RL7836 is a wizard when it comes to sect. Orchidioides utrics so definitely listen to his advice!
As mentioned
U. alpina is an epiphytic species that really does not appreciate the super wet, peaty mixes most terrestrial
Utricularia are grown in. The standard prescription tends to be live sphagnum or some mix of long-fiber sphagnum (I use 1:1 with perlite) though I've seen it grown in other mixes. Like others in the section it doesn't like hot temps, so you'll probably want to keep it as an intermediate or highlander.
