Succulents are easy to care for plants. They don’t need excessive watering, and they can offer an excellent appearance around the home compared to other plants. However, one thing that harms them is incorrect humidity, so to grow succulents in the right way, you need to ensure they have the right humidity level.
The amount of water vapor in the air and water vapor lead to a humid or not-so humid environment.
Because succulents are like cacti with thick leaves, you may think they like the same growing conditions. But, when growing succulents indoors, do they like high or low humidity?
In our guide, succulent growers can find out the answers. For example, why is humidity important for succulents, and what makes the ideal humid environment to grow healthy succulents that don’t foul fungal infections?
By the end, any succulent lover will see how easy it can be to help succulents deal with humidity and how much moisture they like in the air.
Do Succulents Like Dry or Humid?
And humidity doesn’t mix very well for too long. Succulents dislike humid conditions, but they can tolerate them for short periods. You will find the best humidity levels for succulents sit around 40% to 60%. If the humidity rises above these levels, succulent leaves and roots can face fungal problems.
What is Humidity?
The amount of water vapor in the air is referred to as humidity. It becomes humid when there is more water in the air—a hygrometer or an electronic sensor monitors relative humidity measures humidity. Relative Humidity (RH) can range from 0 to 100%.
Too many particles are present for sweat to evaporate when the relative humidity (RH) surpasses 40%.
This could cause an excessive quantity of heat and wetness, which could kill your succulents. This can be caused by rain, fog, or a plethora of plants and trees surrounding your succulents. (Learn How To Water Succulents Without Drainage)
When the relative humidity (RH) falls below 40%, there aren’t enough particles in the air to absorb any sweat. Because of the low humidity, your succulents will dry out and become brittle. This can be caused by an air conditioner, a stove or fire, or extreme cold.
Why is Humidity Important to Succulents?
Succulents are native to locations with little humidity; thus, they live in dry environments. These plants cannot survive high levels of wetness or excessive heat since the air and soil are dehydrated. Succulents need humidity because it helps them manage their water intake.
Without humidity, the air and soil are dehydrated, forcing the plant to collect moisture from its environment to thrive constantly. Because of this absorption, the plant’s leaves will droop as they strive to absorb more of the little waters available around them.
This might cause the succulents to droop or die on hot days.
Because it alters the water balance within each cell, a humid environment might cause your succulent outdoor garden to grow stressed out faster. Unfortunately, it also increases the likelihood of pests invading, such as mealybugs, snails, or slugs, and the intrusion of pests doesn’t do much to help your succulent.
Feeling for dryness in the soil or spotting mild wilting is the easiest way to see if your plant needs additional humidity. Should this happen, you’ll need to add more moisture levels in that region by occasionally spraying it.
Do Succulents Like To Be Misted?
Succulents that are fully developed dislike being misted. Because they are used to dry growing conditions, misting changes the humidity around the plant. This can also result in decay. Instead, you can take your propagation babes and delicately moisten their sensitive roots through misting.
Succulents That Like High Humidity
Succulents of various varieties thrive at slightly higher humidity levels. Here are a few examples of succulents that can live in dry and humid climates.
The Portulacara afra may grow in humid and dry conditions, requiring well-draining soil and plenty of indirect sunlight.
This succulent plant thrives if provided with these requirements, even if kept outside throughout the summer. When grown outdoors throughout the summer in temperate locations with high relative humidity, the Portulacara afra is one of the succulent kinds that like a humid climate.
Unlike other succulents, this one does not require its soil to be humid all year. Instead, it only requires enough moisture to prevent air bubbles from forming on the surface of the potting mix.
Ovata Crassula (Jade Plant)
The Jade Plant (Crassula ovata) is another name for Crassula ovata. It is one of the top succulent varieties that can grow with a higher-than-average moisture level for a succulent.
The succulent grows to around 12-inches with flat, oval-shaped grayish-green thick leaves and silver patterns. Crassula ovata does not grow in dry environments but thrive in high humidity.
You’ll need to keep your crassula ovata in a humid area with temperatures ranging between 60°F in the winter and 80°F in the summer for it to grow.
As the succulents grow, they need to be watered once or twice a week, depending on how much sunlight exposure they receive daily. The Jade plant prefers to be watered enough to keep the succulents soil moist but not soggy. (Learn How Long Do Succulents Last)
Sedum, often known as Stonecrop, is one of the popular succulents like humidity and comes in many strains.
Sedum is known as “impossible plants” because, with barely enough sunlight, the succulent’s humidity area can vary widely, as can the hot or cold temperatures (-40°F/-20°C).
It prefers humidity levels that range from 60% to 80% with good indoor air circulation, although they can survive at 30% to 50% humidity with little water as long as it gets lots of morning sun exposure daily.
Sedums should not sit in excess moisture, as they will decay. You will also need to improve indoor air circulation in the potting soil, as too much moisture collects around their roots. However, don’t let them dry, and keep moist soil or they will wilt and perish.
