Not sure, I didn't really feed mine anything, it's actually in a little 16oz cup filled half full with a loose soil and with no drain holes, I had some in richer soil and they didn't do nearly as well, it seems to thrive all by itself, the less attention payed the better, so as far as how to stop it from blooming I'm at a loss, because I certainly didn't do anything to intentionally make mine bloom haha
