Ever wondered why your plants are suffering, especially in the wintertime? It is due to the lack of humidity, and that’s where humidifying plants becomes a necessity. 

Before you brought those plants to your home, they most likely spent weeks or months in a warm, humid greenhouse.

Many indoor plants are tropical varieties, so they need a little extra humidity, which your home might not have. Compared to a greenhouse, most homes are quite dry, especially in the wintertime, and don’t have a humidifier for plants.

How to Humidify Plants: Increasing Humidity for Houseplants (DIY)

If a plant is faced with low humidity and dry heat, you may notice its leaf edges starting to change color and turn crisp. Lack of moisture also encourages infestations of red spider mite, which will feed on the plant’s sap and make the plant weaker.

Mind you, the humidity in your home can also be too high. If the moisture in your home is too high, your plants won’t grow well.

If you are unsure about if the humidity in your home is low or high, check out for these signs in plants:

If the humidity is too low, you might see these signs:

  • Flowers start to dry up
  • Tips of leaves turn yellow or brown and very brittle
  • Leaves don’t grow properly, will look stunted, and will crumble when touched.

If the humidity is too high, you might see these signs:

  • Black spots may appear on plants
  • Leaves and stems of the plant become slightly yellowed and soft, leading to rotting
  • Fuzzy white and grey mold forming on the leaves, stems, and flowers.

I suggest you get a hygrometer or moisture meter to help you figure out the humidity level in your house and moisture on the soil.

How to Increase Humidity for Plants Indoor

1. Buy a humidifier

Buy a humidifier

If you want to increase humidity, the most guaranteed way to do so is to buy a humidifier. Humidifiers are easy to use, and they don’t need a lot of upkeep if you choose the right one.

However, before buying a humidifier, there are some things you should consider:

  • Light and noise: If the humidifier is in areas like your living room or bedroom, you want to make sure that you check for sound. You don’t want to hear the annoying sound the humidifier makes. Most humidifiers also come with permanent lights, so you might need a black tape to cover it up.
  • Cleaning: Shop for humidifier without lots of crannies and nooks to ensure easy cleaning. It is tricky to clean a regular humidifier, talk less of a complicated one.
  • Size: The humidifier comes in different sizes depending on the room they’ll be used in, so check for size before buying.

2. Keep plants in your bathroom

If your bathroom has a window, you should put some plants in there. Here’s why the plants will benefit from the extra humidity your shower creates.

Note: If your bathroom window is facing south, east, or west, it receives more sun and will be a good place for tropical plants. If your bathroom window is facing north, it receives less sun to be a good place for low-light plants like calatheas, pothos, spider plants, ZZ plants, and snake plants.

3. Misting plants Method

Misting comes with a lot of controversies. Some say it is bad for plants; some say it is good. But, I recommend you mist your plants with moderation.

Misting plants

The “moderation” part is where people get it wrong. Everything can be bad or good, depending on how you use it. Give each plant a light mist depending on their size, and make sure never to soak the plants entirely.

You won’t have any issues if you spray your plants with moderation, and trust me, your plants will love you for it.

3. Group plants together

Group plants together

It is recommended to group your plants to create more humidity. When you have enough plants in a part of your home, that part will be more humid, and it is good for our health and plants’ health.

4. Use pebble trays

A pebble tray is a shallow tray lined with pebbles that you can put your plant pot on. The tray can be a baking tray, plant saucer, or wide shallow bowl.

Using a pebble tray is another great way to increase humidity in small areas.

To use a pebble tray, you have to pour water over the pebbles until it reaches below the pot’s bottom. You shouldn’t put the pot inside the water but on top of it. If you place the pot inside the water, it can cause the plant to absorb too much water, which isn’t good for its health.

The major con to pebble trays is the fact you need to clean them often. How often you wash your pebble tray depends on your home’s temperature, but you should make sure to clean often.

5. Create a terrarium environment

Create a terrarium environment

Terrariums are semi-open or closed glass environment, which some plants tend to thrive in. Because the humidity in a terrarium is high, individual plants will thrive in it.

To create your terrarium, use a second-hand aquarium or a large glass jar with a lid. You can also create a DIY terrarium with a clear plastic bag around the plant, increasing the plants’ humidity.

6. Avoid hot spots

Don’t put your houseplants near any heat sources. Apart from the fact that your plants will get burnt, there is also less humidity around hot spots. If you have floor heating, make sure you raise your plants far off the ground onto a plant stand or small table.
