Ficus plants, also known as fig trees, are popular houseplants that are renowned for their lush green foliage and air-purifying abilities. One of the main benefits of having a ficus plant in your home is that it produces oxygen. But just how much oxygen does a ficus plant produce? In this article, we will explore the fascinating world of ficus plants and learn about their oxygen-producing capabilities.

Understanding Oxygen Production in Plants

Before we dive into the specifics of ficus plants’ oxygen production, it’s important to understand how plants produce oxygen. Through a process called photosynthesis, plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

During photosynthesis, plants absorb carbon dioxide from the air through tiny pores called stomata on their leaves. They then use energy from sunlight to break down the carbon dioxide and water molecules and reassemble them into glucose and oxygen. The glucose is used by the plant as food, while the oxygen is released back into the air.

Oxygen Production in Ficus Plants

Ficus plants are one of the best-known examples of air-purifying plants that can help improve indoor air quality. They are known to absorb harmful chemicals and pollutants from the air, making them an excellent addition to any home or office.

In terms of oxygen production, ficus plants are not the most efficient. On average, a mature ficus plant produces between 5-10 milliliters of oxygen per hour. This may not seem like much, but when you consider that a single person requires around 550 liters of oxygen per day, every little bit helps.

Factors Affecting Oxygen Production in Ficus Plants

The amount of oxygen produced by a ficus plant can vary depending on several factors. One of these factors is light exposure. Ficus plants require bright but indirect light to grow properly and produce oxygen. If they are not getting enough light, their oxygen production may be reduced.

Another factor that can affect oxygen production in ficus plants is temperature. They prefer warm, humid conditions and may struggle to produce oxygen in cooler or drier environments.

Finally, the size of the plant can also affect its oxygen production. Larger plants have more leaves and therefore more stomata, which means they can absorb more carbon dioxide and produce more oxygen.

Other Benefits of Ficus Plants

While ficus plants may not produce as much oxygen as other plants, they still offer many other benefits. For example, they are excellent at absorbing harmful chemicals and pollutants from the air, making them a great choice for improving indoor air quality.

Ficus plants are also known for their beautiful foliage, which can add a touch of natural beauty to any room. They are relatively easy to care for and can thrive in a variety of indoor environments.

Frequently Asked Questions

Can ficus plants be harmful to pets?

Yes, ficus plants can be toxic to pets if ingested. The sap of the plant contains a chemical called ficin, which can cause vomiting, diarrhea, and skin irritation in pets. If you have pets in your home, it’s important to keep ficus plants out of reach or consider choosing a pet-safe alternative.

How often should I water my ficus plant?

Ficus plants prefer moist soil but can be sensitive to overwatering. It’s best to water them only when the top inch of soil feels dry to the touch. Be sure to drain any excess water from the pot after watering to prevent root rot.

Can ficus plants be grown outside?

Yes, ficus plants can be grown outdoors in warm climates with mild winters. They prefer well-draining soil and partial shade but can tolerate full sun with proper care.


Ficus plants are an excellent choice for anyone looking to improve indoor air quality and add a touch of natural beauty to their home or office. While they may not produce as much oxygen as some other plants, they are still a valuable addition to any indoor environment. By understanding how ficus plants produce oxygen and the factors that affect their production, you can ensure that your plant is healthy and thriving.
