How do I trim Cattleya after bloom

[cbloveday]

I bought 4 cattleya's in bloom and they were large so there were several bulbs which had previous stems cut and all that remained was a dried stem with wrap in emerging from the top of the bulb.
When my blooms died, I cut the flowering stem like the others, just above the bulb.

What if anything else do I need to do? Is this correct?

One of them which has like 7 bulbs has a fresh bulb which appears to have a stem emerging from it.

If pics are needed, I can supply tonight.

Thanks Curtis
