New P. Taida Salu 'Sunset" in NZ Spag

[Eyebabe]

You probably will not loose the blooms if you repot but why are you so anxious to do so?
The sphag is already there and "used". If you can see that the roots are doing fine then just enjoy the blooms and repot when they are done.
And even if the plant is "fine" now and begins to have difficulty later then repot at that time.

I repot if I think the plant needs it eminently, if not then I enjoy the blooms and repot afterward.
