If you are already using a nutrient package, make sure it has iron in it. Iron is the nutrient that keeps the leaves green in java fern. You should use iron supplements in your water in order to fill the iron gap. In most cases, it is Iron deficiency that causes the leaves to turn brown. Since java fern is not planted on a substrate, leaves acquire nutrients from the water. Let’s see what causes the leaves to become brown and what can be done to prevent it- Reason 1: Lack of Nutrientsīrowning of leaves can occur due to a lack of nutrients. Whenever the leaves start turning brown, they are seen to shrink a bit.

Now, this browning might be full leaf browning or some portions of it. In this phase, the leaves start to lose their green color. For example, use iron supplements if you are facing iron deficiency. So according to which nutrient deficiency your plant is facing, use those supplements. And if the entire java fern has turned yellow there’s iron deficiency. Thirdly, it’s facing potassium deficiency if there are yellow pinholes on it. Here dead patches are seen added to older yellow leaves. If only the older leaves are turning yellow, this is phosphate deficiency. If there are both new and old leaves turning yellow, it’s facing nitrogen deficiency. If they’re not exposed to light, the leaves can turn yellow. The first thing to do here is to make sure the rhizomes are not covered anyhow. It’s caused by nitrogen, iron, potassium, or magnesium deficiency. It occurs due to a lack of necessary nutrients. When it turns yellow, it can be gained back to green. Java fern is seen to turn yellow and have pinholes in it. So the best bet is to wait a day or two to see if they are sprouting new plants or not. However, if no new plants are sprouting from these black spots, they are likely to die.
So don’t get afraid upon seeing black spots on them. Often java fern has young plants sprouting from these black spots.
Java Ferns are often seen to have black spots on them. So let’s see if these colors actually mean they are dying or not- Seeing Java Fern Black Spots Well, sometimes people tend to get afraid the moment they see their fern turning yellow, brown, transparent, etc. Now the question comes if your java fern is really dying or not.
