if it has a tag, just tell us what the tag says...

in very general terms, the #1 reason an orchid would grow for two years
but fail to rebloom is insuffient light levels. The #2 reason would be
lack of fertilizer. BUT without knowing what kind of orchid it is, these
could be exactly the wrong answer.

also, depending on all sorts of unavailable data, if it has been in the
same pot for two years, it is probably way passed time to remove it from
the olde potting media and replace into some fresh stuff.
