Yes, you can grow Java fern out of the water. This hardy plant can tolerate a wide variety of conditions. Java fern can thrive, whether it’s fully submerged, immersed, or completely out of the water.
However, you need to remember that Java fern loves water and humidity, so you should ensure its root system and rhizomes are constantly in contact with water.
Additionally, even if you grow it outside of water, a Java fern’s rhizome must never be buried in the soil. Otherwise, it won’t be able to absorb any nutrients, causing the plant to rot slowly.
