In aquaristics, the java fern is considered an easy-to-cultivate plant. One that doesn't worry even beginners. This suggests that their care instructions do not contain any major challenges in the small print. Let's take a close look at that.
Java fern is a very easy-care aquarium plant
Provide ideal water environment
Allow the java fern to thrive in your home. Then it appears healthy and vigorous in bright green.
- provide the ideal water temperature
- from 20 to 25 degrees Celsius
- Observe degree of hardness
- medium-hard or hard range is optimal
If the ideal temperature values cannot be maintained, this does not mean the end for this aquatic plant. The java fern is surprisingly tolerant in this regard.
tips
The java fern needs a good supply of CO2 at all times. The easiest way to do this is to regularly change part of the water.
untie
A java fern should not be planted in sand or gravel at the bottom of the tank. The laterally growing rhizome does not tolerate digging, instead it has to be flushed with water.
Therefore, the first care step is the so-called tying up a newly acquired plant. If you are propagating Java fern from small offshoots, they will also need to be tied up at the appropriate time.
Place the java fern on a rock, root, etc., and tie it to it with fishing line or sewing thread until it can hold on with its own clinging roots. The yarn can then be removed again so as not to disturb the look.
light supply
A lamp in the aquarium supplies the plants living in it with light. The java fern also needs light, but it doesn't like it too bright. That's why it has to be placed in a shady or at least semi-shady area.
Fertilize
No special fertilizer is necessary, occasional iron supplements are sufficient. If he has too little of this element, black spots appear on the leaves. Then the undersupply must be compensated for by new fertilizer.
However, if the small black spots are round and have a diameter of about 2mm, they could be spore deposits.
Clean out Java fern
Leaves age and die. They have no place in a well-maintained aquarium. Remove them from the water promptly
