How Much Oxygen Does Ficus Plant Produce?

Updated: April 4, 2022

Ficus plants, also known as fig trees, are popular indoor plants that are easy to care for and have a reputation for purifying the air. One of the most significant benefits of having a ficus plant is its ability to produce oxygen. But how much oxygen does a ficus plant produce? In this article, we will explore this question and more.

Understanding Oxygen Production in Plants

Before we dive into the specifics of ficus plants, it’s essential to understand how plants produce oxygen. Through a process called photosynthesis, plants use energy from sunlight to convert carbon dioxide and water into glucose (sugar) and oxygen. This process occurs in the chloroplasts of plant cells and is critical for life on Earth.

Oxygen Production of Ficus Plants

Ficus plants are known for their excellent air-purifying abilities, but how much oxygen do they produce? According to a study conducted by NASA, ficus plants can produce approximately six milliliters of oxygen per hour per kilogram of plant weight.

While this may seem like a small amount, it’s important to remember that ficus plants are relatively small indoor plants. In comparison, a mature tree can produce hundreds of liters of oxygen per day. However, ficus plants are still an excellent addition to any indoor space and can contribute significantly to the air quality.

Benefits of Having Ficus Plants

In addition to their oxygen-producing abilities, ficus plants offer several other benefits. They are known for their ability to remove harmful toxins such as formaldehyde, benzene, and trichloroethylene from the air. These toxins can be found in common household items such as cleaning products and furniture.

Ficus plants also have a calming effect on people and can help reduce stress levels. Studies have shown that just being in the presence of plants can improve mood and increase productivity. Ficus plants are also low maintenance and easy to care for, making them an excellent plant for beginners.


Can ficus plants be harmful to pets?

Yes, ficus plants can be toxic to pets, particularly cats and dogs. The sap from the plant can cause skin irritation, and if ingested, it can cause vomiting, diarrhea, and other health issues. It’s essential to keep ficus plants out of reach of pets and to contact a veterinarian if your pet shows any signs of illness.

How often should I water my ficus plant?

Ficus plants prefer moist soil but can be sensitive to overwatering. It’s best to allow the top inch of soil to dry out before watering your ficus plant again. In general, ficus plants should be watered once a week, but this may vary depending on the humidity levels in your home.

Do ficus plants need direct sunlight?

Ficus plants prefer bright, indirect sunlight but can tolerate some direct sunlight. If your ficus plant is receiving too much direct sunlight, it may develop brown spots on its leaves. It’s best to place your ficus plant near a window that receives indirect sunlight or use a sheer curtain to filter the light.


Ficus plants are excellent indoor plants that offer numerous benefits, including oxygen production and air purification. While they may not produce as much oxygen as mature trees, they can still contribute significantly to the air quality in your home or office. With their low maintenance requirements and calming effect, ficus plants are an excellent addition to any indoor space.
