If I understaing your problem you cannot replant a cattleya orchid. It's so easy. You most to cut the rhizomes in half and than plant
in the pot where the umidity it's to much.
It is a epiphite plant
and is native on tropical America. So cattleya orchids perform best in very high light and need a potting mix comprised of redwood bark chips, coarse charcoal or perlite, or other commercially available orchid mix. flowers
will not form if the plant
does not receive enough light. Cattleyas bloom only once a year, but the season of bloom varies by species or hybrid.
I help you?!
