8 Ways To Increase Humidity For Houseplants That Work

Plants growing indoors need warmth and humidity to thrive well. Learn how to increase humidity for houseplants in this article.

Plants growing indoors need warmth and humidity to thrive. Foliage is turning yellow, looking dead, drying and falling are one of the signs that houseplants need more humidity. Those of us who live a cool climate face this a lot. Although, there are some solutions you can opt for, shown in this list.

1. Misting

Humidity is nothing but water vapor present in the air for a long time. Misting has a somewhat similar effect but for a very short duration. The particles are not as tiny as water vapor in the air, so they settle down quickly.
Misting the houseplants is a temporary way to increase the humidity around them. Moreover, it’s not as effective as other solutions listed below.
For this, fill water in a spray bottle and mist the plants. It is an inexpensive and effortless solution to try.


  • Plants with fuzzy leaves should not be misted.
  • Ugly streaks will appear on the walls if someone smokes in the house. So get rid of this unhealthy habit.
  • Some houseplants tend to attach themselves to walls for growth if they are placed nearby the walls while misting, displace.
  • Mist the plants in the morning so that they’ll have the chance to dry out before the cool evening.

2. Pebble Trays

As it might be clear from the name pebble trays are nothing but trays filled with pebbles and water. The pebbles should form a thick one or two inches layer. Now, place the houseplant on this tray.


  • You’ll only be able to do so if the width of the tray is more than that of the pot.
  • The tray should not be made of terracotta or any porous material and promotes leakage of water.
  • Also, the bottom of the pot shouldn’t sit directly in the water as it can cause root rot.

3. Glass or Bowl

It is an effective way to maintain moisture for small houseplants. Note that the depth of the bowl or glass should be more than the height of the plant. You must have seen plants grown in glass globes and thought it was for aesthetic reasons. Well, apart from aesthetic reasons it is also to create a contained environment to increase humidity.


  • We suggest you choose transparent clear glass for planting as you’ll be able to judge whether the soil is dry or moist just by looking at it.

4. Terrarium

It works the similar way, the concept mentioned above, but on the broader scale. Plant’s leaves cause evapotranspiration, which raises the humidity levels in a contained environment. Terrariums are closed or semi-open glass structures, you can also use aquariums as terrariums. Place the pots in the aquarium or plant the houseplants directly in the aquarium. It’s up to you!

If not in the terrarium, you can also group your plants together in the room to increase the humidity level. Plants growing closely create a humid microclimate, so it’s a clever idea to group them together.


  • Air plants and succulents are not a good option to grow in a closed terrarium as they constant air circulation, plant them in an open terrarium.

5. Humidifier

This device is used to raise the humidity levels in the room or a building. A point-of-use humidifier can sufficiently increase the humidity for houseplants. However, humidifiers are expensive as compare to other methods listed in this article. Still, they’re the most guaranteed way to increase humidity.


  • Mold, salt, and fungus can build up because of the high humidity in humidifiers. Hence, it is crucial that you clean the humidifier once or twice a month.
  • Soak the parts of a humidifier in a solution of water and vinegar for cleaning the parts of the humidifier.
  • If you observe molds and fungus on the foliage of your houseplants, clean the foliage gently with a moist cloth.

6. Pot in a Pot

Select a one or two sizes bigger pot than the pot of the houseplant. Fill the pot with water and place the houseplant in this larger pot. Keep in mind that the larger pot should be waterproof to prevent leakage. You can also place sphagnum moss in the gap. As the water evaporates or the sphagnum moss dries out, thus humidity level rises.


  • This method will be most successful for plants that love moisture and humidity and if you’re growing them in a dry and warm climate.

7. Best Location

A great way to ensure that plants receive proper humidity is by placing them in a suitable location. Place the houseplant at a place where the moisture content remains high. Windows in the bathroom or nearby the kitchen sink are perfect spots for houseplants. The evaporated water from your steamy showers, cooking, and other things keep the humidity loving plants healthy and growing.


  • Ensure adequate light for your houseplants when you place them in these spots.

8. Steam from Warm Water

Place any heatproof utensil filled with water nearby them. The heat produced by them will cause evaporation and ultimately increase in humidity due to the steam in the air.


  • Avoid touching the utensil with bare hands when you refill as it might be too hot for touch.
