Do Rubber Plants Like Humidity


Welcome to my comprehensive guide on the humidity preferences of rubber plants, where we answer the important question, “Do Rubber Plants Like Humidity?”

If you’re a proud owner of a rubber plant or considering bringing one into your home, understanding its humidity requirements is essential for its overall health and well-being.

In this article, I will explore the relationship between rubber plants and humidity, discussing the ideal humidity levels for these tropical beauties and the impact of humidity on their growth and foliage.

Getting Rubber Plant Humidity Right

Do Rubber Plants Like Humidity

Maintaining the right humidity levels for Your rubber plant is important for its health and growth. Here are a few tips for getting the humidity right for your rubber plant:

Place Your Rubber Plant Near a Humidifier Or a Pebble Tray

A pebble tray is a shallow tray filled with water and pebbles. Place the rubber plant’s pot on top of the pebbles and the water will evaporate, increasing the humidity around the plant.

You can also place your rubber plant near a humidifier to provide it with the necessary moisture.

Group Plants Together

Rubber plants thrive in high-humidity environments, so grouping them with other plants can help create a more humid environment for all of them.

Avoid Placing Your Rubber Plant Near Heat Sources

Heating vents, radiators, and fireplaces can cause the air around your rubber plant to become dry and can affect its health. Make sure to place your rubber plant away from these sources of heat.

How Often to Mist a Rubber Plant?

How often you mist a rubber plant depends on how humid it is and how hot it is. Rubber plants like humidity between 40 and 60%.

If your home is dry, give your plant a spritz of water once or twice a week. If you live in a humid area, your plant may not need to be misted.

Temperature is also important. Due to the heat and dry air, your plant may need more misting in the Winter. But the naturally humid air of summer may mean that less misting is needed.

Bigger rubber plants may need less misting. The best way to tell if your rubber plant needs water is to look at its leaves. Spritz if it’s dry and brown. If they are green and healthy, humidity is enough.

Signs Your Rubber Plant Needs More Humidity

Signs your rubber plant needs more humidity

Here are some Common signs that your Rubber plant May need more humidity:

  • Crispy or brown leaf edges: If the edges of the Leaves on your rubber plant are starting to turn brown and crispy, it may be a sign that the air is too dry for the plant.
  • Dry, brittle leaves: If the leaves on your rubber plant feel dry and brittle to the touch, it’s another sign that the air is too dry.
  • Leaf drop: If your rubber plant is losing more leaves than usual, it may be due to a lack of humidity.
  • Slow growth: Rubber plants need a certain level of humidity to grow properly. If your plant is not growing as quickly as it should, it may be due to low humidity levels.
  • Yellowing leaves: If the leaves on your rubber plant are turning yellow, it may be a sign of stress caused by low humidity levels.

If you notice any of these signs, try increasing the humidity around your rubber plant. You can do this by misting the leaves regularly, placing a humidifier nearby, or grouping your plants together to create a more humid microclimate.

How to Check the Humidity in Your Home?

There are several ways to check the humidity in your Home:


This is a device specifically designed to measure humidity. You can purchase a hygrometer at most hardware or home improvement stores.

Thermometer and Humidity Chart

If you have a thermometer, you can use a humidity chart to estimate the relative humidity. Simply measure the temperature in your home and find the corresponding relative humidity on the chart.

Wet and Dry Bulb Thermometer

This is a more advanced tool that measures Both the temperature and the relative Humidity. The device consists of two thermometers, one with a Wet wick and one with a dry wick.

Your Senses

You can also get a rough estimate of the humidity in your home by simply observing how You feel.

If the air feels dry and your skin is dry, the air is likely low in humidity. If the air feels humid and your skin is damp, the air is likely high in humidity.

It’s important to note that the humidity levels can vary from room to room, so you may need to check the humidity in each room where you have plants.

Humidity Preferences of Rubber Trees

While this rubber tree is a tropical plant that comes from humid conditions It is not particularly concerned with fluctuations in humidity levels within the house.

Generally speaking, as long as your plant gets sufficient indirect, bright light and isn’t excessively frigid (it prefers temperatures ranging from 65deg to 80deg and never dropping below 50deg) It will reward you with constant growth.

The average indoor humidity for the majority of homes is between 40 and 50 percent, which is inside of the rubber tree’s acceptable limits.

If you notice that your rubber tree’s tips becoming brown after having considered the other factors that affect your tree low humidity could be the cause you’ll need to find out how you can solve it.

Where to Place a Rubber Tree in Your Home

When choosing a spot for your rubber tree, look for a location that receives bright, indirect light. A north or east-facing window is often ideal, as it provides gentle morning or filtered light.

You can also place your rubber tree a few feet away from a west or south-facing window to avoid direct sunlight. Avoid placing it in a dark corner or areas with drafty conditions.

The temperature should be consistent, ideally between 60-75°F (15-24°C). Additionally, make sure there is enough space for the plant to grow and spread its leaves without being obstructed by nearby furniture or walls.

How to Increase Humidity Around Your Rubber Tree?

To increase humidity around your rubber tree, you can employ several methods. One option is to place a tray or saucer filled with water near the plant. As the water evaporates, it creates moisture in the air.

You can also use a humidifier in the room where the rubber tree is located. Another technique is to group your plants together, as they release moisture through transpiration, collectively increasing the humidity.

Additionally, misting the leaves of the rubber tree with water can provide a temporary boost of humidity.

Lastly, placing the plant in a bathroom or kitchen, where humidity levels are naturally higher, can also help maintain adequate moisture for your rubber tree.


In conclusion, rubber plants require a certain level of humidity to thrive. By observing the signs of low humidity and regularly checking the humidity level in your home, you can ensure that your rubber plant is getting the care it needs.

With proper care, your rubber plant can grow strong and healthy for many years to come. Read the guide above for more information and let us know what You think in the comments section. Thank you
