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