Chrysanthemum chrysanthemum prefers a cool and humid environment, and is not tolerant of cold, freezing, high temperature and humidity. After potting in September, pinch 1 to 2 times in the greenhouse in order to expand the crown of the plant. When cultivating on a closed balcony, the room temperature must be based on the conditions. It must be above 20°C during the day and not lower than 10°C at night, so that the branches will develop well after topping. If there is a reverse temperature difference, the branching rate will be poor, or even no germination. After topping, control the amount of watering. If possible, topdress 2 to 3 times. Stop fertilizing when buds are seen. Flowers will bloom from early spring to May of the following year.
