When to repot Aliceara Stellar

[Ray]

Such plants live as colonies. The more growths, the more sturdy and resilient the plant will be. I'd not divide that. If you must divide it, the general rule-of-thumb is one new-, plus two old growths at a minimum.

The best time to repot any orchid is just as new roots are emerging from the plant. Those new roots will support the plant as it gets established. Looks like you're very near that now.
