Phalaenopsis Root Rot: Repotting in Fresh Bark Saves the Plant

One rotten root in a Phalaenopsis potted in wood-like media signals media breakdown. Immediate repotting in fresh bark prevents total root loss.

Immediate Repotting Steps

1. Buy orchid bark mix (fir bark, perlite, charcoal)
2. Soak portion while unpotting
3. Discard ALL old media (wood-like = decomposed)
4. Rinse roots thoroughly
5. Remove ALL mushy/collapsed roots
6. Plastic pot with abundant drainage holes
7. Pot size: fits roots, not larger
8. Repot with wet bark, drain completely

Why Wood-Like Media Fails

• Decomposed bark = fine particles = waterlogged
• No air spaces = root suffocation
• Progressive rot spreads to healthy roots

Post-Repot Care

• Water weekly (bark dries predictably)
• East window preferred
• Fertilize weakly weekly after new roots appear

Non-Phalaenopsis Note

If not Phalaenopsis, media and watering may differ. But bark-based mix in drained plastic pot works for most common orchids.

One rotten root is your warning. Fresh bark stops the rot cascade. Act now.
