What is Java Fern?

Java Fern is an aquatic plant that is native to many tropical regions, including South America, Hawaii, and India. It is a popular choice for aquariums, ponds, and other water features due to its hardiness, simplicity, and low-maintenance care requirements. Java Ferns can be grown in a variety of water conditions, from completely submerged in water to partially submerged with its roots exposed. With its unique, arrow-shaped leaves and its easy-care requirements, Java Ferns are a popular choice for both beginners and experienced aquarists alike.

Selecting Quality Plants

When selecting Java Ferns for your aquarium, look for plants that are healthy and free of damage. Healthy plants will be bright green, with no yellowing leaves or discoloration. The rhizome (roots) should be firmly attached to the plant and the leaves should be free of algae, snails, and other pests. When buying Java Ferns, avoid buying plants that are already attached to driftwood or rocks. These plants are usually harvested from the wild, and may carry unwanted pests or diseases.

Planting Java Ferns

Java Ferns can be planted in a variety of ways, depending on the look and feel you want for your aquarium. The most popular way to plant Java Ferns is by attaching them to driftwood or rocks, using fishing line or thread. Attaching them to these objects will give them more stability and help them to establish themselves more quickly. You can also plant them in the substrate, with their rhizome buried and the leaves exposed. Whichever way you decide to plant them, make sure that the rhizome is completely covered with substrate. The rhizome is the part of the plant that needs to be kept moist, so make sure that it is completely covered.

Light and Water Conditions

Java Ferns prefer bright, indirect lighting. Direct sunlight should be avoided, as this can cause the leaves to burn and turn brown. The water temperature should be kept at a steady temperature of 70-78°F (21-26°C). Java Ferns can tolerate a wide range of water conditions, from soft to hard water, and pH levels from 5.5-7.5. Java Ferns should also be given regular water changes, as this will help to keep the water clean and free of pollutants.

Fertilizers and Nutrients

Java Ferns do not require any special fertilizers or nutrients. They are able to absorb the necessary nutrients from the water column and from the substrate. If you want to give your Java Ferns a boost, you can add a small amount of liquid fertilizer once a month. This will help to keep them healthy and vibrant.

Pruning and Trimming

Java Ferns do not need to be pruned or trimmed very often. When they do need to be pruned, it is best to use a pair of scissors or tweezers to remove dead or damaged leaves. Pruning will help to keep the plant looking its best and will also help to promote new growth. Make sure to sterilize the scissors or tweezers before and after pruning, as this will help to avoid the spread of any diseases.


Java Ferns reproduce through vegetative propagation, which means that they can produce new plants from their existing rhizomes. The best way to propagate Java Ferns is to separate the rhizome into smaller pieces and then replant them in separate containers. This will give each piece a chance to establish itself before being planted in the aquarium. Once the rhizomes are established, they can be planted in the aquarium in the same manner as the original plant.

Common Pests and Diseases

Java Ferns are generally hardy and are not prone to many diseases or pests. The most common pests are snails, algae, and aphids. Snails can be removed manually or with the use of a snail trap. Algae can be controlled with the use of an algae-eating fish, such as a Siamese Algae Eater. Aphids can be removed by spraying the leaves of the plant with a mixture of water and a few drops of dish soap.


Java Ferns are a great choice for aquatic gardens and aquariums, due to their easy-care requirements and hardiness. With proper care, they will thrive and provide your aquarium with a beautiful backdrop. When selecting Java Ferns, look for healthy plants that are free of pests and diseases. Plant them in a variety of ways and make sure to keep the rhizome covered with substrate. Java Ferns prefer bright, indirect light and a steady temperature of 70-78°F (21-26°C). They do not require any special fertilizers or nutrients, but you can add a small amount of liquid fertilizer once a month to give them a boost. Prune and trim them occasionally, and propagate them through vegetative propagation. By following these tips, you will be able to grow healthy, vibrant Java Ferns.
