Hi, my java fern has black spots on its leaves, but i know that they are not reproductive organs, as they are actually pieces of he leaf tissue. Also, will micro, macro, and iron ferts get rid of this problem? What are the tiny ones that looked like they were attached to the plant? Thosse were interesting. I just whant to know what is the defficiency of the plants, to make them have black spots on them. My anubias has black tips, and has large black spots on it. I will post a pic on this JF and Anubias(im not sure if it is though.......Hopefully someone will know what the plant is.)

Hi,
Fertilization should not be a problem in a low light tank unless you have some real fast growers that can consume all the nutrients in the water column before the slow growers like anubius and java fern can get them. I hope you haven't buried the rhizomes. If the rhizome is buried, the leaves will turn brown and the plant dies.
If you can see tiny plants attached to the leaves of JF, they must be the fernlets. A photo should confirm that.

I didnt bury the rhizome, but i think my LFS did, and that might have doomed it? is the plant still salvageable? I need all the help i can get! Thanks!

Hi,
As long as the rhizome is firm and not spongy or soft
to the slight squeeze, the plant should be fine.
Remember, this is a slow growing plant you will not
immediately see new leaves growing. Additionally, whenever
you move a plant such as you have, from one tank to
another, the plant has to acclimate itself to its new
habitat. It will grow new roots and new leaves while the
old leaves will yellow and die off. In a stem plant and
some heavy root feeders such as the sword plants this
process is rather fast, and you can see in happening over
a two to three week period. In some slow growing plants
it can take longer. When you purchase or receive a new
plant, you should wash it under running water of the same
temperature as the tank water, removing old, dead, roots
and any damaged, dieing leaves, and any snail eggs.
Then you should plant it, once, where it is supposed to be
in your landscaping scheme. Planting a plant, then
uprooting it later injures the plant and the roots and can
cause it to take even longer to recover, if it will.

Hi, my java fern is doing better, and the rhizome is nice and hard. It is still kinda small, and the leaves are all green and <4" ;long. Will i need to Remove the string after it grows around the rock?

How large can a regular Microsorium pteropus take to grow? Also, the little black specks on it, will they grow to be fernlets? Well, thanks again, and i like the advice you gave me, and Need to know if the java fern is a hardy plant.

Hi,
Most folks will use a cotton fishing line or string
to hold the plant in place on driftwood or even a rock.
Leave the string in place, and over time the plant will
grow over the string, hiding it, and the string will
eventually rot away leaving the plant well anchored.
This is NOT a fast process. Put the plant where you
want it, tie it down, preferably with black cotton
sewing thread, and then leave it alone.

The plant is a very hardy plant and needs little care.

I ran in to the same problem a while ago. and it progressed the spots eventually consumed the whole leaves. Right now all I have are the rhyzomes. they are healthy and have new growth. Be patient. Oh and Listen to Frank. He helped me figure this out before.
