# How to manage humidity for your houseplants

# **Humidity**

Understanding humidity is key to keeping your houseplants thriving instead of just surviving. 

Many tropical plants come from lush environments where the air is packed with moisture, while many succulents are adapted to life in low humidity. Some of the more forgiving houseplants are highly adaptable and tolerate a wide range of humidity levels.

## **High humidity** (60% - 80%+)

High humidity replicates dense tropical rainforests, cloud forests, and riverbanks. Air at this level can feel thick, carrying a heavy amount of moisture vapor.

Plants that require high humidity usually have thin leaves or other sensitive plant parts that dry out quickly in standard room air. Because maintaining 60% to 80% humidity in an open room is difficult or nearly impossible in standard homes (and can cause damage like mold or peeling wallpaper), enclosed environments are usually necessary.

### **Tips for maintaining high humidity**

- **Use an enclosed environment.**  
  For plants that require stable, consistently high humidity (about 80% or more), use glass terrariums, cloches, or closed glass greenhouse cabinets to trap moisture from soil and leaves without raising humidity in the rest of your home. Just make sure there is some air exchange as well.
- **Take advantage of bathrooms.**  
  For plants that enjoy high humidity but don't strictly need it, place them in bathrooms with bright windows, where temporary steam from daily showers naturally raises the moisture level. Keep in mind that this humidity level may fluctuate throughout the day.
- **Add micro-fans in enclosures.**  
  High humidity without air movement can encourage issues such as rot. When using greenhouse cabinets or terrariums, install small USB fans to keep air moving gently around the leaves.
- **Shield from drafty vents.**  
  Keep delicate species far away from heating vents, radiators, and air conditioners, which quickly strip moisture from thin leaves.

## **Normal humidity** (40% - 60%)

This is the standard range for average living spaces and serves as the sweet spot for many popular houseplants. It is also the ideal level for our comfort.

Most easy-to-care-for tropical houseplants, as well as adaptive dry-climate plants adapt well to this middle ground. Their leaves can manage standard indoor evaporation without drying out too quickly or requiring constant extra moisture or extra steps.

### **Tips for maintaining normal humidity**

- **Group plants together.**  
  Plants naturally release water vapor through tiny pores in their leaves. When you group plants together, they share this evaporating moisture and create a humid mini-climate.
- **Set up a pebble tray.**  
  Fill a shallow tray with pebbles, gravel, or perlite and pour in water until it reaches halfway up. Place your pot next to or on top of the stones. As the water evaporates, it can help raise humidity right around the foliage by a few percentage points.  
    
  **_Important:_** _Make sure the bottom of the pot stays above the water level so the roots don't sit in water and rot._  

- **Use a cool-mist room humidifier.**  
  Running a modest room humidifier on a timer can help keep a room around 40%-50% relative humidity.

## **Low humidity** (10% - 40%)

Low humidity is standard in arid climates, air-conditioned rooms, and homes heated during winter. Dry air causes water to evaporate rapidly from soil and foliage.

Plants adapted to these conditions have often evolved thick leaves, waxy or hairy coatings, or fleshy stems to store water. Because they are designed to conserve moisture, high humidity can actually cause problems for them.

### **Tips for maintaining low humidity**

- **Lower indoor humidity.**  
  If an area is too humid for your plant’s liking, run a dehumidifier or set up a fan to increase air circulation.
- **Avoid humid rooms.**  
  Plants that prefer low humidity are best placed in rooms with stable, low humidity. Avoid bathrooms, for example.
- **Give them breathing room.**  
  Unlike tropical plants that love being grouped together, space low-humidity plants out so air can move freely around them.

## Frequently asked questions

### What humidity level is considered high for houseplants?

High humidity for houseplants is typically in the range of 60% to 80% or more, replicating dense tropical environments like rainforests.

### What is the ideal humidity for most houseplants?

The ideal humidity for many popular houseplants, and the standard for average living spaces, is considered normal humidity, ranging from 40% to 60%.

### How can I provide high humidity for my plants?

To provide high humidity, use enclosed environments like glass terrariums or greenhouse cabinets, or place plants in bright bathrooms where shower steam temporarily raises moisture. Ensure some air exchange to prevent issues.

### What are some ways to maintain normal humidity for houseplants?

You can maintain normal humidity by grouping plants together to create a humid micro-climate, setting up a pebble tray, or using a cool-mist room humidifier on a timer.

### Why should I be careful with very high humidity in my home?

Maintaining 60% to 80% humidity in an open room can be difficult and potentially cause damage like mold or peeling wallpaper. Enclosed environments are often necessary for plants requiring very high, stable humidity without affecting your home.

### How can I reduce humidity around my plants if it's too high?

If an area is too humid for a plant, you can run a dehumidifier or use a fan to increase air circulation. It's also helpful to avoid placing low-humidity plants in naturally humid rooms like bathrooms.

## How to manage humidity for your houseplants

1. Determine the specific humidity needs of your plant, considering if it thrives in tropical, temperate, or arid conditions.
2. For plants needing high humidity, use enclosed environments like glass terrariums or greenhouse cabinets, or place them in bathrooms with bright windows.
3. For plants thriving in normal humidity, group them closely together, set up a pebble tray, or use a cool-mist room humidifier.
4. For plants preferring low humidity, run a dehumidifier, use a fan to increase air circulation, or place them in rooms with naturally low and stable humidity.
5. Ensure good air circulation, especially in high humidity environments, to prevent issues such as rot.
6. Shield delicate plants from drafty vents, radiators, and air conditioners, as these can quickly strip moisture from leaves.
