spike black on tip of phal venosa

[ladyslipper]

Hi guys, the spike that my phal venosa started months ago had stopped growing awhile back but I thought it stopped maturing because I moved the plant. Its now clear that the spike is likely dead (it has a bit of black on the flower end).

I don't know why it has happened. The plant is growing roots and leaves and when I checked the repot tag, it was repotted in March /07.

I am pretty sure I should cut the spike back, but how far and what else do I need to do.

Any thoughts would be appreciated.

many thanks, mary
