Some indoor plants require higher humidity levels than what we often have in our houses. In fact, some people may even display health problems if they don’t obtain enough moisture in the air.
As worried houseplant owners, we frequently search for more obvious solutions (such watering or lighting) to address issues. When the problem could be resolved with a slight increase in humidity, we may instead overcompensate by giving our plant too little water or light.
Plants that need high humidity
High humidity is ideal for ferns, carnivorous plants, prayer plants, nerve plants, philodendrons, monsteras, orchids, fiddle leaf figs, anthuriums, and the majority of other tropical plants!
Symptoms of Low Humidity
Due to curling, the underside of this Calathea ornata leaf is visible and is a dark maroon color. The tip is dark as well. Both indicate low humidity.
Because some symptoms of low humidity can be confused with those of being underwater or having too much light, diagnosing it can be a bit challenging. The tips or margins of leaves are susceptible to drying out and turning brown. (Underwatering is typically observed more on the sides, whereas tips typically indicate concerns with humidity.) Flowers or leaves may wither and dry out. Some plants have leaves that curl downward or inward. A young leaf that unravels and seems deformed may have grown when the humidity was too low.
Symptoms of too High Humidity
Some plants, such as the majority of cacti and succulents, favor dry environments. For too long, extremely humid conditions can cause fungus problems, which can cause the plants to lose leaves or branches and eventually perish. Overwatering could potentially cause similar symptoms.
Seasonal Differences
During the warmer months, a typical residence has a relative humidity of between 40 and 60 percent. While many houseplants are OK with this, some might require some additional care in order to thrive.
The relative humidity of a typical home drops to between 10% and 40% in the winter, especially when the central heating is on. This will be difficult for many plants, so you might need to take some action to raise it. Of course, most succulents and cacti won’t experience any problems!
Humidity and Air Circulation
If you want to increase humidity using any of the following methods, please also provide adequate air movement. A combination of high humidity and poor circulation might lead to fungal problems.
How to increase humidity?
Placement of plants in an area of your home that is naturally more humid is one of the simplest ways to boost humidity. Examples are the restroom or the area around the kitchen sink.
Grouping Plants
You might also consider putting your plants that benefit from dampness together. Plants enhance the humidity in their immediate environment by transpiring. They form little micro-climates with enhanced humidity when they are gathered together.
Humidity trays
You may easily raise the relative humidity directly around a plant by placing pebble trays with water in them underneath your plants. Make sure the stones are keeping the pot’s bottom above the water if you don’t want the substrate to become overly soaked (potting media.)
Humidifier
If you want more control over your humidity levels, buying a humidifier can be the best option. Many allow you to choose a desired level of humidity, and they will adjust their moisture production to meet that target.
Fountains and Aquariums
Other alternatives include an open-air aquarium or a bubbling, moving fountain like the one shown at the top of this piece. Aqua-scaping ideas can also be found in aquariums. (As an added plus, aquarium water makes excellent, gentle plant fertilizer.)
Terrariums and Cloches
Making a humid environment inside a transparent enclosure or dome is a fun technique to raise humidity. Any glass or plastic container can be used for this. Remember to sometimes open your vessel if it is primarily closed to ensure that your plants receive enough air circulation.
What About Misting?
Misting is frequently recommended as a means to boost humidity, however it has a minimal overall impact and only temporarily raises humidity. Plants will absorb water drops that fall on their leaves, but misting can also cause water to remain on leaves for an excessive amount of time, which may result in fungus problems (especially in cooler temperatures.)
Which houseplants are capable of absorbing humidity?
An excessive amount of humidity in your home leads to wetness, mustiness, and winter mildew. The problem also exists in hot, humid climates. Plants are a lovely, more natural way to reduce some of the damp air and humid environment. Dehumidifiers and other methods can have an impact.
Humidity-absorbing indoor plants provide a dual role by absorbing moisture from the air and releasing it outdoors.
Which plants are hygrophilic?
