Wrinkled Cattleya Leaves: Old Growth vs. Root Rot

Diagnose by Leaf Age

Wrinkled leaves on old pseudobulbs = NORMAL (they feed new growth).
Wrinkled leaves on last year's growth = ROOT ROT likely.

Action for Suspected Root Rot

• Unpot to check—surface roots can look fine while lower roots rot in degraded mix.
• Repot in standard orchid mix (ideal timing: new growth emerging).
• Your new shoots = perfect repotting window!

Dendrobium Update

Rotting from cane bottom but new keiki at top? Save the keiki! Treat as cane cutting on damp sphagnum, seal cuts with sulfur.

Marita, your Cattleyas are signaling—listen to the new growth timing and repot now.
