Regular Problems With Java Ferns

Java ferns are anything but difficult to care for and keep up, however, they do every so often have a few issues if some water parameters or other ecological issues are off a piece.

In case you’re seeing your plants turning brown or black, going yellow or having different stains – past a couple of dead leaves, that is – you’ve presumably got some sort of issue moving on in your aquarium.

 Java Fern Turning Brown:

Some of the time, you’ll notice your Java fern turning brown. The brown spots at that point spread and devour bigger parts of the plant. This is an irresistible specialist that dynamically causes the disintegration of the plant.

At times, the leaf matter falls away and everything revives and is fine. On different occasions, it doesn’t resolve. This condition is brought about by a lack of supplements.

In the event that you see that the plant isn’t restoring, at that point, you need to check the nitrates and phosphates. There ought to be around 10 sections for each million – ppm – and 1 ppm, separately.

You may likewise need to add some calcium and magnesium to the water, which can regularly be given through aquatic plant manure. Or then again it very well may be finished with CaCO3, a calcium carbonate, which is accessible at nurseries, tank-farming stores on the web, some aquatic plant stores, or even home blending stores.

In any event, when a Java fern is browning out, it will deliver little unusual buds at the leaf edges. These infant plants can be isolated from the parent plant, even at a little size, and are suitable aquarium ferns that you can grow all alone.

It’s a smart thought to do this, particularly on the off chance that you notice a few of your Javas browning out this way.


In the event that your plants are creating yellow spots or in any event, liquefying/decaying ceaselessly totally from the stem, you likewise have a low supplement circumstance.

And keeping in mind that dosing isn’t typically essential, for this situation, including that fluid aquarium compost will help.

Burned LEAVES:

This one ought to be self-evident, yet in the event that you’re similar to me and need a smack to the face, burned leaves demonstrate you have a lot of light in your aquarium for these little ferns that favour dimmer settings.

The leaves might be turning brown – at the same time – or even straightforward and afterwards tumbling off.

In the event that this is occurring, you need to reposition your aquarium to dodge an excessive amount of light from different sources. You likewise need to change the light settings on your LED or change out your lighting arrangement for another one by and large – one that isn’t as brilliant.


There are two reasons Java fern black spots show up.

The first is a valid justification: new growth is coming! The little black spots on the underside of the leaves are the place the new growths are creating.

The second isn’t so extraordinary. In the event that you discover black spots springing up on your Java ferns and new growth isn’t coming, your plants likely have a nitrogen insufficiency. Once more, you’ll need to manage this by utilizing appropriately picked aquatic plant manure.

Step by step instructions to PLANT JAVA FERN

Java ferns are sensibly simple to plant. Yet, in case you’re thinking about how to situate them and how to grow Java ferns, at that point you’ll be satisfied to know there’s very little to it.
