Introduction
Java fern is one of the most popular aquarium plants among fish keepers. It is easy to care for and adds a lot of beauty to the tank. Java fern is a low-light tolerant plant, and can grow in a wide range of water conditions. It is also relatively hardy and can survive in temperatures as low as 60 degrees Fahrenheit and as high as 80 degrees Fahrenheit. But how tall does Java fern grow?
How Tall Does Java Fern Grow?
The answer to this question depends on the variety of Java fern that you have. Some varieties are smaller than others, and some can grow to be very tall in the right conditions. Generally, the standard Java fern will grow to be around 10 inches tall, with some reaching up to 12 or even 15 inches in height. Other varieties such as the narrow leaf Java fern may only grow to be 6 to 8 inches tall.
Where Does Java Fern Grow?
Java fern is an aquatic plant, so it will grow in any body of water. It is most commonly found in streams, ponds, and other slow-moving water sources. It can also grow in tanks and aquariums, as long as the water conditions are suitable. The ideal water temperature for Java fern is between 65 and 80 degrees Fahrenheit. It can also tolerate a wide range of pH levels, from 5.5 to 8.0.
How To Care For Java Fern
Caring for Java fern is relatively easy. The plant should be planted in a substrate that is low in nutrients, such as sand or gravel. Java ferns can also be left to float freely in the tank. The plant should be given adequate lighting, but it can tolerate low-light conditions. Fertilizers and CO2 injections are not necessary for Java ferns, but adding them can help the plant grow faster.
Pruning Java Fern
Java ferns will naturally grow very tall, and may need to be pruned regularly to keep them from becoming too large. Pruning should be done carefully, as the leaves of the plant are very fragile and can be easily damaged. To prune, use scissors or a sharp knife to cut off any dead or dying leaves. It is also a good idea to remove any offshoots that develop on the plant, as these can quickly become overgrown.
Propagating Java Fern
Java ferns are very easy to propagate, and this is a great way to get more of the plant without having to buy new ones. To propagate, simply remove any offshoots that form on the parent plant and replant them in the substrate. Alternatively, the offshoots can be left to float freely in the tank. Within a few weeks, the offshoots will begin to form their own roots and can then be planted in the substrate.
Conclusion
Java fern is a great plant for aquarists of all levels. It is easy to care for and adds a lot of beauty to the tank. The plant can grow to be quite tall, but can easily be kept in check with regular pruning. The plant can also be easily propagated, making it a great choice for those just starting out with aquariums.
