty smell.
Happy plants will display vibrant growth, while unhappy ones will send warning signs through their leaves. Keeping a close eye on these indicators will help you maintain a thriving indoor garden!
How to measure humidity levels in your home

Now you know the average humidity levels you should have in your house to give your plants a nice place to grow. But how do you know if your living spaces aren't too moist or dry for your plants? Let's find out!
There are many ways to measure relative humidity levels in your house. The most common method is using a hygrometer or thermometer with built-in humidity sensors. These tools will give you a precise reading of the relative humidity in your home.
A more simple, less precise way to find out if the humidity in the room is high is to look for water droplets on windows or wall tiles. If you can see water droplets, chances are that the air in that room is quite humid and could be a good place for a majority of your houseplants. However, this is not a foolproof way, as very well-insulated houses will probably not have any water droplets on the windows. This is also not a very precise method, but it will give you a good indication if the space is good for your plant or if it's too dry.
How to adjust humidity levels in your home

Once you know the humidity levels in your house, it's time to adjust them. This can be done with a humidifier or dehumidifier; both are great tools that allow you to control the moisture content in the air.
If you want to increase the humidity levels in your home, a humidifier is what you need. These devices release a fine mist of water into the air, increasing humidity levels and making it easier for your plants to absorb the moisture they need.
On the other hand, if you want to reduce the humidity in the house, then a dehumidifier is what you should use. This device will suck up excess water from the air, reducing humidity levels and making the environment better suited for plants that prefer lower humidity.
If you're looking for more low-tech ways to increase or decrease the humidity in your living spaces, there are several great ways. If you'd like to increase the humidity, you can place open jars or water around your plants, place your places on trays with pebbles and water, or simply place multiple plants close together. These plants will increase the humidity around them and this will benefit all plants in the group.
A great low-tech way to decrease the humidity in a room is to use "moisture absorbers". These are small packets and containers that contain large salt kernels. These kernels absorb the moisture in the air and melt in a container. They're a great low-cost way to reduce the humidity levels in a room and make it more comfortable for your houseplants.
Natural Ways to Increase Humidity
Maintaining the right humidity levels is essential for keeping your indoor plants happy and healthy. Fortunately, several simple and natural methods can help you boost humidity without needing complicated gadgets or equipment. Here’s a list of easy techniques that you can implement right away to create a more inviting environment for your plants.
Group plants together
Place your plants closer together to create a humid microclimate. When plants are close, they release moisture into the air, increasing the humidity for each other.
Use a pebble tray
Fill a shallow tray with pebbles and water, then place your potted plants on top. As the water evaporates, it will raise the humidity around the plants. Make sure the plants themselves aren't sitting in the water though, because this could lead to overwatering.
Misting leaves
Lightly mist the leaves of your plants with water using a spray bottle. This adds moisture directly to the foliage, which can help raise humidity temporarily.
Place containers of water nearby
Set small bowls or containers filled with water around your plants. As the water evaporates, it will increase the humidity in the surrounding air. It's very similar to pebble trays, but a little easier to do.
Use a humidifier
While this involves a little equipment, a simple room humidifier can raise humidity levels in your house really quickly, so you can help your plants thrive at a moment's notice.
Create a terrarium
Build a small terrarium with humidity-loving plants. The closed environment will help retain moisture and create a humid atmosphere.
Use your Bathroom or kitchen
Use the naturally humid areas of your home, like the bathroom or kitchen, for houseplants that thrive in high humidity. You won't have to give your plants any special care this way and they'll be happy anyway.
Run hot showers
Take advantage of steam from hot showers by leaving your bathroom door open for a while afterward. It's a great way to increase humidity for plants nearby!
How often should you check the humidity levels for your houseplants?

Now we know how to (approximately) measure the humidity levels in our house and how to adjust the levels to make the lives of our plants a little easier. But how often should you check the humidity?
There isn't a specific timeline that you should follow, but it's a good idea to check the humidity levels regularly to make sure they're still at the right levels. If you check the humidity levels once per week or once every 2 weeks, that's great. However, you can also wait until your plants start to show early signs of trouble. When your plants show any signs of being too humid or too dry, you now know how to help them be happy again.
Humidity and seasonal changes
As the seasons shift, so do the indoor humidity levels that can have a big effect on your plants’ health and happiness. Understanding how humidity changes throughout the year helps you to keep your plants thriving in any season. Let's look at how humidity varies by season and what you can do to keep your plants happy.
Spring
Humidity change: As temperatures start to rise, humidity levels tend to increase naturally, especially with the return of rain showers.
Tips: This is the perfect time to monitor your plants for new growth spurts. Make sure they're getting enough moisture without overwatering, as increased humidity can also lead to mold if the soil stays too damp.
Summer
Humidity change: Summer usually brings higher humidity levels due to temperatures, but in some areas, it can also get dry if you use air conditioning a lot.
Tips: Keep an eye on your plants to ensure they are not drying out. Misting can be beneficial during hot, dry spells, and using pebble trays can help maintain humidity levels. Regularly check the soil moisture to prevent stress on your plants.
Fall
Humidity change: As fall arrives, temperatures begin to drop, and humidity levels often decrease, especially if you begin to use heating systems.
Tips: Adjust your routine by moving plants closer together or using humidifiers to compensate for the dry air. Consider bringing tropical plants indoors if they're still outside, as they will need higher humidity levels during this transitional period.
Winter
Humidity change: Winter is notorious for low humidity levels, especially because of the heating systems that can dry out indoor air.
Tips: This is the time to be dedicated about raising indoor humidity. Use a humidifier, place water trays near your plants, and consider grouping plants together to create a more humid micro-environment. Regularly misting the leaves can provide additional moisture and help keep them happy.
Humidity levels and plant growth stages

