I'm New to this Orchid thing:)

[Orchidnewbie1]

Ok here we go. I bought my first Orchid and it's, you quessed it, an Ice Orchid. I know, what a goof ball but I am looking forward to trying Orchids. They are so beautiful. Anyway, I plan to water it by soaking in warm water. Not ice. Question is, with what and how ofter do I fertilize. I know they make Orchid food but can I use any plant food? Also, my Mom has an Orchid that bloomed once a year ago and I checked the roots but there were non so I cleaned it up and help her keep it watered. Still won't bloom but it's alive. Any help would be appreciated. Thanks
