How to Care for Windelov Java Fern

— Use low lighting between 10-20 PAR. Too much light may cause burning or excess algae growth, so if you are using a brighter light, consider placing the java fern further away from the light or under the shade of taller or floating plants.
— Why is my java fern turning brown? It may be a nutrient deficiency, so measure the nitrate level using a multi-test strip. Dose with Easy Green all-in-one fertilizer until the water has 20-50 ppm nitrate. If the java fern continues to grow poorly, consider dosing Easy Potassium fertilizer in addition to Easy Green for extra potassium.
— How to trim Java fern: If the java fern has dying or melting leaves, trim them off at the base of the leaf without damaging the rhizome.

How to Propagate Windelov Java Fern

— Use a sharp pair of scissors to cut the rhizome and split into two plants. Plant the two sections as normal.
— Another method is to trim off a leaf from the base and leave it in the tank. The dark dots on the leaf will grow into individual, little plantlets that eventually can be planted or moved to another tank.
