Cattleya species culture questions

[Greenthumb.5]

I have a Cattleya maxima that has one sheath on a pseudobulb but succumed to rot but I cut it off before it could spread but the other pseudobulbs are worrying me a little. Now there is no new growth so how would I encourage it to grow as I just repotted into new media.

And I also have Cattleya intermedia var aquanii coerulea(sorry if the spelling is wrong) but I would like your insight as I live in hot Georgia. Should it be repotted or when it should be repotted.

Any opinion and advice would be greatly appreciated and I would like to know any culture requirements for these species. And how you would bloom them. Also I would like to see any Cattleya species if you have them.
