Hi everyone! I have several posts already about my Java Fern but I can not grow this plant. Historically when I first bought it a year ago, it came with 7 leaves on driftwood. 5 weeks later the leaves growth in size with a lot of baby plants on them. A few months later, it stop growing. The leaves developed black spots and a few are now turning brown. It is weird for 1 year and it should be much more easier than stem plants I have in the tank.


What are the issues with it? Should I throw it away and buy new one or I should prune and remove all the leaves. Lighting is currently 3.3 wpg with DIY CO2.
 
Java ferns are low light plants... I heard of reports that high level lighting kills. I don't think it's true, just throwing it out there.

The water parameters would've helped.
 
Get rid of the leaves once they actually die. The black spots are pretty normal in high lighting. My fern in a 3 WPG tank has mostly brown leaves, but they are sprouting babies hardcore.
 
Wow is this true about java ferns in high light? Ouch no wonder...
 
I would not have made any complaint if it grows some more leaves. How can I get only 4 leaves left in one full year. I have just upgrade my light last week to 3.3wpg - before it was under 2wpg. Could it be sensitive to something such as fert?
 
dont know what happened to yours my tank is fullof em got a nice plant attached to driftwood a year ago now they almost cover the back of my tank and would have if i had not cut em down
 
I had mine in a tank of 2wpg and it turned black, I then stuck it in a tank that gets almost no light and its very green and healthy looking now, I brought it to the store for my shrimp to ride home on and the guy was shocked to see healthy java fern. theirs looks terrible
 
My first bit of java fern had about 6 leaves on it. It created a bunch of little ones on the leaves and started looking bad. It never actually grew at all. After a long time of this (it was alive, just not growing) I took the whole thing out, harvested all the daughter plants quite a few of them were growing rhizomes themselves by this point. I attached them to some driftwood. It was in a 15T with the standard hood and incandescents at the time. I then emptied that tank and had it in a filterless lightless 5gal for months. It was next to another tank with lights, but that was it. Now it's in my angel tank and I'll post a picture.

Not sure if that helps at all, but I think it illustrates that java fern almost wants to not get any extra attention as far as lights and fertilizers. Oddly enuff the original fern I bought did not have the lacy ends on the leaves.
