I got a NoID phal in June in bloom. All of the blooms are gone and this is the point when I usually kill my phals. Talk me through the next steps so I don't kill this one. Should I repot it. It is still in the same pot/planting medium from when I got it. What about the spike? Cut it, if so where or leave it. Please help! I have read through the phal sticky but still afraid to do anything. Thanks!
