Rubber Plant Too Tall?: How to Manage and Control Its Height

Rubber plants (Ficus elastica) are popular indoor plants known for their attractive glossy leaves and ability to thrive in a wide range of conditions. However, sometimes these plants can become too tall for their surroundings, causing concerns for homeowners. 

Understanding why your rubber plant is growing excessively tall can help you address the issue effectively. In this article, we will find out why your rubber plant grows too tall and how to fix it. So let’s get started.

Why is your rubber plant growing too tall

Natural growth habit

Rubber plants have a natural tendency to grow upright, seeking light and space. In their native habitat, these plants can reach impressive heights, but indoors, they may outgrow their designated space quickly. Their growth rate can vary depending on factors such as light availability, temperature, and overall care.

Insufficient light

Insufficient light is a common reason why rubber plants stretch and become leggy. If your plant isn’t receiving enough bright, indirect light, it will elongate in an attempt to find more light. This can result in a tall, lanky appearance with sparse foliage.

Improper pruning

Pruning plays a crucial role in managing the height and shape of a rubber plant. If the plant is not pruned correctly or regularly, it can lead to excessive vertical growth. Pruning encourages lateral branching, which helps create a fuller, bushier appearance.


Overfertilization can stimulate rapid growth in rubber plants, causing them to become taller than desired. It’s important to follow the recommended fertilization schedule and use a balanced houseplant fertilizer at half-strength to avoid excessive growth.

Managing the Height of Your Rubber Plant

Pruning for height control

To manage the height of your rubber plant, regular pruning is essential. Here are some steps to follow:

Identify the desired height

Determine the ideal height you want your rubber plant to maintain. This will guide you in deciding how much to prune.

Selective pruning

Identify the tallest stems or branches that contribute to the excessive height. Using clean, sharp pruning shears, make a clean cut just above a node or leaf. This will encourage lateral branching and promote a bushier growth habit.

Prune regularly

Regularly monitor your rubber plant’s growth and prune any new growth that surpasses the desired height. By maintaining a consistent pruning routine, you can prevent your plant from becoming too tall.

Providing adequate light

Proper lighting is crucial for a healthy rubber plant and can help control its height. Here are some tips for ensuring your plant receives sufficient light:

Find a bright location

Place your rubber plant near a window that provides bright, indirect light. Avoid direct sunlight, as it can scorch the leaves.

Rotate the plant

Rotate your rubber plant every few weeks to ensure even exposure to light on all sides. This will help prevent the plant from leaning towards the light source and growing unevenly.

Consider supplemental lighting

If natural light is limited in your space, you can supplement it with artificial grow lights. LED grow lights are an excellent option, providing the right spectrum of light for optimal plant growth.

Proper watering and fertilization

Maintaining a consistent watering and fertilization routine is important for overall plant health. Avoid overwatering, as excessively moist soil can hinder the plant’s growth. Additionally, follow a balanced fertilization schedule to prevent overstimulation of growth.

Common Concerns with Tall Rubber Plants

Stability and Support

As rubber plants grow taller, their stems may become top-heavy and less stable. This can lead to the plant leaning or even tipping over, potentially causing damage to the plant and surrounding objects. Providing support, such as a stake or trellis, can help keep the plant upright and prevent it from toppling.

Aesthetics and Space Limitations

Tall rubber plants can overpower a room and create an imbalanced aesthetic. If your plant has outgrown its designated space or is obstructing views or pathways, it may be necessary to address its height to maintain a visually pleasing and functional environment.

Difficulty in Care and Maintenance

Managing the care and maintenance of tall rubber plants can be more challenging compared to smaller plants. Watering, pruning, and dusting the leaves become more cumbersome as the height increases. Controlling the plant’s height can make these tasks more manageable and ensure the overall health of the plant.

Additional Tips for Controlling the Height of Rubber Plants

Air Layering

If your rubber plant has become excessively tall and pruning alone isn’t sufficient, you can try air layering. Air layering involves creating a wound on a stem and encouraging the development of roots at that point.

Once roots have formed, you can cut the stem below the rooted section, effectively creating a new, shorter plant. This method allows you to control the height while also propagating a new rubber plant.

Repotting and Root Pruning

Another approach to managing the height of a rubber plant is through repotting and root pruning. When repotting, choose a slightly smaller pot size to restrict the root growth. Additionally, gently prune the roots during repotting to prevent them from becoming overly extensive. This practice helps limit the plant’s overall growth and size.

Training and Shaping

Training and shaping your rubber plant from an early stage can help control its height and create a desired form. As the plant grows, gently bend and secure the stems in the desired direction using soft ties or plant clips. This method encourages horizontal growth and prevents excessive vertical growth.

Frequently Asked Questions

Can I cut the top off my rubber plant to control its height?

While you can prune your rubber plant to control its height, simply cutting off the top may not be the best approach. Drastic pruning can result in an unbalanced and unsightly appearance. It’s better to selectively prune taller stems or branches just above a leaf or node to encourage lateral growth and maintain a more natural form.

How often should I prune my rubber plant to manage its height?

The frequency of pruning depends on the growth rate of your rubber plant and your desired height. It’s generally recommended to prune regularly, ideally every few months, to maintain the plant’s desired height and shape. Regular monitoring of new growth will help you identify when pruning is needed.

Can I use pruning shears to prune my rubber plant?

Yes, pruning shears are suitable for pruning rubber plants. Make sure the shears are clean and sharp to ensure clean cuts. Avoid using blunt or dirty tools that can cause damage or introduce infections to the plant. Sterilizing the pruning shears before and after use is also a good practice to prevent the spread of diseases.

How can I provide support to my tall rubber plant?

If your rubber plant is top-heavy and needs support, you can use stakes or trellises to provide stability. Place the stake or trellis near the base of the plant and gently tie the stems to the support structure using soft ties or plant clips. This will help keep the plant upright and prevent it from leaning or falling over.

Can I control the height of my rubber plant by adjusting the light levels?

While light levels can influence the growth of rubber plants, adjusting the light alone may not be sufficient to control their height. Rubber plants require bright, indirect light for optimal growth, but if they receive insufficient light, they may stretch and become leggy. 

 Is repotting effective in managing the height of a rubber plant?

Repotting alone is not primarily used to manage the height of a rubber plant. It is more commonly done to refresh the soil, provide necessary nutrients, and allow the roots to grow. However, if you choose a slightly smaller pot size during repotting, it can help restrict root growth and indirectly control the overall size and height of the plant.


While rubber plants have a natural inclination to grow tall, there are several ways to manage and control their height. By understanding the reasons behind excessive growth and implementing appropriate measures such as pruning, providing adequate light, and maintaining proper care, you can keep your rubber plant at a desirable height while enjoying its beauty and benefits in your indoor space. 

Remember, with a little care and attention, your rubber plant will thrive and bring a touch of green to your home.
