How to Water a Rubber Plant: Essential Tips and Guidelines

Rubber plants (Ficus elastica) are popular houseplants known for their attractive foliage and easy care requirements. Proper watering is crucial to keep your rubber plant healthy and thriving. 

In this article, we’ll share essential tips and guidelines to ensure you give your rubber plant the right amount of water it needs. So why the delay?

Understanding the Watering Needs of a Rubber Plant

Before diving into the specifics of watering your rubber plant, it’s important to understand its natural habitat and watering requirements. Rubber plants are native to the tropical regions of Southeast Asia, where they grow in rainforests with high humidity levels. Mimicking these conditions in your home is key to providing optimal care for your plant.

Rubber plants have moderate water needs and prefer consistent moisture, but they also don’t like to sit in soggy soil. Overwatering can lead to root rot and other problems, while underwatering can cause the leaves to droop and eventually drop.

When to Water Rubber Plants

To determine when your rubber plant needs watering, you can use the finger test. Insert your index finger about an inch deep into the soil near the base of the plant. If the soil feels dry at that depth, it’s time to water.

However, if it still feels slightly moist, wait a few more days before watering. It’s important to note that the watering frequency may vary depending on various factors such as the size of your pot, the temperature and humidity in your home, and the season. 

During the active growing season (spring and summer), your rubber plant may need more frequent watering compared to the dormant period (fall and winter).

Watering Techniques For Rubber Plants

When it comes to watering your rubber plant, it’s best to use room temperature water. Cold water can shock the roots, while hot water can scorch them. Here are two effective techniques for watering your rubber plant:

The Soak and Dry Method

The soak and dry method is a popular approach for watering houseplants, including rubber plants. Here’s how to do it:

  • Place your rubber plant in a sink or bathtub.
  • Slowly pour water onto the soil until it starts to drain out of the bottom of the pot.
  • Allow the plant to soak up the water for about 15-20 minutes.
  • Once the time is up, discard any excess water that has accumulated in the saucer or tray.

This method ensures thorough hydration while allowing any excess water to drain away, preventing waterlogging.

Bottom Watering

Another effective technique is bottom watering, which involves placing the pot in a saucer or tray filled with water. The plant will absorb water through the drainage holes at the bottom of the pot.

Allow the plant to soak up the water for about 15-20 minutes, and then remove the pot from the saucer, discarding any remaining water. Bottom watering is especially useful if you have a rubber plant in a decorative pot without drainage holes, as it reduces the risk of overwatering.

Using a Watering Can

Using a watering can is a straightforward and convenient method for watering your rubber plant. Here’s how to do it

  • Fill a watering can with room temperature water.
  • Position the spout of the watering can close to the base of the rubber plant.
  • Gently pour water onto the soil, allowing it to soak in.
  • Continue watering until you see water trickling out of the drainage holes at the bottom of the pot.
  • Wait for a few minutes to allow any excess water to drain away, and then discard it from the saucer or tray.

Using a watering can provides you with control over the amount of water you give to your rubber plant, ensuring you don’t overwater it.

Drench and Dry Method

The drench and dry method involves thoroughly saturating the soil and allowing it to dry out before watering again. Here’s how you can use this technique:

  • Place your rubber plant in a sink or bathtub.
  • Slowly pour water onto the soil, making sure to wet the entire root ball.
  • Continue watering until you see water draining out of the bottom of the pot.
  • Allow the excess water to drain completely before returning the plant to its regular location.

Wait for the soil to dry out partially before watering again. You can use the finger test to assess the moisture level.

This method ensures that the roots receive a thorough watering while also allowing for proper drying between waterings, preventing waterlogging.

Ice Cube Watering

The ice cube watering method is a convenient way to provide slow and controlled hydration to your rubber plant. Here’s how you can use this technique:

  • Place a few ice cubes on the surface of the soil around your rubber plant.
  • Allow the ice cubes to melt gradually, releasing water into the soil.
  • Monitor the soil moisture and adjust the number of ice cubes based on the needs of your plant.

Using ice cubes provides a slow-release watering method, preventing the risk of overwatering while ensuring consistent moisture levels for your rubber plant.

Essential Healthcare Tips for Rubber Plants

Proper Drainage

Ensuring proper drainage is essential for the health of your rubber plant. Rubber plants don’t tolerate sitting in standing water, as it can lead to root rot. Make sure your plant’s pot has drainage holes to allow excess water to escape. 

If your pot doesn’t have drainage holes, consider transferring your plant to a pot that does or use the bottom watering method mentioned earlier.

Humidity and Mist

As mentioned earlier, rubber plants prefer high humidity levels due to their tropical origins. While they can tolerate average room humidity, providing additional moisture can benefit their overall health and appearance. You can increase humidity by:

  • Placing a tray of water near the plant.
  • Misting the leaves with water once or twice a week.
  • Using a humidifier in the room where your rubber plant is located.

Seasonal Adjustments

During the active growing season, your rubber plant may require more water due to increased evaporation. Adjust your watering frequency accordingly, always keeping an eye on the soil moisture.

In winter, when the plant goes into a dormant phase, reduce watering to avoid overhydration.

Frequently Asked Questions (FAQs)

How often should I water my rubber plant?

The frequency of watering depends on various factors such as temperature, humidity, pot size, and the specific needs of your plant. As a general guideline, you can check the soil moisture by using the finger test. Water your rubber plant when the top inch of soil feels dry. 

Can I overwater my rubber plant?

Yes, overwatering can be detrimental to your rubber plant’s health. Rubber plants prefer consistent moisture but don’t like to sit in soggy soil. Overwatering can lead to root rot, yellowing leaves, and even the death of the plant. It’s important to check the soil moisture before watering and ensure proper drainage to prevent waterlogging.

Can I use tap water to water my rubber plant?

Tap water is generally fine for watering rubber plants. However, if your tap water is heavily chlorinated or has a high mineral content, it’s best to let it sit out overnight or use filtered water. This allows the chlorine to dissipate and reduces the risk of mineral buildup in the soil, which can affect the plant’s health over time.

Should I mist my rubber plant’s leaves?

While rubber plants can tolerate average root humidity, misting their leaves can be beneficial, especially in drier environments or during the winter months when indoor humidity tends to be lower. Misting can help increase humidity around the plant and prevent the leaves from drying out. Aim to mist the leaves once or twice a week, avoiding excessive moisture that can promote fungal diseases.

What should I do if I accidentally overwater my rubber plant?

If you accidentally overwater your rubber plant and notice signs of waterlogging, such as wilting, yellowing leaves, or a foul odor, take immediate action. Remove the plant from its pot and examine the roots. Trim away any mushy or rotten roots, and repot the plant in fresh, well-draining soil. Allow the plant to dry out and adjust your watering habits to prevent future overwatering incidents.


Properly watering your rubber plant is vital for its well-being. Remember to assess the soil moisture using the finger test, employ effective watering techniques such as the soak and dry method or bottom watering, ensure proper drainage, and consider increasing humidity levels when needed.

By following these guidelines, you’ll provide the optimal watering conditions for your rubber plant, allowing it to thrive and beautify your home for years to come. Happy gardening.
