When Should I Move Orchids Inside?

Orchids are sensitive to temperature changes, and the right temperature is crucial for blooming. Most orchids thrive in temperatures ranging from 75°F or more and 65°F or more. Temperature is generally not an indoor concern for homes that are climate controlled, but it is important to be cautious in the fall when the nighttime low reaches 55°F/12.7C for the first time.

Orchids prefer daytime temperatures of 75°F or more and nighttime temperatures of 65°F or more. In wintertime, this may not always be practical to achieve. Phals thrive when daytime temperatures range between 65 and 80°F, and nighttime temperatures drop slightly to between 60 and 70 degrees F. Generally, temperatures between 50° and 80°F (10° to 27°) are ideal for orchids; however, occasional brief periods of temperatures above 100°F (38 C) or drops even can help initiate flowers in many species.

Most orchids require at least 10°F to 15°F (12°C and 9°C) cooler at night to initiate flower spikes. In some places, the day/night variation is even bigger in some areas. Cymbidium orchids need cool conditions – a minimum of 10°C (50°F) – to flower. To ensure proper growth, it is essential to provide a distinct drop in temperature between day and night from the day to the night.

In conclusion, orchids are sensitive to temperature changes and require different temperatures for optimal growth. It is important to be cautious in the fall when temperatures drop below 50°F at night, as frost damage can be irreversible and potentially kill the plant.
