The best temperature for growing chrysanthemum ranges from 20 - 280 C for day and 15 - 200C for night. Chrysanthemums are short day plant, which requires short days or long nights to flower. The critical day length is 14 - 15 hours for flower initiation and 13 -14 hours for development.
Any soil that permits good drainage and aeration is suitable for chrysanthemum. A medium consisting of 1 part compost, 1 part garden soil and 1 part animal manure or the combination of compost and coir dust, or rice hull or garden soil can be used. A pH of 6.0 - 6.5 is recommended.
