I'm having a problem with two of my sundews, a spathulata and a capensis. I've had them since April.
The spath is dewless, and the leaves look bad, but it is sending up a nice green flower stalk. *The capensis is dewy enough, but it is growing very slowly and looks like it ought to be greener--no flowers.
They are kept in a tank with two neps, a ping, an adelae and a diels. *All are doing great--really great--except for those two. *The neps have big (for new plants, anyway), colorful pitchers, the diels has a flower stalk that has had 8 blooms on it, the adelae is groaning with dewy goodness and three flower stalks. *The ping has a nice, purple flower on it and is producing lots of new leaves.
I've fed them, once a month, with dried insects caught by the light hood, and gnat-sized bits of dried tubifex. *(An occasional ant has gotten in the tank, with bad results for the ant--the neps really take off on that diet!
Av temp is about 80. *Av humidity is about 80. *Getting light, all artificial, 16 hours a day. *No fungus. *No mold. *No bugs. *Tray method for water. *Mix of LFS, perlite, peat. *Distilled water.
Too much light? *The other plants don't show any sign of it.
I am bewildered. *TIA, as always.
PS--As the spath was still in its original grower's soil, which has proved too rich in the past (red worm infestation), I have repotted it in hopes that I might reverse the decline. *The soil smelt fishy, so I think I did the right thing, but it is too soon to tell if it will help.
