While you can remove unsightly leaves to improve the overall appearance, there are good reasons to leave them when possible. Once placed in its new space, you may notice the Java fern’s leaves growing brown and mushy looking. Many Java ferns grown for cultivation are grown “emersed,” or only partially submerged, so the transfer to a fully aquatic environment takes some getting used to.ĭifferences in lighting can also trigger burn or die back as the plant produces new growth that’s better suited to its new environment. When you add a Java fern to a new tank, chances are the environment will be considerably different from its original growing space.
Adjusting factors such as lighting, nutrient levels, or planting method, and removing any overgrowth of blue-green algae, should allow your plant to recover completely. If an established plant is starting to turn brown, something is likely off in its environment, as Java ferns are very resistant to disease. It’s not uncommon for them to die back almost completely before springing back good as new.
Java ferns require a period of adjustment when added to a new tank or environment. Thankfully, most of these issues are easily resolved! While they’re generally hardy and easy to grow, occasionally they can experience issues that leave them looking mushy, brown, and unappealing.
Java ferns are a beautiful addition to just about any freshwater aquarium or aquatic vivarium since they can grow either partially or fully immersed in water.
