I repot my phrags every 6 to 9 months - depending on the growth and media break-down. I no longer use bark, with phrags the growth was slow and mold showed up.
Now, I use sphagnum moss (for moisture) & perlite (for drainage & air)
Yours is a wet growing phrag,
Don't allow this one to dry-out keep this one wet. Water the media throughly and keep some water in a saucer for it to sip. Keep it moist.
Phrags will not
grow and bloom well at all if allowed to dry out for days on end.