Just like us, plants have different needs as they grow and develop. Humidity plays a huge role throughout a plant's lifecycle. Let's see how humidity needs vary from seedlings to mature plants and what you can do to support them along the way.
Seedlings
Humidity needs: Seedlings thrive in high humidity (around 60%-80%) to help support their soft leaves and roots as they establish themselves.
Tips: Use a humidity dome or cover to help maintain a warm, moist environment that encourages sprouting. Mist the soil lightly to keep it moist without overwatering, and place seedlings in a well-lit area to stimulate growth while protecting them from drafts that can dry out the air.
Young Plants
Humidity needs: As plants grow, their humidity needs decrease slightly, but they still benefit from moderate humidity levels (around 40%-60%).
Tips: During this stage, provide consistent moisture without letting the soil become soggy. You can remove humidity domes gradually while still misting the plants regularly. Grouping young plants together will help create a humid micro-environment that supports healthy growth.
Mature Plants
Humidity needs: Mature plants adapt to a wider range of humidity levels (30%-60%) but still appreciate consistent moisture to keep their leaves vibrant and healthy.
Tips: While mature plants can tolerate lower humidity, it's best to maintain moderate levels, especially for tropical varieties. Regularly check for signs of trouble, like leaf curling or browning tips, which may indicate the need for increased humidity. Group mature plants together, and consider using pebble trays or humidifiers during dry seasons.
Flowering and Fruiting Plants
Humidity needs: Flowering and fruiting plants often require higher humidity levels (50%-70%) to support the delicate process of blooming and fruit development.
Tips: Ensure that these plants receive enough humidity to prevent stress during the blooming phase. Misting, pebble trays, and strategically placing them in naturally humid areas like kitchens or bathrooms can encourage successful flowering.
By adjusting your humidity care based on the growth stage of your plants, you can foster a nurturing environment that will help them thrive at every phase of their development!
Troubleshooting humidity problems

When the humidity levels are too much or too low, plants can start to show a few signs of stress, like leaf curl or browning tips. Let's look at what these signs mean and what you can do to fix it.
Leaf curl
Symptoms: Leaves may curl inward or outward, kind of like a taco.
Causes: Leaf curl can be caused by low humidity, which can cause water stress in plants, or too much direct sunlight.
Solutions: Increase humidity by grouping plants together, using a pebble tray, or misting the leaves regularly. If light exposure is too intense, move the plant to a spot with indirect sunlight or provide some shade during the warmest hours of the day
Browning tips
Symptoms: The tips of the leaves turn brown and may feel dry and crispy.
Causes: Browning leaf tips are clear signs of low humidity levels or underwatering.
Solutions: Check the soil moisture; if it feels dry several inches down, it could be time for a drink. Water thoroughly and allow drainage. Increase humidity by placing a humidifier nearby, using a pebble tray, or misting the leaves to restore moisture.
Wilting leaves
Symptoms: Leaves appear droopy and lack firmness.
Causes: Wilting can be caused by both low humidity and overwatering, as plants may struggle to absorb moisture if humidity is too low.
Solutions: Check the soil moisture: if it's soggy, allow the plant to dry out before watering again. If the soil is dry, water a little more often and add humidity. If humidity is low, you can raise those levels with additional moisture sources, like misting or pebble trays.
Mold or mildew
Symptoms: White, fuzzy spots develop on soil, leaves, or the surface of the pots.
Causes: High humidity combined with poor air circulation can lead to mold or mildew growth.
Solutions: Ensure good air circulation by spacing out plants and not overcrowding them. Reduce humidity slightly by adjusting your watering routine or moving plants to a less humid area. Remove any mold or mildew with a damp cloth and treat the affected area with a diluted hydrogen peroxide solution to prevent further growth.
Yellowing leaves
Symptoms: Leaves turn yellow, especially older ones.
Causes: Yellowing can mean overwatering or nutrient deficiencies, but can also happen in low humidity conditions as plants struggle to maintain moisture.
Solutions: Check your watering habits. If the soil is constantly soggy, reduce watering and improve drainage. Consider increasing humidity as well, especially for tropical plants that thrive in moist environments.
Humidity for specific types of plants

Did you know that your plants have their very own preferences when it comes to humidity? Just like we love a cozy blanket on a chilly night, some plants thrive in high humidity.