- Fern. According to Mast, several ferns, like the Kimberly queen fern, bird’s nest fern, and blue star fern, thrive in additional wetness and flourish nicely in a bathroom habitat.
- Gardenia.
- Viper plant
- Venomous plant.
- lounge palm
- Plant a prayer.
- Nerve tissue.
- Monstera.
Which plants do humidifier trays favor?
Homemade pebble trays are surprisingly simple to make. How can you tell if your plants need more ambient moisture before learning how to construct a pebble tray? A lack of humidity can result in browning leaf tips and edges, curled or wilted foliage, and malformed or damaged new growth.
Typically, tropical areas are home to plants that enjoy additional humidity. We particularly appreciate ferns, Begonias, and prayer plants (such as Maranta, Calathea, and Ctenanthe) as plants that thrive in high humidity.
- Locate a shallow tray or dish that can store water and is the right size for the plant or plants that require more watering.
- Put beautiful rocks or stones in the tray.
- Make sure to add water until the tops of the stones just barely protrude above the water’s surface. In this manner, the roots of your plant won’t be submerged in water when you set it on top.
- I’m done now! Regularly check in to refill the tray as necessary. This may occur quite frequently during heat waves and in dry places with air conditioning
Use of a humidifier or mister is another simple method to increase humidity in a space. Get a larger humidifier for large rooms and a smaller humidifier for small areas so that the humidifier is the right size for the space. Large water droplets shouldn’t ever remain on your delicate leaves for an extended period of time, hence misters should have a fine spray. The next time you take a shower, you might even think about bringing your plants along for a field trip to your bathroom so they can enjoy the steam!
In order to stop your friends’ tips from browning, just add some beautiful stones to a small bowl of water and let science take care of the rest.
Are houseplants tolerant of high humidity?
Since many of our indoor plants are native to humid jungle conditions, maintaining air moisture is essential to maintaining lush, healthy plants. In particular, during the winter when fireplaces and heaters dry up the air, the optimal humidity for houseplants is 40–60% higher than the humidity levels present in our houses. It’s critical to raise the humidity for your plants in the winter to give them the best possible living conditions.
There are a number of ways to keep your plants (and yourself!) healthy and happy during the dry winter months, in addition to watering them frequently.
Do spider plants make the air more humid?
According to 2015 research, spider plants are among the best plants you can buy for boosting indoor humidity.
NASA also concurs. It conducted a study in the 1980s and discovered that indoor air pollutants including carbon monoxide and formaldehyde can be eliminated by spider plants.
Their stems lengthen. The plant will cascade best in a hanging container.
Try to maintain spider plants next to a window that receives lots of natural light because they thrive in bright, indirect sunshine. Try to maintain a wet but not saturated soil.
What about spider plants and humidity?
For plants to be healthy, the right temperature and humidity must be provided. Here are some details on the optimum surroundings for your plants.
Ideal Temperature
The ideal range for spider plants is 65° to 85°F. However, they can withstand brief exposure to temperatures outside of this range.
A thermometer is the most accurate tool for measuring the temperature indoors. As temperatures might differ from room to room in a house, check the temperature where your spider plant is located.
Along with maintaining the appropriate temperature, you want to stay away from both hot and cold drafts. As a result, you should keep your spider plant away from an outside door, a window with weak insulation, a fireplace, and a heating vent.
Finally, avoid sudden temperature changes. Although these plants can withstand little temperature fluctuations, large ones can stress them. As a result, avoid transferring your plant abruptly from a cold environment to a warm one. Instead, give your plant time to adjust.
Ideal Humidity
In terms of humidity, spider plants like a range of 40 to 80 percent for optimum growth. Your plants will be able to generate lots of strong new growth as a result.
Having said that, spider plants can thrive in environments with lower humidity levels of less than 40%. They won’t flourish as much as they would with higher humidity, though.
An instrument called a hygrometer is the most effective tool for measuring humidity. This will give you an accurate reading of the humidity.
However, the time of year and the feel can also help you determine the humidity. During the warmer months, the humidity in your home will often be higher than 40%. If you reside in a cold climate, though, indoor humidity frequently decreases throughout the winter.
