I have been growing u.gibba for a couple of months now. I still dont have too much of it & I'm finding it a real pain because the algae keeps swamping it.
Anyway, these past days I have noticed that nearly all of the bladders on it (just the bladders - none of the rest of the plant) have gone black. I grow it in a tub with peat on the bottom, covered by a layer of sand, then filled with an inch or 2 of water over that.
Does anyone have any ideas why this could be happening? I thought it might be sand in the bladders at first, but I dont think it is though.
Thanks & best regards,
