Why I Needed A Humidifier for My Houseplants

I live in Milwaukee, Wisconsin, and it’s no joke that our winters are cold AF and therefore, the air in our home is dry AF! I was having a difficult time keeping the humidity high in my house during the winter months when we are blasting the heat 24-7, and my houseplants were starting to suffer and die because of the low humidity levels.

I decided to buy a humidifier to help increase the humidity levels in my home without spending too much money. I did my research and purchased a humidifier on Amazon and it has made a big difference in the health of my plants!

How to Tell if Your Plants Need More Humidity

If you’re unsure whether or not your plants need extra humidity, there are a few signs to look for.

  1. If the leaves of your plant start turning brown around the edges and curling up at all times during their growth cycle, this could be due to too little moisture in the air surrounding them. Humidity levels should range between 50-60% for most houseplants.
  2. Humidity levels can also be affected by your environment, such as the temperature inside or near their location and if there’s any air conditioning running nearby which might dry out plants more quickly than usual during hot weather months when they need extra moisture even though they’re growing well otherwise. Humidifiers can help counteract the dry air and ensure your plants are getting the humidity they need to stay healthy.
  3. Another way to tell if your plant needs more humidity is by checking the soil. If the top layer of soil feels dry to the touch, it’s a good indication that your plant isn’t receiving enough moisture from the environment. In this case, you may need to increase the humidity levels in your home with a humidifier.

Humidifier Size Matters

Adding moisture is beneficial but can be harmful if it’s too much or not the right type for your plants. Humidifiers come in different sizes and styles so be sure to research what will work best for you.

When it comes to picking the right humidifier, size matters! You’ll want to choose a model that can cover the area where your plants are located. If you have a large collection of plants, you may need a humidifier with a larger water tank to provide adequate coverage.

Different Types of Humidifiers

Humidifiers also come in different types, so it’s important to choose one suited for your needs.

Cool Mist or Vapor

If you’re looking for a model that will help your plants grow lush and healthy, you’ll want to look for a humidifier with an output of mist or water vapor. Humidifiers that emit a fine mist are ideal for increasing the humidity levels in your home and helping your plants thrive with high humidity.

Ultrasonic Technology Humidifiers

 Ultrasonic humidifiers are a quieter option and work by emitting a fine mist into the air. This type of humidifier is ideal if you’re looking for one that won’t disturb your sleep or daily routine while providing adequate moisture.

Steam or Warm Mist Humidifiers

Warm mist humidifiers emit gentle, warm steam to help soothe colds, cases of flu, and other respiratory issues. If you’re looking for a humidifier to help with your plant’s health and also want one that can provide relief from respiratory problems, a warm mist humidifier is an ideal option.

Steam humidifiers work by adding moisture into the air, which can be beneficial if you suffer from dry skin or sinus congestion. Humidifiers that emit steam are also great for relieving symptoms of colds and flu because the warm mist helps loosen mucus in your nose and throat.

Evaporative Humidifier

An evaporative humidifier is a device that increases the humidity, or moisture, of the air. It does this by evaporating water into the air. The water that is used in an evaporative humidifier can come from a variety of sources, including tap water, distilled water, or even rainwater. Evaporative humidifiers are often used to help alleviate dry skin, nasal congestion, and static electricity.

In addition, they can also help to prevent furniture and wood floors from drying out and cracking. There are several different types of evaporative humidifiers on the market, so it is important to choose one best suited for your needs. Some factors to consider include the size of the unit, the type of filter, and the capacity.

Now that you know some of the different types of humidifiers available, let’s discuss how to pick the best plant humidifier right one for your needs!

FAQS for Houseplant Humidifiers

1. Is too much humidity harmful to plants?

Yes, too much humidity can cause a plant to rot. It would be best to regulate the amount it gets each day.

2. How else can I raise the humidity level in my home for my plants?

The easiest way is to use a humidifier and spray the plant with a fine water mist.

3. How long and when do I run a humidifier for my houseplants?

I recommend running humidifiers for at least three hours from mid-morning until midday every two days.

4. What is the difference between a warm and cool mist humidifier?

A warm mist humidifier boils water and emits hot steam. A cool-mist humidifier does not heat the water but uses evaporation to produce moisture.

5. Do houseplants like warm or cool humidifiers?

When it comes to the humidity your plants prefer, mist temperature isn’t as important as you think. Warm mist tends to be cleaner because it’s generated by evaporation. Still, the cold-mist is a little more cost-effective to develop because cool-mist humidifiers require less energy to run.

6. How close should a humidifier be to a plant?

Ideally, the humidifier should be placed within a foot of the plant. If that’s not possible, try to direct the mist toward the leaves.

Humidifiers can be an excellent way to raise humidity levels for your plants and keep them healthy and thriving.

7. Is a cool mist or warm mist humidifier better for plants?

When it comes to plants, the debate over cool-mist versus warm-mist humidifiers has been raging for years. Both types of humidifiers have their pros and cons, and ultimately the best choice for your plants will depend on a variety of factors.

For example, tropical plants tend to do better with warm mist humidifiers, while ferns prefer cool mist humidifiers. In general, plants that require high humidity levels will benefit from a cool mist humidifier, while plants that prefer lower humidity levels will do better with a warm mist humidifier.

Ultimately, the best way to determine which type of humidifier is best for your plants is to experiment and see what works best for them.

8. How long do you run a humidifier for plants?

You should use a humidifier until the humidity hits about 60%, which can take 3 to 7 hours to achieve during the morning to mid-day. Running it too late into the afternoon risks leaving too much moisture in the air overnight when the plant doesn’t absorb it as much, which increases the risk of mold or fungus.


Humidifiers are an excellent way to increase and maintain the humidity in your home. Not only do they help your plants thrive, but they can also provide relief from dry skin and sinuses. So, if you’re looking for a little extra help taking care of your plants or want to make sure you’re staying healthy this winter, consider investing in a humidifier.
