Phalaenopsis Spike Browning After Bloom: Normal Dieback

Repotted Phalaenopsis, Spike Browning: Don't Panic

Post-bloom repot, upper spike and parent stalk browning. Two other plants spiking.

Normal Genetics

• Most Phalaenopsis spikes brown from tip down after bloom.
• Browning stops at plant base—doesn't kill plant.
• Some hybrids stay green and rebloom.

Action

• Leave spike alone for months to see which type.
• If browns completely, cut at base.
• If stays green, may branch next season.

Other plants spiking = your culture works. This one's just following its genetics.
