Do Succulents Like Humidity?

Succulents are low-maintenance plants. However, you still need to make sure that factors like temperature, sun exposure, and humidity suit their requirements to grow into happy and healthy plants.

That said, do succulents like humidity?

Well, the quick answer is yes. Succulents like humidity as long as its level is 40 to 50%. Very high humidity can be hazardous for your plant as it can lead to wilting, while low humidity can cause complete dryness.

What Happens to Succulents in High Humidity?

Succulents can’t tolerate high humidity because it keeps them from conducting the transpiration process. It’s an essential step for them to draw nutrients from the soil.

The same concept applies to succulents. They become overwatered whenever they get exposed to high humidity for an extended period. Excess moisture will put them at risk for various problems since they already store water in their leaves.

So, the following are the issues that your succulent might experience if it gets exposed to high humidity:

1.   Root Rot

If your succulent pot doesn’t have enough drainage holes and the room has high humidity, the plant can develop root rot.

The excess moisture turns the roots into a breeding ground for pathogens that can attack your plant from the ground up. Some symptoms of this issue include the wilting of leaves, stunted plant growth, and root lesions.

Sadly, fixing this problem depends on how early you notice the issue.

However, some solutions include trimming the roots and letting the whole plant dry out. If the leaves become infected, you have to salvage the uninfected part by propagating it.

2.   Gray Mold

An abundance of moisture in the air also puts your succulent at risk for gray mold.

Botrytis cinerea thrives in high humidity and prolonged moisture. This necrotrophic fungus is one of the most destructive among horticultural props because it quickly spreads from one plant to another.

If your succulent gets in contact with a spore, it’ll instantly infect the whole plant. The leaves will become soft, and they’ll get a coating of gray fungus.

Leaving it untreated can lead to the death of the affected areas.

You can use dishwashing soap as a homemade fungicide to treat your plant. Ensure it doesn’t contain bleach, as it’s harmful to your succulent. If the infection is severe, you have no choice but to cut the affected areas.

3.   Leaf Spots

Out of all the issues that your succulent might face when exposed to high humidity, leaf spots are the least harmful. It’s because they don’t kill your plant completely.

Additionally, they take at least 12 to 24 hours before the infection starts.

However, leaf spots can weaken the leaves and stunt the growth of the succulent. Furthermore, not treating the fungus right away will cause it to start spreading.

The color of the leaf spots may vary, but common colors are yellow, tan, black, and brown.

You can use a fungicide if your succulent gets infected with leaf spots. A good alternative would be creating a mild solution by adding half a teaspoon of baking soda to a gallon of water.

Tips on How to Reduce Humidity for Your Succulents

It’s pretty challenging as a plant owner to control your home’s humidity, but it’s a must because your plants’ life is on the line.

That said, here are some tips on how you can reduce your home’s humidity:

1.   Use Your Air Conditioner

Air conditioning

If you’re keeping your plants in an enclosed room, you should turn on your air conditioner. It’s because the said appliance introduces cool air to the confined space.

As a result, it’ll balance out the warm, humid air.

2.   Get a Dehumidifier

Dehumidifiers are an excellent way to keep the humidity in your house balanced.

Unlike air conditioners, these devices don’t alter the room’s temperature. Moreover, dehumidifiers can prevent the production of mold.

3.   Move Your Succulents to a Less Humid Location

Because of transpiration, keeping all your plants together in an enclosed room is a no-no. When succulents release excess water in their bodies, it evaporates into the air and turns into moisture.

Again, too much moisture in the air will result in higher humidity.

So, transferring your succulents to a place with fantastic ventilation is ideal. It can be in a room with a window or any open area.

What Happens to Succulents in Low Humidity?

Succulents can survive without water because their roots can search for water in dry soil. Additionally, their fleshy leaves store water, all thanks to the waxy layer covering them.

Despite their ability to live in a dry area, they still need the right humidity level. Whenever the moisture in the air is too low, they speed up the transpiration process, which means that they lose more water.

The following are the risks that your succulent might experience in an area with a low humidity level:

1.   Stunted Growth

Succulents lose water in their bodies at a quick rate if they stay in a dry environment.

Water is essential for plants because they use it for photosynthesis, a process they perform to create their own food. If they don’t have any source of liquid, then they won’t be able to get the appropriate amount of nutrients they need to grow properly.

If your succulent is growing at a slow pace, then it might be because of low humidity.

2.   Dryness

Of course, if your succulent constantly transpires just to get the right amount of moisture and water it needs, it’ll exhaust all the fluids in its body.

As a result, your plant will completely dry out. Its leaves will start to wrinkle and will turn brown.

Luckily, you can fix this by soaking the pot in a larger container with water to moisten the soil.

Tips on How to Increase Humidity for Your Succulents

If you want to increase the humidity in your house, you should keep these tips in mind:

1.   Mist Your Succulents Regularly

Misting your plants is the easiest way to increase the humidity around them. However, it’s only a band-aid solution, as the water will slowly evaporate after a few hours.

It only provides a gradual increase in humidity because once the mist has evaporated, the atmosphere won’t retain any moisture.

So, this method is ideal only if you want to ensure that your succulents have enough moisture, especially on hot days. Make sure that you don’t spray too much water on the foliage, for it increases the risk of mold and fungi.

2.   Use a Humidifier

In case your home’s humidity level is constantly dropping, you should invest in a good humidifier. This device releases water vapor into the air, resulting in an increased moisture level.

Just place it where you keep your plants, and you’re good to go!

The great thing is that there are humidifiers that allow you to set a particular humidity level, while some will enable you to set a time when the device will operate.

You won’t have to exert any effort by constantly measuring the moisture levels in your room because the device will do it for you.

3.   Place Your Succulents in Your Bathroom

Your bathroom has the highest humidity levels in your house. Whenever you take a hot bath, moisture drifts into the air.

Eventually, the moisture will accumulate in the room, which increases overall humidity.

With that said, it’s ideal to transfer your succulents to your bathroom so that they can absorb all the moisture present in the air.


Now, do succulents like humidity?

Yes. Your plant will thrive if you maintain the right moisture levels in your house.

Keep in mind that aside from watering them regularly, moisture plays a significant role in the growth of your succulents.