The air is probably too dry for your spider plant if it feels dry to the touch and you have nosebleeds. Consider taking steps to increase the humidity in your home to keep your plant happy.
Using a humidifier is a choice. This will assist in maintaining a constant humidity level. Other methods include putting a tray with water and pebbles underneath the pot of your plant.
Picking a Location for Your Spider Plant
As previously said, keep your spider plant away from drafts that are both hot and cold. Once you’ve located a spot with the right temperature and humidity, you should consider a few other elements.
Does humidity favor succulents?
An average residence has a humidity level of 30 percent or less. The majority of plants, including succulents and cacti, enjoy humidity levels of 40% or greater. The majority of tropical plants need at least 60% humidity. In our experience, a humidity level of at least 50% is ideal for both people and plants in a house.
Your plants will probably let you know if they need more or less humidity, so you don’t need to measure it precisely (hint: keep reading to the next sections). However, there are several affordable, trustworthy hygrometers accessible online if you are worried about getting the humidity precisely right. This is the one we employ.
House plants typically require less warm air and more wet air than you may imagine. Usually, leaves that are papery or thin, like those of a fern or air plant, require more humidity than leaves that are robust, like those of a fiddle-leaf fig. If you wish to cultivate plants other than succulents and cacti in your house, we advise using one of the following strategies to raise the humidity there. This will ensure that your plants are healthy and happy.
Does pothos enjoy moisture?
accept low and medium light. In brighter light, the variegation will be more noticeable. Direct sunshine will not be good for your Pothos because it will scorch the foliage.
In the saucer, they gathered. Watch out for yellow leaves; they are a sign of excess moisture.
Although it will flourish in a more humid setting, such a bathroom or kitchen, this plant will survive in low-humidity areas. Brown leaf tips could be a sign of very dry air.
Use a general-purpose indoor plant fertilizer to feed your plants once a month or every other month in the spring and summer. Make sure the soil is moist before adding any fertilizer, regardless of form.
Both people and pets are slightly poisonous from pothos. Ingestion frequently results in tongue and stomach discomfort, as well as potential vomiting.
As they appear, remove any stems or leaves that are infected, damaged, discolored, or dead. In order to prevent ripping or bruising of the stems, use clean, sharp scissors. Just above a leaf node, trim stems; new growth will sprout from this cut.
Does snake plant enjoy moisture?
The ideal humidity range for your snake plant is between 30 to 50%, which is what most homes typically have as their usual humidity level. This indicates that the Snake Plant frequently favors our environment. Find out how to dehumidify your area here if you need to.
How to Tell If A Snake Plant Needs More Humidity?
Your Snake Plant will effectively start battling for additional moisture if there isn’t enough humidity for it. Plants will display thirst-related symptoms if there is insufficient moisture. The most typical indications that your plant needs additional humidity are listed below:
- The edges of leaves turn dark.
- Plants droop and wilt.
- Yellowing of the leaves
- The leaves become touchably crisp.
Are humidity trays effective?
No and yes. For indoor plants, pebble trays can only go so far in raising the humidity level. Since your plant’s pot is on top of the tray, the water from the tray should evaporate upward, providing your plants with additional hydration.
Due to the fact that your plant is not resting in a water puddle, this strategy prevents root rot. Instead, it is perched a little higher than your pebble tray. The humidity level can always be checked using a hygrometer to see if the pebble tray is effective.
A humidity tray won’t normally help your houseplants much if your home is frequently drier than average. It would hardly provide the air with enough moisture to make your plants happy, much less your tropical plants, which need a medium to high level of humidity.
Personally, I prefer to use these trays primarily as decoration. Pebbles really make potted plants look so much more elegant. When you need a little more humidity but not enough to purchase a humidifier, pebble trays perform much better.
Your tropical plants will benefit from making a tray once the temperature begins to drop. The humidity levels will alter little, but if the weather continues to become colder, buying a humidifier might be a smart move (this one does an incredible job).
