What do I do with this phal?

[78Terp]

I believe this NoID phal is at least a hybrid with phal equestris having a dominate influence. I got it at the grocery store so I am doubtful it is a species orchid.

According to IOSPE:
"This species has a habit of making keikis and can rebloom out of old spikes and can continue to send off branches so they are best left uncut. They appreciate a drier winter although never left to dry out completely."

And thus lies my dilemma or lack of knowledge.

This phal had 1 keiki when I bought it. Also 2 spikes. Unfortunately, I didn't read the line about leaving the expired spikes. Back in those days, I cut phal spikes off unless I tried to rebloom them.

Now, it has 2 more keiki's in addition to the mother and the original keiki. I am certain the keiki's need to grow their own roots before even thinking of separating them.

Is that what should happen? Is it imperative to separate them or does this hybrid/species prefer to stay together? How about a drier winter?

This is its flower from February:


And this is the current plant. Quite healthy!
