![]() ![]() If too much of the leaf surface is exposed to the air, it may require additional nutrients to sustain itself properly.įern microsorum pteropus can survive living in brackish, salty water but prefers fresh water. When it comes to general java fern care, it will thrive if completely submerged in a fish tank or a pond, although the tips of its leaves can rise over the water’s surface. Water and HumidityĪs java fern microsorum is an aquatic plant which can grow fully submerged in planted aquarium, it’s safe to say that it loves humidity! This holds true whether it’s fully or partially submerged, and its root system and rhizome should be in contact with water constantly for best growth. Temperature-wise, java ferns love temperatures in the 70-75 degree range, but can tolerate anything from 60-83 degrees Fahrenheit. If this still seems to be too much light, consider back-lighting the tank with low-light LEDs and reducing your upper lighting even more. This can cause brown patches to appear, or in really severe cases the leaves will go transparent and begin to dissolve.Ī reasonable rule of thumb is to aim for 1.5 watts of soft lighting for each gallon of water in the tank, using small incandescent lights or soft fluorescents. Too much light, and your plant’s leaves will get burned. Whereas many plants love lots of sunlight, your java fern microsorum is actually a low-light plant. Let’s go over care conditions for your java fern and how you can successfully grow java fern! Light and Temperature ![]() But it’s unlike many other sorts of plants. Java Fern CareĬonsidered among the easiest aquarium plants to grow, java fern is a fantastic addition to your planted aquarium. Pointed tips widen dramatically on the upper portion of the leaf, then gradually decrease until the leaf vanishes into the rhizome at its base. Undulata is an interesting variety in that its leaves tend to be almost the reverse of the shape of the Narrow variety’s leaves. It’s best described as an extremely elongated teardrop shape, and it’s slightly textured in a similar way to the Philippine java fern. Slightly wider towards the leaf base than Trident is, Narrow has a similarly-flowing long and tapered leaf shape. This is what a lot of people think of when they think of underwater plants – long, swaying fronds which join together close to the rhizome. Trident has needle-like feathery leaves that sway in the water in an appealing way. This variety is quite popular, but can be difficult to find. Philippine, ‘Philippine Java Fern’Ī broad-leaved variety, it is distinctive in that its leaf surfaces appear to be hammered. Due to its finer leaves, this also tends to be a shorter plant. Delicate and feathery, the windelov variety can be used in conjunction with broader-leafed varieties for visual appeal. This is sometimes called “lace java fern” because of its fine leaf shape. Microsorum pteropus var. Windeløv, ‘Windelov Java Fern’ There’s multiple different fern microsorum types out there. While the length of the leaves is somewhat variable, these often reach 13″ or more in length, so are often used towards the rear of an aquarium. The leaves also form the reproductive portion of the plant, as they can form spores and develop plantlets directly on the leaf surfaces. Some are narrow leaf fern varieties, like the needle leaf fern, and others have a less narrow leaf. They vary in shape depending on the plant’s origin and growing conditions. Leathery, dark-green leaves form the rest of the plant. Over time, the rhizome will grow to cover whatever object the plant has grabbed onto, and can easily spread to reach 6″ wide. This rhizome forms the base of the plant and absorbs most of the plant’s required nutrition from the water around it. These super-fine, hairlike tendrils do a great job of it. Instead of its root system, the fern absorbs nutrients with these as much as they’re used for simply hanging on. Tendril-like dark brown roots are used to attach the plant to its chosen medium. ![]() These plants consist of three basic parts: a root system, a rhizome, and the leaves. In the wild, these java ferns grow both submerged in water and partially above the surface, dwelling in boggy areas or along waterways. With a natural habitat originating in Thailand, parts of China, and Malaysia, Microsorum pteropus is a variable water-loving plant. What this aquatic plant looks like out of water. ![]()
