Ethylene Sensitivity: Oncidium orchids are sensitive to ethylene, which can cause flower shattering.
Temperature Requirements: They are sensitive to cold and should not be stored below 12–15 °C.
How to Avoid Potential Problems: Keep them away from ripening fruit and other sources of ethylene. Do not store in the plastic as this can encourage Botrytis growth; allow for good air circulation.
Hydration: Oncidium orchids require high humidity and thorough hydration without being waterlogged.
Avoiding Chilling Injury: These orchids are sensitive to cold and should not be stored in cool storage.
Botrytis Prevention: They are susceptible to Botrytis, a fungal infection; avoid wet conditions and ensure good air circulation to prevent outbreaks.
