I wouldn't cut any healthy roots,especially aerial roots.Only remove old

a slightly bigger pot might be necessary.No plant can stop in the same pot
for the rest of its life.What is the reason for the repot?

i was told that when they are in sphagnum moss they should be repotted every
year if not every 6 months.
they haven't outgrown the pots plus i have been feeding them too little (out of
ignorance)...
