Java fern (Microsorum pteropus) is a popular aquatic plant in the aquarium hobby. As an avid aquarium enthusiast, I have personally grown Java fern in my tanks and witnessed its growth firsthand. In this article, I will delve into the fascinating topic of how fast Java fern actually grows and share my experiences along the way.
Java fern is known for its slow growth compared to many other aquarium plants. Unlike stem plants that can rapidly shoot up towards the water’s surface, Java fern takes its time to establish and expand. This slow growth rate is due to its unique rhizome structure.
The rhizome of Java fern is a thick, horizontal stem that grows along the substrate or attaches itself to driftwood or rocks. From this rhizome, numerous leaves emerge, forming a lush and vibrant canopy. The growth of Java fern primarily occurs through the development of new leaves and the expansion of the rhizome.
From my personal experience, I have observed that Java fern takes around 4-6 weeks to acclimate to a new tank and start showing noticeable growth. During this period, it is crucial to provide optimal conditions such as adequate lighting, nutrient-rich substrate, and regular water changes to support its growth.
Once Java fern becomes established, it can grow at a rate of approximately one new leaf every 2-3 weeks. This might not seem impressive compared to other fast-growing plants, but the beauty of Java fern lies in its longevity and hardiness.
Unlike some delicate aquarium plants that require strict maintenance and care, Java fern is incredibly resilient. It can thrive in a wide range of water parameters and lighting conditions, making it an ideal choice for beginners and experienced aquarists alike.
One of the factors that contribute to the slow growth of Java fern is its nutrient requirements. While it can extract nutrients from the water column, supplementing it with a liquid fertilizer or root tabs can help promote faster growth. Additionally, providing CO2 injection can also enhance the growth rate of Java fern.
It is important to note that Java fern should not be buried in the substrate, as this can lead to the decay of the rhizome and stunted growth. Instead, it should be attached to driftwood or rocks using fishing line or plant-safe glue.
In conclusion, while Java fern may not be the fastest-growing plant in the aquarium hobby, its slow and steady growth rate adds a sense of tranquility and balance to any aquascape. The beauty and durability of Java fern make it a cherished addition to any aquarium, and I highly recommend giving it a try in your own tank.
