Phalaenopsis Spike Dieback: Normal Genetics, Not Your Fault

Brown Spike Tips with Green Ends: The Internal War

A Phalaenopsis with yellow/brown spike bases but green tips shows genetic dieback fighting tip growth.

What to Cut

• Branched spike: cut just above the branching node.
• Unbranched spike: cut just above a node.
• If it continues browning, remove entirely at base.

Why It Happens

Some hybrids genetically die back after flowering. Others stay green and rebloom. Neither reflects your care.

Future Blooms

• Phalaenopsis bloom once yearly (spring).
• Strong plants may branch and rebloom on old spikes.
• Repot after flowering in fresh bark mix for next cycle.

Don't blame yourself. Follow the genetics, repot annually, and enjoy the flowers.
