Dendrobium Terminal Leaves Fail to Open: Mechanical Help and Rot Prevention

You've grown Dendrobiums 10 years. New terminal leaves won't open; mechanically tearing leaf edges helps. Inflorescences also choke. Cause and solution?

Rare Issue—Not Fatal

I've heard of this but don't recall the cause. If other leaves open normally, plant is fine.

Precautions

• Avoid water trapping in unopened leaf (causes rot).
• You can gently split the leaf open—no harm done.

Monitor and Continue Good Culture

Not a systemic problem. Mechanical assistance is acceptable workaround.
