Windelov Fern care guide
Windelov Fern (Microsorum pteropus 'Windelov') — low light, 20-28 °C, pH 6-7.5, no CO2.
Overview
Windelov Fern (Microsorum pteropus 'Windelov') is an aquatic plant of the family Polypodiaceae, listed in the Aquairi knowledge base as a beginner-level species. It is typically grown under low light and without obligatory CO2 injection on hardscape (epiphytic attachment to wood or rock; no substrate required). A beautiful cultivar of Java Fern with uniquely branching leaf tips that create an intricate lace-like appearance. Just as hardy as the standard Java Fern but with a more ornamental look, making it a popular choice for attaching to driftwood.
Taxonomy
- Family: Polypodiaceae
- Genus: Microsorum
- Scientific name: Microsorum pteropus 'Windelov'
- Common synonyms: Windelov Java Fern, Lace Java Fern
Habitat
Microsorum pteropus (Java fern) is a tropical fern of South-East Asia growing on rocks and tree roots in streams and waterfalls, frequently above the waterline. In the Aquairi knowledge base, populations associated with this form are recorded from cultivated.
Growth requirements
- Lighting: low
- CO2: not required
- Temperature: 20-28 °C (68-82 °F)
- pH: 6-7.5
- GH: 3-12 °dGH
- Substrate: not applicable (epiphytic attachment to hardscape)
- Maximum height: 20 cm
- Growth rate: slow
- Recommended placement: epiphyte on wood or rock
Placement
Must be tied or glued to wood or rock — the rhizome rots if buried. Tolerates a wide range of light from low to medium intensity. In the Aquairi knowledge base this form is recommended for the midground as an epiphyte on hardscape under low light and without obligatory CO2 injection, using no substrate (epiphytic attachment to hardscape).
Propagation
Reproduces by rhizome division and by plantlets that form on the underside of mature leaves; detached plantlets can be attached to new hardscape. Documented propagation techniques for this entry include: rhizome division, adventitious plantlets on flower stalks.
Common issues
Small black or transparent spots on older leaves are often signs of nutrient deficiency (especially potassium) rather than disease; affected leaves can be removed at the rhizome.
