Commercial Floriculture

Climate

• The crop is best suited for cultivation in tropical to subtropical and temperate climates.
• The crop is reported to flower profusely through¬out the year, if the climate is mild and free from extremes of high and low temperature.
• A temperature range from 20-30°C is considered ideal for this crop.
• If the temperature is above 40°C, the spike length and quality of the flowers are affected.
• Very low temperature and frost will damage the plants and flowers.
• Tuberoses grow well in a sunny situation.
• Although the plant is photosensitive, exposure to a day-length of about 16 hours appreciably promotes vegetative growth and enhances the emergence of the first flower-spike by 10 days.
• The length of the flower-spike also increases under long days.
