Phalaenopsis Buds Drying Unopened: Annual Repotting Overdue

Two new spikes, many buds drying unopened. 12+ months orchids, first time. Water weekly. Where wrong?

Assumption: No Repot Since Purchase

Phals need annual repot in orchid mix after each bloom. If not, mix decomposes → soil-like → retains water, blocks air. Roots rot → nutrient flow drops → buds fail.

Immediate & Long-Term

  • Ease watering now to limit further root loss.
  • Repot after bloom: soak mix, remove mushy roots, fresh mix, drained pot.
  • Other factors: low humidity, <70°F, low light. Dark green leaves = insufficient light for bloom.
