Care guide

Tight pot with fine-to-medium bark; many growers mount on cork slabs.

Spring after a cool, dry winter rest.
Bloom longevity
3–6 weeks; sprays can be very showy.
Growth habit
Sympodial, with tall cane-like pseudobulbs.
Propagation
Keikis form on old canes; remove with roots and pot up.
Pests & prevention
Aphids on new growth, scale on canes.
Signs of trouble
- ●No blooms → skipped the winter rest (cool + dry Nov–Feb)
- ●Leaf drop on bare canes → normal for deciduous types

Grower's tips
- ★Do not cut leafless canes — they store energy and may bloom again.
