Odontoglossum Misidentified as Dendrobium: Post-Bloom Care

Photo ID Reveals Odontoglossum Alliance

Not Dendrobium. Flowers dropping = natural end (4–8 week bloom life). South window LA = too bright (yellow edges = sun stress). Pesticide on flowers may have accelerated drop.

Corrected Care

• Bright indirect (sheer curtain).
• 50–85°F, >50% humidity, air movement.
• Water barely moist; feed ½ strength spring–summer, ¼ winter.
• Never bone dry.

Post-Bloom

Cut spike at base + 1–2". Aphids? Squish or blast with water—no pesticide on blooms.

Genus Nuance

Odontoglossum alliance has many intergenerics; care similar with minor variations.
