How to increase humidity for indoor plants without a humidifier

You are a true gardener by heart and love your indoor plants, but do you know what your plants love? The humid temperature! Yes, you heard it right. In summer it may not be an issue as the room temperature is quite humid. But the problem arises in winters when you have all heated up rooms and humidity is quite low inside.

So in this article, I will cover how you can increase humidity for indoor plants without using a humidifier. Let’s begin.

First of all let’s see what is the optimal room temperature and humidity for Indoor plants.

The Optimal Humidity Level for Your House Plants

For these plants 50% humidity is not enough and some even go as high upto 80%, and it’s become really hard to maintain such humidity inside your room, especially in winters as air is cold and dry. Normally, the humidity in such times is around 20%, which isn’t enough. This is the reason indoor gardeners are always in need of ways to increase humidity in their homes.

Ways to Increasing Humidity of room for Indoor Plants

There are a lot of options to increase humidity, we will be focusing on major ones, which are scientifically proven to do so. Remember that we are increasing humidity because plants are more comfortable in high humid temperature as compared to low humidity.

Method 1 : Group your Plants

This is the most basic and most preferred method by everyone. It is a simple technique yet so efficient. If you ever visit a garden pack of plants, you will notice that there is quite high humidity in the air there. The reason behind this is the process called transpiration, in which plants lose water from their tiny pores, these pores are called stomata. The water released by these pores gets mixed up in the air and increases the humidity.

So when we group our plants together in the room, we are basically increasing the level of humidity in the air. This is the natural way to increase humidity.

But there is a drawback of this method too, sometimes it is the case that you don’t have many plants together. For eg: You have only a few plants in the kitchen or bedroom. So it becomes impractical sometimes.

 Method 2 : Putting HousePlants in the Bathroom

I know what you are thinking. Why would I put my plants in the bathroom? Now which place in your house is the most humid or which is wet almost all the time.

There is always something to dry there, like towels, sink etc thus humidity is quite high.

Of Course it is a bathroom. So in winters when you want to see your plants growing peacefully then it is a good idea to put these plants in your bathroom. 

Plants like Phalaenopsis Orchids, Bromeliads, Ferns and Peace Lilies etc require quite high humidity, so for such plants bathroom is the best place which can provide them with the adequate temperature.

Method 3 : Using the Pebble Tray

Another very simple yet amazing method to increase humidity for Indoor plants. For this method, you just require a tray that is quite deep and is large enough to hold two or more plant pots. We have said deep tray because it will ensure that the water doesn’t dry up quickly. Just put some pebbles into the tray and then fill it with water.

Now put your plant pots on the pebbles and make sure that it rests safely and doesn’t have a chance of falling. Also, make sure that pots don’t touch the water. Thus soil wouldn’t soak water and roots will become waterlogged. 

So slowly the water will evaporate and mix up with air thus increasing the humidity around the plants. And the best part is it wouldn’t increase humidity for the whole house.             

Yet there are disadvantages too with this method. As there will be long-standing water for a long enough time and thus resulting in the growth of fungal bacterias, mosquitos, etc. Which may compromise your plant’s health. So you will need to change water from time to time, to make sure that no such situation arises.

Method 4 : Misting your HousePlants

You can keep a spray bottle and spray water on leaves of your plants or even in the air near plants, thus it will result in an increase of humidity. After the leaves evaporate the water sprayed will basically result in humidity for a few hours.

Misting is a great way of increasing humidity but the only problem is that you will need to spray after every hour or so. Another issue is that keeping the plant moistened for long hours may result in fungal growth and in some cases it may even destroy the plant.

A solution to this is to try misting in the mornings, so your plants have a whole day for evaporation. Also, it may be impractical for several working people as they wouldn’t be around for misting from time to time throughout the whole day.

Method 5 : Using Two Pot Method

If you don’t have many plants and can’t group your plants to increase humidity, also you don’t wanna keep your plants in the bathroom, don’t worry we have another method for you which is especially for single houseplants. This method doesn’t even require you to relocate your plants.

The technique is quite simple, As the name suggests you will need two pots one with a quite bigger diameter then the other, now the pot with larger diameter is filled with sphagnum moss soaked in water. This technique is quite native actually but very efficient.

The wet moss will retain the water for a few days thus evaporation will take place slowly, resulting in high humid levels for a much longer time than any other method.

Remember to make a hole at the bottom of the larger pot so that water can drain slowly.


These are the top 5 methods to increase humidity for indoor plants without using a humidifier. You may choose whichever suits you the most. Happy Gardening. 🙂
