Runaway Cattleyas - when can I repot!?

[Les Barstow]

I purchased a Potinara (Hawaiian Prominence 'America') about 6 weeks ago. When I bought it it had two spikes in bloom and a new leaf starting up; it was a bit tight in/over the pot. Now I have at least TEN new growths spaced at least a month apart from many of the plant's bulbs, and the formerly new leaf has opened most of the way and is showing the tip of a new flower spike. Horrible problem, I know - but 23 pseudobulbs are *not* going to fit in a 4 inch pot! When do I repot it if I've got a new flower spike and existing (maybe 2wks left) flowers? Also, is it time to divide the plant already, or would it make a nice grand 6 inch display?
