How to care for Phalaenopsis?

[Taneoyee]

Hi Ladies and Gents,

Was given a phalaenopsis orchid, its beautiful, has three thick green leaves and to main shoots which have about 10 flowers on each!

I have just learned from after doing a search that I should not be watering the actual plant as it can rot!!

Only had it about a month, it has two other shoots which looked withered and dead - I have cut them? Not sure if I should have really!!

Just wondered if anyone has any advice and how often they should be repotted as this one looks like it may need it already!!

Thanks!
