Are the same plants grown throughout the year or are there seasonal variations? If yes, which plants are grown in which season?
Plants are not grown throughout the year in all nurseries as different plants have different seasonal requirements. Some plants flourish only in specific seasons because they require optimal temperature and humidity conditions. Nurseries can grow plants whenever required by creating suitable conditions, not only during naturally suitable seasons.
Explanation
The chapter mentions that the ideal temperature varies among plants, which is why some plants flourish only in specific seasons. However, since conditions for healthy growth can be created in plant nurseries, plants can be grown whenever required and not only during seasons that are generally suitable for them.
