I just bought a new phal. It's in a 4" pot. The flower spike is
about 18" high with two branches. It has three beautiful large blooms
and about 12 buds. It has four large healthy leaves and is growing a
new one.

The pot is clear and I can see that it's absolutely filled with
roots. They are growing over the top and through the drain holes.
I'd say there's about 60 - 70% roots, the rest is bark.

I'm in a quandary. Should I leave it alone since it is doing so
wonderfully well or should I repot it so there can be more bark mix
for nutrients? I absolutely don't want to lose the blooms and buds.

Normally I repot my phals when the finish blooming. If they don't
need a larger pot then I just change the potting mix. If all goes
well it could be months before this phal stops blooming.

What should I do???

thanks
