Paphiopedilum rot

[meridiannight]

Today I discovered a rot on my only Paphiopedilum.

It had been very slowly developing, with next to no outward signs of trouble. There was one brown spot on a leaf, but it had been small until now, and didn't look problematic (came like that from the nursery). Only in retrospect do I see its significance. (The spot looked like Erwinia).

Anyway, the leaves all look completely healthy except for that single one with a spot that I removed. It was crown rot at the base, deep down in the potting media. Rotting media was surrounding the base of the plant and the roots down there. It didn't become visible until I took the plant out of the pot. I removed most of the roots, saved a few. Sprayed it with hydrogen peroxide. Cut the flower spike and potted it into a new pot. No idea if it's going to survive...

Oh, and some little black bugs (winged) had been living in the potting media as well.

This Paph has been with me for a month, and I really like it. Any suggestions on how to treat it now, to increase its chances of survival?
