Phalaenopsis Spike Browning: Genetics, Not Neglect

Natural Spike Dieback

Some Phalaenopsis hybrids genetically brown their flower spikes after blooming. Cutting them off harms nothing. The grower's east-window, humid bathroom culture is actually ideal.

Critical Missing Step: Annual Repotting

Repot after every bloom cycle in fresh, fir-bark-based mix. Soak mix first. Rinse roots, discard mushy ones. Use plastic pot with many drainage holes. Water weekly; feed ¼ tsp fertilizer per gallon at each watering once new growth appears.
