Re:E. diversilfolia

Your blackening is a commonly occurring symptom. Anyone that has this plants
for a period will see this.
This plant needs PO4. I could not grow it until I added PO4 to the tap water
here which has no PO4.
Root and stem damage can cause this. If your careful where and how you plant
these cuttings you can avoid this somewhat. If it's crowded too much it will
get black on the lower leaves. I suppose this is a good thing for the plant
since it blacks out the competing plants and the blacked leaves don't rot
and last for a very long time allowing the growing tip to continue to get

The blackening also seemed to occur when Stargrass was also in the tank. It
was a 20 gallon and a fair amount of each was in the tank and the tank had
50%+ weekly water changes. A larger tank might get away with it.

First you have to be able to grow non blackened plants to gauge any causal
response from Stargrass. Stargrass had no distress signs when I did this(4
times when I said to heck with it due to the fact it took 3 months to get he
E. d. looking good again after each trial). It's entirely possible that
something else is going on but I don't think so. I had those stands of the
Ed. going great when I did this each time. I was like that dumb kid that
sticks his tongue to the icy flag pool(I tried a fence by the side

A poor pruning job can cause the plant to blacken also.
