[BR@NDI LOVE'S PHAL'S]

Hi i have four phal orchids the first i got was from home depot already in bloom...(and me being an ammature)...i removed the plastic container it came in (with spagnum moss) and placed it in an 8' pot with gubler orchid bark and hardly any drain holes...I even watered it thats what the gal from garden center said to do...i later started researching and found everything ive done is WRONG!!!the roots got ugly and slimy..And soooo..(.now it gets really bad)i peeled off the ucky parts to the roots leaving only the stringy lookin roots?The leaves are still green...Is IT RUINED???BE HONEST...EVEN IF IT HURTS??

THANKS,
