Planting your Java Fern

The Java Fern doesn’t like its roots buried in the substrate and is very likely to grow extremely slowly, if not even die off if buried. It uses its leaves to absorb nutrients, so roots should be attached to pieces of wood or rocks instead of buried in the substrate.

You can do this by tying the roots with a piece of fishing wire, thread, rubber bands, or zip ties. Most aquarists prefer using thread, as it will dissolve over time and leave the roots fastened around the surface. Rubber bands and zip ties are easily noticeable, so you may want to remove them after the roots are secured.

In a few weeks, the fern should be firmly attached to the surface and start growing.

Due to its large size and wide leaves, this aquarium plant should be placed in the middle through background of the tank. Placing it in the foreground will hide everything else in the tank.

Tank Requirements

The Java Fern doesn’t require any special living conditions. It can be grown in tanks as small as 10 gallons with low light and water between 72-82 degrees Fahrenheit. Water pH should be between 6-8 and it can handle soft to moderately hard water.
