Dividing a Phalaenopsis with Basal Split and Keiki

Your Phalaenopsis appears split into two plants at the base and has a keiki on a spike. Can you divide the base during repot and keep the keiki?

Base Division

Unpot. If two distinct plants, their root masses will untangle easily—no cutting needed. If they don't separate cleanly, it's one plant; repot as is.

Keiki Timing

Leave keiki attached until it has roots. No rush—some even bloom while attached.
