Odontocidium 'Violetta von Holm Blanca': Post-Bloom Care & Repotting

ID: Odontocidium (Odontoglossum × Oncidium)

Cousins with similar needs. Trader Joe's/Nurserymen's Exchange source = mass-market but viable.

Post-Bloom

Cut spike at base, leave 1" stub. Won't rebloom on old spike.

Repotting: Bark Beats Dirt

Nursery "dirt" mix fails at home (no air to roots). Repot in fine orchid bark (thin roots). Same/next size pot. Spring ideal.

Culture (Bay Area)

• Light: Bright indirect; morning direct OK till noon; all-day winter sun OK.
• Temp: 50–85°F.
• Humidity: >40%.
• Water: Barely moist.
• Feed: Light balanced fertilizer several×/month.

Repot Steps

1. Water thoroughly first (eases removal).
2. Unpot; remove old mix gently (brittle roots).
3. Pot: mix base, center, fill, shake settle, press, top off.
4. Water; shade 2–3 weeks.
