Cattleya Wrinkled Pseudobulbs and Black Spots: Root Rot and Rest Period

Your blooming Cattleya shows classic root rot signs: wrinkled pseudobulbs, black leaf spots, rippled leaves. It's entering a rest period—reduce watering and plan spring repotting.

Diagnosis: Root Rot + Rest Period

  • Wrinkled pseudobulbs = no root water supply
  • Black spots = fungal (water on leaves overnight)
  • Rippled leaves = dehydration
  • Yellow leaf = natural senescence (oldest)
  • Recent bloom = energy depletion

Immediate Care Changes

  • Water: Every 2 weeks + light misting between
  • Stop fertilizing during rest
  • Morning water only (prevents leaf spot)
  • Bright light, air movement continue

Spring Repotting (Mandatory)

  1. Timing: When new growth/roots emerge
  2. Media: Coarse orchid bark mix (very open)
  3. Pot: Clay preferred (breathability, weight)
  4. Support: Rhizome clips + bamboo stakes
  5. Process: Remove all dead roots, position oldest pseudobulb at rim

Cattleya Culture Summary

Your Cattleya bloomed despite root issues—impressive. Spring repot in coarse bark in clay pot will restore vigor for years of blooms.
