Phalaenopsis Keiki and Flower Spike Behavior: Light Response

Keiki Impact

Mother plant won't die from keiki unless it's weak (few small leaves). Strong plants support keikis that may even bloom while attached.

Nodes produce keikis or branches based on light: more light → flower branches; less light → keikis.

Increase light for non-bloomers. Try different conditions for each. Results may show next winter/spring.
