I have a phal that I have owned almost 1 year. I bought it in flower and
anticipate that it is getting ready to flower again.

Here is the issue:

Over the last year, it grew 3 new leaves, much larger than the original
leaves on the plant. Three original leaves turned yellow and fell off. (I
have only 1 original leaf left) There were some surface roots that dried up
and died. I am using a clear plastic pot and can see good roots down
inside. Media is moss which I try not to get too dried out, but water only
when it appears to need it (once a week). Phal grows in the house in about
80 degree weather. Humidity is like around 30%.

Is this "normal" for roots exposed to air to die yet roots in the media to
do fine. Are leaves associated with unique roots? Could you say that the
new leaves were due to the good deep roots and the dead leaves due to the
dead surface roots? I know I have the plant growing in a warmer and drier
environment than where it was purchased. I bought it at Normans
(orchids.com) and when I took a trip to his nursery yesterday, the
environment was cool (70 and humid 45%). I am not going to try and
duplicate that environment in my house, but my Phal seems to be doing OK
even with the roots and leaves as I describe.

Comments?

Thanks
