Why are orchids more difficult to grow indoors than many other houseplants?

Orchids are considered more demanding than many other houseplants because they are primarily grown for their flowers, which often require specialized environmental conditions that are difficult to replicate in a typical home setting.12

Successful cultivation of orchids indoors is challenging due to their specific needs for:

• Light: They often require high light intensity that may not be available in standard living spaces.2
• Temperature: Many species require specific day-night temperature differences to thrive, which are not usually present in a home environment.2
• Humidity and Ventilation: Orchids generally require higher levels of humidity and consistent air circulation to remain healthy.2

While some houseplants are well-adapted to the warm, dry conditions of indoor living, orchids often perform better in greenhouses, where temperatures can be strictly regulated—such as in an intermediate house or hothouse—to meet their precise biological requirements.132
