Phalaenopsis Spike Pruning Genetics and Root Rot Rescue

Spike Behavior Is Genetic; Root Health Is Cultural

Spike pruning: Hybrids with dieback genetics will brown regardless of cutting. Only green spikes can rebranch (cut above 2nd–3rd node). Keiki paste won’t override genetics.

Root rot rescue: Your repotting steps were correct. Use fir-bark mix (sifted, soaked), well-drained pot, no moss. Remove all mushy roots. Green roots with black base—trim black portion. Consan soak helps. Bag with heat pad boosts humidity. Patience required.

Second plant: Different spikes on same plant can be at different phases. Keiki paste on lower node only works if spike stays green.