Sedums need watering every three days in humid conditions when growing succulents or your succulent plant leaves droop because of dehydration.
The succulent Kalanchoe blossfeldiana is native to South Africa and blooms orange flowers with green leaves.
The indoor succulents grow best in warm, humid temperatures of 50-60 degrees Fahrenheit during the day and 65-70 degrees Fahrenheit at night, so a well-lit window sill is ideal if it doesn’t get cold at night.
Because the Kalanchoe indoor plants are dormant during the winter, they will require less water to maintain their health until they blossom (November through March).
They need extra watering every few days in the summers when growing succulents, based on their size and how much sun they get outside.
To maintain a humid climate around your plant, you can water a little at night, so long as there isn’t any excess humidity that could lead to fungal disease.
When you ask, do succulents like humidity, the Aloe Vera plant comes to mind. From a young plant, the plant has long, pointed leaves with tiny spikes running the length of each leaf.
The succulent can grow to 30 feet and come in green, grey, and blue shades. Aloe plants are available in two sizes: full size and dwarf size. You can grow succulents outdoors or select the dwarf aloes to grow inside.
Do Succulents like Bathrooms?
Most succulents, mainly cacti, cannot thrive for long in a bathroom. This is because succulents prefer bright sunshine, dry environments, and low humidity.
Some succulents, like those above, prefer partial shade and moderate humidity and can thrive in a bathroom with some filtered, indirect light. A variety of factors determines the ideal humidity for succulents.
It’s essential to know how your plants grow and how much water they need before settling on a humidity level. For example, succulents do well in low humidity environments because their leaves hold more moisture than other plant species.
Because of poor drainage and excess standing water on top of most succulent species’ roots, too much moisture from high humidity causes root rot.
Excess water in the air or soil of humid climates may raise fungal disease during the summer months when the ambient heat in the dry air increases.
How to Measure Humidity Levels for Succulents?
A hygrometer is an ideal tool for measuring low or high humidity in succulents. The device can be used within your grow room and can be used quickly to take daily readings to see if you have high humidity.
High humidity refers to a level above 75% during the summer, which can cause too much moisture pooling on top of the roots, and since they can’t absorb moisture to this extent, they can rot and die.
Keeping Succulents Happy in Humid Conditions
If you have succulents in a humid area, here are a few things you can do to keep them healthy and happy:
Succulent roots do not tolerate standing water in a humid climate. Therefore, reduce humidity by providing better drainage.
When placing succulents on your windowsill, provide breathing room around them. They can get more air this way than if directed against the glass.
When watering succulents, soak the soil gently until thoroughly moistened, but avoid wetting the leaves as much as possible. Excessive humidity can cause fungus problems in these delicate plants, such as powdery mildew. (Learn How To Plant Succulents In Glass Containers)
Purchase a grow light. High humidity indoors often coincides with the cooler seasons. The sun is often scarcely visible. You can get around these problems by purchasing a grow lamp for your plants.
Are Humidifiers Good for Succulents?
If you have a large home with many succulents and air plants, a humidifier can help them thrive while saving you time.
The ability of a succulent to evaporate water is hampered by a combination of high humidity and insufficient air circulation. As a result, your succulent may rot if this happens for an extended period.
Plants have a hard time extracting nutrients from the soil during periods of excessive humidity. High humidity also encourages the growth of fungi, causing extra difficulties for you and your succulents.
In an ideal situation, your succulents should receive enough sunlight. Therefore, so many types thrive in the open air.
If you want to keep your succulents indoors, however, moving them from your home to your yard may appear to be a challenging undertaking. This is especially true for huge succulents.
Fortunately, you can do a few things to avoid these problems while also reducing the negative effects of high humidity in your house.
Don’t over-water plants.
One of the most important things to remember is that they dislike excessive wetness for succulents.
This is especially vital if you’re growing succulents inside and live somewhere with a lot of humidity.
It would help if you only water your succulents once a week during periods of excessive humidity. Then, if the soil is still wet, don’t water your plants again. This is the most crucial strategy for keeping your succulents healthy and preventing rotting.
Expert succulent gardeners frequently utilize lukewarm water to hydrate their plants during seasons of excessive humidity, especially during the winter. You can use this method in two different ways. First, it replicates the warm desert rain, and second, lukewarm water is absorbed more quickly.
It’s also a good idea to know when a specific succulent variety turns dormant. For example, succulents go dormant in the winter. On the other hand, some succulents go dormant in the summer.
Place succulents near windows
Succulents thrive in windows, which are ideal for a wide variety of plants.
When it’s humid outside, planting your plants near windows helps them get rid of extra moisture by increasing dry air and arid soil as they get more sunlight.
You should try to use pots with drainage holes if possible. For example, succulents should not be placed in glass bowls without drainage holes that allow excess moisture and more humidity to drain.
