How to Increase Humidity for Houseplants?

Some plants grow in the tropical region while growing outside, and the environment of the forest or jungle environment provides them the perfect humidity to grow and be fresh. But when you want them to grow inside your house, you have to be very careful about the temperature and humidity.

Step 1 – Try To Mist Your Plants

How to Increase Humidity for Houseplants - step one - Try To Mist Your Plants

You want to know “how to increase humidity for houseplants?” this is the first step you can take to increase the humidity.

Misting your plants may be the quick and easiest way to increase humidity for houseplants. Try to spread water on your houseplant the way you drink water daily. Do not pour water directly on the plants. Use a sprayer that will evenly distribute the spreading water on the leaves of plants, or you can use your hands as well.

This will prevent the plants from drying out and being brittle. Try to mist the plants thrice a day according to the weather outside. If it’s Winter, do it regularly because the air remains cold and has less humidity, and if it’s a rainy day, do occasionally. Mist your plants once or twice when it’s summer.

Misting in the morning is the best. If you spray water on your houseplants early in the morning, the excess water gets enough time to evaporate by sunlight. It will also prevent your plants from fungal or bacterial growth.

If you have any plant with hairy leaves, do not mist too much because the hairy leaves accumulate the water in one place and may cause fungal production or other problems.

Do not water them more often as too much water can cause diseases to your plants.

Try to spray water in a place away from wooden furniture in your house. Water can damage or cause discoloration. Better if you water them in the bathroom or sink.

Step 2 – Decorate Your Plants Group Wise

As you asked, “how to increase humidity for houseplants?” we are providing steps and ideas to help you. But this one is not enough efficient to increase the humidity for houseplants. 

Have you ever feel the humidity while walking through a forest?

It is because in a forest all the plants are located near one another. If many plants grow closely in one place, the air is released from the plants by transpiration and humid the atmosphere.

Similarly, if you keep your plants together in a place, it will naturally increase the humidity of that area by transpiration. It is the natural way to increase humidity in the air for houseplants.

But some drawbacks are there in this way. Not everyone wants to put all of their plants in one place but spread at every corner of the house. For them, this trick will not work.

Step 3 – Use a Humidifier In Your Home

You wanted to know “how to increase humidity for houseplants?” Right? This is the best way to do it.

If you don’t want any hassle for keeping your houseplants humid but want them to grow well and fresh, you have no other option but to bring a humidifier for your home!

A humidifier will refresh your home, your houseplants, and you too.

Many people might concern that their home will get so humid that microbial growth or damage to furniture can be occurred by using a humidifier.  This situation has a solution as well. If you keep your humidifier in an upper place where the humidity can be adequately spread, you can overcome microbial growth or any damage. Do not put a humidifier directly on the floor.

In Summer, a humidifier is not necessary for your plants. It can cause increased humidity above the normal range within your house, which can cause various problems for your health and your plants too!

You can use a humidifier, especially in Winter, when you need increased humidity for you and your plants.

Step 4 – Use Terrariums or Pebble Trays

You often get the advice to use a pebble tray to increase humidity for houseplants. Have you ever think how this is going to be worked?

A pebble tray is when you add pebbles over a tray and add water to it until they cover the pebbles. Then you put the pot of your plant over it so that the pebbles prevent the plant’s root from constantly being close to the water beneath it.

It is thought that the water evaporates from the pebble tray will increase the humidity of the air, which will benefit the plants.

The water that evaporates will spread throughout the whole room or the house by diffusion and hardly increase 2-3% of the overall humidity. This is not just going to be worked for your plants. That’s why the pebble tray does not work correctly.

Now, set up a terrarium by putting some stones or rocks in an aquarium and putting the plants inside it. You will be able to increase the humidity up to 100% without precipitating any water. Because plants naturally exhale CO2 by transpiration, which increases the humidity.

Cover fully if you want to get a 100% humidity environment but be careful about the growth of microorganisms like fungus. A long time of humidity can cause damages to your plants. Cover it partially or sometimes uncover it for one or two hours to control the moisture.

Step 5 – Place Your Houseplants In The Most Humid Area

When someone asks you, “What is the most humid place inside your home?” What will be your answer? Probably, the bathroom and the kitchen?

Yes, the kitchen and the bathroom are the most naturally humid area of our house. So, if we worry about how to increase humidity in the air for houseplants,  we can easily put them in these areas.


A bathroom with a nice window can be a better place to keep houseplants, which increases the freshness of your bathroom and helps the plants by increasing humidity. Whenever you take e hot shower, the moisture automatically increases, and you don’t have to do any extra stuff to improve it.

Similarly, the kitchen is also a humid place while cooking something. The vapor produces while making food increases the moisture content for that area. Putting some green in your kitchen is not a bad idea, though!

But this way is not always going to be worked because you will only get humidity while using it. The bathroom is only humid while taking a shower and the kitchen while cooking. Even modern kitchens and bathrooms have the facility to pull out the extra humidity from inside.

Step 6 – You Can Simply Give Bath to Your Plants

This method will give you less work than the other methods. You can use two pots; one is a little bit bigger than the other one. The larger one will be the outer, and the smaller one will be the inner pot.

Keep the smaller pot, which will be the pot with plants. Inside the bigger one, in the space between these two pots, put some moss with water to retain the moisture for a long time and evaporate slowly.

What is Relative Humidity?

When people talk about humidity, they are actually mean humidity, which is related to the temperature. Humidity is closely related to temperature. But how?

Do you know what saturation is?

Saturation is the state when something stays at its highest capacity. For example, the air is 100% saturated with water, which means air cannot absorb more water because it is in its highest degree to uptake more water.

Now, warm air has better saturation skills than cold air. Warm air can uptake more water from the environment and serve more humid air than cold air does.

Even when air humidity will be same, water absorption into the air will vary with the different temperatures. For example, air with 50% moisture and 90F temperature will absorb more water than air with 50% moisture and 70F temperature.

That is why you should be careful while increasing your houseplants’ humidity and maintaining the temperature correctly.

How Does The Humidity of Our Household Increase?

Houseplants need around 40-60% of the relative humidity to grow properly. Below or above this range may cause severe problems for houseplants for growing.

If the air gets too dry, the leaves will not get enough water and fall out of the plants. Often the leaves change their color, and so the edges.

Sometimes they turn brown and also pests, insects start to destroy them. Plants also need water for their nutrition which comes from the humidity of the atmosphere.
