Phal Blooms Dropping All At Once

[KristenJ]

Hi all,

I have a Phal that has been in bloom for a few months now. It has just finished growing a leaf. It is currently growing several aerial roots. The roots in the pot all look good. Last year, this orchid dropped its blooms one at a time (which most of mine seem to do). However, today I checked on it and all of the blooms are shriveled up. There appears to be no damage or insects of any kind anywhere on this plant, or on Phals around it.

I am wondering if this is normal or if I should check for bacteria/fungus/other problem indicators?

Thanks!
