Are Mist Humidifiers Good for My Plants?

Humidifiers are devices used to increase the relative humidity in the air and help to conserve plant moisture, thus lowering the rate of evapotranspiration in plants. Mist humidifiers are in high demand during the winter. What is the primary purpose of having a mist humidifier? Well, primarily, humidifiers are designed for humans but not plants. This, however, doesn’t imply that their uses are limited to humans. Plants, just like humans, need certain levels of humidity depending on the environment and species to thrive. Mist humidifiers are not important but can be essential for some plants to grow and survive.

If you’re noticing your plants suffer, particularly in the wintertime, it may be due to a lack of enough humidity levels. Since many indoor plants are tropical varieties, they often appreciate a little extra moisture in the air. However, dry heat in homes doesn’t always provide for the best environment. 

If a plant is faced with dry heat and low humidity, then moisture will be wicked more easily from the plant’s leaves and you may notice leaf edges starting to turn crisp and brown. This means the plant will likely need more watering and a more humid environment. Here are some simple ways to increase humidity indoors, particularly in winter weather.


I would say this is the crudest way. You may need watering and humidifying the air at the same time. Watering enables the plant to intake water using the roots.


If there is enough humidity in the air the rate at which the plant loses water to the surrounding id low. This implies that the plant will remain healthy and protected from wilting and coloring due to a lack of enough water or humid air. Plants are also known to take in water through the pores on their leaves. This is only possible if the surrounding air is humid enough.

Why some plants need varying humidity levels.

Plants evolve to adapt to their native environments. If a certain plant is taken from its native or natural environment, customized humidity may be required to sustain it to a humidity level close to or similar to that in its natural environment. All plants vary from each other and thus will need different levels of humidity. For instance, most houseplants will need humidity levels of 40%-70% for orchids and 40%-50% for ferns

Warm versus cold mist humidifiers for plants

You may be wondering if it is good to use warm mist humidifiers for the sake of your plants. Whether you use a warm or cold mist humidifier it doesn’t matter. The dispersed mist by either warm or cold mist is barely noticeable when released in the air. Either type of mist humidifier will get the job done.

One potential benefit of cold mist humidifiers is that they use less energy compared to warm mist and can run for extended periods. This makes their overall maintenance cost a bit cheaper.

If you’ve ever walked into a botanical garden or been fortunate enough to travel to a tropical area, you’ve been blasted by warm, humid air. If you start having houseplants, I was shocked at how much humidity some of them needed to thrive.

Taking care of these plants may seem a simple task: you know just give them some humidity, right? Unfortunately, some areas have a lot of sun but low humidity levels. Also, you might find out that your plant species is the kind that does not need high humidity as well. This implies that you very much need customizable humidity levels.

Some people try humidity trays which are just trays half-filled with water and pebbles. You just place your plants on top of them and hoped for the best. It works-not the best way you would hope anyway. This method will most likely compel you to use humidifiers to solve the humidity problem. The problem is, most humidifiers are made for people, not plants. This means you have to dig deeper into the qualities of these appliances to figure out which is the best fit for your plants.

Advantages of having a mist humidifier for houseplants

1. By increasing the relative humidity, help reduce the rate of evapotranspiration in plants making them healthy.

2. Mist humidifiers help create an environment close to nature for which the plants have adapted. This makes prevents things like wilting in planting by customizing humidity levels to optimum.

3. Humidifiers prevent the plants from wilting which is caused by too much hot air by increasing the relative humidity in the air.


As pointed in the earlier sections of this article, plants just like humans need humidity to thrive well. Having a humidifier would do a great job of maintaining the required levels of humidity depending on the type of plant. If you have those tropical plants in your house or garden, then you need a humidifier to keep them healthy.
