Why Are My Ficus Rubber Plant Leaves Turning Yellow?

Updated: September 12, 2022

The Ficus elastica, commonly known as the rubber plant, is a popular houseplant due to its attractive foliage and low maintenance requirements. However, yellowing leaves can be a common issue for rubber plant owners. In this article, we will explore the reasons why rubber plant leaves turn yellow and how to prevent it from happening.

Lack of Water

One of the most common reasons for yellowing leaves in rubber plants is a lack of water. Rubber plants prefer well-draining soil that is consistently moist but not waterlogged. If the soil is dry to the touch, it may indicate that the plant needs watering. On the other hand, overwatering can lead to root rot and cause yellowing leaves.

Overexposure to Sunlight

Another common cause of yellowing leaves in rubber plants is overexposure to sunlight. While rubber plants thrive in bright, indirect light, they can suffer from sunburn if exposed to direct sunlight. Sunburned leaves may turn yellow and develop brown patches or spots.

Low Humidity Levels

Rubber plants are native to tropical regions and require high humidity levels to thrive. Low humidity levels in the home can cause the leaves to turn yellow and drop. To prevent this, consider using a humidifier or placing a tray of water near the plant to increase moisture levels.

Nutrient Deficiencies

Yellowing leaves can also be a sign of nutrient deficiencies in rubber plants. Nitrogen, iron, and magnesium deficiencies can all cause leaves to turn yellow. To remedy this, consider fertilizing your rubber plant with a balanced fertilizer or adding supplements specifically designed for indoor plants.

Pests

Finally, pests such as spider mites and mealybugs can infest rubber plants and cause yellowing leaves. Inspect your plant regularly for signs of pest infestation such as webbing or sticky residue on the leaves. If you suspect your plant has pests, consider treating it with an insecticidal soap or neem oil.

How to Prevent Yellowing Leaves in Rubber Plants

Preventing yellowing leaves in rubber plants is relatively straightforward. Here are some tips to keep your plant healthy and thriving:

  • Water your rubber plant consistently, but avoid overwatering or letting the soil dry out completely.
  • Place your rubber plant in bright, indirect light and avoid exposing it to direct sunlight.
  • Increase humidity levels around your rubber plant using a humidifier or tray of water.
  • Fertilize your rubber plant regularly with a balanced fertilizer or supplements designed for indoor plants.
  • Inspect your rubber plant regularly for signs of pest infestation and treat it promptly if necessary.

By following these simple tips, you can prevent yellowing leaves in your rubber plant and keep it looking healthy and vibrant.

FAQ

Can I save yellow leaves on my rubber plant?

If the yellowing is caused by overwatering or lack of water, you may be able to save the leaves by adjusting your watering schedule. However, if the yellowing is caused by other factors such as nutrient deficiencies or pest infestation, you may need to remove the affected leaves.

How often should I fertilize my rubber plant?

You should fertilize your rubber plant every one to two months during the growing season (spring and summer). During the dormant season (fall and winter), reduce fertilization to once every three months.

Can I propagate my rubber plant from yellow leaves?

No, you cannot propagate a rubber plant from yellow leaves. Propagation requires healthy leaves with no signs of damage or disease.

How do I increase humidity levels around my rubber plant?

You can increase humidity levels around your rubber plant by using a humidifier, placing a tray of water near the plant, or grouping it with other plants to create a microclimate.
