What is the Ideal Fertilizer?

Fiddle leaf figs are popular ornamental trees that are native to subtropical and tropical gardens. Because of their unique, banjo-like leaves that grow up 18 inches long and 12 inches broad, they act as a striking centerpiece to any home. Furthermore, their leaves show prominent veins and a leathery texture. They are popular among interior designers and also gained the Royal Horticultural Society’s Award of Garden Merit.

Because of their big green foliage, they require fertilizers that are high in nitrogen content, which helps encourage grean, leafy growth. They grow most robustly with an NPK ratio of 3-1-2.

The quality of the product for a plant is typically dependent on two main factors. The first factor is NPK ratio and the second factor is the quality of the ingredients. Ultimately, a good product will help your tree grow strong and healthy while also promoting proper root growth.

Banjo Fig Care Overview

Fiddle leaf fig trees are popular and beautiful trees. They make a beautiful, architectural statement in just about any place that you put it in your house. Its shiny, long, green leaves are quite striking. They can be difficult to keep alive though. To ensure success, you should follow these tips below.

Appropriate Amounts of Light

As with any plant, receiving enough sun is important for fiddle leaf figs. Place your tree in an eastward facing window. If you notice that your plant is leaning at all, you will want to rotate it so that it does not lean excessively in any one direction.

Be careful of westward and southward facing windows. Direct sun can cause the leaves to burn. Even though the fiddle leaf fig is native to areas that have full sun, they also have protection from nearby canopy.

Deep Watering

As with many plants, deep watering of the soil is preferred. Leaving your tree in moist soil constantly will increase the risk of developing diseases. Instead, try to water deeply by giving water until it drains into the bottom saucer. If the water level is high in the saucer, you will want to drain the saucer. Only give water when the top inch of soil becomes dry. You can test this by gently pressing into the soil about an inch deep to see if it is moist. You generally only will want to water once per week at most, sometimes possibly even once every two weeks. You can also start picking up a pot with dried soil vs wet soil, to start to get a feel for how light the pot feels like when it is dry. 

It is also best to use well draining soil. If you don’t have well draining soil, consider using it the next time you repot your tree. Remember that you should aim to repot in the Spring and to avoid repotting in the winter. 

Imitating Its Natural Climate

Fiddle leaf figs are typically found in areas of warmer, more humid climate. They thrive perfectly well in a house but try to avoid placing them close to windows that may have constant cold drafts. In the winter when it is very dry, you can also consider misting (very sparingly) around the leaves to simulate a humid environment.


The ideal N-P-K ratio is 3-1-2. Fertilize your plant once during the spring and monthly throughout the summer. Be careful not to overdo it. Giving too much nutrients can cause as many issues as not giving enough. During the winter months, the plant slows down its natural growth, so it does not need additional nutrients.

Wipe Off the Dust

Fiddle leaf fig leaves collect dust. When you notice dust collecting, gently wipe it away with a damp cloth. Not only will this make your plant appear more striking, it will also help it be able to optimize its photosynthesis.

Do Not Ingest

Even though I do not know anyone that tries to eat their trees, we thought it would be worth it to bring up this warning. Be careful because the leaves are mildly toxic to humans and pets. Ingestion can cause some mouth and gastrointestinal irritation that also might lead to vomiting.

FIddle leaf fig makes a great design piece in any room.
