Java Fern 'Windelov'

The Java Fern 'Windelov', a cultivar of Microsorum pteropus, is a standout in the aquarium hobby thanks to its uniquely forked, lacy leaf tips. This plant brings an elegant, bushy texture to freshwater setups. It's incredibly resilient and adaptable, making it a favorite for both newcomers and seasoned aquarists looking for a beautiful, low-maintenance fern.

Care

Java Fern 'Windelov' is exceptionally easy to care for. It thrives in low to moderate lighting and a wide range of water parameters. The most critical aspect of its care is to avoid burying the rhizome (the horizontal root-like stem) in the substrate, as this will cause it to rot. Instead, attach it to driftwood, rocks, or other decorations using thread, fishing line, or aquarium-safe superglue until its roots take hold.

Propagation

Propagation is straightforward. The fern reproduces in two main ways: by dividing the rhizome or through plantlets. To propagate by division, simply cut the rhizome into sections, ensuring each piece has several healthy leaves and roots. Alternatively, small new plantlets, complete with their own leaves and roots, will often form on the edges and tips of older leaves. Once these plantlets are large enough, they can be gently detached and attached to a new surface.

Trimming

Trimming is minimal and usually only required for aesthetic purposes. Remove any old, yellowing, or decaying leaves by cutting them close to the rhizome. This helps maintain the plant's appearance and encourages new, healthy growth. Avoid cutting the rhizome unless you are propagating the plant.

Notes, Tips, and Considerations

• Do not bury the rhizome in the substrate.
• Dark spots on the underside of the leaves are normal; they are sporangia, part of the fern's reproductive system, not a sign of disease.
• This plant is an epiphyte and draws most of its nutrients from the water column, so liquid fertilizers are beneficial.
