I had the phals in bloom and did fine...is when they start dying off is after they bloom and I repot them..I think I know why now after reading up on Rays free info link. The aerial roots I covered up..The problem was that all the roots in the pot STARTED as aerials from the top and worked they way down into the pot. I covered up effectively killing the roots in the pot bec I smothered the aerial roots on top..Learned..
In fact, one I buried the aerial roots on and it popped out 4 more aerial roots..So no more covering up the aerial roots when they need repot for me...
These are doing really good for a phal killer.
there maybe some hope for me enjoying them in the future after I figure all this out and stop killing them
